Tamara stacked two cubes, as shown. 2 stacked cubed. One cube has side lengths of 24 inches, and the second cube has side lengths of 12 inches. What is the total volume of the cubes? 1st cube volume: V = Bh V = (12)(12)(12) 2nd cube volume V = Bh V = (24)(24)(24) The total volume of the cubes is cubic inches.

Answers

Answer:

15 552 in³

Step-by-step explanation:

Since cubes have the same side lengths all around, to find the volume, you need to have one side length and cube it.

Cube 1 : 24³ = 24 x 24 x 24 = 13 824 in³

Cube 2 : 12³ = 12 x 12 x 12 = 1 728 in³

Now, to find the total, just add the volumes.

13 824 + 1 728 = 15 552 in³

The total volume of the cubes is V = 15,552 cubic inches

What is the Volume of a Cube?

The formula of volume of the cube is given by:

Volume of Cube = a x a x a

Volume of Cube = a³

where a is the length of its sides or edges

Given data ,

The volume of the first cube with side length of 24 inches is given by:

V1 = (24 inches)³ = 13,824 cubic inches

The volume of the second cube with side length of 12 inches is given by:

V2 = (12 inches)³ = 1,728 cubic inches

The total volume of the two cubes is the sum of their volumes:

Total volume = V1 + V2 = 13,824 + 1,728 = 15,552 cubic inches

Hence , the total volume of the cubes is 15,552 cubic inches

Kelly bought 3 bracelets and 4 necklaces. She spent between $39 and $59. Each bracelet costs the same amount. Each necklace costs the same amount. The price of a bracelet is $5. How many dollars was the necklace?

Answers

Answer:

1 necklace will therefore cost 34/4 = $8.5

Step-by-step explanation:

She spent between $39 and $59. let us find the average of the amount she spent = 39+59 / 2 = $49.

At an average, she spent $49.

The price of a bracelet is $5 and each bracelet costs the same amount and she bought 3 bracelets = $5 x 3 bracelets each = $15... She spent $15 on the bracelets.

Thus $49 - $15 = amount spent on the 4 necklaces = $34.

4 necklaces cost $34, 1 necklace will therefore cost 34/4 = $8.5

Huixian needs 171 pens , 63 pencils and 27 erasers into identical gift bags so that each item is equally distrusted among the gift bags . Find the number of each item in a gift bag

Answers

Answer:

57 pens per bag

21 pencils per bag

9 erasers per bag

Step-by-step explanation:

Here, we are to distribute a specific portion of each of the items in each of the gift bags.

What we must take into consideration is that the number of items per gift bag must be equal.

Thus, what we do is to divide the total number of each item by 3 to get exactly the number of each items that would be in each of the gift bags

For the pens, we have 171/3 = 57 pens per bag

For the pencils, we have 63/3 = 21 pencils per bag

For the erasers, we have 27/3 = 9 erasers per bag

Calculate the value of sin X to four decimal places

Answers

Answer:

0.7241

Step-by-step explanation:

sin = [tex]\frac{opposite}{hypotenuse}[/tex]

In this case we have the hypotenuse (2.9) but not the opposite so here is how you calculate it

[tex]a^{2}+b^{2}= c^{2} \\\\2^{2}+ b^{2}= 2.9^{2} \\4+ b^{2} = 8.41\\\\\sqrt{b^{2} }= \sqrt{4.41} \\b= 2.1[/tex]

So now you have the opposite (2.1)

so now you would divide [tex]\frac{2.1}{2.9} or 0.7241[/tex]

Answer:

[tex] \sin X = 0.7241 [/tex]

Step-by-step explanation:

For angle X, 2.0 ft is the adjacent leg. 2.9 ft is the hypotenuse.

The trig ratio that relates the adjacent leg to the hypotenuse is the cosine.

