Adance school has 63 ballet dancers. if 42% of the total number of dancers in the school are ballet dancers, what is the total number of dancers in the school?

it's 105 ballet dancers

Step-by-step explanation:

because if it's 63 ballet dancers and 42 of the total students

t = 3

step-by-step explanation:

put t = 3 in this expression :

(3²-1)(3²-2)(3² - 3)(3² - 4) = 8×7×6×5 = 56×30 = 1680

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.
