Answer:
C) about 113
Step-by-step explanation:
"How many people are there per square mile?" means that we want a ratio with miles as denominator. In other words, to find the population density, we just need to divide the population by the land area (miles squared):
[tex]population-density=\frac{people}{land-area}[/tex]
We know that the population of Alabama is 90,000 people and its land area is 800 miles squared, so [tex]people=90000[/tex] and [tex]land-area=800mi^{2}[/tex].
Replacing values:
[tex]population-density=\frac{people}{land-area}[/tex]
[tex]population-density=\frac{90000}{800mi^{2}}[/tex]
[tex]population-density=112.5[/tex]
Which rounds to:
[tex]population-density=113[/tex]
We can conclude that there are approximately 113 people per square mile in Alabama.
