MatroZZZ [7]

Answer:

126807 people

Step-by-step explanation:

Given;

P= Poe^ht

Where;

P= population at time t

Po= population at the beginning

h= growth constant

t= time

1998- 2008 is ten years.

110429= 100,000e^10h

1.1 = e^10h

ln(1.1) = lne^10h

0.095 = 10h

h= 0.0095

In 2023, t = 25 years

P= 100,000e^(0.0095 × 25)

P= 126807 people

Thirty-six of the students in the school choir like to sing solos. These 36 students make up 24% of the choir. How many students

lubasha [3.4K]

Answer:

150

Step-by-step explanation:

We can write a proportion to find the total amount in the choir using the information given. A proportion is two equivalent ratios set equal to each other.

$\frac{24}{100}=\frac{36}{y}$

We will cross multiply the numerator of one ratio with denominator of the other. And then solve for y.

24y=100(36)

24y=3600

y=150.

There are 150 students in the choir.
