Arla bakes banana bread in a pan that measures 10 in. long, 12 1/2 in. wide, and 2 in. tall. she decides to cut pieces of bread that measure 2 in. by 2 1/2 in. by 2 in.

10 times 12 1/2 times 2 = 250      2 times 2 1/2 times 2 = 10 so 250 divided by 10 = 25   So in conclusion 25 is the answer.

Mg remaining = (initial amount in mg) (1/2^(t/h)) where h = half-life

1.

a.
mg remaining = (500) (1/2^(3/4)
= 297.3 mg
b.
mg remaining = (500)(1/2^(8/4))
= 125 mg
