The answer is 441 because 2,792-146/ (divided) by6= 441
(.1mi/1min)
1.39mi/13.9 min
You have to multiply the bottom and the top by the same number to get the answer, you're trying to make the denominator 13.9 for the amount do minutes so you multiply the numerator by 13.9 to get the numerator
4.8 inches would be equal to 60 miles.
1 7/10 and that is as simple as it gets because there is nothing multiplied to equal 7 or ten together. :)
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
