The volume of the prism is a function of the cubes in it.

The volume of the prism is: <em>(b) 2 unit cubes and 9 smaller cubes of volume fraction 1 over 27 cubic inch each</em>

From the question, we have:

<em />n = 63<em> --- number of cubes</em>

<em />l = \frac 13<em> --- the edge length of each cube</em>

<em />

So, the volume of a cube is:

v = l^3

This gives

v = \frac 13^3

v = \frac 1{27}

The volume of the prism is then calculated as:

V = n \times v

This gives

V = 63 \times \frac 1{27}

V = \frac {63}{27}

Rewrite as:

V = \frac {54 + 9}{27}

Split

V = \frac {54}{27} + \frac{9}{27}

V = 2 + \frac{9}{27}

Rewrite as:

V = 2 + 9 \times \frac{1}{27}

The above equation means that, the volume of the prism is:

<em>(b) 2 unit cubes and 9 smaller cubes of volume fraction 1 over 27 cubic inch each </em>

A skier is trying to decide whether or not to buy a season ski pass. A daily pass costs ​$68. A season ski pass costs ​$300. The
lina2011 [118]

first, ignore the rent for the skies. we could add it to both, but since it's the same, it would not change the number of days here.

this information is meant to test your decision making on what's important for the question.

now just ask how often you can pay $68 dollars per day while staying below 300 in total, you can just count it up.

68, 136, 204, 272, 340

its 4 days

for 5 days or more, the season pass is the better option

A function is a relationship that each input (element of the domain) is paired with exactly one output (element in the range).

In function notation, f(x), the “x” is the input and the entire “f(x)” represents an output.
That means the last two options are wrong. They’re purposely switched up in what they say.

The correct answer is the second one, because that one is saying “each input will be paired with exactly one output.”
