Question

A set of stairs is to be built so that each step has a vertical rise of 20 cm over a horizontal run of 27.5 cm. Find the slope, to the nearest hundredth.

a. 0.73
b. 1.38
c. 0.73 cm
d. 1.38 cm

Answer 1

The slope of the stairs is approximately 0.73 cm.

Step-by-step explanation:

The slope of a set of stairs can be found by dividing the vertical rise (height) of each step by the horizontal run (width). In this case, the vertical rise is 20 cm and the horizontal run is 27.5 cm. Using the formula for slope, we have:

Slope = vertical rise / horizontal run = 20 cm / 27.5 cm = 0.73

Therefore, the slope is approximately 0.73 cm.
