Step-by-step explanation:
Given Area of Circle B = Area of Circle A
Given r = 1/2d = 1/2(16) = 8 in
and Area of Circle =
2a + 7b = 0 ⇒ 10a + 35b = 0
3a - 5b = 31 ⇒ 21a - 35b = 217
31a = 217
a = 7
2a + 7b = 0
2(7) + 7b = 0
14 + 7b = 0
7b = -14
b = -2
(x, y) = (7, -2)

Answer:
127.31
Step-by-step explanation:
127.31
Answer:
33%
Step-by-step explanation:
Prob(heads) = 1/2
Prob(either red or blue) = 2/3
So Prob( heads and red/blue) = 1/2 * 2/3
= 2/6
= 1/3 which is 33%.
