Fun Center rents popcorn machines for $20 per hour. In addition to the hourly charge, there is a rental fee of $32. Part A: Write an equation to represent the relationship between the number of hours (h) and the total cost (t).

NO SPACES - USE (h) and (t) - DO NOT CAPITALIZE

Part B: Fill in the data table in your notebook.

Part C: Type in h = hours and t = cost. - DO NOT CAPITALIZE

Identify the independent variable:

john earns $14.00 for two hours of work.

(b) 240

step-by-step explanation:

first, we use the pythagorean formula using the given side lengths to find x. then we use x to find the side lengths. then we add the side lengths to find the perimeter.

pythagorean theorem formula:

a^2 + b^2 = c^2

(x - 20)^2 + (x - 40)^2 = x^2

x^2 - 40x + 400 + x^2 - 80x + 1600 = x^2

x^2 -120x + 2000 = 0

(x - 100)(x - 20) = 0

x - 100 = 0 or x - 20 = 0

x = 100 or x = 20

we see that the solution x = 20 must be discarded because it will give a negative side length and a side length of 0. the only valid solution is x = 100.

perimeter = sum of the lengths of the sides

perimeter = x + x - 20 + x - 40

perimeter = 3x - 60

replace x with 100.

perimeter = 3(100) - 60

perimeter = 300 - 60

perimeter = 240
