Find A. If Necessary, Round Your Answer To The Nearest Hundredth. Sorry The Picture Was Upside Down.

Answers

Answer 1

Answer:

The answer to your question is a = 4.81

Step-by-step explanation:

Process

1.- The angle B and 43° are supplementary

            B + 43° = 180°

            B = 180 - 43

            B = 137°

2.- Calculate angle C

The sum of the internal angles in a triangle equals 180°

     A + B + C = 180°

      29 + 137 + C = 180

- Solve for C

     C = 180 - 29 - 137

     C = 14°

3.- Use the law of signs to find a

            a / sin A = c / sin C

           a / sin 29 = 2.4 / sin 14

- Solve for a

           a = 2.4 sin 29 / sin 14

- Simplification

           a = 2.4 (0.485) / 0.242

- Result

           a = 4.809

Answer:

The answer to your question is QG = 55.8 ft

Step-by-step explanation:

Data

QG = x

Process

1.- Find T

The sum of the internal angles in a triangle equals 180°

          G  +  Q  +  T  = 180

-Solve for T

            T  =  180 - G  -  Q

- Substitution

            T = 180 - 41 - 67

-Simplification

             T = 72°

2.- Use the law of sines to find QG

              QG / sin T = GT / sin Q

-Solve for QG

              QG = GT sinT / sin Q

-Substitution

              QG = 54 sin 72 / sin 67

- Simplification

              QG = 54 (0.951)/0.921

-Result

             QG = 55.8 ft        

Answer:

Step-by-step explanation:

Considering the given triangle QGT, to determine QG, we would apply the sine rule. It is expressed as

a/SinA = b/SinB = c/SinC

Where a, b and c are the length of each side of the triangle and angle A, Angle B and angle C are the corresponding angles of the triangle. Likening it to the given triangle, the expression becomes

QG/SinT = GT/SinQ = QT/SinG

The sum of the angles in a triangle is 180°. It means that

T = 180 - (41 + 67) = 72°

Therefore

QG/Sin72 = 54/Sin 67

Cross multiplying, it becomes

QGSin67 = 54Sin72

0.921QG = 54 × 0.951

0.921QG = 51.354

QG = 51.354/0.921

QG = 55.8 ft

Twin brothers, Billy and Bobby, kid mother grandparents lawn together for 60 minutes. Billy could mow the lawn by himself in 20 minutes less time then it would take Bobby. How long will it take Bobby to mow the lawn by himself

Answers

Answer:

Bobby around 131 minutes and Billy around 111 minutes

Step-by-step explanation:

To solve the problem it is important to raise equations regarding what happens.

 They tell us that Billy (Bi) and Bobby (Bo) can mow the lawn in 60 minutes. That is to say that what they prune in a minute is giving as follows:

1 / Bo + 1 / Bi = 1/60 (1)

They say Billy could mow the lawn only in 20 minutes less than it would take Bobby, therefore

1 / Bi = 1 / (Bo-20) (2)

Replacing (2) in (1) we have:

1 / Bo + 1 / (Bo-20) = 1/60

Resolving

(Bo - 20 + B0) / (Bo * (Bo-20) = 1/60

120 * Bo - 1200 = Bo ^ 2 - 20Bo

Rearranging:

Bo ^ 2 - 140Bo -1200 = 0

Now applying the general equation

Bo = 130.82 or Bo = 9.17, this last value cannot be because Billy took 20 minutes less and neither can he prune faster than the two together, therefore Bobby only takes around 131 minutes and Billy around 111 minutes

Checking with equation 1:

1/131 +1/111 = ~ 1/60

Final answer:

Bobby would take 120 minutes to mow the lawn by himself.

Explanation:

The question asks us to calculate how long it will take Bobby to mow the lawn by himself if it takes his twin brother Billy 20 minutes less to do the job on his own, and they can mow the lawn together in 60 minutes. To solve this, we can use the concept of work rate and the idea that the combined work rate of Billy and Bobby equals the reciprocal of the time they take to work together.

