a wheelchair ramp has a slope of 1/10.if its rise is 5 1/2 feet,what is its run.
> a wheelchair ramp has a slope of 1/10
means that it rises 1 foot (rise) over a horizontal distance (run) of 10 feet.
Slopes are measured by the ratio rise/run.
For example, a rampe of 1/17, which is ususally the maximum preferred slope to enable manual wheelchairs to climb, with a rise of 2 ft will need a horizontal distance of 2*17=34 ft.
I'm sure you can take it from here.
To find the run of the wheelchair ramp, we need to use the given slope and rise.
The slope of a ramp is equal to the rise divided by the run. In this case, we are given the slope as 1/10 and the rise as 5 1/2 feet.
Let's first convert the mixed number 5 1/2 to an improper fraction.
5 1/2 = (2 * 5 + 1) / 2 = 11/2
Now we can set up an equation using the slope formula:
1/10 = (rise) / (run)
Replacing the rise with the converted improper fraction:
1/10 = (11/2) / (run)
To solve for the run, we can cross multiply:
10 * (11/2) = 1 * run
55/2 = run
Now let's simplify the fraction:
run = 55/2, which can also be written as 27 1/2 feet.
Therefore, the run of the wheelchair ramp is 27 1/2 feet.
