Question 88718
Slope is defined as the change in the vertical distance divided by the corresponding
change in the horizontal distance.  In this problem the change in the vertical distance is
+ 8.5 ft and the corresponding change in the horizontal distance is 18.02 ft.  So the slope
of the roof is:
.
{{{slope = 8.5/18.02}}}
.
and doing the division with a calculator gives you:
.
{{{slope = 0.471698113}}}
.
Rounding this to the nearest hundredth tells you to look at the third position to the right of
the decimal point. It is a 1. Since that is less than 5, you leave the second position 
to the right of the decimal point at the value it is. So the rounded answer is:
.
{{{x = 0.47}}}
.
Hope this helps you to understand the meaning of slope.
