The inclined plane below is being used to lift a box 7 ft. The inclined plane has a mechanical advantage of 1.5. What is the length, x, of the inclined plane? mechanical advantage = (length of ramp)/(height of ramp) a 7.5 feet b .25 feet c 10.5 feet d 2.5 feet

1 answer

The formula for mechanical advantage is:
mechanical advantage = (length of ramp)/(height of ramp)

We are given that the mechanical advantage is 1.5 and that the height of the ramp is 7 ft. Let's substitute these values into the formula:

1.5 = (length of ramp)/7

To solve for the length of the ramp, we need to isolate it on one side of the equation. We can do this by multiplying both sides of the equation by 7:

1.5 * 7 = length of ramp
10.5 = length of ramp

Therefore, the length, x, of the inclined plane is 10.5 ft.

So the correct answer is c) 10.5 feet.
