Well well we find the area of the triangle first:
area = 1/2 * base * height
area = 1/2 * 8 1/4 * 5 3/4
area = 1/2 * 33/4 * 23/4
area = 1/2 * 759/16
area = 759 / 32
area = 23 23/32

now if we multiply the length of the triangles we get volume because the volume of the prism is really just the sum of the areas of all the triangles that make up it's length. So:
volume = 23 23/32 * 12
volume = 276 276/32
276/ 32 = 8 5/8
volume = 284 5/8

Sari wrote the equivalent ratios below to convert cups to fluid ounces. StartFraction 8 fluid ounces Over 1 cup EndFraction = St

Amiraneli [1.4K]

Answer:

(B)72 fluid ounces

Step-by-step explanation:

To convert cups to fluid ounces, Sari wrote the equivalent ratios.

$\dfrac{8 \text{ fluid ounces}}{1\text{ cup}} =\dfrac{\text{? fluid ounces}}{9\text{ cups}}$

Let the question mark be represented by x.

We then have:

$\dfrac{8 \text{ fluid ounces}}{1\text{ cup}} =\dfrac{\text{x fluid ounces}}{9\text{ cups}}\\$Cross multiply\\x \times 1 = 8 \times 9\\x=72$ fluid ounces$

We conclude that there are 72 fluid ounces in 9 cups.

dimaraw [331]

Answer:

First option.

Third option.

Fourth option.

Step-by-step explanation:

For this exercise is important to remember that equivalent expression have the same value.

Then given the following expression provided in the exercise:

$(5x)3$

You can find equivalent expression by:

- Changing the position of $3$ :

$3(5x)$ (This matches with the first option)

- Solving the multiplication indicated. Then:

$(5x)3=15x$ (This matches with the fourth option)

- Writting $x3$ inside the parentheses:

$5(x3)$ (This matches with the third option)

A shopkeeper sold 12 bags on the first day. The number became four times

dybincka [34]

The total number of the bags sold by the shopkeeper will be 65532.

<h3>What is number series?</h3>

The sequence formed by using the numbers is termed as the number series.So in this question from day one to day seven each day the sold items are multiplied by 4.

So the mathematical expression will be given as:

$=(12\times 4^0)+(12\times 4^1)+(12\times 4^2)+(12\times 4^3)+(12\times 4^4)+(12\times 4^5)+(12\times 4^6)$
