a theater has 144 seats. the theater sells tickets for $6 per adult and $4 per child

Let x be the number of adult tickets

and y be the number of child tickets

Total number of tickets sold is 144

x + y = 144  -----------> equation 1

the theater sells tickets for $6 per adult and $4 per child and earned $660

6x + 4y = 660  ----------> equation 2

Solve for x  and y

x + y = 144

y = 144 - x

Now plug it in second equation

6x + 4y = 660

6x + 4(144 - x) = 660

6x + 576 -4x = 660 (combine like terms)

2x + 576 = 660 (subtract 576 from both sides)

2x = 84 (divide by 2)

x= 42

Number of adult tickets = 42

y = 144 - x

y = 144- 42= 102

Number of child tickets = 102

The theater sold 42 adult tickets and 102 child tickets on Friday night, calculated by setting up and solving a system of equations based on the total seats and revenue.

To solve the problem, we need to set up a system of equations based on the information provided. The total number of seats is 144, and the total revenue from selling out on Friday night is $660. Let A represent the number of adult tickets sold and C represent the number of child tickets sold. Therefore we have the following equations:

Now we can solve this system of equations. Multiplying the first equation by 4, we get 4A + 4C = 576. Subtracting this from the second equation cancels out the C, leaving us with 2A = 84, or A = 42. Plugging this into the first equation gives us C = 144 - 42, or C = 102.

Therefore, the theater sold 42 adult tickets and 102 child tickets on Friday night.

Answer:

[tex]y\geq \frac{1}{2}x[/tex]

Step-by-step explanation:

To find the inequality represent by the graph, we first must find the linear equation that represents that line.

So, in first place, we find the slope of the line, using two point (0,0) and (2,1):

[tex]m=\frac{y_{2}-y_{1} }{x_{2}-x_{1} }=\frac{1-0}{2-0}=\frac{1}{2}[/tex]

Now, using one point, the slope and the slope-point formula, we find the linear expression

[tex]y-y_{1}=m(x-x_{1})\\y-0=\frac{1}{2}(x-0)\\ y=\frac{1}{2}x[/tex]

Then, with the linear expression, we just need to take a test point form the shaded area and evaluate the expression, the point is gonna be (0,1):

[tex]y=\frac{1}{2}x\\1=\frac{1}{2}(0)\\ 1=0[/tex]

We know that 1 is more than zero, this means that the right inequality sign is [tex]\geq[/tex], due to the relation of the numbers, and because line is solid.

Therefore, the inequality is

[tex]y\geq \frac{1}{2}x[/tex]

Answer:

voltage drop across 40Ω inductor is 41.2V

Step-by-step explanation:

We are given that a series RL circuit contains two resistors 27Ω, 47Ω and two inductors which have reactances 50Ω,40Ω.

Hence total resistance in the circuit =27+47=74Ω

Total reactance=50+40=90Ω

Since all of these elements are in series, same current goes through all the elements.

And that current I=[tex]\frac{E_{T}} {Z}[/tex]

Given Applied voltage,[tex]E_{T}=120V[/tex]

Hence [tex]I=\frac{120}{\sqrt{74^{2}+90^{2}}} =\frac{120}{\sqrt{13576}} =1.03A[/tex]

Therefore voltage drop on the inductor that has 40Ω of reactance=40X1.03

                                                                           =41.196≈41.2V

Final answer:

The voltage drop on the inductor in a series RL circuit with a 40 Ω reactance is calculated using the total impedance and Ohm's Law to find the circuit current, which is then multiplied by the inductor's reactance. The calculated voltage drop is 41.2 V.

Explanation:

The student is dealing with an RL circuit and needs to calculate the voltage drop on an inductor with a given reactance in that circuit. In an RL circuit, the total impedance (Z) is found by combining the resistive (R) and inductive reactance (XL) components together, where R is the sum of individual resistances and XL is the sum of individual reactances. Since the components are in series, the total resistance would be R = 27 Ω + 47 Ω = 74 Ω and the total reactance would be

XL = 50 Ω + 40 Ω = 90 Ω.

The total impedance (Z) can be calculated using the Pythagorean theorem for the right triangle formed by R and XL:

=  [tex]\sqrt{(74^2 + 90^2)[/tex]

= √(5476 + 8100)

= √(13576) ≈ 116.52 Ω.

With the total impedance known, we can find the current in the circuit (I) using Ohm's Law:

I = V/Z

= 120 V / 116.52 Ω

≈ 1.03 A.

The voltage drop across an individual inductor can be found by ∗ V = I * XL, where XL is the inductive reactance of the inductor in question. Therefore, the voltage drop for the inductor with a 40 Ω reactance is:

V = 1.03 A * 40 Ω

= 41.2 V.

This is the voltage drop on the inductor with a 40 Ω reactance.

Answer: The width can be measured in not a characteristic of a plane

Step-by-step explanation: Think about it it doesn't make sense becuase it doesn't have measurable width

Anywhere there is a point, is part of the domain.  So we see a point at x = -2. x = 0, x = 1, x= 2, x = 3, and x = 4.

So the domain would be

{-2, 0, 1, 2, 3, 4}

Answer choice 1.

It's 13.5 because you put them in order and then you have 13 and 14 you add them together and then divide by 2

So you first have to order them least to greatest, which would be : 8 , 9 , 13, 14 , 15, 16. Since the number of numbers is even, average the 2 middle numbers. This is 13 + 14 divided by 2 or 13.5.

