To find the weight of this sand you will use the formula for finding the volume of a cone and then multiply this by 100.  The volume will give us the number of cubic feet.

V = 1/3 x B x h (B is the area of the circle)
V = 1/3 x (pi x r^2) x h
      1/3 x 3.14 x 3.75^2 x 4.5
V = 66.23 cubic feet

66 cubic feet x 100 = 6600 pounds

The sand weighs approximately 6600 pounds.

Jeff has $1.35 in nickles and dimes. He has a total of 15 coins. How many of each coin does he have?
dlinn [17]

For this case we propose a system of equations.

We know that a dime equals 10 cents and a nickel equals 5 cents.

So:

x: Let the variable that represents the number of dimes

y: Let the variable that represents the number of nickels

According to the statement we have:

x + y = 15\\0.10x + 0.05y = 1.35

We multiply the first equation by -0.10:

-0.10x-0.10y = -1.5

We have the following equivalent system:

0.10x + 0.05y = 1.35\\-0.10x-0.10y = -1.5

We add the equations:

0.10x-0.10x + 0.05y-0.10y = 1.35-1.5\\-0.05y = -0.15\\y = \frac {-0.15} {- 0.05}\\y = 3

So, Jeff has 3 nickels

x + y = 15\\x + 3 = 15\\x = 15-3\\x = 12

Jeff has 12 dimes.

Answer:

12 dimes and 3 nickels
