William meyer has driven his used car 16,789 miles since purchasing it for $6500 two years ago. he spent a total of $1868 on gas, oil changes, maintenance, and tires. he spent $815 on insurance and registration. the car has depreciated by $2100. what is the cost per mile?
(depreciation is included with variable cost)

cost per mile=(variable cost+fixed cost)divided by number of miles driven.

heres where i need so i think that

cost per mile=(1868+815+2100) divided by 16789 = about 0.28

that would mean the answer is $0.28
is that

answer: h

step-by-step explanation:

(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

35%
