Answer:
n = 16
Step-by-step explanation:
3n + 4 = 52
subtract 4 from each side
3n+4 -4 = 52-4
3n = 48
divide by 3 on each side
3n/3 = 48/3
n = 16
Answer:
Answer is A
Step-by-step explanation:
Elisa, e = 11mins
Prenav, p = 13mins
time to finish, t
1 = t( 1/11 + 1/13) = t (24/143)
The amount remaining after 171 hours is 18.75 grams
<h3>How to calculate Exponential Decay?</h3>
Nuclear half-life expresses the time required for half of a sample to undergo radioactive decay. Exponential decay can be expressed mathematically like this:
A(t) = A₀(¹/₂)^(t/t_1/2)
where;
A (t) - the amount left after t years;
A₀ - the initial quantity of the substance that will undergo decay;
t_1/2 - the half-life of the decaying quantity.
We are given;
t_1/2 = 57 hours
t = 171
A₀ = 150
Thus;
A(171) = 150 * (¹/₂)^(171/57)
A(171) = 150 * 0.125
A(171) = 18.75 grams
Thus, the amount remaining after 171 hours is 18.75 grams
