Answer:
12
Step-by-step explanation:
12-n/2=6
-n/2= -6
n/2=6
n=12
The equation to solving this is 90/40 = 88 / X
knowing this I multiply 40 and 88 and 90 and x. I got 3520 and 90x. Now I divide 3520 by 90 and I get 39 and 1/9. So the time for the sample to decay is:
39 1/9 years.
Answer:
20t+20 ≤ 93
20t ≤ 73
t ≤ 73/20, or 3.65
