Ticket sales fell $960 below the goal.

What is system of equations?

A system of linear equations can be solved graphically, by substitution, by elimination, and by the use of matrices.

Since we know that the goal is to raise $3,300 each night and that the price of an adult ticket is $7.50 and the price of a student ticket is $4.50, we can write:

7.5d + 4.5s = 3300

We also know that the auditorium holds 600 people, so the total number of tickets sold must be:

d + s = 600

total number of tickets sold was 480. We can use this information to set up another system of equations:

s = 3d (since there were three times as many student tickets sold as adult tickets)

d + s = 480 (since the total number of tickets sold was 480)

Now we can solve the first system of equations to find the values of d and s that satisfy the constraints:

7.5d + 4.5s = 3300

d + s = 600

Multiplying the second equation by 4.5 and subtracting it from the first equation, we get:

3d = 1650

So, d = 550. Substituting this value back into the equation d + s = 600, we get:

550 + s = 600

s = 50

Therefore, 550 adult tickets and 50 student tickets must have been sold to raise exactly $3,300.

To answer the second part of the question, we can use the second system of equations to find the values of d and s for that performance:

s = 3d

d + s = 480

Substituting the first equation into the second equation, we get:

d + 3d = 480

So, 4d = 480 and d = 120. Substituting this value back into the first equation, we get:

s = 3d = 360

Therefore, 120 adult tickets and 360 student tickets were sold at that performance.

To calculate how much below the goal of $3,300 ticket sales fell, we can plug in the values for d and s from this performance into the equation:

7.5d + 4.5s = revenue

7.5(120) + 4.5(360) = $2,340

So, ticket sales fell $960 ($3,300 - $2,340) below the goal.

The area of the following circle is A ≈ 153.86 square units.

A circle is a two-dimensional geometric shape that consists of all the points in a plane that are equidistant from a fixed point called the center. The distance from the center to any point on the circle is called the radius, and the distance across the circle passing through the center is called the diameter.

The circumference of a circle is the distance around the edge of the circle, and it is calculated using the formula C = 2πr, where r is the radius and π (pi) is a mathematical constant approximately equal to 3.14159. The area of a circle is the region enclosed by the circle, and it is calculated using the formula A = πr².

The diameter of the circle is 14, so the radius is half of that, which is 7.

The area of the circle is given by the formula A = πr², where r is the radius. Substituting in the values we get:

A = π(7)²

A = 49π

Therefore, the area of the circle is 49π square units. If you want to use an approximation, you can use 3.14 as an estimate for π and get:

A ≈ 153.86 square units.

The location of the corner of the rabbit pen that reflects (2.5, 2.5) across the y-axis is (-2.5, 2.5).

The coordinate plane, also called the Cartesian plane, is a two-dimensional grid used to locate points in space. It consists of two perpendicular number lines, one horizontal and one vertical, that intersect at their zero points, called the origin.

Points on the coordinate plane are identified by their coordinates, which are written as ordered pairs of numbers (x, y), where x is the horizontal coordinate and y is the vertical coordinate.

To solve this problem, we need to reflect the point (2.5, 2.5) across the y-axis. When we reflect a point across the y-axis, we keep the y-coordinate the same but change the sign of the x-coordinate.

So, the reflected point will have the same y-coordinate of 2.5, but the x-coordinate will be -2.5. Therefore, the location of the corner of the rabbit pen that reflects (2.5, 2.5) across the y-axis is (-2.5, 2.5).

The coordinates of A' and B' after a dilation with a scale factor of 2 with a center point of dilation at the origin is: OA (-8, 2) and B (-2, 6)

To find the coordinates of A' and B' after a dilation with a scale factor of 2 with a center point of dilation at the origin, we can use the following formula:

A' = k * (A - O) + O

B' = k * (B - O) + O

where k is the scale factor, O is the center point of dilation, and A and B are the original points.

In this case, k = 2 and O = (0, 0). So we have:

A' = 2 * (-4, 1 - (0, 0)) + (0, 0) = (-8, 2)

B' = 2 * (-1, 3 - (0, 0)) + (0, 0) = (-2, 6)

The given LP problem is to maximize f(x,y)=3x+19y subject to the constraint set of the feasible set. The extreme points of the feasible set are (0,0), (1,0), (0,1), and (1,1).

