Answer :
Answer:
The answer to your question: World's energy = 4.15 x 10 ¹⁶ BTU
Step-by-step explanation:
USA energy = 23.5%
BTU = 97.6 quatrillion = 97600000000000000
World's energy consumption = ?
1 quatrillion = 1 000 000 000 000 000
9760000000000000 --------------- 23.5%
x --------------- 100%
x = 100 x 9760000000000000 / 23.5
X = 4.15 x 10 ¹⁶ BTU
Final answer:
To find the world's energy consumption in 2002, we can set up a proportion using the United States' share. By solving this proportion, we find that the world's energy consumption was approximately 414.04 quadrillion British thermal units (Btu).
Explanation:
To determine the world's energy consumption in 2002, we can use the information given about the United States' share of energy consumption. If the United States accounted for 23.5% of the world's energy consumption and used 97.6 quadrillion Btu, we can set up a proportion to find the world's energy consumption. Let's call it 'W'.
23.5% of W = 97.6 quadrillion Btu
To solve this proportion, we can cross multiply:
23.5% * W = 97.6 quadrillion Btu
Then divide both sides of the equation by 23.5% to solve for W:
W = (97.6 quadrillion Btu) / (23.5%)
Now we can calculate W:
W ≈ 414.04 quadrillion Btu
