Answer:
90/361
Step-by-step explanation:
1. Find the probability to grab a red and blue sock.
p(red sock) = 10/19
p(blue sock) = 9/19
2. Multiply the two probabilities.
10 x 9 = 90
19 x 19 = 361
3. Simplify only if it is possible to do so.
4. The answer is 90/361.
Add 16+12 to get 28.
Add 9+12 to get 21.
Think of these as the sides of a triangle.
a^2+b^2=c^2
28^2+21^2=1225
√1225=35
You threw the ball 35 feet.

Answer: x = 140 (choice C)</h3>
========================================================
Explanation:
Focus on the upper semicircle. It's composed of the arc pieces that are 30 degrees, x degrees, and y degrees. The y is the missing unmarked portion of the upper semicircle.
Subtract the 30 and y degree angles, divide by 2, and set that result equal to 10. This will help us solve for y
(30-y)/2 = 10
30-y = 10*2
30-y = 20
-y = 20-30
-y = -10
y = 10
Because the 30, x and y arcs form a semicircle, this must mean the three arcs add to 180 degrees
30+x+y = 180
30+x+10 = 180
x+40 = 180
x = 180-40
x = 140
