Question

question 7 (multiple choice worth 1 points) (06.03r mc) a county is in the shape of a rectangle that is 50 miles by 60 miles and has a population of 50,000. what is the average number of people living in each square mile of the county? round your answer to the nearest whole number.

Explanation:

Step1: Calculate county area

The area of a rectangle $A = l\times w$, where $l = 60$ miles and $w = 50$ miles. So $A=60\times50 = 3000$ square - miles.

Step2: Calculate population density

Population density $d=\frac{\text{Population}}{\text{Area}}$. The population is 50000. So $d=\frac{50000}{3000}=\frac{50}{3}\approx16.67$.

Step3: Round to nearest whole number

Rounding 16.67 to the nearest whole number gives 17.

Answer:

17
