There are 18 South American butterflies and 12 European butterflies.

Step-by-step explanation:

The question is incomplete so the complete question is below:

The ratio of North American butterflies to South American butterflies at a butterfly park is 5:3.The ratio of South American butterflies to European butterflies is 3:2. There are 30 North American butterflies at the butterfly park.

How many South American butterflies are there and how many European butterflies are there ?

Now, to find the number of South American butterflies European butterflies are there.

Let the number of South American butterflies be

The North American butterflies = 30.

As, given the ratio of North American butterflies to South American butterflies at a butterfly park is 5:3.

So, 5 is equivalent to 3.

Thus, 30 is equivalent to

Now, to get the number of South American butterflies by using cross multiplication method:

$\frac{5}{3} =\frac{30}{x}$

By cross multiplying we get:

5x=90

Dividing both sides by 5 we get:

x=18.

The number of South American butterflies = 18.

Now, to get the number of European butterflies:

Let the number of European butterflies be

As, given the ratio of South American butterflies to European butterflies is 3:2.

So, 3 is equivalent to 2.

Thus, 18 is equivalent to .

So, to solve by using cross multiplication method:

$\frac{3}{2} =\frac{18}{y}$

By cross multiplying we get:

3y=36

Dividing both sides by 3 we get:

y=12.

The number of European butterflies = 12.

Therefore, there are 18 South American butterflies and 12 European butterflies.

The biologist has a second culture to examine. she knows that the population of the culture doubles every 15 minutes. after 1 hour and 15 minutes, her assistant found that 80,000 bacteria were present. a) what was the size of the initial population? b) predict the size of the culture at t=3 hours. what was the size of the population at 40 minutes? explain and justify your answers. c) create a graph of the population as a function of time. find an equation that can be used to predict the size of the population at any time t. d) examine the rate at which the bacteria culture is growing. how fast is the culture growing after 1 hour? after 1.5 hours? after 2 hours? use a time interval of h = 0.01 hours to estimate these rates. interpret these rates in terms of the context of the problem situation. how do these three rates compare?
