a. 0.002
b. 0.0001
c. 0.0002
d. 0.0021

Answer 1

To evaluate the expression with the appropriate number of significant figures, perform the multiplication and division, then round the result to three significant figures.

Step-by-step explanation:

To evaluate 2.80 / (5)(135) with the appropriate number of significant figures, first perform the multiplication:

(5)(135) = 675

Then divide 2.80 by 675:

2.80 / 675 = 0.004148148

Since the original number 2.80 has three significant figures, the final answer should also have three significant figures. Rounding the result to three significant figures gives us the answer of 0.00415.
