hello:) I need help with this. Thanks!

Answer:

432

Step-by-step explanation:

Volume of cuboid:

12 x 4.5 x 5.5 = 297

volume of traingular prism:

(12x5)/2 x 4.5 =135

add them together:

135+297 =432

hope this helps!

So, the required volume of the given wooden block is 432 cubic cm.

The formula for the volume of the rectangular prism is,

[tex]v=l\times b \times h[/tex]

And the formula for the volume of the triangular prism is,

[tex]v=\frac{1}{2} \times b \times h[/tex]

It is given that,

The volume of the wood is equal to the volume of the rectangular prism and triangular prism.

So, by using the above formula we can write as,

The volume of the wood is,

= volume of the wood is equal to the volume of the rectangular prism + triangular prism.

[tex]=l\times b\times h+\frac{1}{2}\times h\times l\\ =12\times 4.5 \times 5.5 +\frac{1}{2} \times 12\times 4.5 \times 5\\=297+135\\=432 cm^3[/tex]

Answer:

The Answer is D

Step-by-step explanation:

None of the prepositional phrases in the paragraph modify an adverb. They either modify a noun or a verb.

In understanding this question, a prepositional phrase is a group of words consisting of a preposition, its object, and any words that modify the object. On the other hand, a adverb is a word that modifies a verb, an adjective, or another adverb.

The prepositional phrases in the paragraph include 'in the movies,' 'for every actor,' 'on the movie set,' and 'of the latest technology.'

Examining these closely, it is easy to see that none of these prepositional phrases modify an adverb—they either modify a noun or a verb. Therefore, there are no prepositional phrases in this paragraph that modify an adverb.

Answer:

A) 288 [tex]cm^{3\\}[/tex]

Step-by-step explanation:

The Volume of the figure is 288 cm³.

Volume is a three-dimensional quantity used to calculate a solid shape's capacity. That means that the volume of a closed form determines how much three-dimensional space it can fill.

Given:

Base edges = 4 cm x 4 cm

Height = 1 cm

So, Volume = area of the base x height

For Figure 1:

Volume of figure1

=(4x4)x 10

=160

For Figure 2:

Volume of figure 2

= (8x4) x 4

= 128

Thus, the Total volume = 160+ 128 =288 cm³

Answer:10.35 dollars

Step-by-step explanation: 15% of 9 dollars is 1.35

so you add 1.35 to 9 dollars to find the total cost

The total cost she will have to pay for the toy is $10.35.

A percentage is a figure or ratio that can be stated as a fraction of 100. If we need to calculate the percentage of a number, we must divide it by its full value and then multiply it by 100. As a result, the percentage is one part in one hundred. "Per 100" is short for "per percent." It is represented by the symbol "%".

Given the cost of the toy = $9

sale tax on toy = 15% of the total price

sale tax on toy = 15% of 9

sale tax on toy =  0.15 x 9

sale tax on toy = $1.35

total  cost to pay = $9 + $1.35

total  cost to pay = $10.35

Hence total cost to pay is $10.35.

r = 10

Step-by-step explanation:

C = 62.8 = 2π·r

62.8 = 2·3.14·r

r = 62.8/2·3.14

= 31.4/3.14

= 10

Answer:

10 miles

Step-by-step explanation:

The circumference of a circle can be found using:

[tex]c=2r\pi[/tex]

We know circumference is 62.8, so we can substitute it in

62.8=[tex]2r\pi[/tex]

We want to find r, so we have to isolate it.

Divide both sides by [tex]2\pi[/tex] or 2*3.14 which is 6.28

62.8=[tex]2r\pi[/tex]

62.8=6.28r

62.8/6.28=6.28r/6.28

r=10

So, the radius is 10 miles

Answer:

47.1

Step-by-step explanation:

Sorry if its wrong

The cone's volume is approximately 47.1 cubic centimeters, obtained by rotating the provided isosceles triangle along its central blue axis.

The volume of a cone is calculated by the following formula:

[tex]$V = \frac{1}{3}\pi r^2 h$[/tex]

where r is the radius of the base and h is the height of the cone.

In this case, the height is simply the height of the triangle, which is 5 cm.

The radius is a bit trickier.  

Notice that the blue dashed line bisects the base of the triangle.  Therefore, the radius is half the length of the base, which is 6 cm / 2 = 3 cm.

Substituting these values into the formula, we get:

[tex]$V = \frac{1}{3}\pi (3\text{ cm})^2 (5\text{ cm})$[/tex]

[tex]$V = 15\pi \text{ cm}^3$[/tex]

Rounding this to the nearest tenth, we get:

[tex]$V = 47.1 \text{ cm}^3$[/tex]

Therefore, the volume of the cone is approximately 47.1 cubic centimeters.

Answer:

Step-by-step explanation:

XY=ST/2

3z+2=(7z-1)/2

2*(3z+2)=7z-1

2*3z+2*2=7z-1

6z+4=7z-1

+1         +1

6z+5=7z

-6z      -6z

5=z

The required value of z is 5.

Given that,

In RST, X is the midpoint of RS,

And Y is the midpoint of RT.

XY = 3z + 2 and ST = 7z - 1.

We have to determine,

What is the value of z.

According to the question,

X is the midpoint of RS,

And Y is the midpoint of RT.

Therefore,

[tex]XY = \frac{ST}{2}[/tex]

Putting the value of XY and ST in the equation,

XY = 3z + 2 and ST = 7z - 1.

Then,

[tex]XY = \frac{RS}{2} \\\\3z+ 2 = \frac{7z-1}{2}\\\\2 \times(3z+2) = 7z-1\\\\= 6z+4= 7z-1\\\\6z-7z = -1-4\\\\-z = -5\\\\= z = 5[/tex]

Answer:

105 degrees

Step-by-step explanation:

The sum of the angles in a triangle add up to 180. Although we don't the know the numerical values of the angles, we can create an equation with the given expressions:

<P + <Q + <R = 180

(6x + 5) + (11x - 5) + x = 180

18x = 180

x = 10

Now, plug this value of x into the expression for Q:

<Q = 11x - 5 = 11 * 10 - 5 = 110 - 5 = 105

Thus, the measure of angle Q is 105 degrees.

Hope this helps!

Answer:

105 degrees

Step-by-step explanation:

The angles in a triangle must add to 180 degrees

<Q +<P + <R =180

We know <Q is 11x-5, <P is 6x+5 and <R is x, so we can substitute them in

11x-5+6x+5+x=180

Combine like terms

11x+6x+x +5 -5 =180

18x=180

Divide both sides by 18

x=10

Now we know x, and we can substitute that in to to find <Q

<Q=11x-5

<Q=11(10)-5

<Q=110-5

<Q=105