Let's assume Bobby takes x minutes to mow the lawn by himself. Thus, Billy would take x - 20 minutes. We can express their work rates as:

Bobby's work rate: 1/x lawn/minuteBilly's work rate: 1/(x - 20) lawn/minute

The combined work rate when they mow together is the sum of their individual work rates, which is equal to 1/60 since they take 60 minutes together. So, we have:

1/x + 1/(x - 20) = 1/60

By solving this equation for x, we find the time it takes Bobby to mow the lawn by himself.

Multiply through by 60x(x - 20) to clear the denominators:60(x - 20) + 60x = x(x - 20)60x - 1200 + 60x = x^2 - 20xCombine like terms:x^2 - 140x + 1200 = 0Solve for x using the quadratic formula or by factoring:(x - 120)(x - 10) = 0Therefore, x = 120 or x = 10. Since x has to be greater than 20, x = 120 is the correct solution.

Hence, Bobby will take 120 minutes to mow the lawn by himself.

Answers

Answer:

a) Rate of change of amount

[tex]A'(t) =110e^{0.055t}[/tex]

b) &170.79

c) 0.21

Step-by-step explanation:

We are given the following in the question:

The balance is given by the equation:

[tex]A(t) =- 2000e^{0.055t}[/tex]

where t is the time in years and the initial investment is $2000 when compounded continuously.

a) Rate of change of amount

[tex]\dfrac{d(A(t))}{dt} = \dfrac{d}{dt}(2000e^{0.055t})\\\\\dfrac{d(A(t))}{dt} = 2000e^{0.055t}\times 0.055\\\\\dfrac{d(A(t))}{dt} =110e^{0.055t}[/tex]

b) We have to find the value of A'(8)

[tex]A'(t) =110e^{0.055t}\\A'(8) = 110e^{0.055(8)} = 170.79[/tex]

Interpretation:

The future value of 9 year investment of $2000 will be $170.79 more than the future value of 8 year investment.

c) Comparison

Approximation = $171

Actual change = $170.79

Difference =

[tex]\text{Approximation - Actual change}\\=171 - 170.79\\=0.21[/tex]

Thus, the error is 0.21

Final answer:

The formula for dA/dt is 2000(0.055)e^(0.055t). A'(8) is found by substituting t=8 into dA/dt. To compare the approximation of $171 to the actual change, subtract the initial investment from the new balance after 8 years.

Explanation:

a. To find the formula for dA/dt, we differentiate the equation A(t) = 2000e^(0.055t) with respect to t. Using the chain rule, we have dA/dt = 2000(0.055)e^(0.055t).

b. To find A'(8), we substitute t = 8 into the expression for dA/dt. Plugging in the values, we get A'(8) = 2000(0.055)e^(0.055(8)). This will give us the rate of change of the balance after 8 years.

c. To compare the approximation of $171 to the actual change, we subtract the initial investment of $2000 from the new balance after 8 years. The approximation is $171, so the actual change is A(8) - 2000. Plugging in the values, we get A(8) - 2000 = 2000e^(0.055(8)) - 2000.

Mt. Vesuvius has an altitude of 3000 feet. A person stands 120 feet away from the base of the volcano. What is the angle of elevation from the person on the ground to the top of the volcano?

Answers

Answer: the angle of elevation from the person on the ground to the top of the volcano is 87.7°

Step-by-step explanation:

The person, his angle of elevation and his distance from the foot of the mountain forms a right angle triangle.

The altitude of the mountain represents the opposite side of the right angle triangle.

The distance of the person from the base of the volcano represents the opposite side of the right angle triangle.

To determine the angle of elevation from the person on the ground to the top of the volcano, we would apply the tangent trigonometric ratio.

Tan θ, = opposite side/adjacent side. Therefore,

Tan θ = 3000/120 = 25

θ = Tan^-1(25)

θ = 87.7° to the nearest tenth.

