Question

A dairy cow can produce 5400 quarts of milk per year. Suppose there are about 6.4 million cows in the U.S.

Answer 1

Answer:

3.46 x $10^{10}$

Step-by-step explanation:

Number of cows 6.4 million = 6.4 x $10^{6}$

production rate for each cow per year = 5400 = 5.4 x 10³

Total amount of milk produced per year,

= 6.4 x $10^{6}$ x 5.4 x 10³

= (6.4) (5.4) x $10^{6+3}$

= 34.56 x $10^{9}$

= 3.46 x $10^{10}$
