For This Right Triangle, What Is The Cosine Of Angle C? A) 12/13B) 13/12C) 5/12D) 5/1350 Points, Again

Answers

Answer 1

Answer:

A  cos C = 12/13

Step-by-step explanation:

cos theta = adjacent side/ hypotenuse

cos C = BC/AC

But we don't know BC, but we can find it using the Pythagorean theorem

a^2 +b^2 = c^2

5^2 +BC^2 = 13^2

25 + BC ^2 =169

Subtract 25 from each side

BC^2 = 169-25

BC ^2 = 144

Taking the square root of each side

BC =12

cos C = 12/13

a tree is 8ft tall and grows 8 inches each year. In how many years will the tree reach a height of 30 feet?

A.27
B.33
C.45
D.52​

Answers

Answer:

B

Step-by-step explanation:

30 ft = 360 in

8 ft = 64 in

360 in - 64 in = 296 in

296 / 8 = 33

It will take approximately 32.84 years for the tree to reach a height of 30 feet.

To determine the number of years it will take for the tree to reach a height of 30 feet, let's break down the growth process step by step.

Initially, the tree is 8 feet tall.

The tree grows 8 inches (0.67 feet) each year.

Let's assume it takes "x" years for the tree to reach a height of 30 feet.

So, the height of the tree after "x" years can be represented by the following equation:

Height after x years = Initial height + (Growth rate * x)

In this case, the initial height is 8 feet, and the growth rate is 0.67 feet (8 inches).

Height after x years = 8 + (0.67 * x)

Now, we need to solve for "x" when the height reaches 30 feet:

30 = 8 + (0.67 * x)

Subtract 8 from both sides of the equation:

22 = 0.67 * x

To isolate "x," divide both sides by 0.67:

x = 22 / 0.67

Now, calculate "x":

x ≈ 32.84 years

So, the Answer: B. 33 years

Solve the system of equations y=8x+15 and y=x+57

Answers

Answer:

x=6, y=63

Step-by-step explanation:

since both equal y, they equal each other-

8x+15=x+57

7x=42

x=6

then to solve for y-

y=(6)+57

y=63

The solution to the system of equations y = 8x + 15 and y = x + 57 is found via substitution, yielding x = 6 and y = 63 as the answer.

To solve the system of equations y = 8x + 15 and y = x + 57, we can use the method of substitution or elimination. However, since both equations are already solved for y ,, the most straightforward approach is substitution, implying that 8x + 15 = x + 57. To find the value of x, we subtract x from both sides and subtract 15 from both sides, yielding 7x = 42. Dividing both sides by 7, we find that x = 6. Substituting x = 6 into either of the original equations, for instance, y = 8(6) + 15, gives us y = 63. Therefore, the solution to the system of equations is x = 6 and y = 63.

perform all the steps to evaluate this expression. (6^7)(3^3)/(6^6)(3^4) What is the value of the expression?

Answers

Final answer:

To evaluate the expression (6^7)(3^3)/(6^6)(3^4), simplify each term, resulting in 6^10 / 6^10, which equals 1.

Explanation:

To evaluate the expression (6^7)(3^3)/(6^6)(3^4), we can simplify each term first. The numerator can be simplified as (6^7)(3^3) = 6^(7+3) = 6^10. The denominator can be simplified as (6^6)(3^4) = 6^(6+4) = 6^10. Therefore, the expression simplifies to 6^10 / 6^10, which is equal to 1. So the value of the expression is 1.

Brian works 24 hours this week. His earns 9.25 per hour. He pays $37.50 in payroll tax. He deposits half of his pay after taxes in his savings account. He deposits the other half of his pay after taxes in his checking account. How much money is deposited into each account?​

Answers

Answer:

$92.25

Step-by-step explanation:

Begin with 24 hours times $9.25 an hour.

Get $222.

Subtract $37.50.

Get $184.5.

Divide this by 2.

Get $92.25 as your final answer

Brian will deposit $92.25 into both his savings account and his checking account after calculating his net pay by subtracting payroll taxes from his gross earnings and dividing the remainder by two.