Linda Johnson, a broker, sold a home for $85,000. The home had been listed with another real estate firm for a 7% commission. The commission split between Johnson's principal broker and the other principal broker was 50/50. The commission split between Johnson and her principal broker was 65% to the broker, 35% to the principal broker. What was Johnson's commission from the sale of the home

Answers

Answer:

Linda's share was $ 1933.75

Step-by-step explanation:

We first need to calculate the comission that was paid to the other real state firm wich is 7% of the sales price, so we can use the following equation:

Comission = 85000 * (7/100) = 85000*0.07 = 5950 $

Since this comission was split in half between Johnson's broker and the other broker we have 5950/2 = 2975 for each of them. From that value 65% should stay with the broker wich is Linda in this case so:

Linda's share = 2975*(65/100) = 2975*(0.65) = 1933.75 $.

Given Information:

Sale Amount = $85,000

Commission rate = 7%

Linda Johnson commission rate = 65% of 50% of commission amount

Required Information:

Linda Johnson share in the sale = ?

Answer:

Linda Johnson share in the sale = $1933.75

Step-by-step explanation:

Linda Johnson share in the sale is

Linda's share = 65% of 50% of commission amount

Where commission amount is

commission amount = 7% of sale amount

commission amount = 0.07*85,000

commission amount = $5,950

Linda's share = 0.65*0.50*5,950

Linda's share = $1933.75

Given:

- The ratings for current lives on a scale 0 - 10 were normally distributed with parameters mean (u) and standard deviation (s).

                                   u = 5.3

                                   s = 2.5

Find:

Find the probability that a randomly selected study​ participant's response was less than 4.

Solution:

- Declare a random variable X that follows a normally distribution with parameters u and s, mean and standard deviation respectively.

                                  X~N( 5.3 , 2.5 )

- To determine the probability of the rating to be less than 4 for a randomly selected study participant's response we have:

                                  P ( X < 4 )

- Compute the Z-score value for the limit given:

                                  P ( Z < (4 - 5.3) / 2.5 )

                                  P ( Z < -0.52 )

- Use the Z-Table to calculate the above probability as follows:

                                  P ( Z < -0.52 ) = 0.3015

- Hence, the required probability is equivalent to Z-score value probability:

                                    P ( X < 4 ) = P ( Z < -0.52 ) = 0.3015

                                 

The probability that a randomly selected study participant's response was less than 4 is 0.3015.

To find the probability that a randomly selected study participant's response was less than 4, we can use the properties of the normal distribution. Given that the mean is 5.3 and the standard deviation is 2.5, we can standardize the value 4 using the z-score formula: z = (X - µ) / σ, where X is the value of interest, µ is the mean, and σ is the standard deviation. Once we find the z-score, we look up this value in the standard normal distribution table (Z-table) or use a calculator to find the probability.

Step-by-step calculation:Calculate the z-score for X = 4: z = (4 - 5.3) / 2.5 = -0.52.Look up the z-score in the Z-table or use a calculator to find the probability that Z < -0.52.For a z-score of -0.52, the probability is approximately 0.3015 (found from Z-table or through calculator).

The probability that a randomly selected study participant's response was less than 4 is therefore 0.3015, or 30.15% when converted into percentage form.

There is 7/8 quarts of orange juice. Mrs. Mathewson would like to serve her guests 3/16 quarts orange juice. How many guests can she serve orange juice?

Answers

Final answer:

Mrs. Mathewson can serve orange juice to 4 guests. The solution was found by first converting the fractions to the same denominator, then dividing the total orange juice by the amount per guest, and taking into account that you can't serve fractions of a guest.

Explanation:

The problem presented here is a basic division problem that requires you to divide the total amount of orange juice by the amount served to each guest. Mrs. Mathewson has 7/8 quarts of orange juice and she would like to serve each guest 3/16 quarts of orange juice.

Firstly, we'll convert both fractions to the same denominator for simplicity. As 8 is a multiple of 16, we can leave the second fraction as it is (3/16) and change the first fraction to 14/16 (which is the same as 7/8). Now, we divide 14 by 3 which gives us roughly 4.6.

This result means Mrs. Mathewson can serve orange juice to 4 guests with a bit left over. As we can't serve a fraction of a guest, it means she can only serve 4 whole guests.

Answers

Answer:

34.8 liters

Step-by-step explanation:

He has 35.8 liters.

