Solve Some Algebra Problems Using The Properties Of Equality...pls Help Im Horrifyingly Bad A Math I

Answers

Answer 1

Answer:

a. Property 1

b. Property 2

Step-by-step explanation:

In this case, what we will do is say the properties of the equations, which are 4, the following:

Property 1: When a number is added or subtracted to both sides of equality, equality remains.

Property 2: When multiplied or divided by the same number, other than zero, on both sides of equality, equality remains.

Property 3: When both members of equality are raised to a nonzero power, equality remains.

Property 4: When the same root is extracted, on both sides of the equality, equality remains.

In other words, property 1 is used in part a and property 2 is used in part b.

Brandon estimates that he will need $18,000 each year to attend a 4-year college. His family can pay $5,000 a year. And he can get a student loan for $10,000 each year. If he saves $250 a month, how many months will it take him to save the rest of the money he will need for college?

Answers

Answer:

48 months

Step-by-step explanation:

Brandon estimates that he will need $18,000 each year to attend a 4-year college.

His family can pay $5,000 a year and he can get a student loan for $10,000 each year.

This means that, each year, $15000 out of the $18000 has been covered. That is the sum of the money from his parents and the loan:

$5000 + $1000 = $15000

That means the amount he still needs to cover per year is:

$18000 - $15000 = $3000

In 4 years, he will need to cover:

4 * $3000 = $12000

He saves $250 a month. Therefore, the number of months he will need to save $12000 is:

[tex]\frac{12000}{250} = 48 months[/tex]

He will need to save for 48 months to save the rest of the money he will need for College.

Answer: It will take him 48 months.

Step-by-step explanation:

Hi, to answer this question we have to write an equation:

the amount his family can pay per year (5000) multiplied by 4 (since is a 4 year college) ; plus the amount of the loan he gets per year (1000) also multiplied by 4 ; plus the amount he saves per month (250) multiplied by the number of months (m) must be equal to the amount he will need per year for college (18000) multiplied by 4.

Mathematically speaking

18000 x 4 = (5000 x 4) + (10000x 4) + 250 m

Solving for m

72000= 20,000+ 40,000+ 250m

72,000-20,000-40,000 = 250m

12,000= 250m

12,000/250 = m

48 =m

A greengrocers sells mangoes for 77p each.

a)

Find the greatest number of mangoes you can buy for £5.

b) How much change should you receive?

Answers

Answer:

6 mangoes

0.38 or 38p

Step-by-step explanation:

Apparently the value of the mango is £ 0.77, which means that to get the number of mangoes you can buy, you must divide this value to the amount of money you have, that is, £ 5

5 / 0.77 = 6.49

which means that it is enough for 6 mangoes.

To know the change, multiply the value of one by 6 and subtract it with £ 5, it would be the change.

6 * 0.77 = 4.62

5 - 4.62 = 0.38

That is, the change is £ 0.38 or 38p

Answer:

(a) 6 mangoes

(b) £0.38

Step-by-step explanation:

(a) The greengocers sell the mangoes for 77 p.

The greatest number of mangoes you can buy for £5 can be gotten by dividing £5 by the price of each mango (77 p). We will only pick the whole number part because number of mangoes can only be whole number.

First, we convert £5 to pence:

£1 = 100 pence

=> £5 = 5 * 100 = 500 pence

Hence, the greatest number of mangoes that can be bought is:

500 / 77 = 6.49

Since we are only picking the whole number part, the answer is 6 mangoes.

(b) The price of 6 mangoes is:

6 * 77 = 462 pence

Hence, if you take £5 (500 pence) to the store, your change should be:

500 - 462 = 38 pence

38 pence is the same as £0.38

Final answer:

Synthetic division is a process used to divide a polynomial by a linear expression. Using a step-by-step process, the polynomial 3x^3 - 2x^2 - 7x + 6 is divided by x + 1. The result is a new polynomial, which represents the quotient and a remainder.

