The answer is B 10 1/2 Hours
1/4
4 dogs, one box. each dog gets one fourth of the box
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:
24 yd^2
Step-by-step explanation:
There's a large rectangle here, 4 yd wide and 8 yd long. The area of this large rectangle is 32 yd^2.
The smaller rectangle is 4 yd long and 2 yd wide, and so its area is 8 yd^2.
The area of the figure is thus 32 yd^2 - 8 yd^2, or 24 yd^2.
