Question

You’re on a residential construction team doing roofing. The pitch of a roof is 13 rise over run. Find the rise if the horizontal run of the roof is 15 feet 34 inches.

Answer 1

Answer:

5 feet 1/4 inches

Step-by-step explanation:

The pitch of the roof is the ratio of the rise to run of the rafters

Answer 2

Answer:

$231\ ft\ 10\ in$

Step-by-step explanation:

Let

y------> the rise

x------> the run

In this problem we have

$x=15\ ft\ 34\ in$

step 1

Convert feet to inches

we know that

$1\ feet=12\ inches$

so

$15\ ft\ 34\ in=15*12+34=214\ in$

step 2

Find the rise

$13=\frac{y}{x}$

substitute the value of x and solve for y

$13=\frac{y}{214}$

$y=13*214=2,782\ in$

Convert to feet

$2,782\ in=2,782/12=231.83\ ft=231\ ft\ 10\ in$
