Answer:
The answer is A Lma/o
Step-by-step explanation:
Represent the decay of the substance by the equation
where
m₀ = initial mass
k = decay constant
t = time, years
Because the half life is 18 years, therefore
When m(t) = 63% of m₀, obtain
Answer:
The substance decays to 63% of its original amount in 12 years.
Answer:
Step-by-step explanation:
The total number of marbles is 24 + 36 + 60 = 120
