17/15 - 4/5 please answer

5/15 or 1/3

Step-by-step explanation:

First, find a common denominator between the two fractions. 5 is the denominator of 4/5. 5 goes into 15, 3 times. So, multiple 4/5 by 3/3 and get 12/15. This puts the two fractions as fractions of 15. Now, subtract 12/15 from 17/15 and you get 5/15. If you simplify that by dividing by 5 on the numerator and denominator, you get 1/3. Hope this helps :)

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.  

answer: the distance

step-by-step explanation:

to calculate the distance d of a line segment with endpoints (x1, y1) and (x2, y2) use the formula d (x2 x1)2 (y2 y1)2. to calculate the midpoint of a line segment with endpoints (x1, y1) and (x2, y2) use the formula
