B is the answer. Look at the first word, Conditional. That means that something has to happen in order to work. Such as, your parent making you do your chores before you can go play with your friends. Hence you have to win a first game in order to win a second.

What is the approximate area of the shaded portion of the diagram? (Use 3.14 as an estimate for pi.)

Nadusha1986 [10]

Answer:

218

Step-by-step explanation:

first find the area of the circle-

$A=\pi r^{2} \\A=\pi 10^{2} \\A=100\pi \\A=314$

to find the area of the triangle, we need the base and the height. The base we know is 16, since we don't know the height yet, use the Pythagorean theorem to find the height. One leg is 16 the hypotenuse is 20 (2* the radius).

$a^{2} +b^{2} =c^{2} \\a^{2} +16^{2} =20^{2} \\a^{2} +256=400\\a^{2} =144\\a=12$

Now I know the height is 12. Find the area of the triangle

$A=\frac{1}{2} bh\\A=\frac{1}{2} (16)(20)\\A=96$

subtract the area of the triangle from the area of the circle

314-96=218

The average of a b c and d is p. If the average of a and c is q, what is the average of b and d in terms of p and q?

vodka [1.7K]

P - q i believe because
p = total average
q = average of ac
x = average of bd
p - q = x
