Question

Most staircases in use today have 9−inch treads and 8 12 −inch risers. What is the slope of a staircase with these measurements? Give your answer as a fraction or rounded to four decimal places, if necessary

Answer 1

The value is
`m = 0.9022`

Explanation:

From the question we are told that

The length of the treads is
`a = 9 \ inch`

The length of the risers is
`b = 8.12 \ inch`

Generally the slope of the staircase is

`m = (b)/(a)`

=>
`m = (8.12)/(9)`

=>
`m = 0.9022`
