Question 117485: A roof rises 7.25 ft over a horizontal distance of 13.71 ft. What is the slope of the roof to the nearest hundredth? Answer by bucky(2189) (Show Source):
You can put this solution on YOUR website! The slope is defined as the vertical distance divided by the horizontal distance.
.
For this problem you are told that the vertical rise is 7.25 feet, and you are also told
that the horizontal distance over which this rise takes place is 13.71 feet. So for this
problem the slope is:
.
.
Using a calculator to divide 13.71 into 7.25 you get an answer of 0.528811086 and this slope rounds
off to the nearest hundredth as 0.53
.
The answer has no dimension associated with it. It is just a decimal value.
.
The answer you are looking for is just slope = 0.53
.
Hope this helps you to understand the problem.
.
And as added information, roofers and architects don't talk about what the decimal value
of a slope is. They generally talk in terms of how much the roof rises in a horizontal
distance of 12 inches. For this case the rise is .53 times 12 inches which is 6.36 inches.
So a roofer would say that the pitch (or slope) of the roof is 6.36 in 12.
