Answer:

1. 192 books.

2. 96 books.

3. 24 books.

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

Greatest number of books = 192

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

Number of books per layer = 192/2 = 96

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

Number of books per layer = 24

Answer: 5/6

Step-by-step explanation:

All we need do is to try to change 50 minutes to hour.

Remember that 60 minutes make 1 hour , so we need to find 50 minutes out of 1 hour , that is 50 minutes out of 60 minutes. Which is 50/60. Therefore:

50 minutes is 50/60 fraction of an hour

50/ 60 is the same as 5/6 in reduced form

Answer:

Step-by-step explanation:

1hour is 60minutes

= 50/60

Explanation:

For reasons unknown, Brainly gets bent by the use of "f(x)". So, an appropriate answer cannot be posted as text. I have posted it as attached pictures.

The expression f(f^-1(x)) represents the composition of a function and its inverse, which always returns the original input x.

The expression f(f^-1(x)) involves the composition of a function and its inverse. A function composed with its inverse will always yield the original input, this property is fundamental in the concept of inverse functions. So f(f^-1(x)) will equal x in all and every case.

The reason why this is the case can be visualized by the definition of an inverse function. Given a function f(x), the inverse function f^-1(x), by definition, undoes the operation of f(x). This means that, if we apply f(x) and then apply f^-1(x), we will come back to our starting point.

Answer: He needs 3 stripes.

Final answer:

To cover the perimeter of a 14 feet by 10 feet room, Jim will need 3 strips of wallpaper border as the total perimeter is 48 feet and each wallpaper strip is 20 feet long.

Explanation:

To determine how many strips of wallpaper border Jim will need for his rectangular room, we need to calculate the total perimeter of the room. The formula for the perimeter of a rectangle is:

Perimeter = 2 × (Length + Width)

For Jim's room:

Perimeter = 2 × (14 feet + 10 feet)

Perimeter = 2 × 24 feet

Perimeter = 48 feet

Now, we know each strip of wallpaper is 20 feet long, so we divide the total perimeter by the length of one strip:

Number of strips needed = Total Perimeter ÷ Length of one strip

Number of strips needed = 48 feet ÷ 20 feet

Number of strips needed = 2.4

Since Jim cannot purchase a fraction of a strip, he will need to buy 3 strips of wallpaper border to cover the entire perimeter of his room.

Note: It's assumed that there's no significant wastage when the wallpaper strips are applied, and the strips are used efficiently.

Step-by-step explanation:

By leaf plot...

==============================================================

Explanation:

The first row has a stem of 1 and a leaf of 6. The stem and leaf combines to 16. For this problem, the stem will always be the tens digit while the leaf values will be the units digit. If there are multiple leaves for a given row, then we use the same stem value.

In row 2, we have "2" as the stem and multiple leaves. The first three leaves for this row are {2, 2, 5}. They pair up with the stem to form the values 22, 22, 25.

So far the data set is 16, 22, 22, 25. Only choice C has this sequence of values at the start of it. Choice B comes close, but it does not have a second copy of 22. So we cross choice B off the list. Choice D is off the list because the first value '5' is not represented on the stem and leaf plot (the stem would be 0 to represent the value 05 which is just 5). Choice A is false for similar reasons.

Answer:

The correct option is last one  77 degrees.

Therefore the measure angle W is 77 degrees.

Step-by-step explanation:

Given:

Exterior angle = 122°

∠W = (2x-13)°

∠Y= x°

To Find:

∠W = (2x-13)° = ?

Solution:

Exterior Angle Property:

An exterior angle of a triangle is equal to the sum of the opposite interior angles.

Angle W and Angle Y are the interior angles of Exterior angle 122°.

∴ [tex]Exterior\ angle=m\angle W+m\angle Y[/tex]

Substituting the values we get

[tex]122=2x-13+x\\3x=135\\\\x=\dfrac{135}{3}=45\\\\x=45[/tex]

Now Substitute 'x' in angle W we get

[tex]m\angle W=2\times 45 -13=77\°[/tex]

Therefore the measure angle W is 77 degrees.

77 is the answer

[tex]2\frac{3}{4}+3 \frac{5}{8}=6\frac{3}{8}[/tex]

Solution:

Given expression is [tex]2\frac{3}{4}+3 \frac{5}{8}[/tex].

To simplify the expression [tex]2\frac{3}{4}+3 \frac{5}{8}.[/tex]

Let us first convert the mixed fraction into improper fraction.

[tex]2\frac{3}{4}+3 \frac{5}{8}=\frac{(2\times 4) + 3}{4}+ \frac{(3 \times 8)+5}{8}[/tex]

            [tex]=\frac{8+ 3}{4}+ \frac{24+5}{8}[/tex]

            [tex]=\frac{11}{4}+ \frac{29}{8}[/tex]

Take LCM for the denominators (LCM of 4, 8 = 8) and make the same.

            [tex]=\frac{11\times2}{4\times 2}+ \frac{29\times1}{8\times1}[/tex]

            [tex]=\frac{22}{8}+ \frac{29}{8}[/tex]

            [tex]=\frac{51}{8}[/tex]

Now, divide 51 by 8 and again write it in the mixed fraction.

             [tex]=6\frac{3}{8}[/tex]

[tex]2\frac{3}{4}+3 \frac{5}{8}=6\frac{3}{8}[/tex]

Hence, the simplified answer is [tex]6\frac{3}{8}[/tex].

y = x - 6

to find the inverse, switch x and y and solve for y

x = y - 6

x + 6 = y...rearrange

y = x + 6 <== ur inverse

The inverse of the equation y = x - 6 is achieved by swapping x and y and then solving for y. This results in the equation y = x + 6, which is the inverse function.

The function that is the inverse of y = x - 6 can be found by switching the x and y in the equation, then solving for y. By performing this operation:

1. Switch x and y: x = y - 6

2. Solve for y: y = x + 6

Therefore, the inverse function of y = x - 6 is y = x + 6.

Answer:

72 feet is the answer. The shadow of the 63 ft tower.

To find the shadow length of a 63-foot building given a 7-foot stop sign's 8-foot shadow, a proportion is used, resulting in a shadow length of 72 feet.

A student asked how to find the length of the shadow cast by a 63-foot tall building given that a 7-foot tall stop sign casts an 8-foot long shadow. This problem can be solved using simple proportions since the ratio of the height of an object to the length of its shadow is constant when the sun's angle is constant. The proportion is as follows: height of stop sign / length of stop sign's shadow = height of building / length of building's shadow. Plugging in the numbers: 7 / 8 = 63 / x, where x is the length of the building's shadow. Solving for x, we find that x = 8 * 63 / 7 = 72. Therefore, the length of the shadow cast by the 63-foot tall building is 72 feet.
