In preschool there is a ratio of 3 boys for every 4 girls. If there are 24 girls, then how many boy are in class?

Step-by-step explanation:

If there is 3:4 then if we know there is 24 girls then we can fill it in.

3:4=x:24

3/4=x/24

4x=72

x=18

or

we can just do 24 divided by 4 where we get 6 so we just do 3 times 6 which is also 18.

hope this helps

answer is the third choice:

3x^5+4x^4+x^3+2x^2-10x-7=0

step-by-step explanation:

the answer is; biodiversity resulting from few ancestors

adaptive radiation occurs when a population is subjected to a large natural environment with spatial ecological variations. the parts of the population in the different ecologies begin to adapt to their local environments. due to non-random mating across the large populations, this causes the different populations from the large population to speciate within their local environments. they, therefore, diverge to different species sharing a common ancestor.
