Question

A dairy cow can produce 5,400 quarts of milk per year. There are 9.2 million dairy cows in the US. Use scientific notation to calculate about how much milk is produced in the US yearly.

(round to two decimal places)

Answer 1

5,400 = 5.4 x 10^3

 

9.2 million = 9.2 x 10^6 cows

 

yearly milk production = 5.4 x 10^3 x 9.2 x 10^6 = 49.68 x 10^9 quarts.
