2. If Hardy fills the box completely with the least number of layers, there will be (blank) books on the bottom layer.
3. To fill the box completely, Hardy places 8 layers of books in the box. There are (blank) books in each layer.

Thank you so much for help! Just a mom who hates volume trying to help her kid with volume.

Answer:

<u>1. 192 books.</u>

<u>2. 96 books.</u>

<u>3. 24 books.</u>

Step-by-step explanation:

1. Let's find the volume of each book and the volume of the box, this way:

Volume of a book = 4 * 6 * 1 = 24 inches ³

Volume of the box = 24 * 24 * 8 = 4,608 inches ³

2. If Hardy fills the box completely, what is the greatest number of books that fit into the box?

Greatest number of books = Volume of the box/Volume of a book

Greatest number of books = 4,608/24

<u>Greatest number of books = 192</u>

3. If Hardy fills the box completely with the least number of layers, there will be (blank) books on the bottom layer.

The height of the box is 8 inches, so it can only can hold 2 or 8 layers of books, since the books are 4 * 6 * 1 inches.

Greatest number of layers = Height of the box/Width of a book

Greatest number of layers = 8/1 = 8

Minimum number of layers = Height of the box/Height of a book

Minimum number of layers = 8/4 = 2

Upon saying that, we have:

Number of books per layer = Greatest number of books/Minimum number of layers

<u>Number of books per layer = 192/2 = 96 </u>

4. To fill the box completely, Hardy places 8 layers of books in the box. There are (blank) books in each layer.

Number of books per layer = Greatest number of books/Number of layers

Number of books per layer = 192/8

<u> Number of books per layer = 24</u>

What is an equation of the line, in point slope for, that passes though the given point and has the given slope? point:(7,3);slo
Airida [17]

Answer:

The equation of this line is y - 3 = 4/7(x - 7)

Step-by-step explanation:

To find this, start with the base form of point-slope form.

y - y1 = m(x - x1)

Now put the slope in for m and the two coordinates in for (x1, y1).

y - 3 = 4/7(x - 7)

Deffense [45]

Answer:

1.4 hour, or 1 hr 24 min

Step-by-step explanation:

The trains separate at the rate (80 + 90) mph.

Recall that distance = rate times time, or time = distance / rate.

                                            238 mi

Here, the elapsed time is  -------------- = 1.4 hr, or 1 hr 24 min

                                             170 mph

For this exmaple, x is the one increasing by a third power for every y

Logarithmic is the opposite of exponential

Exponential is when y is the one increasing by a power for every x.

Therefore this one is logarithmic.

The sum of the measures of the interior angles of a convex polygon is 3960°.
scZoUnD [109]

Step-by-step explanation:

The sum of the interior angles of a convex regular polygon is 180 times (n-2), where n is the number of sides. Since we already know the sum, we can write 3,960 = 180(n-2). If you solve for n in this equation, you will have the number of sides.
