Answer:

A) 40

B) 20

Step-by-step explanation:

By <em>Length · Width · Height</em>

A)  (5) · (4) · (2) = 40

For part B, the length and width are the same, but the depth (height) of the water is only one foot, so we can replace the height value from the first equation with 1.

For the scientific notation, write the standard form: 5.61 x 102
Alekssandra [29.7K]

<em>I believe the exponential form above is 5.61 x </em>10^{2}

Answer:

561

Step-by-step explanation:

A<em> "scientific notation"</em> is being used in order to express large numbers in its <u>simplest form</u>. This is commonly used in careers that use Mathematics very often like<em> engineers</em> or<em> scientists </em>because it makes their computation easier.

The<em> "standard form"</em> refers to the standard or traditional way of writing the numbers.

In order to get the standard form above, you have to check the <em>"power of the number 10." </em>The exponent above is 2. This means that you have to move the decimal point of 5.61 to the<em> right twice.</em> So, the answer is 561.

How many quart are 8/1/4 gallons
Westkost [7]

Given:

Consider the given gallons are 8\dfrac{1}{4} gallons.

To find:

The number of quarts in 8\dfrac{1}{4} gallons.

Solution:

We know that,

1 gallons = 4 quarts

Using this conversion, we get

8\dfrac{1}{4}\text{ gallons}=4\times 8\dfrac{1}{4}\text{ quarts}

8\dfrac{1}{4}\text{ gallons}=4\times \dfrac{32+1}{4}\text{ quarts}

8\dfrac{1}{4}\text{ gallons}=4\times \dfrac{33}{4}\text{ quarts}

8\dfrac{1}{4}\text{ gallons}=33\text{ quarts}

Therefore, there are 33 quarts in 8\dfrac{1}{4} gallons.
