Answer:
Bernie, Chrissy, Dina and Frank
Step-by-step explanation:
if all 73 tickers are sold, the theatre makes $438 so each ticket is worth $438/73
this equals to $6.00 for one ticket
this means that Bernie, Chrissy, Dina and Frank have enough money to see the movie
2/3 of 8 miles is 5 and 1/3 miles. So they walked about 5 and 1/3 miles there.
Answer:
the ball is in the air for 8 seconds
Step-by-step explanation:
f(x) = y
when y = 0, the ball would've travelled through the air over the final time of flight.
0 = -5x^2 + 40x + 0
use quadratic equation to find the value of x
x = (-b ± √b^2 - 4 • a • c) / 2 • a
x = (-40 ± √40^2 - 4 • -5 • 0) / 2 • -5
x = (-40 ± √1600) / - 10
x = (-40 ± 40) / - 10
x = 0 or x = 8
