MA= 8
There is no unit of measure.
I guess whoever ends up looking at this doesn't want to actually do their hw too. I am also guessing you got this question from your holt science& technology Physical Science Textbook. And that you are in 8th grade.
Increase the advantage.

It is 15/3 = 5
It should be like 25 feet long and put at a like 45 degrees angle
1 in 8 ramp means: for every 8 units horizontal, there will be a rise of 1 unit. Example: 8 feet of horizontal distance will slope upwards to a finish height of 1 foot. or 1 meter of horizontal distance will slope upwards to a finish height of 125 mm. In both examples height/horizontal length = 1/8 or 125/1000 = 1 in 8.
The height of the Great Pyramid = 139 metres The slope of a ramp with a mechanical advantage of 4 = 4x139 = 556m
The height of the Great Pyramid = 139 metres The slope of a ramp with a mechanical advantage of 4 = 4x139 = 556m
The height of the great pyramid = 139 metres The slope of a ramp with a mechanical advantage of 4 = 4x139 = 556m
Since the heights are the same, then the longer ramp.

There is a mechanical advantage in using a long, gently sloping ramp than a short steep ramp. If you want to test this remember what goes up must come down and a long ramp gives you more time to react
The mechanical advantage is 8/2 = 4.
The long ramp.
3.3 ft
You get mechanical advantage by the slope of the ramp. You move the object horizontally and raise the object slowly as you do so.
5J because 10/2=5
The maximun slope of an ADA ramp is 8.3% or 12:1.
