Question

The amounts of paper waste generated in a region during two years were 41,300,000 tons and 50,500,000 tons. What was the total paper waste generated over these two years in the region, expressed in scientific notation? (1 point) 91.8 ⋅ 107 tons 91.8 ⋅ 1014 tons 9.18 ⋅ 1014 tons 9.18 ⋅ 107 tons

Answer 1

It's easier to add these first and then change to SN.

41,300,000 + 50,500,000 = 91,800,000

SN needs to change to this format:

9.18 x 10^7

Answer 2

Answer: $9.18\times10^{7}\text{ tons}$

Step-by-step explanation:

Given : The amounts of paper waste generated in a region during two years were 41,300,000 tons and 50,500,000 tons.

Then, the total paper waste generated over these two years in the region :-

$41,300,000+50,500,000=91,800,000$

In scientific notation,

$91,800,000=9.18\times10^{7}$

Hence, the total paper waste generated over these two years in the region =

$9.18\times10^{7}\text{ tons}$