He uses 28.6 liters.

Now that tanks has 35.8 liters - 28.6 liters = 7.2 liters

The capacity of the tank is 42 liters, and he has only 7.2 liters.

The fill up will be 42 liters - 7.2 liters = 34.8 liters

Answer: he bought 34.8 liters of gas.

Step-by-step explanation:

Let x represent the number of liters of gas that Alberto bought.

At the beginning of the week, Alberto's car has 35.8 liters of gasoline in its tank. He uses 28.6 liters of gasoline during the week. This means that the number of liters of gas left would be

35.8 - 28.6 = 7.2

Then he completely fills the tank with gas. If the gas tank of Alberto's car holds a total of 42 liters of gas., it means that

x + 7.2 = 42

x = 42 - 7.2

70 goes into 240 evenly 3 times, and 70×3 equals 210. that leaves 30 miles remaining. since he is moving at an average rate of 70mph, 3/7 would be the remaining time. to decimal that equals a total of about 3 hours and 25 minutes, which, rounded up, equals 3 and 1 half hours.

One maid can clean the house in 2 hours. Another maid can do the job in 8 hours. How long will it take them to do the job working together?
A 16/6 hr
B 8/5 hr
C 1/10 hr
D 1/16 hr

Answers

Answer: B 8/5 hr

Step-by-step explanation:

One maid can clean the house in 2 hours. This means that the rate at which she cleans the house per hour is 1/2

Another maid can do the job in 8 hours. This means that the rate at which the other maid cleans the house per hour is 1/8

If they work together, they would work simultaneously and their individual rates are additive. This means that their combined working rate would be

1/2 + 1/8 = 5/8

Assuming it takes t hours for both of them to clean the room working together, the working rate per hour would be 1/t. Therefore,

5/8 = 1/t

t = 8/5 hour

Final answer:

Option B is correct. Working together, the two maids can clean the house in 8/5 hours.

Explanation:

Let's assume that the combined rate of both maids working together is x house cleaned per hour. We can set up the equation:

1 maid's rate + another maid's rate = combined rate

1/2 + 1/8 = x

Solving for x:

4/8 + 1/8 = x

5/8 = x

The combined rate of the maids working together is 5/8 house cleaned per hour. To find how long it will take them to clean the house together, we can set up the equation:

(5/8) house per hour = 1 house

Let t be the time it takes them to clean the house together. We can write the equation:

(5/8) * t = 1

Solving for t:

t = 1 / (5/8)

t = 8/5 hours.

Jerry says I've got my money in a great account that compounds interest monthly. The equation y=388 (1.008) represents how much money I have at the end of the month. What is Jerry 's monthly interest rate? What is his annual interest rate? Write an equation to represent your total money if you invest $500 in an account with the same rate of return .Let m represent the number of months the money has been invested

Answers

Answer:

(a)His monthly Interest Rate=0.8%

(b)Annual Interest Rate = 9.6%

(c)[tex]500(1.008)^m[/tex]

Step-by-step explanation:

For a Principal P invested at a yearly rate r, compounded m times in t years

Amount at Compound Interest= [tex]P(1+\frac{r}{m})^{mt}[/tex]

Comparing with Jerry's equation y=388 (1.008)

(a)His monthly Interest Rate= 0.008=0.8%

(b)Annual Interest Rate= Monthly Interest Rate X 12 =0.8 X 12 = 9.6%

(c)If I invest $500 at the same rate of return,

Total Money after m months

= [tex]P(1+\frac{r}{m})^{mt}[/tex][tex]=500(1+0.008)^{m}[/tex][tex]=500(1.008)^m[/tex]

Final answer:

Jerry's monthly interest rate is 0.8%, and his annual interest rate is approximately 9.96%. An investment of $500 in the same account would grow according to the equation [tex]y = 500(1.008)^{m}[/tex], where m represents the months invested.

