Answer:
Half life of the radioactive element is 5 days.
Step-by-step explanation:
Formula to get the final amount after the radioactive decay in 't' days,
Here = Initial amount
λ = Decay constant
t = duration of decay
= Final amount
0.01 =
ln(0.01) =
-4.6052 = -34λ
λ = 0.13544
Since, λ =
= 5.11
≈ 5 days
Therefore, half life of the radioactive element is 5 days.
Answer:
30/100 or 3/10
Step-by-step explanation:
A percent is out of 100. So since 30 is an even number then it would be 30/100 or 3/10.
