The number of $56 dollar tickets to center section was 200 and the number of tickets costing $38 to the left and right sections were 200.

Let us consider the number of tickets to the center section be x and right and left sections be y.

Here the total number of tickets sold are 540.

So,  x+ y = 540  ---------> i

The cost of tickets cost $56 will be 56x

The cost of tickets cost $38 will be 38y.

The total cost was given as $24120

So, 56x+ 38y = 24120 -----------> ii

Multiplying equation i with 56,

56x + 56y = 30240  ------------> iii

Subtracting equation ii from equation iii

   56x+ 56y = 30240

-   56x + 38y = 24120

So 18y = 6120

      y = 6120/18 = 340

Since x+ y = 540

          x+ 340 = 540

          x = 540- 340 = 200

So the number of $56 ticket sold is 200 and the number of $38 ticket sold is 340.

The slope of the perpendicular to the line of slope -10/3 is 3/10.

What is meant by the perpendicular of a line?

A straight line that forms a right angle (90 degrees) with another line is referred to as being perpendicular. Two lines are perpendicular to one another if they cross one other at a straight angle. The term "perpendicular to all points in the plane" or "perpendicular to each line it intersects" is used to describe a line that is perpendicular to the plane. Two lines will always be parallel to one another if they are perpendicular to the same line. If and only if the slope product of the two lines equals minus one, two lines are perpendicular to one another.

Given a straight line with a slope of -10/3.

We are asked to find the slope of the perpendicular to this line.

The equation of the line that's vertical to the given line and passes through the point(,6) is y = (-2/3) x28/3.

To find the equation of a line vertical to a given line, we need to use the fact that the pitches of two vertical lines are negative reciprocals of each other.

Let's start by chancing the pitch of the given line. The equation of a line in pitch- intercept form is y = mx b, where m is the pitch and b is the y- intercept. We can rewrite the given line 3x- 2y = 5 in pitch- intercept form by working for y

3x- 2y = 5

- 2y = -3 x 5

y = (3/2) x-5/2

So the pitch of the given line is3/2.

The pitch of a line vertical to this line is the negative complementary of3/2, which is-2/ 3.

Now we can use the point- pitch form of the equation of a line to find the equation of the line that passes through the point(,6) and has pitch-2/ 3. The point- pitch form is

y- y1 = m( x- x1)

where( x1, y1) is the point the line passes through and m is the pitch.

Substituting in the values we know, we get

y- 6 = (-2/3)( x- 5)

Expanding the right side, we get

y- 6 = (-2/3) x10/3

Adding 6 to both sides, we get

y = (-2/3) x28/3

So the equation of the line that's vertical to the given line and passes through the point(,6) is y = (-2/3) x28/3.

Using the theorem of angle around a point, the value of GHJ is 237 degrees

When we talk about the "angle around a point," we are usually referring to the total angle formed by two or more lines or line segments that intersect at a common point, known as the vertex.

Specifically, the "angle around a point" is equal to 360 degrees or 2π radians. This is because, when two or more lines intersect at a point, they form multiple angles, and the sum of these angles is always equal to 360 degrees or 2π radians.

Since we know that FPJ and JPI are congruent, this implies that they're equal to one another. We can find the value by setting them as x

x + x + 51 + 66 + 99 = 360

Reason: The sum of angles around a point is equal to 360 degrees

2x + 216 = 360

2x = 360 - 216

2x = 144

x = 72

Answer:

Step-by-step explanation:

To find the amount Rob will have in 5 years with compound interest, we can use the formula:

A = P (1 + r/n)^(nt)

where:

A = the future value of the investment

P = the principal amount invested

r = the annual interest rate (as a decimal)

n = the number of times the interest is compounded per year

t = the number of years

In this case, we have:

P = $7,869 (the principal amount)

r = 13% or 0.13 (the annual interest rate)

n = 1 (the interest is compounded annually)

t = 5 (the number of years)

Substituting these values into the formula, we get:

A = $7,869 (1 + 0.13/1)^(1*5)

A = $7,869 (1.13)^5

A = $14,964.92

Therefore, to the nearest cent, Rob will have $14,964.92 in 5 years.

Step-by-step explanation:

Let A be a symmetric matrix, which means that A is equal to its own transpose, i.e., A = Aᵀ. We want to prove that if A is invertible, then its inverse A⁻¹ is also symmetric.

To show that A⁻¹ is symmetric, we need to show that (A⁻¹)ᵀ = A⁻¹.

We know that A is invertible, so A⁻¹ exists. Taking the transpose of both sides of the equation A = Aᵀ, we get:

(Aᵀ)ᵀ = A

which simplifies to:

A = Aᵀ

Multiplying both sides of this equation by A⁻¹, we get:

A⁻¹ A = A⁻¹ Aᵀ

Using the property of transpose (i.e., (AB)ᵀ = Bᵀ Aᵀ), we can rewrite the right-hand side of the equation as:

A⁻¹ Aᵀ = (A A⁻¹)ᵀ = Iᵀ = I

where I is the identity matrix.

Substituting this back into the original equation, we get:

A⁻¹ A = I

Taking the transpose of both sides of this equation, we get:

(A⁻¹ A)ᵀ = Iᵀ

which simplifies to:

Aᵀ (A⁻¹)ᵀ = I

Using the property of transpose again, we can rewrite the left-hand side of the equation as:

(A⁻¹)ᵀ Aᵀ = (A A⁻¹)ᵀ = Iᵀ = I

Substituting this back into the equation, we get:

(A⁻¹)ᵀ Aᵀ = I

which can be rearranged as:

(A⁻¹)ᵀ = (Aᵀ)⁻¹

Since we know that A = Aᵀ, we can substitute this into the equation to get:

(A⁻¹)ᵀ = A⁻¹

which shows that A⁻¹ is symmetric. Therefore, if a symmetric matrix is invertible, then its inverse is symmetric also.

The Celsius (symbol: °C) is an SI (International System of Units) derived unit of temperature.

The Fahrenheit (symbol: °F) is a unit of temperature that was widely used prior to metrication.

To convert a temperature from Fahrenheit (°F) to Celsius (°C),

We can use the following formula:

°C = (°F - 32) x 5/9

Where °C is the temperature in Celsius and °F is the temperature in Fahrenheit.

Substituting 70 for °F, we get:

°C = (70 - 32) x 5/9
