select the correct answer. what is the solution to the problem expressed to the correct number of significant figures? 15.11+(142×16.5)=? a. 2,358 b. 2,358.1 c. 2,360 d. 2,400

Answer

Explanation:

Step1: Calculate the product

$142\times16.5 = 2343$

Step2: Add the remaining number

$15.11+2343=2358.11$

Step3: Determine significant - figures

142 has 3 significant figures, 16.5 has 3 significant figures, and 15.11 has 4 significant figures. When multiplying and adding, we go by the least number of significant figures in the multiplication operation for the final result. The product $142\times16.5$ has 3 - significant - figure precision. Rounding 2358.11 to 3 significant figures gives 2360.

Answer:

C. 2,360
