Answer:

7 $5 bills, 32 nickels

Step-by-step explanation:

Ok, so to solve this, we need to make two separate equations. If we say that x is the number of nickels, and y is the number of 5 dollar bills, adding up to $36.60, we can make the equations 0.05x + 5y = 36.60, and x + y = 39. Using substitution, we can say 0.05x + 5(39-x) = 36.60. This simplifies to 195-4.95x = 36.6. We can then say 158.4 = 4.95x, and x = 32. This means we have 32 nickels. As there are 39 total coins and bills, that means there are 7 $5 bills, and 32 nickels.

The volume of the cone shown below is 108pie cm^3. What is the value of H?
saw5 [17]

Answer:

h = 4cm

Step-by-step explanation:

Diameter = 18cm

Radius = Diameter/2 = 18/2 = 9cm

V = 1/3*pi*r^2*h

We know that the volume is 108pi cm^3. We can just plug in 108pi cm^3 for V and we also know that our Radius (r) is 2.

So,

108 pi = 1/3*pi*9^2*h

108 pi = (81pi*h)/3

multiply 3 from both side

108pi*3 = (81pi*h)/3 *3

324pi = 81pi*h

Now divide the 81pi from both side

324pi/81pi = (81pi*h)/81pi

4 = h

So the height is 4cm
