during a movie matinee, the film projector broke. the theater manager refunded the ticket price to everyone attending let n represent the number of people watching the movie. let r represent the total amount of money refunded. write an equation to represent the amount of money refunded. Movies Prices: Adults $8.50, Children $7.00 and Matinees All Ages $5.00

47 - 90 = 43

43 - 180 = x

x = 137

7.9m and 4.3°

step-by-step explanation:

let east be +x and north be +y, x = distance * cos θ, y = distance * sin θ  

for 3.5 south, y = -3.5  

for 8.2, x = 8.2 * cos 30 and y = 8.2 * sin 30  

for 15 west, x = -15  

total x = 8.2 * cos 30 – 15 ≈ -7.9  

total y = -3.5 + 8.2 * sin 30 = 0.6  

magnitude = [(8.2 * cos 30 – 15)^2 + 0.6^2)]^0.5  

the magnitude is approximately 7.9 m  

tan θ = y/x = 0.6/-7.9  

the angle is approximately 4.3˚ north of west
