To convert 8.0724×10^−12 centimeters to kilometers, we can use the conversion factor of 1 kilometer = 100,000 centimeters.
First, we divide 8.0724 by 100,000 to convert it to kilometers:
8.0724 × 10^−12 / 100,000 = 8.0724 × 10^−17 kilometers.
The correct answer is:
8.0724×10^−17 kilometers.

To find the height of Mt. Everest, we add the height difference (9×10^3 ft) to the height of Denali (20,000 ft).
20,000 ft + 9×10^3 ft = 29,000 ft
Therefore, Mt. Everest is about 29,000 ft high.
The answer is expressed in decimal notation as 29,000 ft.
20,000 ft + 9×10^3 ft = 29,000 ft
Therefore, Mt. Everest is about 29,000 ft high.

To find the increase in the world's population, we subtract the population in 1500 CE from the population in 2020.
7.8×10^9 - 4.5×10^8 = 7.35×10^9
Therefore, the world's population increased by approximately 7.35×10^9.
7.8×10^9 - 4.5×10^8 = 7.35×10^9
Therefore, the world's population increased by approximately 7.35×10^9.

To find the difference in tons of paper and plastic recycled in 2010, we subtract the amount of plastic recycled from the amount of paper recycled:
4.6×10^7 tons - 2,600,000 tons = 4.34×10^7 tons
Therefore, 4.34×10^7 tons more paper was recycled than plastic in 2010.
4.6×10^7 tons - 2,600,000 tons = 4.34×10^7 tons
Therefore, 4.34×10^7 tons more paper was recycled than plastic in 2010.

To find the number of atoms in a cubic foot of sand, we multiply the number of grains of sand by the number of atoms in each grain of sand:
4×10^9 grains x 6×10^19 atoms = 24×10^28 atoms
Therefore, you would expect to find approximately 24×10^28 atoms in a cubic foot of sand.
4×10^9 grains x 6×10^19 atoms = 24×10^28 atoms
Therefore, you would expect to find approximately 24×10^28 atoms in a cubic foot of sand.

To find the number of pennies in the pile, we divide the total weight of the pile by the weight of a single penny:
3.596×10^4 lb / 5.8×10^−3 lb = 6.2×10^6 pennies
Therefore, there are approximately 6.2×10^6 pennies in the pile.
3.596×10^4 lb / 5.8×10^−3 lb = 6.2×10^6 pennies
Therefore, there are approximately 6.2×10^6 pennies in the pile.

To find the number of years it will take to yield $6.42×10^4, we divide the desired amount by the annual interest:
6.42×10^4 / $802.50 = 8×10^1 years
Therefore, it will take approximately 8×10^1 (80) years to yield $6.42×10^4.
6.42×10^4 / $802.50 = 8×10^1 years
Therefore, it will take approximately 8×10^1 (80) years to yield $6.42×10^4.
