A ramp is used to help a person in a wheel chair up some steps that are 75 cm high. The person and chair together weigh 800 N. The greatest force that the person can exert is 200 N. Find the minimum length of the inclined plane that is required.

i need points

step-by-step explanation:

sorry bubs

y = 3x+4

step-by-step explanation:

to find the slope

slope = (y2-y1)/ (x2-x1)

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4

the answer is 1030 it's very simple math.

step-by-step explanation:

let pq = qr = rs = x, and xz = y and zu = z.

if the horizontal lines are parallel, then corresponding segments are in proportion:

substitute:

therefore 3 = y = z.

xu = y + z → xu = 3 + 3 = 6
