anonymous · Answer

Im pretty sure its A

anonymous · Answer

No, that is not your answer.

anonymous · Answer

This is the number: 2232000.00
Look at the decimal place, and look at the choices. How far the decimal place is moved, it will be the number that is the power to 10.

anonymous · Answer

so its c?

anonymous · Answer

And plus, for a number to be in scientific notation, it needs to be greater than 0 and less than 10, so which choices can we eliminate? @horsegirl325

anonymous · Answer

so what is it??

anonymous · Answer

It should be 2.232*10^9 but, thats not an option.

anonymous · Answer

@YesThisIsDog That would be too big.

anonymous · Answer

@horsegirl325 This is the number: 2232000.00

We need to move the decimal place so the number is in between 1 and 10, so where would we move it?

anonymous · Answer

No, if you take 2.232*10^9, youd move the decimal place 9 places to the right. so youd get 2,232,000,000 Which 186,000*12

?

anonymous · Answer

@YesThisIsDog You're calculating it wrong. 186,000 x 12 = 2232000

anonymous · Answer

Oops! I put in a few extra zeros in my calculator @AnswerMyQuestions 

So, it would be 2.232*10^6
