The central angle of a regular dodecagon is 30 degrees. Option A is the correct option.

The central angle - The angle created at the polygon's center by two adjacent radii—the lines that connect the polygon's center to its vertices—is known as the central angle.

We know it is a regular dodecagon, which means all the sides will be of equal size.

As it is a dodecagon there will be a total of 12 equal central angles added to give an angle of 360 degrees.

Let's assume the central angle is x.

12x = 360

x = 360/12

x = 30

Hence, the central angle in a regular dodecagon is 30 degrees.

Actually, 0 degrees is not a counterexample for the expression sin(y)*tan(y) = cos(y).

To see why, let's substitute y = 0 degrees into the expression:

sin(y)*tan(y) = cos(y)

sin(0)*tan(0) = cos(0)

0*tan(0) = 1

0 = 1

As we can see, the equation does not hold for y = 0 degrees. However, this does not make 0 degrees a counterexample, because 0 degrees is not in the domain of the tangent function.

The tangent function is undefined at odd multiples of 90 degrees (e.g. 90, 270, etc.), because at those angles the denominator of the tangent function becomes zero. Therefore, we cannot substitute y = 0 degrees into the expression sin(y)*tan(y) = cos(y), because it would result in division by zero.

In summary, 0 degrees is not a counterexample for the expression sin(y)*tan(y) = cos(y), because it is not in the domain of the tangent function.

Another expression to calculate the total amount spent would be (7+2) x 28.

This expression uses the distributive property, which states that when multiplying a number by a sum, the number can be multiplied by each addend separately and then the results can be added together.

In this case, we are multiplying 28 (the cost of the dresses and shoes) by the sum of 7 (the number of dresses bought) and 2 (the number of shoes bought). This would be the same as (7x28) + (2x28), which is the same as (7x28) (2x28). Therefore, the total amount Cindy spent is (7+2) x 28, which is equal to $392.

Answer:

The numbers are 36 and 68.

Step-by-step explanation:

Let the smaller number be x.

"The larger number is four less than two times the smaller

number."

The larger number is

2x - 4

The sum of the numbers is x + 2x - 4, or 3x - 4.

"The sum of the numbers is 104."

3x - 4 = 104

3x = 108

x = 36

The smaller number is 36.

The larger number is 2x - 4, or

2x - 4 = 2(36) - 4 = 72 - 4 = 68

The larger number is 68.

Answer: The numbers are 36 and 68.

The measure of arc BC is 720 times the measure of angle BAC.

Given that AC is the diameter of the circle and AB is a chord with a length of 16 units, we need to find BC (the length of the other chord) and mBC (the measure of angle BAC).

To find BC, we can use the property of chords in a circle. If two chords intersect within a circle, the products of their segments are equal. In this case, since AB = BC = 16 units, the product of their segments will be:

AB * BC = AC * CE

16 * BC = 2 * r * CE (AC is the diameter, so its length is twice the radius)

Since the area of the circle is given as 289 square units, we can find the radius (r) using the formula for the area of a circle:

Area = π * r^2

289 = π * r^2

r^2 = 289 / π

r = √(289 / π)

Now, we can substitute the known values into the equation for the product of the segments:

16 * BC = 2 * √(289 / π) * CEBC = (√(289 / π) * CE) / 8

To find mBC, we can use the properties of angles in a circle. The angle subtended by an arc at the center of a circle is double the angle subtended by the same arc at any point on the circumference. Since AC is a diameter, angle BAC is a right angle. Therefore, mBC will be half the measure of the arc BC.

mBC = 0.5 * m(arc BC)

To find the measure of the arc BC, we need to find its length. The length of an arc is determined by the ratio of the arc angle to the total angle of the circle (360 degrees). Since mBC is half the arc angle, we can write:

arc BC = (mBC / 0.5) * 360

arc BC = 720 * mBC

Therefore, the length of the arc BC equals 720 times the length of the angle BAC.

x = -1 and y = -13, (-1,-13) is the solution to the system of equation y = 3x - 10 and y = -2x - 15.

