Answer 1

I THINK THE ANSWERE IS =B

Answer 2

The correct answer is B.
`(4.0).(10)^(3)`

Explanation:

The radio station advertised the Olympia Marathon by saying that about 12,000,000 calories would be burned in one day.

If we suppose that each runner burn the same amount of calories, in order to find the calories that each runner burn, we need to divide the total amount of calories by the total amount of runners.

• The total amount of calories is 12,000,000
• The total amount of runners is 3000

The division to solve this problem is :

`(12,000,000(calories))/(3000(runners))=((4.0).(10)^(3)(calories))/(runner)`

We find out that each runner will burn
`(4.0).(10)^(3)` calories in the marathon.

The correct option is B.
