The ratio is 7:10 or 3.5:5
Answer:
F(4) = 23
Step-by-step explanation:
Find F(4) also means finf F = 4x + 7 when x =4
When x = 4, it would be:
F = 4*4 +7
F = 16 + 7
F = 23
F(4) = 23

Answer:
There are 20 European Butterflies.
Step-by-step explanation:
To determine the number of European Butterflies in the park, knowing that there are 80 North American Butterflies there, and that the ratio of each species is 8: 5 for North American and South American butterflies, and 5: 2 for South American and European butterflies, it must be done the following logical reasoning:
Given that there are 8 North American butterflies for every 5 South American, and 5 South American for every 2 European, it could be said that there are 8 North American butterflies for every 2 European (8: 2).
Thus, if there were 80 North American butterflies, the number of European butterflies in the park would be 20.