To calculate how much money is deposited into Brian's savings and checking accounts, we need to follow these steps:

First, calculate Brian's gross pay by multiplying his hourly wage by the number of hours he worked.Deduct the payroll taxes from the gross pay to find out the net pay.Divide the net pay by two to determine how much goes into each account.

Let's do the math:

Brian's gross pay = 24 hours x $9.25/hour = $222Brian's net pay after taxes = $222 - $37.50 = $184.50Money deposited into each account = $184.50 / 2 = $92.25

So, Brian will deposit $92.25 into his savings account and another $92.25 into his checking account.

The $120 repair bill included $36 for parts and rest for labor. What percent of the bill was for labor?​

Answers

Answer:

30%

Step-by-step explanation:

Final answer:

70% of the $120 repair bill was for labor, calculated by subtracting the cost of parts from the total bill and then finding the percentage of the remaining labor cost.

Explanation:

The question is asking what percent of a $120 repair bill was for labor if $36 was for parts. Since the total bill is $120, the cost for labor is the total bill minus the cost for parts, which is $120 - $36 = $84 for labor. Now, to find the percentage of the bill that was for labor, you use the formula (part/whole) × 100, which in this case is ($84/$120) × 100 = 70%. Therefore, 70 percent of the bill was for labor.

Carlos bought 6 1/2 pounds of bananas for 5.20. What quantity of bananas would one dollar buy? You answer should be in the form _ _._ bananas Write your answer as a mixed number in decimal form. _ _ ._

Answers

Answer:

$1 would buy 1.25lbs of bananas

Step-by-step explanation:

In order to find the amount $1 will buy, we need to create a proportion. One the left side we can use the unit rate. On the right we use the unknown quantity.

6.5lbs/$5.20 = xlbs/$1.00

Now we cross multiply

6.5 * 1.00 = 5.20 * x

6.5 = 5.20x

1.25 = x

Final answer:

Carlos can buy approximately 4.17 bananas with one dollar.

Explanation:

To find out how many bananas one dollar can buy, we need to divide the total cost of the 6 1/2 pounds of bananas by the total cost of the bananas Carlos bought. $5.20 / 6 1/2 = $0.80 per pound. To find the quantity of bananas one dollar can buy, we divide $1.00 by $0.80 per pound. $1.00 / $0.80 = 1.25 pounds. Since there are 2 pounds in 1 kilogram and 0.5 kilograms is equal to 1 pound, we can convert the 1.25 pounds to kilograms. 1.25 pounds * 0.5 kilograms/pound = 0.625 kilograms. Finally, assuming each banana weighs approximately 0.15 kilograms, we can calculate how many bananas one dollar can buy. 0.625 kilograms / 0.15 kilograms/banana = 4.167 bananas.

To convert liters to milliliters, multiply the number of liters by 1000. Therefore, 627 liters is equal to 627,000 milliliters.

Explanation:

To correctly complete the statement 627 L = ? mL, we need to convert liters to milliliters. Since there are 1000 milliliters (mL) in 1 liter, we multiply the number of liters by 1000 to find the number in milliliters.

Thus, the conversion is:

627 L × 1000 = 627,000 mL

Therefore, the statement 627 L = 627,000 mL is correct.

The Johnson family drove 52 miles on 4 gallons of gasoline. Which of the following equations can be used to find how far they can travel on a full tank of 15 gallons?

Answers

Answer:

y = 13x

Step-by-step explanation:

First we need to take the number miles the Johnson family drove and divide it to the number of gallons of gasoline used to find how many miles per gallon

Miles per gallon = 52/4

Miles per gallon = 13

Now that we know how many miles per gallon, let's make an equation to find how much they can travel on a full tank of 15 gallons.

Let y = number of miles traveled

Let x = number of gallons

y = 13x

Now let's see how much they can travel in 15 gallons.

y = 13x

y = 13(15)

y = 195 miles

So the Johnson family can drive 195 miles on a full tank of 15 gallons of gasoline.

In this case;

b = 4 , a = 1

Therefore;

x = -4/2(1)

  = -2

Thus; the axis of symmetry is x = -2

Answer:

x = -2 is the axis of symmetry.

Step-by-step explanation:

We have given the function:

f(x)=x²+4x-19

We have to find the axis of symmetry.

We know that the formula for axis of symmetry is:

x = -b /2a
