Answer: 45


Step-by-step explanation: 21 x 3 = 63, because 3x3 is 9. 9 tickets with a $2 discount would mean you take off $18, so I believe the answer would be 63-18=45.

The maximum flow of water in a pipe is modeled by the formula Q=Av, where A is the cross-sectional area of the pipe and V is the
Ira Lisetskai [31]
For this case we have the following equation:
 Q = Av
 Where the area is given by:
 A = pi * r ^ 2
 A = pi * (d / 2) ^ 2
 A = (pi / 4) * d ^ 2
 Substituting we have:
 Q = ((pi / 4) * d ^ 2) v
 From here, we clear the diameter:
 d = root ((4 / pi) * (Q / v))
 Substituting values we have:
 d = root ((4 / pi) * (50/600))
 d = 0.36 feet
 Answer:
 
The diameter of a pipe that allows a maximum flow of 50ft ^ 3 / min of water flowing at a velocity of 600ft / min is:
 
d = 0.36 feet

The lid for a circular plastic food container has a diameter of 9 cm.
Levart [38]
If the diameter is 9 cm the radius is 4.5 cm (half the diameter).  The area of a circle is given by the formula:  4πr^2, where π is the constant ratio of circumference to diameter (3.14159...).

3.14 cm x 4.5 cm = 14.13 cm^2.  Remember, the units must be squared to represent area.  14.13 is extended to the nearest hundredth.
