Using a system of equations, it is found that Peter had $48 at first.

<h3>What is a system of equations?</h3>

A system of equations is when two or more variables are related, and equations are built to find the values of each variable.

In this problem, the variables are:

  • Variable x: Peter's money.
  • Variable y: Henry's money.

The ratio of peters money to henrys money is 4 : 3, hence:

\frac{x}{y} = \frac{4}{3}

After Peter spent $12, they had the same amount, hence:

y = x - 12.

Then, replacing in the ratio:

\frac{x}{y} = \frac{4}{3}

\frac{x}{x - 12} = \frac{4}{3}

4(x - 12) = 3x

x = 48.

inna [77]

Answer:

The volume of the sphere is V=18\pi\ ft^{3}

Step-by-step explanation:

we know that

The volume of cylinder is equal to

V=\pi r^{2}h

we have

V=27\pi\ ft^{3}

substitute

27\pi=\pi r^{2}h

simplify

27=r^{2}h

Remember that

A sphere and a cylinder have the same radius and height

so

The height of cylinder is equal to the diameter of sphere

h=2r

substitute

27=r^{2}(2r)

13.5=r^{3} -----> equation A

The volume of the sphere is equal to

V=\frac{4}{3}\pi r^{3}

substitute equation A in the formula of the volume of sphere

V=\frac{4}{3}\pi (13.5)

V=18\pi\ ft^{3}
