Answer:

  • 8 AM

Step-by-step explanation:

  • Start time = 2 PM
  • Speed of the first train = 50 mph
  • Speed of the second train = 60 mph
  • Trains head same direction
  • The second train spends 3 hour less time than the first but both take same distance

<u>Let the time in travel for the first train be x, then we have equation for distance:</u>

  • 50x = 60(x - 3)
  • 50x = 60x - 180
  • 60x - 50x = 180
  • 10x = 180
  • x = 18 hours

<u>Time when the second train caches up the first one:</u>

  • 2 PM + 18 hours = 8 AM next day

The volume of the plastic cylinder is 64. A glass cylinder has the same height and radius is half of the plastic cylinder radius
sp2606 [1]

Answer:

I am not sure if I'm correct, but I got 16

Step-by-step explanation:

lets look at the formula for cylinder volume:

V=π*r^(2)*h

now, lets plug in 64

64=π*r^(2)*h

h=64/(π*r^(2))

Volume of glass cylinder is

V=((0.5r)^2)*(64/(π*r^(2)))*π

V=0.25π*r^(2)*(64/(π*r^(2)))

V=16π*r^(2)/(π*r^(2)

V=16
