Question

6 there are approximately 690 grizzly bears in yellowstone national park giving them a density of about .2 grizzlies per square mile. what is the approximate area of the park?

Explanation:

Step1: Recall density formula

Density = $\frac{\text{Number of bears}}{\text{Area}}$, so Area = $\frac{\text{Number of bears}}{\text{Density}}$.

Step2: Substitute values

We know number of bears = 690 and density = 0.2. So Area = $\frac{690}{0.2}$.

Step3: Calculate result

$\frac{690}{0.2}=3450$ square - miles.

Answer:

3450 square miles
