The slope for a wheelchair ramp for a home has to be 1/2. if the vertical distance from the ground to the door bottom is 3 ft, find the distance the ramp has to extend from the home in order to comply with the needed slope. write your work in the answer box.

Respuesta :

Answer:

6 ft

Step-by-step explanation:

slope = [tex]\frac{rise}{run}[/tex] ( rise is vertical height and run is horizontal distance )

here vertical height = 3 and slope = [tex]\frac{1}{2}[/tex] , then

[tex]\frac{1}{2}[/tex] = [tex]\frac{3}{run}[/tex] ( cross- multiply )

run = 2 × 3 = 6 ft
