Answer:

7.4 x 10 to the 9th power

Step-by-step explanation:

At the end of numbers, there is a decimal point. when writing in function notation, you bring the point to the left or to the right depending on if it is a negative or a positive number

in this problem, you are dealing with a positive number, so bring the decimal point to the left. count how many numbers it takes to get in between, in this number, 7 and 4. it takes 9 spaces to the left. now the decimal point has been moved, your number goes from 7,400,000,000 to 7.4 x 10 to the 9th power(7.4 x 10^9)

A baker has 10 cups of sugar to make cookies.
marin [14]
That would be 7 and a half. 7 1/2. You can make seven and a half batches of cookies if the recipe calls for 1 1/3 cups of sugar each and a baker has 10 cups of sugar.
