The amounts of food waste generated in a region during two years were 37,500,000 tons and 30,400,000 tons. What was the total food waste generated over these two years in the region, expressed in scientific notation? (5 points)
67.9 ⋅ 1014 tons
6.79 ⋅ 107 tons
67.9 ⋅ 107 tons
6.79 ⋅ 1014 tons
To calculate the total food waste generated over these two years, we add the amounts:
37,500,000 + 30,400,000 = 67,900,000
This can be expressed in scientific notation as 6.79 x 10^7 tons.
To find the total food waste generated over the two years, we need to add the amounts of food waste generated in each year.
Year 1: 37,500,000 tons
Year 2: 30,400,000 tons
Total = 37,500,000 + 30,400,000 = 67,900,000 tons.
We can express this number in scientific notation as follows:
67,900,000 tons = 6.79 x 10^7 tons.
Therefore, the total food waste generated over these two years in the region, expressed in scientific notation, is 6.79 x 10^7 tons.
To find the total food waste generated over the two years in scientific notation, we need to add the two given amounts of food waste together.
The first amount of food waste generated is 37,500,000 tons.
The second amount of food waste generated is 30,400,000 tons.
Now, add these two amounts together: 37,500,000 + 30,400,000 = 67,900,000 tons.
Expressing this amount in scientific notation, we need to move the decimal point to the right after the first non-zero digit. In this case, the first non-zero digit is 6, so we move the decimal point to the right once.
So, the total food waste generated over these two years in the region, expressed in scientific notation, is 6.79 × 10^7 tons.
Therefore, the correct answer is option C: 6.79 × 10^7 tons.
