Answer: The Answer is 12
Step-by-step explanation: This is because each number's LCM (Least Common Multiple) is 12. Ex. 4,8,12 3,6,9,12 6,12
You would put in 12 for x since there are 12 months in a year. Then you would multiply 12 by 35, and add 70.
I'm gonna send you a picture because it'll explain the answer better
If the half-life is t, then every t days, the amount of the radioactive isotope will be cut in half.
(1/2)^(number of half-lives) = 3%
number of half-lives = ln(0.03) / ln(0.5)
This gives the number of half-lives as 5.06.
Then 300 days = (5.06)(length of 1 half-life)
length of 1 half-life = 300 / 5.06 = 59.29 days
1 3/6 + 4/6 = 1 7/6 = 2 1/6
