The Earth's surface that is covered by water is 3.6 * 10 ^ 10 compared to the amount of Earth's surface that is covered by land which is 1.8 * 10 ^ 8 proximately how many times greater is the amount of earth's surface covered by water compared to the surface covered by land
To find the ratio between the amount of Earth's surface covered by water and land, we need to divide the two values.
Ratio = Surface covered by water / Surface covered by land
Ratio = (3.6 * 10^10) / (1.8 * 10^8)
Ratio = 20 * (10^10) / (10^8) [since 3.6/1.8 is 2]
Ratio = 20 * (10^2) [since 10^10 / 10^8 is 10^2]
Ratio = 20 * 100 [since 10^2 is 100]
Ratio = 2000
Therefore, the amount of Earth's surface covered by water is approximately 2000 times greater than the surface covered by land.
What's the answer in scientific notation
The answer in scientific notation would be:
Ratio = 2.0 * 10^3
A factory produces 2.3 * 10 ^ 5 will be produced after 200 hours?
This is a multiplication question
A. 4.3 * 10 ^ 5 marbles
B. 4.6 * 10 ^ 7 marbles
C. 223 * 10 ^ 5
D. 200 marbles
To find the total number of marbles produced after 200 hours, we need to multiply the production rate per hour by the number of hours.
Production = 2.3 * 10^5
Time = 200 hours
Total = Production * Time
Total = (2.3 * 10^5) * 200
Total = 4.6 * 10^7
The correct answer is B. 4.6 * 10^7 marbles.
national Park covers an area of 1.24 * 10 ^ 6 acres and nearby national Forest covers an area of 2.1 * 10 ^ 6 acres what is the total number of acres in the park and the forest together write your answer and scientific notation
To find the total number of acres in the park and the forest together, we need to add the two values.
Park area = 1.24 * 10^6 acres
Forest area = 2.1 * 10^6 acres
Total area = Park area + Forest area
Total area = (1.24 * 10^6) + (2.1 * 10^6)
Total area = 3.34 * 10^6 acres
Therefore, the total number of acres in the park and the forest together is 3.34 * 10^6 acres.
The approximate total surface area of Earth is 5.1 * 10 ^ 8 km2. all the salt water on Earth has approximate surface area of 352,000,000 km2. Freshwater on Earth has approximate surface area of 9 * 10 ^ 6 km2
how much of earth's surface is covered by water including both salt and fresh water write your answer in scientific notation
To find the total surface area of Earth covered by water, we need to add the surface areas of salt water and freshwater.
Surface area of salt water = 352,000,000 km^2
Surface area of freshwater = 9 * 10^6 km^2
Total surface area covered by water = Surface area of salt water + Surface area of freshwater
Total surface area covered by water = (352,000,000) + (9 * 10^6) km^2
Total surface area covered by water = 3.52 * 10^8 km^2 + 9 * 10^6 km^2
Total surface area covered by water = (3.52 + 0.009) * 10^8 km^2
Total surface area covered by water = 3.529 * 10^8 km^2
Therefore, the approximate total surface area of Earth covered by water, including both salt and fresh water, is 3.529 * 10^8 km^2.