Explanation:

Synthetic division is used to divide a polynomial by a linear expression. In this case, we have the polynomial (3x^3 - 2x^2 - 7x + 6) and we want to divide it by (x + 1). Synthetic division follows a specific set of steps:

Write the coefficients of the polynomial in a row: 3, -2, -7, 6. Write the root of the divisor, which is the solution to x + 1 = 0. This root is -1. Drop down the leading coefficient, which is 3 in this case. Multiply the root by the number just brought down, and write the result under the next coefficient. So, (-1)*3 = -3. Add the numbers in that column to get the next number to bring down. (-2) + (-3) = -5. Repeat steps 4 and 5 until all coefficients have been processed.

The numbers at the bottom are the coefficients of the quotient polynomial, and the remainder if any.

On some other planet, Thor stands on a bridge and throws his hammer at his brother Loki, who is at ground level. The hammer’s height h (in meters above the ground), t seconds after Thor threw it, is modeled by:

Answers

Answer:

h(0) = 3600

t=60 when it hits the ground

max height at 4050

at 15 seconds

Step-by-step explanation:

h(t) = -2t^2 + 60t +3600

When it is thrown is t=0

h(0) = -2(0) +60(0) +3600 = 3600

When it hits the ground is h(t) =0

0 =  -2t^2 + 60t +3600

Factor out -2

0 = -2 (t^2 -30t -1800)

Divide by -2

0 = (t^2 -30t -1800)

Factor.  What 2 numbers multiply to -1800 and add to -30

0 = (t+30) (t-60)

Using the zero product property

t+30 = 0   t-60 =0

t = -30     t = 60

Since we do not have negative time

t=60

The maximum occurs halfway between the zeros

(-30+60)/2 = 30/2 = 15

Put this into the function to find the maximum value

h(15) = -2(15)^2 + 60(15) +3600

       = -2 (225) +900+3600

       =4050

Answer:

Thrown at: 3600

Ground after: 60

Max height: 4050

After: 15

Step-by-step explanation:

h(t) = -2t² + 60t + 3600

h(0) = 3600

-2t² + 60t + 3600 = 0

t² - 30t - 1800 = 0

t² - 60t + 30t - 1800 = 0

t(t - 60) + 30(t - 60) = 0

(t - 60)(t + 30) = 0

t = 60, -30(not possible)

h(t) = -2t² + 60t + 3600

-2(t² - 30t) + 3600

-2(t² - 2(t)(15) + 15² - 15²) + 3600

A sociologists was investigating the ages of grandparents of high school students. From a random sample of 10high school students, the sociologist collected data on the current ages, in years, of the students' maternal grandparents. A. One of the sociologist's research questions was about the mean difference in age without regard to which grandparent is older. The interval constructed in part (a) does not address such a question. Based on the sample of high school students, give the value of the point estimate for the mean difference in age that could be used to address the sociologist's question.

Answers

Answer:

The answer for (a)(-5.96, 2.36) (b) -1.8, since the difference is negative, it can be said or determined that the age of the grandfather is older

Step-by-step explanation:

Solution

(a) From the information given,

n = 10, d =-1.8, sd = 5.81

The 95% confidence interval  for the population  mean difference age is computed as follows:

CI =d ±tα/2,n-1 (sd/√n)

= -1.8±t₀.₀₅/₂,₁₀₋₁ (5.81/√10)

=-1.8± 2.26 (1.84)

= -1.8 ± 4.16

= (-5.96, 2.36)

Now,

There is a 95% confidence  that the mean difference in age of maternal grand parents of high school students lies between - 5.96 and 2.36

(b) The age difference is calculated  as the age of grand mother minus age of grand father. the point of estimate for the mean difference is as follows:

Xd = XGM - XGF

= 69.8 -71.6

=-1.8

Therefore, since the difference is negative, it can be said or determined that the age of the grandfather is older

Note: kindly find an attached copy of the complete question and table to this example below.

