In a recent year, the population of California was about 2.52 x 107 people. Its land area is about 4.05 x 105 km2. What was the average number of people per square kilometer?
Well, let me calculate that for you! *puts on clownish math hat* To find the average number of people per square kilometer in California, we divide the population by the land area. So, 2.52 x 10^7 divided by 4.05 x 10^5 equals... *drumroll*... approximately 62.22 people per square kilometer! Looks like California sure knows how to pack 'em in! Just be careful not to trip over any surfboards on the crowded beaches! 🏄♂️🌊
To calculate the average number of people per square kilometer, we need to divide the population of California by its land area.
1. The population of California is given as 2.52 x 10^7 people.
2. The land area of California is given as 4.05 x 10^5 km^2.
Dividing the population by the land area gives us the average number of people per square kilometer:
(2.52 x 10^7) / (4.05 x 10^5)
To simplify this calculation, we can rewrite the numbers in scientific notation with the same exponent:
(2.52 / 4.05) x (10^7 / 10^5)
Simplifying further:
0.62 x 10^2
Finally, we convert this back into standard form:
0.62 x 100 = 62
Therefore, the average number of people per square kilometer in California is 62.
To calculate the average number of people per square kilometer in California, you need to divide the total population by the land area.
First, let's simplify the values given:
Population: 2.52 x 10^7 (This is in scientific notation. The exponent 7 represents the number of zeros after the 2.52.)
Land area: 4.05 x 10^5 (Again, the exponent 5 represents the number of zeros after 4.05.)
To calculate the average number of people per square kilometer, divide the population by the land area:
Average number of people per square kilometer = Population / Land area
Now substitute the values:
Average number of people per square kilometer = 2.52 x 10^7 / 4.05 x 10^5
To divide numbers in scientific notation, you can subtract the exponents:
Average number of people per square kilometer = (2.52 / 4.05) x 10^(7-5)
Simplifying further:
Average number of people per square kilometer = 0.62 x 10^2
Since 0.62 is less than 1, we can convert it to standard decimal notation. Multiply by 10^2 to move the decimal point two places to the right:
Average number of people per square kilometer = 62
Therefore, the average number of people per square kilometer in California is 62.
2.52*10^7 ppl / 4.05*10^5 km^2 = 2.52/4.05 * 10^(7-5)
= 0.622 * 10^2
= 62.2 ppl/km^2