Explanation:

Jerry says he's got his money in a great account that compounds interest monthly. The equation [tex]y=388(1.008)^{m}[/tex] represents how much money he has at the end of the month. The monthly interest rate is found in the equation inside the parentheses, 1.008, which means the monthly interest rate is 0.8% (since 1.008 is equal to 1 plus 0.008 or 1 + 0.8/100). To find the annual interest rate, we need to use the compounding formula, which for monthly compounding can be simplified to [tex](1 + monthly interest rate)^{12} - 1[/tex]. so, [tex](1.008)^{12}- 1[/tex] gives an annual rate of approximately 9.96%.

To write an equation representing your total money if you invest $500 in an account with the same rate of return, we use the formula [tex]y = P(1 + r)^{m}[/tex], where P is the principal amount ($500), r is the monthly interest rate (0.008), and m represents the number of months the money has been invested. Therefore, the equation is [tex]y = 500(1.008)^{m}[/tex].

Biking at 10 mph, it takes Kristen 1/2 hour to reach the train station to go to work. Kristen then takes the train to work, and it takes another 1/2 hour for her to get to work when the train travels 28 mph. How far does Kristen travel to work

Answers

Answer: 38 mph

Step-by-step explanation:

Add. 10 plis 28 is 38.

Answer: 19 miles

Step-by-step explanation:

Distance = speed × time

Biking at 10 mph, it takes Kristen 1/2 hour to reach the train station to go to work. This means that the distance covered on her way to the train station is

0.5 × 10 = 5 miles

Kristen then takes the train to work, and it takes another 1/2 hour for her to get to work when the train travels 28 mph. Distance covered by the train is

0.5 × 28 = 14 miles

Therefore, the distance that Kristen travels to work is

14 + 5 = 19 miles

  -540

Step-by-step explanation:

The coefficient of the k-th term of (a+b)^n is nCk. (k = 0, 1, 2, ..., n)

Here, we want the coefficient of a^3b^3 for n=6, so k=3 and the coefficient is ...

  6C3 = 6!/(3!(6-3)!) = 5·4 = 20

So for a=3x and b=-y, we want ...

A palindrome is a string whose reverse is identical to the original string. Give examples of bit strings of length 5 and 6 that are palindromes. How many bit string palindromes of length n are there? How many ternary string palindromes of length n are there?

Answers

Answer:

The answers to the question are as follows

a). Please see the examples of bit strings of length 5 and 6 that are palindromes in the following explanation.

b). The number of even length palindromes is [tex]26^{\frac{n}{2} }[/tex]

The number of odd length palindromes is [tex]26^{\frac{n+1}{2} }[/tex]

c). The number of  ternary string palindromes of length n is 702.

Step-by-step explanation:

a). Examples of bit strings of length 5 and 6 that are palindromes are

b). When n is even, we have a choice of any of the 26 characters for the first letter, similarly, we can choose any character for the second, and so on up till the n/2 th position after which subsequent letters depend on the letter chosen before the half point following the definition of a palindrome.

Therefore we have n/2 independent choices with repetition therefore we have [tex]26^{\frac{n}{2} }[/tex] palindromes of even length with or without meaning in the alphabet

On the other hand, when n is odd, we are free to chose any letter up to the middle letter as before this means we have [tex]\frac{n-1}{2} +1 = \frac{n+1}{2}[/tex] free choices

Therefore the number of odd length palindromes are [tex]26^{\frac{n+1}{2} }[/tex]

c). For a ternary string palindrome, we have 26 letters for the first position, and also 26 for the second, while the third is the same as the first which is one option.

Where n = 2 we have 26 ways of selecting the first and second letters which are equal

Therefore the number of  ternary string palindromes of length n  are 26×26 + 26 = 702

Final answer:

Bit string palindromes of length 5 and 6 are strings that are the same forward and backward, like '10101' or '100001'. The number of palindromic bit strings of length n is 2 raised to the floor of n/2, and the number of ternary string palindromes of length n is 3 raised to the floor of n/2.

Explanation:

A palindrome is a string that remains the same when reversed. Examples of bit string palindromes of length 5 include '10001', '01110', '10101', '01010'. For length 6, examples could be '100001', '011110', '101101', '010010'.