Given the system of equation in the question;

To find the solution to the system of equation, replace the occurrence of y in the second equation with y = 3x - 10  and solve for x.

y = -2x - 15

3x - 10 = -2x - 15

Add 10 to both sides

3x - 10 + 10 = -2x - 15 + 10

3x = -2x - 15 + 10

Add 2x to both sides

3x + 2x = -2x + 2x - 15 + 10

3x + 2x = - 15 + 10

Add like terms

5x = -5

x = -5/5

x = -1

Now, to solve for y, replace all occurrence of x with -1 in the first equation and solve for y.

y = 3x - 10

y = 3( -1 ) - 10

y = -3 - 10

y = -13

As a result, the answer to the following question, We may use the SAS criteria to argue that the two triangles are congruent if we know that KM is congruent to SU.

A triangle is a polygon because it contains four or more parts. It features a simple rectangular shape. A triangle ABC is a rectangle with the edges A, B, and C. When the sides are not collinear, Euclidean geometry produces a single plane and cube. If a triangle contains three components and three angles, it is a polygon. The corners are the points where the three edges of a triangle meet. The sides of a triangle sum up to 180 degrees.  

Option b: KM is congruent to SU is the additional information required by SAS to demonstrate Triangle KLM is congruent to Triangle UTS.

To demonstrate that two triangles are congruent using the SAS (Side-Angle-Side) congruence criterion, we must demonstrate:

Two comparable side pairs are congruent.

The angle included (the angle formed by these two sets of sides) is congruent.

In this situation, we are told that LM is congruent to ST, but we must still demonstrate that another pair of sides is congruent. We may use the SAS criteria to argue that the two triangles are congruent if we know that KM is congruent to SU.

Answer:

81 adult tickets were sold that day

Step-by-step explanation:

We will need a system of equations to solve for the number of adult tickets sold.

First equation: For reference, revenue refers to price * quantity.  

(price of child tickets * quantity of child tickets) + (price of adult tickets * quantity of adult tickets) = total revenue.

Allowing C to represent the number of child tickets and A to represent the number of adult tickets, our first equation is:

5.20C + 8.60A = 956.60

Second Equation:  

Thus, our second equation is:

C + A = 131

Method to Solve:  We can solve for A using substitution.  Let's isolate C in the second equation and plug it in for C in the first equation:

Isolating C in second equation:

(C + A = 131) - A

C = -A + 131

Substituting -A + 131 for C in first equation:

5.20 (-A + 131) + 8.60A = 956.60

-5.20A + 681.20 + 8.60A = 956.60

3.40A + 681.20 = 956.60

3.40A = 275.40

A = 81

Optional Checking Step:

We can check that we've correctly found the correct number of adult tickets sold by first using the second equation in our system to solve for C:

C + 81 = 131

C = 50

Second, we want to plug in 81 for A and 50 for C in both equations in our system and check that we get 956.60 and 131 respectively:

Checking solutions for first equation:

5.20(50) + 8.60(81) = 956.60

260.00 + 696.60 = 956.60

956.60 = 956.60

Checking solutions for second equation:

50 + 81 = 131

131 = 131

The CGF factor by grouping is 2(x + 6)(x - 1).

We are given that;

The equation 2x^2 + 10x - 12

Now,

Factorization is the method of breaking a number into smaller numbers that multiplied together will give that original form.

To find the GCF of 2x^2 + 10x - 12, we need to find the largest factor that can divide all the terms evenly. The GCF of 2, 10 and -12 is 2. So we can write:

2x^2 + 10x - 12 = 2(x^2 + 5x - 6)

To factor by grouping, we need to find two pairs of factors that add up to 5 and multiply to -6. One such pair is 6 and -1. So we can write:

2(x^2 + 5x - 6) = 2(x^2 + 6x - x - 6)

Then we can group the terms and factor out the common factors:

2(x^2 + 6x - x - 6) = 2[(x^2 + 6x) - (x + 6)]

= 2[x(x + 6) - (x + 6)]

= 2(x + 6)(x - 1)

Therefore, by factorization the answer will be 2(x + 6)(x - 1).

The least preferable and reliable method of selecting people to participate in a research study is convenience sampling.

Convenience sampling is a type of sampling in which you include people who are easy to reach. Convenience sampling is included in non-probability sampling because it doesn't include a random selection of the participants. Convenience sampling can be used when you need to conduct a study quickly or when you are on a shoestring budget as it is inexpensive compared to other methods of sampling.

It is the least preferable method because of the inability to generalize the result of the survey to the population as a whole. In addition to this, there is a possibility of under or over-representation of the population as a whole. The biggest problem with convenience sampling is dependence as the sample items are connected to each another in some way. This dependency interferes with statistical analysis.
