SOVA2 [1]

<h2>Answer:</h2>

The dollars worth of zinc which is contained in hair cut in the United States every year is:

$ 2,220,000

<h2>Step-by-step explanation:</h2>

The total kilograms of hair that are cut in the United States are: 25,000,000 kg

Also, the amount of zinc present in 1kg of hair is: 0.0002 kg

Hence, the amount of zinc present in 25,000,000 kg of hair is:

25,000,000×0.0002=5,000 kg

Also, cost of 1 kg of zinc= $ 444

Hence, cost of 5,000 kg of zinc will be: 5,000×444

Hence, cost of 5,000 kg of zinc=$ 2,220,000

How do you know that 50 is not a perfect square?

Alexus [3.1K]

We can always do a prime factoring of it, and check

50 = 2*5*5
2*5²

a perfect square, so-called, is the resulting number of a squared value, well 50 is not the result of anything squared, is the result of 3 factors, in this case 2,5 and 5.

a perfect square will be something like say 64, or 144, because

64 = 8*8
8²

144 = 12*12
12²