In general, to calculate the number of palindromic bit strings for any given length, the first half of the string can be anything (2 ⌊n/2⌋ possibilities), and the second half must mirror the first. Thus there are 2 ⌊n/2⌋ bit string palindromes of length n.

For ternary palindromes (strings composed of the digits 0, 1, and 2), use the same logic but switch the base to 3. Thus there are 3 ⌊n/2⌋ ternary string palindromes of length n.

You invest $3,200 in an account that pays an interest rate of 8.5%, compounded continuously.


Calculate the balance of your account after 6 years. Round your answer to the nearest hundredth.

Answers

Answer: the balance is $5328.95

Step-by-step explanation:

The formula for continuously compounded interest is

A = P x e (r x t)

Where

A represents the future value of the investment after t years.

P represents the present value or initial amount invested

r represents the interest rate

t represents the time in years for which the investment was made.

e is the mathematical constant approximated as 2.7183.

From the information given,

P = 3200

r = 8.5% = 8.5/100 = 0.085

t = 6 years

Therefore,

A = 3200 x 2.7183^(0.085 x 6)

A = 3200 x 2.7183^(0.51)

A = $5328.95 to the nearest hundredth

Find the value of each variable in the parallelogram

pls help:)​

Answers

Answer:

Step-by-step explanation:

In a parallelogram, the opposite sides are equal and parallel.

Also, consecutive angles in a parallelogram are supplementary. This means that the sum of the consecutive angles is 180 degrees.

Angle 2m and angle n are supplementary angles. Therefore,

2m + n = 180 - - - - - - - - - - - -1

Also, the opposite angle in a parallelogram are equal. This means that

2m = 70

m = 70/2

m = 35 degrees

Substituting m = 35 into equation 1, it becomes

2 × 35 + n = 180

70 + n = 180

n = 180 - 70

n = 110 degrees

The value of m and n are 35 and 110 respectively.

We are given that one of the angles of the parallelogram is [tex]70^\circ[/tex].

Since opposite angles in a parallelogram are supplementary, the angle directly opposite the 70° angle must be [tex]180^\circ -70^\circ = 110^\circ[/tex].

We are also given that one of the non-consecutive interior angles has a measure of 2m°.

Since consecutive interior angles in a parallelogram add up to 180°, the angle next to the 2m° angle must have a measure of 180°- 2m°.

The opposite sides of a parallelogram are congruent.

This means that n° must be congruent to 110°. So, n = 110.

We can now solve for 'm'.

Since the angle next to the 2m° angle must have a measure of 180°−2m° and this angle is also congruent to 110°.

We have the equation: [tex]110^\circ = 180^\circ - 2m^\circ[/tex]

[tex]2m^\circ = 70^\circ[/tex]

[tex]m=35[/tex]

Answer:

a) The Venn diagram is presented in the attached image to this answer.

b) 0.82

c) 0.16

Step-by-step explanation:

a) The Venn diagram is presented in the attached image to this answer.

n(U) = 100%

n(S) = 48%

n(B) = 66%

n(H) = 38%

n(S n B) = 30%

n(B n H) = 22%

n(S n H) = 28%

n(S n B n H) = 12%

The specific breakdowns for each subgroup is calculated on the Venn diagram attached.

b) The probability that a randomly selected student likes basketball or hockey.

P(B U H)

From the Venn diagram,

n(B U H) = n(S' n B n H') + n(S' n B n H) + n(S n B n H') + n(S n B n H) + n(S n B' n H) + n(S' n B' n H) = 26 + 10 + 18 + 12 + 16 + 0 = 82%

P(B U H) = 82/100 = 0.82

c) The probability that a randomly selected student does not like any of these sports.

P(S' n B' n H')

n(S' n B' n H') = n(U) - [n(S' n B n H') + n(S' n B n H) + n(S n B n H') + n(S n B n H) + n(S n B' n H) + n(S' n B' n H) + n(S n B' n H')]

n(S' n B' n H') = 100 - (26 + 10 + 18 + 12 + 16 + 0 + 2) = 100 - 84 = 16%

P(S' n B' n H') = 16/100 = 0.16
