Chapter 8.4, Problem 7E

To determine

To find:

The slope of wakeboard. Compare this slope with the slope of the ramp is example 1.

Answer to Problem 7E

The slope of the waker-board ramp would be $\frac{5}{12}$ .

Explanation of Solution

Given:

A wakeboard ramp has a rise of 5 feet and a run of 12 feet.

Calculation:

We know that the slope of a line is equal to rise over run.

  $\text{Slope}=\frac{\text{Rise}}{\text{Run}}$

Upon substituting our given values in slope formula, we will get:

  $\text{Slope}=\frac{\text{Rise}}{\text{Run}}=\frac{5}{12}$

Therefore, theslope of the waker-board ramp would be $\frac{5}{12}$ .

The slope of the waker-board given in example 1 is $\frac{3}{5}$ .

Let us compare both slopes by making a common denominator as:

  $\frac{5}{12}=\frac{25}{60}$

  $\frac{3}{5}=\frac{36}{60}$

Since 36 is greater than 25, therefore, the slope of waker-board in example (1) is greater.
