Cube-shaped blocks are packed into a cube-shaped storage container. The edge length of the storage container is 212 feet. The

igor_vitrenko [27]

Answer:

The volume of cube-shaped block is 0.125 cubic feet.

Step-by-step explanation:

We are given the following in the question:

Edge length of storage container =

$2\dfrac{1}{2}\text{ feet}$

Edge length of block =

$\dfrac{1}{5}\times \text{Edge length of container}$

Putting value we get,

Edge length of block =

$\dfrac{1}{5}\times 2\dfrac{1}{2}\\\\=\dfrac{1}{5}\times \dfrac{5}{2}\\\\=\dfrac{1}{2}\text{ feet}$

Volume of cube-shaped block = Volume of cube

$V = \text{(Edge)}^3\\\\V =(\dfrac{1}{2})^3\\\\V = \dfrac{1}{8}\text{ cubic feet}\\\\V = 0.125\text{ cubic feet}$

Thus, the volume of cube-shaped block is 0.125 cubic feet.

For each of the following, decide if the given series is a geometric series. A. 5+25x+125x2+625x3+3125x4+⋯ : Is this a geometric

Westkost [7]

Answer:

A. Yes.

B. Yes.

C. No.

Step-by-step explanation:

A. Yes. The sum of the series, $5 + 25x + 125x^{2} + 625x^{3} + 3125x^{4} + ...........$ is the sum of a geometric series.

The first term of the series $a_n$ = 5.

The common ration or the ratio between successive terms (r) = $\frac{25x}{5} = 5x$ (Answer)

B. Yes. The sum of the series, $5x^{7} + 5x^{8} + 5x^{9} + 5x^{10} + ............$ is also the sum of a geometric series.

The first term of the series $a_n = 5x^{7}$ .

The common ration or the ratio between successive terms (r) = $\frac{5x^{8} }{5x^{7} } = x$ (Answer)

C. No. The sum of the series, $5 + 5x + 5x^{2} + 5x^{4} + 5x^{8} + ...........$ is not the sum of a geometric series.

The first term of the series $a_n = 5$ .
