a wheelchair ramp has a slope of 1/10.if its rise is 5 1/2 feet,what is its run?
slope = rise/run
1/10 = (11/2)/run
cross-multiply
run = (10)(11/2) = 110/2 = 55 feet
thnx
To find the run of the wheelchair ramp, we can use the formula:
Slope = Rise / Run
Given that the slope of the wheelchair ramp is 1/10 (or 1:10) and the rise is 5 1/2 feet, we can substitute these values into the formula:
1/10 = 5 1/2 / Run
To solve for the run, we need to isolate the variable. First, let's convert the mixed number (5 1/2) to an improper fraction:
5 1/2 = (5 * 2 + 1) / 2 = 11/2
Now, we can rewrite the equation:
1/10 = 11/2 / Run
To get rid of the fraction, we can cross-multiply:
1 * Run = 10 * (11/2)
Run = (10 * 11)/2
Run = 110/2
Run = 55
Therefore, the run of the wheelchair ramp is 55 feet.