The first quartile is the middle of the first half.

Which would be the number 12 I think

Answer:

1) point-slope form

2) slope intercept form

Explanation:

1) y−b=m(x−a)

m = slope

(a, b) A point that the line passes through

2) y=mx+b

m = slope

b = y-intercept

The required difference between slope intercept form and point-slope form line is when we have slope and y-intercept we use slope-intercept equation and when we have coordinates of a point on the line we use the point-slope form of the line.

The slope of the line is the tangent angle made by the line with horizontal. i.e. m =tanx where x in degrees.

The slope-intercept form of the equation of a line is,

y =  mx +c   - - - - - - (1)

The point-slope form of the line is given by,

(y - y1) = m(x - x1)    - - - - - - (2)
where m is the slope of equation and m = (y2 - y1) / (x2 - x 1).

Thus, we use a slope-intercept form of the equation when we have given the slope of the line and y-intercept of the line. when we have a coordinate of one point and slope or more than two coordinates of points on the line so we use the point-slope form of the equation.

Compensation is the process of reformulating an addition, subtraction, multiplication, or division problem to one that can be computed more easily mentally.

We will use compensation to find the difference of 30,000 and 6985.

Since, we have to evaluate 30,000 - 6,985

Let us add '15' to 6985,

6,985 + 15 = 7,000

Let us add '15' to 30,000

30,000 + 15 = 30,015

Now, we have to subtract 30,015  and 7,000

= 30,015 - 7,000

= 23,015

Therefore, the difference of 6,985 from 30,000 is 23,015.

The strategy of compensation involves adjusting numbers to make calculations easier. In the case of finding the difference between 30000 and 6985, you would adjust 6985 to 7000, subtract it from 30000 to get 23000, then add back the 15 you added to 6985 at the beginning. The result is 23015.

In mathematics, compensation is a strategy where you adjust one of the numbers to make the equation easier to solve. Pivotally, you make the same adjustment to the other number so as not to change the overall result.

Let's use this strategy to find the difference between 30000 and 6985

So, through the use of compensation the difference between 30000 and 6985 is 23015.

A: For this equation you would use distributive property leading you to multiply 3x and 2 by 4 giving you a new expression. 12x + 8 - 2. After this you would just simplify the equation by subtracting 2 from 8 giving you 6. This leading to a new equation, 12x + 6.

B: In order to factor the expression you would need to do the reverse of distributive property, finding the GCF, or greatest common factor between the 16 and the 20b. When you do this you result in getting 4 as your GCF. Afterwards you need to divided the numbers by the GCF. Leading you to get 4(5b-4). This is how you would factor the equation.

Step-by-step explanation:

Given: the water temperature at the beach started at 82 degrees and it is rising 0.6 degrees each hour

To Find: If the water temperature is now 85 degrees write and solve an equation to find h, the number of hours that have passed

Solution:

Current water temperature at beach [tex]=82^{\circ}[/tex]

temperature rising rate degrees per hour [tex]=0.6^{\circ}[/tex]

let [tex]\text{h}[/tex] be the hours passed.

water temperature at the beach after hour [tex]\text{h}[/tex] be

                                                                       [tex]= 82+0.6\text{h}[/tex]

Therefore,

equation for water temperature after [tex]\text{h}[/tex] [tex]\text{hour}[/tex] is

                    [tex]= 82+0.6\text{h}[/tex]

When water temperature is [tex]85^{\circ}[/tex]

                    [tex]85=82+0.6\text{h}[/tex]

                    [tex]0.6\text{h}=85-82[/tex]

                    [tex]0.6\text{h}=3[/tex]

                    [tex]\text{h}=\frac{3}{0.6}[/tex]

                    [tex]\text{h}=5[/tex] [tex]\text{hours}[/tex]

therefore it will take  [tex]5[/tex] [tex]\text{hours}[/tex] to reach temperature [tex]85^{\circ}[/tex]

Initial temperature = 82°

Rate of temperature rise = 0.6° per hour

Final temperature = 85°

The equation which describes the relationship :

Final temperature = Initial temperature + (rate × number of hours)

Number of hours = h

Mathematically, the relationship can be written as :

85 = 82 + 0.6h

Solving for h :

Subtract 82 from both sides :

85 - 82 = 0.6h

3 = 0.6h

Divide both sides by 0.6

3/0.6 = h

h = 5

Hence, the temperature will be 85° after 5 hours

Answer:

The correct option is:  A.  X= -4

Step-by-step explanation:

The equation of the given line is:  [tex]x=7[/tex]

As the given line is a vertical line parallel to y-axis, that means the slope of the line is 'undefined' or [tex]\frac{k}{0}[/tex], where [tex]k[/tex] is any real number.

Now, the slope of the line which is parallel to the given line will be also [tex]\frac{k}{0}[/tex], as the slopes of parallel lines are always equal.

The parallel line is passing through the point (-4, 1). So, using point-slope form.......

[tex]y-y_{1}= m(x-x_{1})\\ \\ y-1=\frac{k}{0}(x-(-4))\\ \\k(x+4)=0\\ \\ x+4=0\\ \\ x=-4[/tex]

Thus, the equation of the parallel line will be:  [tex]x=-4[/tex]
