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

Answer:

The value is  $m = 0.9022$

Step-by-step 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

         $m = \frac{b}{a}$

=>       $m = \frac{8.12}{9}$

=>       $m = 0.9022$
