Answer:

x = -5/2

Step-by-step explanation:

-15/2 = 3x

multiply both sides by 2:

2(-15/2) = 2(3x)

-15 = 6x

divide both sides by 6:

-15/6 = 6x/6

x = -15/6

this can be reduced to:

Step-by-step explanation:

The polar coordinate system uses two parameters r and θ where r is the magnitude of the radius of the circle in polar form(also known as the radial coordinate) and θ  the angle which the which the radius makes relative to the x=axis

The following equations are used to convert from cartesian coordinate to polar coordinates

The sum of the measures of an exterior angle of a polygon is 360°.

If the given angle divides 360 evenly, then it can be a measure of an exterior angle of a polygon. If otherwise, then it cannot be.

Out of the given angles, only 50 does not divide 360 evenly. Therefore, a regular polygon cannot have an exterior angle measuring 50°. (Option B)

Applying the trapezoid midsegment theorem, the diameter of the bottom layer of the cake = KS = 26 inches.

The diameter of any circular shape is the length of the line segment that divides the shape into two equal halves and runs through its center.

The trapezoid midsegment theorem states that the length of the midsegment of a trapezoid that is parallel to its bases is equal to half of the sum of the bases.

Using the trapezoid midsegment theorem we have:

MQ = 1/2(NP + LR)

Substitute

MQ = 1/2(8 + 20)

MQ = 1/2(28)

MQ = 14 inches

Also, we would also have:

LR = 1/2(MQ + KS) [trapezoid midsegment theorem]

Substitute

20 = 1/2(14 + KS)

40 = 14 + KS

40 - 14 = KS

26 = KS

KS = 26

The diameter = KS = 26 inches.

sin(40 + 2°) cosec(30 + 5°) = 1 we proved that by the values.

Given,

sin(40 + 2°) cosec(30 + 5°) = 1

To prove the trigonometry function equal to 1.

Now, According to the question:

We know that

Sin 42° = 0.66913061

Cosec 35° = 1.7434468

sin(40 + 2°) cosec(30 + 5°) = 1

sin 42° × cosec 35° = 1

Plug the values of sin and cosec in above function:

0.66913061 × 1.7434468

= 1.16659

But we take the before decimal value i.e., 1

Hence,  sin(40 + 2°) cosec(30 + 5°) = 1 we proved that by the values.

The perimeter of the triangle ABC is 36 cm. Then the correct option is A.

A triangle is a three-sided polygon with three angles. The angles of the triangle add up to 180 degrees. If two triangles are similar, then the ratio of the corresponding sides will remain one.

Triangle ABC is congruent to triangle XYZ. In AABC, AB = 12 cm and AC = 14 cm. In AXYZ, YZ = 10 cm and XZ = 14 cm.

AB = XY = 12 cm

The mean age of customers is 27.35 years.

It is well known that age has a normal distribution with a 5-year standard deviation. Additionally, 30% of the time, customers are under the age of 30.

Mathematically,

P (age ≤ 30) = 0.70

Let μ be the mean age of the customer.

P [z ≤ (30 - μ) / σ] = 0.70

The equivalent of "age" in a conventional normal distribution is the z-score or z. It is evident from the usual normal distribution table that when z=0.53, 0.70 probability is reached.

Thus,

z = (30 - μ) / σ

⇒ 0.53 = (30 - μ) / 5

⇒ μ = 27.35

As a result, the average consumer is 27.35 years old.

The probability at each z-score in a standard normal table is represented by the associated z-score. We will look for the number 0.70 in the table, then the row value of 0.5 and the associated column value of 0.03 will be examined. They add up to 0.53 when combined.

Answer:

1320 seats.

Step-by-step explanation:

The given scenario can be modeled as an arithmetic series.

[tex]\boxed{\begin{minipage}{7.3 cm}\underline{Sum of the first $n$ terms of an arithmetic series}\\\\$S_n=\dfrac{1}{2}n[2a+(n-1)d]$\\\\where:\\\phantom{ww}$\bullet$ $a$ is the first term. \\ \phantom{ww}$\bullet$ $d$ is the common difference.\\ \phantom{ww}$\bullet$ $n$ is the position of the term.\\\end{minipage}}[/tex]

The first term is the number of seats in the front row.

Given that the number of seats in a row increases by 2 with each successive row, the common difference is 2.

The nth term is 30 since there are 30 rows in the theater.

Therefore:

Substitute the values into the arithmetic series formula and solve:

[tex]\implies S_{30}=\dfrac{1}{2}(30)[2(15)+(30-1)2][/tex]

[tex]\implies S_{30}=15[30+(29)2][/tex]

[tex]\implies S_{30}=15[30+58][/tex]

Answer:29

Step-by-step explanation:

This postulate tells us that when we put two angles side by side with a ray touching the ray of the other angle, we are creating a new angle which is the addition of the two, and whose measure is the addition of the measures of the two angles we are contacting via a common ray.

Answer:

The missing angle in Triangle A is 66 degrees

The missing angle in Triangle B is 34 degrees

Because Triangle A has measures of 34 degrees, 80 degrees, and 66 degrees

and

Triangle B has measures of 80 degrees, 66 degrees, and 34 degrees, we can conclude that THEY ARE SIMILAR TRIANGLES

Explanation:

The sum of angles in a triangle is 180 degrees.

Given that triangle A has m<1 = 34 degrees, m<2 = 80 degrees. Let the missing angle be x, then

x + 34 + 80 = 180

x + 114 = 180

Subtract 114 from both sides

x = 180 - 114

= 66 degrees

Triangle B has m<1 = 80 degrees, m<2 = 66 degreess. Let the missing angle be y, then

y + 80 + 66 = 180

y + 146 = `180

Subtract 146 from both sides

y = 180 - 146

= 34 degrees

Triangles A and B are similar, since they have similar measure of angles.
