Answer:
35 years
Step-by-step explanation:
The proportion p that remains after y years is ...
p = (1/2)^(y/5.27)
In order for 1/100 to remain (the level decays from 100 times to 1 times), we have ...
.01 = .5^(y/5.27)
log(0.01) = y/5.27·log(0.5) . . . take logs
y = 5.27·log(0.01)/log(0.5) ≈ 35.01 ≈ 35 . . . . years

Answer:
13.5
Step-by-step explanation:
13.50 is already rounded to the nearest tenth because the 5 is in the tenth place.
13.50 is basically 13.5
If you're looking for 13.5 rounded to the nearest ones or whole number, the answer would be 14 because any number that is five or greater is rounded up while any number that is four or less is rounded down.