To prove that (x,y)=(1,1) is an optimal solution, we need to show that f(x,y) is maximized at this point. We can do this by plugging in the extreme points into the objective function and comparing the values.

At (0,0), f(x,y) = 3(0) + 19(0) = 0

At (1,0), f(x,y) = 3(1) + 19(0) = 3

At (0,1), f(x,y) = 3(0) + 19(1) = 19

At (1,1), f(x,y) = 3(1) + 19(1) = 22

From these calculations, we can see that f(x,y) is maximized at (1,1), with a value of 22. Therefore, (x,y)=(1,1) is an optimal solution for this LP problem.

In conclusion, by plugging in the extreme points of the feasible set into the objective function and comparing the values, we have proved that (x,y)=(1,1) is an optimal solution for the given LP problem.

The sum of the circumferences of the two circles is equal to [tex]$2\pi \sqrt 2.$[/tex]

Circumference is the distance around a two-dimensional shape, such as a circle or ellipse. It can be calculated by multiplying the circumference of the shape by its diameter. The formula for calculating the circumference of a circle is 2πr, where π is the constant 3.14 and r is the radius of the circle. The circumference of an ellipse is more complicated and requires knowledge of the length of its major and minor axes.

The two circles are externally tangent to each other, which means that the distance between them is equal to the sum of their radii. Since the circles are tangent to the sides of the square, the length of one side of the square is equal to the sum of their radii. Since the perimeter of the square is given to be [tex]$2+\sqrt 2,[/tex] we can calculate the length of each side of the square to be [tex]$\sqrt 2.$[/tex] Hence, the sum of the radii of the two circles is equal to [tex]$\sqrt 2.$[/tex]

Answer:

Step-by-step eEIKxplanation:

Answer:

There are a total of 15 customers, so the probability of selecting any one customer at random is 1/15.

If the first customer selected is a Pike resident, there are 6 Pike residents remaining out of a total of 14 customers remaining. So the probability of the second customer being a Pike resident, given that the first customer was a Pike resident, is 6/14.

Therefore, the probability of both customers selected being Pike residents is:

(6/15) * (6/14) = 0.1714 or approximately 0.17 (rounded to two decimal places).

So the probability that both customers selected are Pike residents is approximately 0.17.

We are only interested in the critical numbers on the interval [1,3], so we can disregard x = 0. Therefore, the critical numbers of the function f(x) on the interval [1,3] are x = 3.

The critical numbers of a function are the points where the derivative of the function is either zero or undefined. To find the critical numbers of the given function f(x) = x^2/(3-x), we need to first find its derivative:

f'(x) = (2x(3-x) - (-1)x^2)/ (3-x)^2 = (6x - x^2 - x^2)/ (3-x)^2 = (6x - 2x^2)/ (3-x)^2

Now, we need to find the values of x for which f'(x) = 0 or f'(x) is undefined. f'(x) is undefined when the denominator (3-x)^2 is equal to 0, which occurs when x = 3. f'(x) is equal to 0 when the numerator 6x - 2x^2 is equal to 0:

6x - 2x^2 = 0
2x(3 - x) = 0
x = 0 or x = 3

However, we are only interested in the critical numbers on the interval [1,3], so we can disregard x = 0. Therefore, the critical numbers of the function f(x) on the interval [1,3] are x = 3.

Note that the pair of numbers that solves the system of equations:

y=11x+40; and

y= -7x+9

are,  x = -31/18  ; and y = 379/18.

To solve the system of equations, we need to find the values of x and y that satisfy both equations simultaneously. One way to do this is to set the expressions for y equal to each other, since both expressions represent the same value of y.

So we have:

11x + 40 = -7x + 9

Simplifying and solving for x, we get:

18x = -31

x = -31/18

Now that we have found the value of x, we can substitute it into either equation to find the corresponding value of y. Let's use the first equation:

y = 11(-31/18) + 40

y = -341/18 + 720/18

The value of angle e is 55⁰.

The value of angle f is 55⁰.

The value of angle e is calculated by applying the following principles of angles on a straight line.

The vertical angle between e⁰ and 100⁰ = 25⁰ ( vertically opposite angles are equal)

The value of angle e is calculated as;

e⁰ + 25⁰ + 100⁰ = 180⁰ ( sum of angles on a straight line )

e⁰ = 180⁰ - 125⁰

e⁰ = 55⁰

The missing base angle of the triangle on the same line as e is calculated as;
