Answer:
Arc length is 
, or, 14.7
Step-by-step explanation:
AB is an arc intercepted by 140 degree angle. The formula for length of an arc is given by
Where
AL is the arc length
is the angle (in our case, 140)
r is the radius of the circle (which is 6)
<em>Substituting, we get:</em>

Answer:
32
Step-by-step explanation:
First, one theorem states that (arc AB - arc AX) / 2 = angle ACB. We know that arc AB is 176, so we have
(176 - arc AX) /2 = ∠ACB
Next, the Inscribed Angle Theorem states that
arc AX/2 = ∠ABX
multiply both sides by 2
56 * 2 = arc AX = 112
Therefore, ∠ACB = (176-112)/2 = 64/2 = 32
Answer:
Step-by-step explanation:
Given that your friend tossed a fair coin when you weren’t around.
Let A be the event that she said the outcome is head
B1 = Event she lied and B2 = Event she did not lie
P(AB1) = 
P(AB2) = 
Required probability = P(B1/A)=
Answer: Choice A) 3x+4y = 12
---------------------------------------------------------------------
y = (-3/4)x + 3
4*y = 4*((-3/4)x+3) ... multiply both sides by 4 to clear out the fraction
4y = -3x+12 ... distribute and multiply
4y+3x = -3x+12+3x ... add 3x to both sides
3x+4y = 12
Note: this is in standard form Ax+By = C where A = 3, B = 4 and C = 12.
