Answer:14 dimes 10 nickels
Step-by-step explanation:
24 coins total
14 X.10 = 1.40
10 x .05 = .50
1.40 + .50 = 1.90
The angular velocity is the linear speed divided by the radius.
ω = d/(t*r) = (14.13 ft)/((3 s)*(6 ft))
ω = 0.785 radians/second
There are 180/π degrees per radian, so the angular velocity can also be written as ...
ω = 45 degrees/second
She needs at least 130 points, so 130 - 75 (that she is earning from the sign up) = 65 points.
65 : 5,5 = 11,81 ≈ 12
So she has to sign up and visit he movie theatre at least 12 times to earn a movie ticket.
