Answer:

105  \: {yd}^{3}

Step-by-step explanation:

The formula to find the volume of a triangular prism is:

\frac{1}{2} base \:  \times \: height \:  \times length

Therefore we say:

\frac{1}{2} (7) \times 5 \times6 \\  = 3.5 \times 5 \times 6 \\  = 105 \: {yd}^{3}

The answer is 34 2/3. To find this you first find the area of the base which is (length x width) divided by 2 which in this case equals 21, then you multiply the base area by the height, 21 x 5, which equals 105, and last you divide that by 3 or multipy by 1/3, so 105/3 equals 34.999 which is can be written in fraction form as 34 2/3

Hope this helps, also sorry if my explanation is confusing

\large \mathfrak{Solution : }

let's write the given equation in its slope intercept form :

i.e y = 6x + 8

by comparing to the general equation : y = mx + c

we get, slope (m) = 6

Need help. Anything is appreciated!
Lynna [10]

First attatchment:

1. Given

2. Definition of a parrallelogram

3. Transitive

4. Parts of line FE and AB

5. Opposite sides of a parallelogram are parallel.

You want to switch those last two because you're using what you want to prove to prove something before you've proved it, which is fallacious.

SECOND ATTATCHMENT:

In a parallelogram, opposite angles are equal and same side interior angles add up to 180.We have 2x+60+x+30=180 which means 3x+90=180 so x=30.Since x is 30 then angle to is 60 which means that angle A is 60, not 30.

THIRD ATTATCHMENT:

This is just the triangle midpoint theorem. SM is parallel to RU not VS.

FOURTH ATTATCHMENT:

Angle X and angle F are corresponding angles, so they are actually equal. You want Angle G and Angle F becuase they are same side interior angles.

FIFTH ATTATCHMENT:

this is correct

Which expression is equivalent to 144 Superscript three-halves? 216 1,728 RootIndex 3 StartRoot 12 EndRoot RootIndex 3 StartRoot
Afina-wow [57]

Question:

Which expression is equivalent to 144^(3/2)

Answer:

1728

Step-by-step explanation:

The options are not well presented. However, this is the solution to the question.

Given:

144^(3/2)

Required:

Find Equivalent.

We start my making use of the following law of logarithm.

A^(m/n) = (A^m)^1/n

So,

144^(3/2) = (144³)^½

Another law of indices is that

A^½ = √A

So,

144^(3/2) = (144³)^½ = √(144³)

144³ can be expanded as 144 * 144 * 144.

This gives

144^(3/2) = √(144 * 144 * 144)

The square root can then be splitted to

144^(3/2) = √144 * √144 * √144

144^(3/2) = 12 * 12 * 12

144^(3/2) = 1728.

Hence, the equivalent of 144^(3/2) is 1728
