Answer:
in 13.95 years the senior class will have 100 students.
Step-by-step explanation:
P(h) = p(0.92)^t (equation for exponential change)
P(h) - population of highschool (or senior class) = 100
p - staring amount = 320
t = time in years
100 = 320(0.92)^t
1/3.2 = .92^t (divide both sides by 320)
log(1/3.2, .92) = t (log base 0.92 of 1/3.2 equals t)
13.9497 = t
I would go with A but I am not 100% sure so you may want to check however you can.
Caroline, Colin & Sarah share some money.Caroline will get
when Caroline, Colin & Sarah share some money.
<h3>What is the ratio?</h3>
The ratio defined as the sharing of the two or three things or it represent that one thing or number is how many times to the other.
One part is excluded in the problem. That part is:
"Caroline gets
of the money."
If Caroline gets 1/9th, then remaining is:

Colin and Sarah share in ratio 3 is to 1, that means 3 + 1 = 4 parts...
8/9th in 4 parts means, each part is:

We know Colin gets "3" parts of the total, each part is (2/9)th, so 3 parts would be:

Colin gets
money when three of them share money.
