Answer:

  13 nickels

Step-by-step explanation:

Let n represent the number of nickels Bob has. Then 18-n is the number of dimes, and the total value (in cents) is ...

  5n +10(18-n) = 115

  -5n +180 = 115 . . . simplify

  65 = 5n . . . . . add 5n-115

  13 = n . . . . . . . divide by 5

Bob has 13 nickels.

A farmer wants to build a new grain silo. The shape of the silo is to be a cylinder with a hemisphere on the top, where the radi
notsponge [240]

Answer:

The radius of the silo should be 16\ ft

Step-by-step explanation:

we know that

The volume of the grain silo is equal to the volume of the cylinder plus the volume of a hemisphere

V=\pi r^{2} h+\frac{4}{6}\pi r^{3}

we have

V=35,500\pi\ ft^{3}

h=4D=8r

substitute the values and solve for r

35,500\pi=\pi r^{2} (8r)+\frac{4}{6}\pi r^{3}

Simplify

35,500=r^{2} (8r)+\frac{4}{6}r^{3}

35,500=8r^{3}+\frac{2}{3}r^{3}

35,500=\frac{26}{3}r^{3}

r^{3}=35,500*(3)/26

r=16\ ft
