Question

The grade of a rod is its slope error as a percent find the grade of the road shown

Answer 1

The slope of the line is given by:

`\begin{gathered} \text{Slope}=\tan ((3)/(12))=4.363350821*10^(-3) \\ \text{Slope}=0.436335\text{ percent} \end{gathered}`

So the slope in percent is 0.436355% which can be rounded to 0.44%.
