9.9x10^8
9.9x10^11
9.9x10^9
9.9x10^10

Answer 1

The correct answer is c
Just multiply 22000 by 4.5 and then write it in the scientific notation

Answer 2

Option C -
`9.9 * 10^9`

Explanation:

Given : last year a large trucking company delivered
`4.5*10^5` tons of goods with an average value of $22,000 per ton.

To find : What was the total value of the goods delivered?

Solution : Let the average value per ton =t

Average value of the goods is $22,000 per ton(t),

`=(2.2* 10^4)/(t)`

Good delivered is
`4.5*10^5` tons (t).

Total value
`=(2.2* 10^4)/(t)* 4.5*10^5`

Total value
`=2.2* 4.5 * 10^9`

Total value
`=9.9 * 10^9`

Therefore, Option C is correct.
