Perform the following
Marianna [84]

Answer:

167.980.

Explanation:

Hello!

In this case, since additions involving the display of the result with the appropriate number of significant figures involve the solution of the system without looking at them:

156.325 +11.65498 =167.97998

Considering that 156.325 is significant to the thousandths and 11.65498 to the hundred thousandths, we infer that the result should be taken to the thousandths as well as 156.325; thus, we obtain:

167.980

Because the second decimal nine is rounded to ten and therefore the 7 is taken to 8.

Best regards!
