k: the number of Kurds
t: the number of Turks
k=k
t=4k
k+t=66,000,000
k+4k=66,000,000
5k=66,000,000
k=13,200,000
t=52,800,000

1km is 1000 m
1000m+125m-375m=750m
The mass of radioactive material remaining after 50 years would be 48.79 kilograms
<h3>How to determine the amount</h3>
It is important to note that half - life is the time it takes for the amount of a substance to reduce by half its original size.
Given the radioactive decay formula as
m(t)=120e−0.018t
Where
t= 50 years
m(t) is the remaining amount
Substitute the value of t


Find the exponential value
m(t) = 48.788399
m(t) = 48.79 kilograms to 2 decimal places
Thus, the mass of radioactive material remaining after 50 years would be 48.79 kilograms
