Answer:

<em>20%</em>

Step-by-step explanation:

percent change = (new amount - old amount)/(old amount) * 100

percent change = (30 - 25)/25 * 100

percent change = 5/25 * 100

percent change = 20%

4. An initial population of 825 quail increases at an

OLga [1]

Answer:

A

Step-by-step explanation:

The general form of compound growth formula is:

$F=P(1+r)^t$

Where

F is the future amount

P is the initial amount

r is the rate of growth in decimal

t is the time in years

In the problem, initially there is 825 quail, so

P = 825

The future amount is given as "Y", so we will replace "F" of formula by "Y"

The rate of growth in 13%. This converted to decimal is:

13/100 = 0.13

The time is 3 years, so t = 3

Now, we substitute and find the model equation:

$F=P(1+r)^t\\Y=825(1+0.13)^3\\Y=825(1.13)^3$

Correct answer choice is A

The equation d = 3t gives the distance, d, in meters that Liam swims with respect to time, t, in seconds.

Natasha_Volkova [10]

Answer:

Liam's rate = 3 meters per second

Edgar's rate = 3.2 meters per second

Edgar swims faster

Step-by-step explanation:

<u>Liam:</u>

The equation $d=3t$ gives the distance, d, in meters that Liam swims with respect to time, t, in seconds.

When $t=0,\ d=0.$

When $t=1,\ d=3.$

Rate of change:

$\dfrac{3-0}{1-0}=3$

Liam's rate is 3 metres per second.

<u>Edgar:</u>

When $t=20, \ d=64.$

When $t=40,\ t=128.$

Rate of change:

$\dfrac{128-64}{40-20}=\dfrac{64}{20}=3.2$

Edgar's rate is 3.2 metres per second.

Edgar swims faster.
