A rectangle has a perimeter of 186 kilometres and a height of 37 kilometres. What is the length of the base?

Step-by-step explanation:

Perimeter of rectangle=2(height+base)

Given perimeter=186km

Height=37 km

So 186=2(37+base)

93=37+base

Base=93-37=56 km

the aswere is the one with all 8's and the second one is with the 10,8 and 6

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.
