Farmer joe has a rectangular pasture that is fenced in for his cattle. he bought some horses and wants to cut the pasture in half diagonally from corner to corner.

250

Step-by-step explanation :By drawing in the diagonal a right triangle is formed with legs of 150 and 200, using the Pythagorean theorem the diagonal is found to be 250 yards long. So 250 yards of fencing is needed

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.  

v = 1/3 a^2h

step-by-step explanation:

if the height is 57.7cm and the height of the slant edge is 18.2cm, then the volume is 1/3 a^2h.
