D. 27

Step-by-step explanation:

First, we look at the exponents and for 3, 3 to the power of 2 is 3 times 3. The answer to that is 9. Next, we look at 2 to the power of 3. That is 2 times 2 times 2. That equals 8. 8 + 4 = 12. 12 * 9 = 108. The numerator is 108 so now we go to the bottom and 2 to the power of 2 is 2 times 2. So the denominator is 4. 108 divided by 4 is 27 and that's your answer!

Answer:The polygon has 18 sides.

Step-by-step explanation;since it is a straight line, we get 8x since they said that each interior angle is 8 times the exterior angleso it is 8x =x which is the exterior angle +180 degrees since it is a sraight line.

n:

Answer:

A) Each Interior Angle = 180 degrees - (360 / number sides)

B) Each Exterior Angle = 360 / number of sides

A) = 8 * B)

8 * 360 / # sides = 180 - (360 / #sides)

We'll call # sides as "n".

2,880 / n = [ 180 - (360 / n)]

2,880 = n * [ 180 -(360 / n)]

3,240 = 180n

180n = 3,240

n = 18 sides.

The polygon has 18 sides which is an octadecagon.

Answer:

x = - 5

Step-by-step explanation:

The line with equation x = - 2 is a vertical line parallel to the y- axis.

A parallel line will also have the equation

x = c

where c is the value opf the x- coordinates the line passes through.

The line passes through (- 5, 4) with x- coordinate - 5, thus

x = - 5 ← equation of parallel line

Answer:

Volume of the liquid left in the container will be 80 ml.

Step-by-step explanation:

Two containers A and B having equal volumes of the liquid has been shown in the figure attached.

Let the volume of the liquid in each container = x ml

120 ml of the liquid was poured in container B from container A.

Volume of liquid in container B = 4 × Volume of the liquid in container A

x + 120 = 4(x - 120)

x + 120 = 4x - 480

4x - x = 480 + 120

3x = 600

x = 200 ml

Volume of the liquid left in container A = 200 - 120

                                                                    = 80 ml

Therefore, volume of the liquid left in the container A will be 80 ml.

Answers:

OQ + QP = OP

OQ = 11

============================================================

Explanation:

The smaller pieces OQ and QP glue together to form the larger segment OP. This is effectively what the Segment Addition Postulate says. This only works if all three points are on the same single line segment.

We know that OP is 17, so QP = 6 adds to the other unknown piece to get 17. The other piece must be 11 units long. Algebraically you could write,

OQ + QP = OP

OQ + 6 = 17

OQ + 6-6 = 17-6 ... subtracting 6 from both sides

OQ = 11

OQ is 11 if OP=17 and QP=6. This is obtained by using Segment Addition Postulate.

If Q is between O and P, then OQ + QP = OP.

Given, OP=17 and QP=6

According to Segment Addition Postulate,

OQ + QP = OP

OQ + 6 = 17

OQ= 17-6 =11

OQ = 11

∴ OQ + QP =17 and OQ = 11

Hence the value of OQ is 11 when OP is 17 and QP is 6.

Answer:

C) Normal distribution

Step-by-step explanation:

We are supposed to find A distribution in which the mean, mode, and median are nearly equal

A) bimodal

Bimodal distribution is a statistical pattern in which the frequencies of values in a sample have two distinct peaks, even though parts of the distribution may overlap.

B) Flat

A flat distribution can be said either to have no tails, or to have short tails.

C) Normal

A distribution in which the mean, mode, and median are nearly equal is called a normal distribution

D)Skewed

A left-skewed, negative distribution will have the mean to the left of the median.

A right-skewed distribution will have the mean to the right of the median.

Hence Option C is true

Answer:

The area of triangle ABC is 16 times larger than the area of triangle DEF

Step-by-step explanation:

Step 1: Re-state the input

Given two triangles ABC and DEF are similar with ratio k.

Step 2: Derive the information

Suppose that the triangle ABC is k times larger than triangle DEF.

=> It means that all sides and heights of triangle ABC are k times larger than corresponding sides and heights of triangle DEF.

For example:

AB = k x DE

AC = k x DF

BC = k x EF

=> AB + AC + BC = k x (DE + DF + EF)

=> Perimeter of triangle ABC is k times larger than perimeter of triangle DEF

Step 3: Solve the problem step-by-step

Suppose that AH is the height from vertex A to base BC of triangle ABC and DH' is the height from the vertex D to base EF of triangle DEF.

As the above assumption states:

AH = k x DH'

BC = k x EF

Multiply both sides of the two above equations:

=> AH x BC = DH x EF x k x k

Simplify k components:

=> AH x BC = DH x EF x k^2

Multiply (1/2) to both sides:

=> (1/2) x AH x BC = (1/2) x DH x EF x k^2

Apply the formula to calculate the area of a triangle:

=> Area of triangle ABC = Area of triangle DEF x k^2

In other words:

The area of triangle ABC is (k^2) times larger than area of triangle DEK.

Here, the perimeter of triangle ABC is 4 times larger than the perimeter of triangle DEF => k = 4

Step 4: Make the conclusion

=>The area of triangle ABC is (4^2 = 16) times larger than area of triangle DEK.

Answer: equilateral y=60

Step-by-step explanation:

The sum of all the angles in a triangle add up to 180 degrees. So, because you have the angle measurement of two sides, you can set up an equation to solve for the third side: 60+60+x=180 (do the math and you end up with y=60)

And because all three of the angle measures are equal, the triangle is defined as an equilateral triangle.

The value of y is 60° and the given triangle is Equilateral.

A triangle is a two dimensional figure which consist of three vertices, three edges and three angles.

We have a triangle where one of the angle is unknown.

Sum of the interior angles of a triangle is 180 degrees.

60° + 60° + y° = 180°

120° + y° = 180°

y° = 180° - 120°

y° = 60°

Equilateral triangles are those triangles whose all sides and all angles are equal.

Isosceles triangles are those whose 2 sides or 2 angles are equal.

Since all angles are equal to 60° here, this is an equilateral triangle.

Hence the given triangle is an equilateral triangle with the unknown angle equals 60°.

Answer:

the length of the radius of the Earth Model = 9cm

Step-by-step explanation:

The volume of the model of Earth is approximately 3052.08 cubic centimeters.

It has been discovered that the Earth is spherical in shape, hence this model is spherical as well.

The formula for the Volume of a Sphere = 4/3 πr³

Where r = radius or the length of the radius

The Volume of the Earth Model = 3052.08 cm³

We are told to use π = 3.14

To find the length of the radius, we have derive the formula

V = 4/3 × π × r³

V = 4πr³/3

Cross multiply

3V = 4πr³

Divide both side by 4π

3V/4π = r³

We find the cube root of both sides =

∛(3V/4π) = r

Substituting our given values in the question, we have:

∛(3 × 3052.08/ 4 ×3.14) = r

r = ∛9156.24÷12.56

r = ∛729

r = 9cm

Therefore, the length of the radius of the Earth Model = 9cm

Step-by-step explanation: The point-slope form is [tex]y_[/tex]-[tex]y_{1}[/tex]=[tex]m_[/tex]([tex]x_[/tex]-[tex]x_{1}[/tex])

In slope-intercept form, the equation would be y = -7x + 11

You could find the slope by using the slope equation, [tex]\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex].

Using that, you would get -7. Thus by inserting one of the points and the slope in the point-slope equation, you will get your answer.
