Write 3,200 in scientific notation
spin [16.1K]

Answer:

The answer is 3.2 E 3 or 3.2 x 10^3

You move back 3 spaces which is 3.2, since you moved back 3 spaces, you put 3 as the power/exponet.

To be more satisfied, 3.2 is your base number, it is the big number Below the power/exponent. The power/exponent is 3, you moved 3 spaces and you moved to the left, so it is represented as a positive power/exponent.

Hope this helps.

Bill charges $12 per hour for a plumbing job. Write the equation that shows the relationship between the numbers of hours Bill w
yarga [219]

Answer:

m = 12h

Step-by-step explanation:

Since Bill charges $12 per hour, it implies for every hour he charges $12. Therefore, the amount of money he makes, m, is dependent on the number of hours he works, h. The higher the number of hours, the more his money. And vice versa.

So that;

m = 12h

Thus if Bill works for 6 hours, his amount of money would be;

m = 12 (6)

   = 72

m = $72

Bill would make $72 after working for 6 hours.
