The roof of a barn rises vertically 2.5 meters through the horizontal distance of 10 meters. What is the pitch (slope) of the ro

Lesechka [4]

Answer:

The pitch (slope) of the roof is $0.25$ or $25\%$

Step-by-step explanation:

we know that

The formula to calculate the slope is equal to

$m=\frac{y2-y1}{x2-x1}$

where

In this problem we have

${y2-y1}=2.5\ m$ -----> is the vertical distance (rises)

${x2-x1}=10\ m$ -----> is the horizontal distance (run)

substitute the values

$m=\frac{2.5}{10}=0.25$

convert to percentage form

$0.25*100=25\%$
