Solution by Formulas
converting mixed numbers to fractions, our initial equation becomes,
−11 -9
3×4
Applying the fractions formula for multiplication,
−11×−9
3×4
=99
12
Simplifying 99/12, the answer is
=814

There are two hemispheres in there with radius 3 cm, so we can consider it as a whole one. and the other shape in between is Cylinder with radius 3 cm and height 4 cm.
Volume of whole ahape = volume of Cylinder + volume of sphere ~
<u>Volume</u> <u>of</u> <u>sphere</u> :
<u>Volume</u> <u>of</u> <u>Cylinder</u> :
<u>Volume</u> <u>of</u> <u>whole</u> <u>shape</u> :
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.
