The Earth's surface that is covered by water is 3.6x10^10, compared to the amount if Earth's surface that is covered by land which is 1.8x10^8, approximately how many times greater is the amount of Earth's surface covered by water, compared to the surface cover by land? Write your answer in scientific notation.
To find the ratio between the surface covered by water and the surface covered by land, we divide the surface covered by water by the surface covered by land:
Ratio = (3.6x10^10) / (1.8x10^8)
To divide the numbers in scientific notation, we divide the coefficients (3.6 / 1.8) and subtract the exponents (10^10 / 10^8):
Ratio = 2 / 10^2 = 2x10^-2
Therefore, the amount of Earth's surface covered by water is approximately 2x10^-2 times greater than the surface covered by land.
Like many reforms of the era, temperance and prohibition was A. terribly misguided. OB. a hopeless cause. C. an outgrowth of socialism. D. an international movement.
The correct answer is D. an international movement.
To determine how many times greater the Earth's surface covered by water is compared to the surface covered by land, we can divide the two values.
The Earth's surface covered by water is 3.6x10^10, and the surface covered by land is 1.8x10^8.
So, the ratio can be calculated as follows:
Ratio = (Surface covered by water) / (Surface covered by land)
Ratio = (3.6x10^10) / (1.8x10^8)
To divide the two values, we subtract the exponents:
Ratio = (3.6 / 1.8) x (10^10 / 10^8)
Ratio = 2 x 10^2 (since 10^10 / 10^8 = 10^2)
In scientific notation, the answer is 2x10^2, which can also be written as 200.
Therefore, the Earth's surface covered by water is approximately 200 times greater than the surface covered by land.
