Three consecutive odd numbers have a sum of 45. what is the greatest number?
rodikova [14]
Let's assume the middle number is x
then the smallest number is x-2
the greatest number is x+2
so the sum of the three number would be (x-2)+x+(x+2) and it equals 45
now we have an equation (x-2)+x+(x+2)=45
then we solve it 3x=45
x=15, which means the middle number equals 15
so the greatest number would be x+2=15+2=17
17 is the greatest number

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
