Element X decays radioactively with a half life of 15 minutes. If there are 230 grams of Element X, how long, to the nearest tenth of a minute, would it take the element to
decay to 33 grams?

answer: 1,380

step-by-step explanation:

1: you turn %15 into a decimal by moving the decimal point two places to the left.

2: and then you multiply .15 by 1,200 , which will get you 180.00

3: from there you will add 180 to 1,200

4: which will get you 1,380
