Thermonuclear weapons use tritium, a radioactive form of hydrogen, for their nuclear reactions. Tritium decays at a rate of 5.613% per year. Safeway Labs stocks 300 pounds of Tritium. How much Tritium will
they have in 20 years? In how many years will they have 100 pounds of Tritium?

true

step-by-step explanation:

3,6 and 7.

step-by-step explanation:

a) unit place of 37 is 7

so the unit place of cube of 37 will be

7³= 343=3

the answer is 3.

b) unit place of 56 is 6, so the unit place of cube of 56 will be

6³= 216=6

the answer is 6.

c) unit place of 133 is 3, so the unit place of cube of 133 will be

3³= 27= 7.

the answer is 7.
