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 the hundredths place)

Answer 1

we know that

$5,400\ quarts = 5.4 * 10^3\ quarts$

 $9.2\ million\ cows = 9.2 * 10^6 \ cows$

 so

Find the yearly milk production

$= (5.4 * 10^3) * (9.2 * 10^6) = 49.68 * 10^9\ quarts$

therefore

the answer is

$49.68 * 10^9\ quarts$
