Step-by-step explanation:

v = 1/3* L * w * h

1024 = 1/3 * 16 * 16 * height

1024 = 85.3333333 * height

divide both sides by 85.3 to isolate height = 12 cm

check your work

1024 = 1/3 * 16 * 16 * 12

1024 = 1024

yes they equal so its correct

The cost of a full-length mirror when the cpi is 211 is $187.68. Then the correct option is C.

A ratio is an ordered couple of numbers a and b, written as a/b where b can not equal 0. A proportion is an equation in which two ratios are set equal to each other.

The cell phone plan is an illustration of a linear inequality

Adrian gigabyte usage must be less than 2.1 to spend under $70.

The given parameters are:

Base cost = $59.50

Rate = $5 per gigabyte

Let the number of gigabyte be x.

So, the total amount is:

Total = 59.50 + 5x

Adrian wants to spend under $70.

So, we have:

59.50 + 5x < 70

Evaluate the like terms

5x < 10.5

Divide both sides by 5

x < 2.1

Hence, the number of gigabyte must be less than 2.1

Combined surface area for the 8 prisms is: 3,040 square centimeters.

3,500 cm² > 3,040 cm², therefore, Sasha has enough cloth for the design.

Surface area = (b1 + b2)h + PH

Given the following dimensions:

Plug in the values into SA = (b1 + b2)h + PH:

Surface area = (5 + 15)7 + (40)(6)

Surface area = 380 sq. cm.

Combined surface area for the 8 prisms = 380 × 8 = 3,040 square centimeters.

Step-by-step explanation:

7 + 6 = 13                (Length + Height)

13 x 5 = 65              side a (h + l)

15 x 13 = 195           side b (h+l)

10 x 6 = 60             side c x length

Solving

Answer:

x=-2

Step-by-step explanation:

Hey there!

In order to solve this equation, you need to combine like terms

The equation after combining the x terms and the contants will look like this

10x+3=12x+7

Now you have to take 10x away from both sides

3=2x+7

Now bring all the constants to the left side

3-7=2x

Simplify

-4=2x

divide 2 on both sides to get x by itself

x=-2

So, the answer is x=-2

Answer:

30% also means 30/100 in fraction form.

(Think of the root 'per' in percent to be per a 100.)

The keyword 'of' means multiplication.

'X' will be the unknown number aka the part that says ('-what number').

And 123 will represent the result.

Set up equation;

Then solve for x;

So your answer is 410.

Answer:

25

Step-by-step explanation:

These angles are supplementary, or add up to = 180 degrees:

(2x + 10) + (4x + 20) = 180

6x + 30 = 180

6x = 150

x = 25

Let's check our work:

2(25) + 10 = 60

4(25) + 20 = 120

60 + 120 = 180 degrees :)

Good luck!

Answer:

? = 4

Step-by-step explanation:

2/13 + ?/13 = 6/13        (Given)

-2/13               -2/13      (Isolate the unknown through subtraction)

?/13 = 6/13 - 2/13        

?/13 = 4/13                    (Combine like terms)

? = 4

Because the demoninators are the same, the unknown value can be found using isolation techniques. To find the unknown, subtract 2/13 from both sides. This eliminates the 2/13 from the right side while obeying the rule that states that what is done to one side must to done to the other. This leaves the ?/13 by itself on the right and 4/13 on the left. Again, because the demoninators are identical, the unknown value must be 4.

Answer:

(-12, -2)

Step-by-step explanation:

Rearrange the equation --> x^2 + 14x + 24 = 0

Split 14x into 12x + 2x --> x^2 + 12x + 2x + 24 = 0

Group --> x(x + 12) + 2(x + 12) = 0, (x + 12)(x + 2) = 0

Find roots:

x + 12 = 0, x = -12

x + 2 = 0, x = -2

The solution of the given expression [tex]\rm x^{2} +14x = -24\\[/tex] by completing the square method is 12 and  -2.

The given expression is

[tex]\rm x^{2} +14x = -24\\[/tex]

In completing the square, we take half of the coefficient of the middle term and then square it. Then we add it to both sides of the equation

Here coefficient of middle term x is +14.

So, 14/2 = 7

square of 7 is 49

[tex]\rm x^{2} +14x +49= -24+49\\\rm (x+7) (x+7)=25\\\rm (x+7)^{2} =5^{2} \\\rm x+7 =5[/tex]

x+7 = 5 and x+7 = -5

Solve for x by subtracting 7 on both sides

x = -2  and x= -12

Solution set is {-12, -2}