Final answer:

The mean difference in age between grandparents is calculated by taking the absolute differences between the ages of each pair of grandparents from the sample of students and then averaging those differences.

Explanation:

The sociologist's research question about the mean difference in age of grandparents without regard to which one is older requires calculating the absolute difference between the ages of each pair of maternal grandparents for the sample of high school students and then taking the average of those differences. To provide a point estimate for the mean difference in age to address the sociologist's question, let us assume we have the ages of each pair of grandparents for the 10 students. If we denote these age pairs as (G11, G21), (G12, G22), ..., (G110, G210), where G1 and G2 are the ages of the two grandparents for each student, the mean difference in age would be the sum of the absolute differences of these pairs divided by the number of pairs (10 in this case).

Mean Difference = (|G11 - G21| + |G12 - G22| + ... + |G110 - G210|) / 10

Without the actual data, we cannot provide a numerical point estimate, but this is the method that would be used to calculate it.

Subtract the second equation from the first equation. Substitute the value of x from one equation into the other equation.

Answers

Answer:

B

Step-by-step explanation:

Our system of equations is:

3x + y = 23

8x + 2y = 23

If we want to use substitution, that means that we essentially want to manipulate one of the two equations so that one variable (like y) is written in terms of the other (like x), and then substitute that expression into the second equation so that we have one variable and one equation and we can easily solve from there.

So the first thing to be done is to write one of the variables in terms of the other. It would be easiest to do it with the first equation and write y in terms of x - in other words, "solve the first equation for y".

The answer is B.

the exam.
What percentage of exam scores are lower than Calvin's score?
a) 61.79%
b) 65.17%
c) 34.83%
d) 38.21%

Answers

Answer:

The percentage of people that scored less than Calvin is 38.21 %

Step-by-step explanation:

In this question, we are concerned with calculating the percentage of exam scores lesser than what Calvin scores.

To calculate this, we first need to calculate the standard score or the z-score of Calvin result.

Mathematically;

z = (x - mean)/SD

from the question, x = 78, mean = 81 and SD = 10

Substituting this, we have

z = (78 -81)/10 = -3/10 = -0.3

So we proceed to calculate the probability.

P(x < 78) or P(z < -0.3)

We make use of the standard table to get this probability

P(z< - 0.3) = 0.38209

In percentage, this is same as 38.209% or more simply 38.21%

On a recent trip to the convenience store, you picked up 4 gallons of milk, 6 bottles of water and 5 snack size bags of chips. You total bill before tax was $ 27.2. If a bottle of water costs twice as much as a bag of chips, and a gallon of milk costs $1.80 more than a bottle of water, how much does each item cost

How much does a snack size bag of chips cost?


How much does a bottle of water cost?


How much does a gallon of milk cost?

Answers

Answer:

Cost of a snack size bag of chips = $0.8

Cost of a water bottle = $1.6

Cost of a gallon of milk = $3.4

Step-by-step explanation:

Let the cost of water bottle = $a

Cost of 1 gallon milk = $b

and cost of 1 bag of chips = $c

So, cost of 4 gallons of milk, 6 bottles of water and 5 bags of chips = $(4b + 6a + 5c)

4b + 6a + 5c = 27.2 -----(1)

Cost of one water bottle = 2 × cost of one bag of chips

a = 2c -----(2)

A gallon of milk = cost of water bottle + $1.80

b = a + 1.8

From equation (2)

b = 2c + 1.8 -----(3)

Now we substitute these values from equations (2) and (3) in equation (1)

4(2c + 1.8) + 6(2c) + 5c = 27.2

8c + 7.2 + 12c + 5c = 27.2

25c = 27.2 - 7.2

c = [tex]\frac{20}{25}[/tex]

c = $0.8

From equation (2)

a = 2×0.8

a = $1.6

From equation (3)

b = 2(0.8) + 1.8

b = 1.6 + 1.8

b = $3.4

Therefore, cost of a snack size bag of chips = $0.8

Cost of a water bottle = $1.6

Cost of a gallon of milk = $3.4

Final answer:

A snack size bag of chips costs $0.80, a bottle of water costs $1.60, and a gallon of milk costs $3.40. This was determined by creating an equation with the given cost relationships and solving for the cost of each item.

