A cylindrical tank with a radius of 12 inches and a height of 20 inches is full of water. Does the tank have enough water to fil
Reptile [31]

Answer:

Yes, it can.

Step-by-step explanation:

To know if you can fill all the water balloons with the tank, the first thing is to calculate the volume of each one.

Volume of the tank, is a cylinder, whose volume is given as follows:

Vc = Pi * Rc ^ 2 * h

 

The radius of the cylinder has a value of 12 inches and the height of 20 inches. Thus:

Vc = 3.14 * (12) ^ 2 * 20 = 9043.2 inches ^ 3

Now, the volume of each globe that is a sphere is given by the following equation:

Ve = (4/3) * Pi * Re ^ 3

Being the radius of the sphere of 2, we have to:

Ve = (4/3) * 3.14 * 2 ^ 3 = 33.5 inches ^ 3

Now to know if you can fill all the balloons, we calculate the volume ratio of the tank and a balloon.

Vc / Ve = 9043.2 /33.5 = 269.95

Therefore, it can fill the 250 balloons because it has the capacity to carry approximately 269 balloons.

Use the Zero Product Property to find the x-intercepts for x^2+6x=y
Semmy [17]

Answer:

x=0\ or\ x =-6

Step-by-step explanation:

Given

x^2+6x=y

Required

Determine the x intercepts

To get the x intercepts, we simply set y to 0

Substitute 0 for y;

x^2+6x=0

Factorize:

x(x +6) = 0

Apply zero product property

x=0\ or\ x + 6 =0

x=0\ or\ x =-6
