d) 26.3

Answer 1

The answer to 32.5 x 0.81 with appropriate significant figures is 26.3.

Step-by-step explanation:

The answer to the calculation 32.5 x 0.81 should be reported with the appropriate number of significant figures. To determine the number of significant figures, count the number of digits in the number with the fewest significant figures. In this case, 0.81 has two significant figures. To report the answer with the proper number of significant figures, round the product of 32.5 and 0.81 to two significant figures.

32.5 * 0.81 = 26.3

So, the correct answer is 26.3 (Option d).
