How many zeros are in 10 to the 7th power when it is written in standard form

8 zeroes. You add 7 zeroes on, but you have the initial zero from the 10.

When rates are expressed as a quantity of 1, such as 2 feet per second or 5 miles per hour, they are called unit rates. if you have a multiple-unit rate such as 120 students for every 3 buses, and want to find the single-unit rate, write a ratio equal to the multiple-unit rate with 1 as the second term.
