The total amount that the band earns when the concert  sells out is $18566.50

Given,

Number of seats in The Playhouse Concert Hall = 523

The cost for one ticket charged by The Pink Ladies rock band who holds a concert = $35.50

We have to find the total amount that the band earns when the concert  sells out;

Total amount = Number of seats x Cost for one ticket

Total amount = 523 x 35.50

Total amount that the band earn = $18566.5

Answer:

The expression "2(x + 6) + x" would make the equation unsolvable (i.e., no solution),

Step-by-step explanation:

This initially appears to be an odd question, since one might imagine that there would always be a solution for x, no matter what is put into the "box."  But lets take a look and see what the possible solutions look like when compared to the original equation.  First, rearrange the reference equation so that we can better compared it to the answer options:

3 (x + 1) + 9 = box

3x + 3 + 9 = box

3x + 12 = box

3(x + 4) = box

Now look through the answer options and evaluate how, or if, they may be able to prevent us from finding an actual value or x::

-------------------------

     Option[Box]    Reformatted     Complete Equation   Unsolvable?

                                                            3x + 12 = 3x +12    

                                                               0 = 0                        YES*

                                                              3x + 12 = 11x - 12

                                                               -8x = -24

                                                                   x = 3                        NO

                                                               2(x+4) = 0

                                                                 2x = -8

                                                                    x = -4                      NO    

*  The YES answer means that this expression would make the answer unsolvable.  Note that the expressions on both sides of the equation are equal.  So there is no one answer.  Any choice of a value for x will always be a valid solution.  A singkle value is not possible with this equation.

Step-by-step explanation:

The dimensions x and x+50 are 150 ft by 200 ft. When two polygonal or polyhedral vertices are not on the same edge, a diagonal is a line segment connecting them.

When two polygonal or polyhedral vertices are not on the same edge, a diagonal is a line segment connecting them. Any sloping line is known as a diagonal informally.

If you draw a diagonal, you have 2 right triangles, each with leg lengths of x and x + 50.

The diagonal is the hypotenuse, h = 250

Using Pythagorean theorem:

X² + (x+50)² = 250²

x² + x²+ 100x + 2500 = 62500

2x²+ 100x - 60000 = 0

All are even, so factor out a 2:

x² + 50x - 30000 = 0

From quadratic equation:  x = [-50±√(50²-4(1)(-30000))]/(2(1))

x = (-50 ± 350)/2

We can disregard the negative so

x = (-50 + 350)/2 = 300/2 = 150 ft

The dimensions x and x+50 are 150 ft by 200 ft

The complete question is: A rectangular parking lot is 50ft longer than it is wide. Determine the dimensions of the parking lot if the diagonal distance from corner to corner of the lot is 250ft.

There are four components in division namely divisor, dividend, quotient and remainder. The significance and meaning of each is evident from their name. The dividend is the number that is being divided. And the number which is used to divide the dividend is divisor. The result of dividing the dividend by divisor is termed as quotient. Remainder is the left over amount.

Step-by-step explanation:

1.657−2.397(5.968x−0.27)=4.193x−3

Use the distributive property to multiply −2.397 by 5.968x−0.27.

1.657−14.305296x+0.64719=4.193x−3

Add 1.657 and 0.64719 to get 2.30419.

Combine −14.305296x and −4.193x to get −18.498296x.

2.30419−18.498296x=−3

Subtract 2.30419 from both sides.

Answer: ∠1 = 90°

Step-by-step explanation:

      There are a few steps we will take to solve this problem. In each step, I will write an equation to help us solve, then use inverse operations to solve.

      First, we will use the exterior angles theorem to find the measurement of ∠3 (this will help us solve for ∠2, then for ∠1).

89° = 51° + ∠3

∠3 = 38°

      Next, we will find the measurement of ∠2 since we know ∠2 plus ∠3 is 90 degrees, as shown by the perpendicular lines and the box.

90° = ∠3 + ∠2

90° = 38° + ∠2

∠2 = 52°

      Lastly, we will solve for ∠1. We know that there are 180 degrees in a triangle.

180° = 38° + ∠1 + ∠2

180° = 38° + ∠1 + 52°

180° = 90° + ∠1

∠1 = 90°

Answer:

90

Step-by-step explanation:

I started by finding angle 5

180 - 89 = 91  Supplemental angles

Then I found angle 3

The sum of the interior angles of a triangle is 180

180-89-91 = 38

Angle2 and 3 are complementary angles

90- 38 =52

the sum of the interior angles of a triangle is 180

Angle 1

180 - 52 - 38 = 90

Answer:

[tex]y = \dfrac{3x}{2} -3[/tex]

Step-by-step explanation:

Before we identify the equation of the line in slope intercept form, we must identify the slope intercept form equation. The slope intercept form equation is y = (m)x + (b) ⇒ m = slope of line; b = y-intercept of line.

To identify the equation of the line shown in slope intercept form, according to the slope intercept form equation, we need to identify the slope of the line and the y-intercept of the line. The slope of a line is the rate of a line, which advances up/down/side-to-side at a constant rate. The y-intercept of a line is the intersection of the line at the y-axis.

There is a specific formula for identifying the slope:

[tex]\boxed{\text{Slope} = \dfrac{\text{y coordinate of 2nd point - y coordinate of 1st point}}{\text{x coordinate of 2nd point - x coordinate of 1st point}}}[/tex]

Some facts about slope: The slope of a line will also depend on the graph. If the graph ascends upward to somewhere in Quadrant 1 or 2, the slope of the line will be positive. If the graph descends downward to somewhere in Quadrant 3 or 4, the slope will be negative. If the line horizontal and it passes perfectly through the x-axis, the slope of the line is 0. If the slope of the line is vertical, then the slope will be undefined.

Location of plotted points: First point: (0, -3); Second point: (2, 0)

Let us now identify the x and y coordinates of the plotted points:

[tex]\boxed{\text{y-coordinate of 2nd point = 0; y-coordinate of 1st point = -3}} \\ \boxed{\text{x-coordinate of 2nd point = 2; x-coordinate of 1st point = 0 }}[/tex]

Plug the coordinates into the slope formula to determine the slope:

[tex]\implies {\text{Slope} = \dfrac{\text{0 - (-3)}}{\text{2 - 0}}} = \dfrac{0 + 3}{2} = \dfrac{3}{2}[/tex]

Plug the slope of the line into the slope intercept form equation:

[tex]\implies y = (m)x + (b)[/tex]

[tex]\implies y = \huge\text{(}\dfrac{3}{2} \huge\text{)}x + (b)[/tex]

[tex]\implies y = \dfrac{3(x)}{2} + b[/tex]

Let us plug any point (that is on the line) for x and y. This will help us find the y-intercept (b). I will plug in the first point because it is my preference.

[tex]\implies y = \dfrac{3(x)}{2} + b[/tex]

[tex]\implies -3 = \dfrac{3(0)}{2} + b \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ [\text{First point: (0, -3)} \implies x = 0; y = -3]}[/tex]

[tex]\implies -3 = 0 + b[/tex]

[tex]\implies -3 = b[/tex]

Finally, let us substitute the slope of the line and the y-intercept of the line into the slope-intercept form equation. Then, we can simplify both sides of the equation and isolate the y-variable completely on the other side.

[tex]\implies y = (m)x + (b)[/tex]

[tex]\implies y = \huge\text{(}\dfrac{3}{2} \huge\text{)}x + (-3)[/tex]

[tex]\implies y = \dfrac{3x}{2} -3[/tex]

Therefore, the equation of the line in slope intercept form is y = 3x/2 - 3.
