I have no idea what I am doing. Here is one of my problems, A gas station sells 1500 gallons of gasoline per hour if it charges $ 2.10 per gallon but only 1300 gallons per hour if it charges $ 2.95 per gallon. Assuming a linear model

(a) How many gallons would be sold per hour of the price is $ 2.70 per gallon?
(b) What must the gasoline price be in order to sell 800 gallons per hour?
(c) Compute the revenue taken at the four prices mentioned in this problem -- $ 2.10, $ 2.70, $ 2.95 and your answer to part (b). Which price gives the most revenue?

Answers

You need to set up a linear graph. One side with gallons and the other with dollars. Point 1 will be at (1500, 2.10). Point 2 (1300, 2.95). Draw a straight line through these points in your graph and your graph will then give you the answers to your other questions.

What is the first step in using the square root property?

Answers

Answer: Isolate the term that contains the squared variable. Then, take the square root of both sides and solve.

Step-by-step explanation:

To solve an equation by using the square root property, you will first isolate the term that contains the squared variable. You can then take the square root of both sides and solve for the variable. Make sure to write the final answer in simplified form.

A living room is two times as long and one and one-half times as wide as a bedroom. The amount ofcarpet needed for the living room is how many times greater than the amount of carpet needed for the
bedroom?
1 1/2
2
3
3 1/2

Answers

Answer:

3

Step-by-step explanation:

let's call X the length of the bedroom, Y the wide of the bedroom, A the length of the living room and B the wide of the living room

A living room is two times as long as the bedroom, so:

A = 2X

A living room is one and one-half times as wide as a bedroom, so:

B = 1.5Y

The amount of carpet needed for the living room is A*B and the amount of carpet needed by the bedroom is X*Y

So, AB in terms of XY is:

A*B = (2X)*(1.5Y) = 3(X*Y)

It means that the amount of carpet needed for the living room is 3 times greater than the amount of carpet needed for the  bedroom.

If you deposit $1,500 at a rate of 5%, in how many years would you earn $375 in interest?

Answers

Answer: it will take 5 years.

Step-by-step explanation:

Assuming it is simple interest, we would apply the formula for determining simple interest is expressed as

I = PRT/100

Where

I represents interest paid on the amount of money deposited.

P represents the principal or amount of money deposited.

R represents interest rate on the deposit.

T represents the duration of the deposit in years.

From the information given,

P = $1500

I = $375

R = 5%

Therefore,

375 = (1500 × 5 × T)/100

375 = 75T

T = 375/75

T = 5 years

Which is the equation of the line that has a slope of 1/2​
