Answer:

the answer is 14.3

Step-by-step explanation:

The height of the trapezoidal prism is 12.3 feet.

[tex]v = \frac{1}{2}(b_{1} +b_{2} )hl[/tex]

where,

v is the volume of trapezoidal prism

[tex]b_{1}[/tex] and [tex]b_{2}[/tex] are the bases

h is the height of trapezoidal prism

l is length of the trapezoidal prism

According to the given question

We have to find the value of x which is the length of trapezoidal prism.

And,

Volume, v = 464.75 cubic feet.

From the given figure

here,

[tex]b_{1} = 5ft[/tex], [tex]b_{2} = 8ft[/tex],  [tex]h = xft[/tex], and [tex]l = 5.8ft[/tex]

Substitute all these values in the formula of the volume of trapezoidal prism

⇒ 464.75 = [tex]\frac{1}{2}[/tex] ×(5+8)(5.8)x

⇒929.5 = 13×5.8x

⇒[tex]\frac{929.5}{(13)(5.8)}[/tex] = [tex]x[/tex]

⇒ x = 12.3 feet

Hence, the height of the 12.3 feet.

Answer:

m∠1= 31°  m∠2=149°

m∠3= 31° m∠4=149°

m∠6=31° m∠7=149°

m∠8=31°

Step-by-step explanation:

m∠1 + m∠5= 180°

m∠1=180-149

m∠1=31°

m∠2+m∠1=180

m∠2=149°

m∠6=31°

m∠3=m∠1 (corresponding angle)

m∠3=31° m∠8=31° (vertical angle)

m∠4=149° m∠7=149° (vertical angle)

Answer:

3262.9 cm^3

Step-by-step explanation:

Formula =

[tex] \frac{4}{3} \times \pi r ^{3} [/tex]

Pi = 3.145

So,

[tex] \frac{4}{3} \times 3.145 \times 9.2 ^{3} \\ = 3262.183595 \\ = 3262.9 cm^{3} [/tex]

Here you go

let's write 2*2*2*2*2*2*2*2*2 in exponential form.

Notice 2 has been multiplied times itself 9 times.

Basic exponential notation:-

[tex]\sf{2*2=2^2}[/tex]

[tex]\sf{2*2*2=2^3}[/tex]

[tex]\sf{2*2*2*2=2^4}[/tex]

You should notice a pattern.

This is the pattern:-

The number of times 2 has been multiplied times itself is the exponent.

In this case, we multiplied 2 times itself 9 times.

Hence, the answer is

[tex]\bigstar{\boxed{\pmb{2^9}}}[/tex]

Answer:

120 cubes are required.........

Answer:

120 1/3 cubes

Step-by-step explanation:

you have 5 thirds so 5 and 4 thirds so 4 and 2 wholes which is 6 thirds so you would multilpy them and the equation would be 5x4x6 and that equals 120.

Answer:

A. 12.25 tons

Step-by-step explanation:

We will let x represent the amount required to cover the entire wall.

We can divided 2/5 by 5/6 to solve for x

2/5 divided by 5/6=x

When you divide by a fraction, you can always multiply by the reciprocal (flipped number).

Our new equation is:

2/5·6/5=12/25

Answer: 35°

Step-by-step explanation:

m∠A + m∠B + m∠C  =  180°

40° + 105° + m∠C = 180°

m∠C + 145°  =  180°

Subtract 145° from both sides.

m∠C  =  35°

So, the measure of the missing angle (x) is 35°.

Answer:

The width of the scale model is 33 inches.

Step-by-step explanation:

This question is solved making a relation with the scale model. In the scale, 3 inches are worth 11 real feet.hope this help you.if you need any more help let me now and I mite be abal to help you.

The actual gallery comes to be 84 feet long.

A scale factor is a factor by which the dimension of an object is enlarged or diminished.

Scale of 2 inches = 7feet.

So, a scale of 1 inch = 7/2 feet

So, scale factor =7/2

So, a scale of 24 inches = 24*scale factor= 24*7/2 = 84 feet

So, the actual length of the gallery = 84 feet

Therefore, the actual gallery comes to be 84 feet long.
