Find the slope of a pipe that slopes down 2/5 inch per foot.

Verdich [7]

Answer:

$m=\frac{1}{30}$

Step-by-step explanation:

we know that

To find out the slope divide the rise by the run to calculate the slope.

Remember that

1 ft=12 in

Let

y ----> the rise

x ----> the run

m ----> the slope

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

we have

$y=2/5\ in$

$x=1\ ft=12\ in$

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

substitute the values

$m=\frac{(2/5)}{12}$

$m=\frac{2}{60}$

Simplify

$m=\frac{1}{30}$
