a.806.5
b.1159.5
c.2268.5
d.4174.5

A. 806.5 in²

Step-by-step explanation:

The figure given is a combination of a rectangle, a trapezoid and a triangle.

The formulas for the areas of each figure:

Rectangle: length x width

Trapezoid: , where and are the lengths of each base and h is the height of the figure

Triangle: 1/2 bh, b = base and h = height

For each of the figures given:

rectangle: 16 x 9 = 144 in²

trapezoid: = 352.5 in²

triangle: 1/2(31*20) = 310 in²

310 + 144 + 352.5 = 806.5 in²

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%

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.
