Rebecca needs 10.yards of fabric to make a quilt. She has one piece of fabric that is 25 yards and another piece of fabric that is 45 yards. How many more yards of fabric does
Rebecca need to make the quilt?
How many yards of fabric does Rebecca need to make the quilt.

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.  

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,

they charge the same amount at 20 minutes.
