Question

According to the article, there are 3,000 brown tree snakes in Guam per square mile (mi2). The average high school in the United States is approximately 121,000 square feet or 0.004 square miles. According to these numbers, how many brown tree snakes would be found in an area the size of a typical U.S. high school?​

Answer 1

Answer:

12 snakes

Explanation:

Given

$3000\ snakes = 1\ mi^2$

Required

Determine  the number of snakes in 0.004mi²

Represent this with x;

So, we have:

$3000\ snakes = 1\ mi^2$

$x = 0.004\ mi^2$

Cross Multiply

$x * 1\ mi^2 = 3000\ snakes * 0.004mi^2$

$x * 1 = 3000\ snakes * 0.004$

$x = 3000\ snakes * 0.004$

$x = 12\ snakes$
