Answer:
Customer have to drive for 100 miles for the cost to be $140.
Step-by-step explanation:
Here, the cost of rest function is given as:
C = 120+.20 m
From above function, we can see that :
m = Number of miles traveled by the rent car
(1) The fixed rental charge of renting a car = $120
(2) The per mile rent of the car = $0.20
Now, C = $140
⇒140 = 120+.20 m
or 140 - 120 = 0.20 m
or, 0.20 m = 20
⇒ m = 20/0.20 = 100
or, m = 100
Hence, customer have to drive for 100 miles for the cost to be $140.
For a triangular prism, the formula for volume is v=bh where b is the area of the base (72) and h is the height (20). 72x20=1440 so the volume is 1440 cm^3
As for surface area, you want to find the area of each of the faces. For the triangle faces the area is 72. For the three identical rectangle faces the area is 240. 240x3+72x2= 720+144=864cm^2
Hope this helped :)
