Perform the following calculation for the image below to the right number of sig figs:
[(11.422-0.800) + (8.0 + 1.115)/0.0720] 1.33 x 10^-5

• A. 3.64×10^-3
• B. 3.639×10^-3
• C. 3.6×10^-3
• D. 3.60×10^-3

Answer: (A)

Verified step by step guidance

1. First, perform the subtraction inside the first set of parentheses: (11.422 - 0.800). Pay attention to the number of decimal places in each number to determine the correct number of significant figures for the result.
2. Next, perform the addition inside the second set of parentheses: (8.0 + 1.115). Again, consider the number of decimal places to ensure the result has the correct number of significant figures.
3. Divide the result of the addition by 0.0720. When dividing, the number of significant figures in the result should be based on the number with the fewest significant figures used in the division.
4. Add the result from the subtraction to the result from the division. The number of decimal places in the final result should match the number with the fewest decimal places from the numbers being added.
5. Finally, multiply the entire expression by 1.33 x 10^-5. The number of significant figures in the final answer should be determined by the number with the fewest significant figures in the multiplication.
