Due to conservation efforts, the gray whale has been removed from the endangered species list. There are now 13,000 in the world
brilliants [131]

Answer:

P = 13,000(1.11) ^ t

Step-by-step explanation:

This scenario can be modeled using an exponential growth equation.

The exponential growth equations have the following form:

P = p (1 + r) ^ t

Where P is the population in year t

p is the initial population at t = 0

r is the growth rate

t is the time in years.

In this case we know that the current population is 13,000 and that the growth rate is 11%

So

p = 13,000\\r = 0.11

The equation that models this scenario is:

P = 13,000(1 + 0.11) ^ t

P = 13,000(1.11) ^ t

AURORKA [14]

Answer:

There are 60 activity booklets in the media lab.

Step-by-step explanation:

- 30/2 = 15

Why divide those numbers?

For every 2 computers in a lab with 30 computers means you have to divide

- 15x4 = 60

Why multiply those numbers?

4 activity booklets for every 2 computers in a lab of 30 computers, so multiply

I hope this helps.

sleet_krkn [62]

Answer:

213 euros per month

Step-by-step explanation:

1dollar = 0.7306euros

thus $3,500 dollars can be found by a rule of three

dollar             euro

1             ⇒  0.7306

3500     ⇒        x

we find x as follows:

x=\frac{0.7306*3500}{1} = 2,557.1 euros

She will pay 2,557.1  euros per year.

Dividing between the 12 months of the year:

\frac{2,557.1}{12}=213.1

Rounding to the nearest whole euro she will pay 213 euros per month.
