Step-by-step explanation:
45.85*7%= 3.21 tax
45.85+3.21=49.06 total
Step-by-step explanation:
The given rational function defined by the equation:

where :k = average number of vehicles arriving at the gate per minute
r = average number of vehicles admitted by the park attendants
T = the average waiting time in minutes for each vehicle
a) k = 26 , r = ?, T = 30 seconds
T(r) = 30 seconds



on solving:
r = 0.016657 , 30.017
r = 30.017 (accept, given that r > k )
Admittance rate r that is necessary to keep the average waiting time T for each vehicle to 30 sec is 30.017.
b) k = 5.3, r = ?, T = 30 seconds
T(r) = 30 seconds

r = 0.016657 , 5.31672
r = 5.31672 (accept, given that r > k )
5.31672 park attendants will be needed to keep the average wait to 30 seconds.
Answer:
58
Step-by-step explanation:
we know angle MQR= angle XQL,
70-2b=28+5b
42=7b
b=6
angle MQR = 28+5b = 28+5(6) =58
