The product of 24m and 3.26m is 78.24m². Since both values have two significant figures, the answer should be rounded to two significant figures as well, giving 78m².
To determine the correct number of significant figures in a calculation involving both addition and multiplication, follow these steps: Perform the addition or subtraction operation first, and count the number of decimal places in the result. For multiplication or division, count the number of significant figures in each number being multiplied or divided. The final answer should have the same number of significant figures as the number with the least number of significant figures in the calculation.
The calculation of 28.79 divided by 128.32 results in 0.2234.
In this sense, "reported to work" is correct. It's just an awkward sentence. You could change he first option to "reporting for work" and that would also be correct, but the position of the preposition is incorrect.
Rounding after each step in a calculation helps prevent errors from accumulating. It ensures that the final result is based on the correct number of significant figures and maintains accuracy throughout the process. This practice helps improve the precision of the calculated result.
To determine the correct number of significant figures in the final answer for the calculation (67.31 - 8.6 + 212.198), you first perform the subtraction and addition operations. The result of the subtraction (67.31 - 8.6) is 58.71, which has four significant figures. Adding 212.198 to 58.71 yields 270.908, which also has four significant figures. Therefore, the final answer should be rounded to four significant figures: 270.9.