[tex] \cos X = \dfrac{adj}{opp} [/tex]

[tex] \cos X = \dfrac{2.0}{2.9} [/tex]

[tex] \cos X = 0.689655 [/tex]

Since we now know the value of cos X, we can find the value of sin X by using the trig identity

[tex] \sin^2 X + \cos^2 X = 1 [/tex]

[tex] \sin^2 X + (0.689655)^2 = 1 [/tex]

[tex] \sin^2 X = 0.524376 [/tex]

[tex] \sin X = 0.7241 [/tex]

Kayla is going to tile a 6 foot by 9 foot rectangular section of her bathroom wall with square tiles that measure 3 inches tall and 3 inches wide. How many tiles will she need for her project?

Answers

Answer: 864 tiles

Step-by-step explanation:

Rather than calculating the whole area of bathroom and area of one tile, It is quicker and easier to determine how many rows of tiles that will be needed.

Note that 1 feet = 12 inches

Each tile measures 3 inches on each side.

Length: 9 feet = 9 × 12 = 108 inches

Therefore, 108/3 = 36 tiles will fit along the length.

Width: 6 feet = 6 × 12 = 72 inches. Therefore, 72/3 = 24 tiles will fit along the width.

So, (36 × 24) = 864 tiles will be needed.

Step-by-step explanation:

Answer:

942.4777961 or 942

Step-by-step explanation:

First find the area of the circle using \pi r^{2} . Radius is half of diameter so the radius is 10.

\pi 10^{2} = 314.1592654

Then multiply the depth to the area of the circle.

During the first few years of a tree's life, its growth rate is linear. For example, an oak tree grows at a rate of 1.5 feet per year for the first twelve years. Mostafa plants a maple tree in his backyard and measures its height at 4 feet. Two years later, Mostafa measures the tree again and finds that its height is now 6.5 feet. Which statement is correct given this information?

Answers

Answer:

Mostafa's maple tree grows at a slower yearly rate than an oak tree.

Step-by-step explanation:

Given that:

An oak tree grows at a rate of 1.5 feet per year for twelve years;

After 12 year; the oak tree will be = 12 × 1.5 = 18 feet per year.

Now; we are being told that Mostafa plants a maple tree at his backyard and measures its height at 4 feet.

i.e x years  = 4 ft

two years later ; it height is now 6.5 ft

thus;

x year = 4 ft

x + 2 = 6.5 ft

[tex]6.5 * x = (x+2)4\\ \\ 6.5 x = 4x + 8\\ \\ 6.5x-4x = 8\\ \\ 2.5x = 8\\ \\ x = \dfrac{8}{2.5}\\ \\ x = 3.2[/tex]

Thus ; Mostafa first measured the height of the tree when it is 4 ft at the age year of  3.2

So;

if 3.2 year = 4 ft

1 year = x

x  = [tex]\dfrac{4 *1 }{3.2}[/tex]

x  = 1.25 ft

So if an oak tree grows at the rate of 1.5 ft in a year.

Then, Mostafa's maple tree grows at the rate of 1.25 ft in a year.

From the given information in the diagram attached below; we can infer that :

Mostafa's maple tree grows at a slower yearly rate than an oak tree.

Ellen "The Wonderer" continues to walk in the path of an inscribed polygon. She starts at W, walks south until the boundary point E, turns 70 degrees and walks east till S, turns 100 degrees, and walks north to point T. Determine how many degrees Ellen must turn to get back to her starting point.

Answers

Answer:

110°

Step-by-step explanation:

The path in the inscribed polygon walked by Ellen is shown in the diagram attached. Let the degrees in which Ellen must turn to get back to her starting point be T. Therefore to calculate T we use the theorem "An inscribed quadrilateral whose vertices all lie on a circle, the opposite angles of such a quadrilateral are in fact supplements for each other i.e their sum is 180 degrees."

Therefore: T + 70° = 180°

T = 180° - 70°

T = 110°

To get back to the starting point, Ellen must turn 110°