Explanation:

The question presents a scenario where a trip to the convenience store involves purchasing 4 gallons of milk, 6 bottles of water, and 5 snack size bags of chips with a total bill of $27.20 before tax. The cost relationships given are: a bottle of water costs twice as much as a bag of chips, and a gallon of milk costs $1.80 more than a bottle of water.

Let's denote the cost of a snack size bag of chips as c. Thus, the cost of a bottle of water would be 2c. A gallon of milk would then cost 2c + $1.80.

To find the cost of each item, we can set up an equation based on the total cost:

5c + 6(2c) + 4(2c + $1.80) = $27.20

Solving this equation:

5c + 12c + 8c + $7.20 = $27.20

25c + $7.20 = $27.20

25c = $20

c = $0.80

Therefore, a snack size bag of chips costs $0.80, a bottle of water costs $1.60, and a gallon of milk costs $3.40.

When we divide a number ( whether fraction or not ) by a fraction, then we first change the operator to multiplication and  reciprocate the second fraction.

Let's take an example:

Suppose we have h division problem in fraction as [tex]\dfrac{2}{3}\div\dfrac{4}{9}[/tex]

Then, our first step would be to change division operator (÷) by multiplication operator (×) and then ×reciprocate the second fraction , so the next step will become [tex]\dfrac{2}{3}\times\dfrac{9}{4}[/tex] , Now cancel out 3 and 2 from both numerator and denominator , we get

[tex]\dfrac{1}{1}\times\dfrac{3}{2}=\dfrac{3}{2}[/tex]

i.e. [tex]\dfrac{2}{3}\div\dfrac{4}{9}=\dfrac{3}{2}[/tex]

Hence, the correct option is "D. Dividing".

The first step which involves changing the operator to multiplication of the reciprocal of the second fraction is when dividing.

It is an expression, as an equation has an equal sign on it.

This has no equality property, therefore it is an expression.

Expression because an equation would have an = sign

what is consecutive whole numbers? I have to write an algebraic expression for the sum of three consecutive whole numbers... :(

Answers

Answer:

Consecutive whole numbers (or integers) are numbers that directly follow one another.

Eg: 1, 2, 3, 4, 5 are consecutive whole numbers.

Step-by-step explanation:

Three consecutive even integers can be represented by x, x+2, x+4. The sum is 3x+6, which is equal to 108.

or

let the three consecutive whole numbers is x, x+1,and x+2

x + x+1 + x+2 = 4+2(x+1)

3x+3=4+2x+2

3x-2x=6-3

x=3

the other two numbers are 3+1=4,and 3+2=5

so the three numbers are 3,4 and 5

Find the value of csc theta, if cos =-3/5; 90 degrees < theta < 180 degrees

Answers

Answer:[tex]\frac{5}{4}[/tex]

Step-by-step explanation:

Given

[tex]\cos \theta =\frac{-3}{5}[/tex]

and [tex]\theta [/tex]  lies between

[tex]90^{\circ}<\theta <180^{\circ}[/tex]

and for this [tex]\theta[/tex],[tex]\sin[/tex] and [tex]\text{cosec}[/tex] is Positive as they lie in 2 nd Quadrant

[tex]\sin ^2\theta +\cos ^2\theta =1[/tex]

[tex]\sin ^2\theta =1-(\frac{-3}{5})^2[/tex]

[tex]\sin ^2\theta =1-\frac{9}{25}[/tex]

[tex]\sin ^2\theta =\frac{16}{25}[/tex]

[tex]\sin \theta =\frac{4}{5}[/tex]

[tex]\therefore \text{cosec}\ \theta =\frac{5}{4}[/tex]
