Question:
Hawaii has an area of 1.1 × 10^4 square miles and a population of 1.2 × 10^6 people.
Which key strokes on a calculator will give the population density of Hawaii?
Answer:
The population denisty of Hawaii is 109.09 people per square mile
Solution:
Given that,
[tex]Area\ of\ Hawaii = 1.1 \times 10^{4} \text{ square miles }[/tex]
[tex]Population\ of\ hawaii = 1.2 \times 10^6 \text{ people }[/tex]
To find: Population density of Hawaii
To calculate the population density, you will divide the population by the size of the area
[tex]\text{Population density } = \frac{\text{Number of people}}{\text{ Land Area }}[/tex]
Substituting the given values, we get]
[tex]\text{Population density } = \frac{1.2 \times 10^6}{1.1 \times 10^4}[/tex]
Use the law of exponent,
[tex]\frac{a^m}{a^n} = a^{m-n}[/tex]
Applying this we get,
[tex]\text{Population density } = \frac{1.2 \times 10^{6-4}}{1.1 }\\\\\text{Population density } = \frac{1.2 \times 10^2}{1.1 }\\\\\text{Population density } = 1.09 \times 10^2 = 1.09 \times 100\\\\\text{Population density } = 109.09[/tex]
Thus the population denisty of Hawaii is 109.09 people per square mile
