You're dealing with "arc length" here, and the formula for that is s = r*theta, where r is the radius and theta is the central angle in radians (not degrees).
Thus, s = (12pi inches) = (10 inches)(theta), so
theta = the central angle (not the measure of the arc) = (12pi)/(10 inches), or
theta = 1.2*pi (no units of measurement)

Question One
The first question is just to derive a formula that represents the cost of anything bought in Idaho.
c = p + 6/100 * p
c = p + 0.6 * p
c = 1.06 p
Question Two
The second question requires an entirely different formula. You don't use the first formula. You just use it's idea. Further, you take the sales tax only when you know how much money has exchanged hands.
c = (p - 30/100 p) + 6/100*(p - 30/100 * p)
c = (p - 0.3p) + 0.06* (p - 0.3p)
c = 0.7 p + 0.06*(0.7p) Combine the right side
c = 0.7p + 0.042p Combine
c = 0.742p
33.39 = 0.742p Divide by 0.742
33.39/0,742 = p
p = 45 dollars
The original cost was 45 dollars
Answer:
I think the answer is
1.7142857144
Step-by-step explanation:
12 divide by 7
To find the length of each piece, you will divide 11/6 by 2.
11/6 x 1/2 = 11/12 feet
Each piece is 11/12 feet.
11/12 = 22/24
11/12 = 33/36
