Icket sales tickets for a high school play are $3.00 each for students and $4.00 each for all others. find the total money collected from ticket sales if 315 student tickets are sold out of a total of 518 tickets
315 x 3 = 945
518 - 315 = 203
203 x 4 = 812
945 + 812 =1757
So the answer is $1,757 total
The total money collected from ticket sales for the high school play, with 315 student tickets sold at $3.00 each and 203 other tickets sold at $4.00 each, is $1,757.00.
To find the total money collected from ticket sales, we need to calculate the revenue from both student tickets and tickets sold to others. We know that 315 student tickets were sold at a price of $3.00 each, and the remaining tickets sold to others were at a price of $4.00 each. Since a total of 518 tickets were sold, the tickets sold to others amount to 518 - 315 = 203 tickets.
Revenue from student tickets = 315 tickets imes $3.00 per ticket = $945.00
Revenue from other tickets = 203 tickets imes $4.00 per ticket = $812.00
Total revenue from ticket sales = Revenue from student tickets + Revenue from other tickets = $945.00 + $812.00 = $1,757.00
Therefore, the total money collected from ticket sales is $1,757.00.
What is the equation of a line perpendicular to the line y=(4/9)x-2 that passes through the point (4,3)?
a. y= -(4/9)x-2
b. y= (9/4)x+6
c. y= -(9/4)x+12
d. y= -(9/4)x-12
(pls explain solution!!)
To find the equation of a line perpendicular to y=(4/9)x-2 that passes through the point (4,3), we need to determine the slope of the original line and then find the negative reciprocal of that slope. The equation of the perpendicular line is y = -(9/4)x + 12.
To find the equation of a line perpendicular to y=(4/9)x-2 that passes through the point (4,3), we need to determine the slope of the original line and then find the negative reciprocal of that slope. The original line has a slope of 4/9, so the perpendicular line will have a slope of -9/4. Using the point-slope form of a line, we can plug in the slope and the given point to find the equation of the perpendicular line:
y - y1 = m(x - x1)
where (x1, y1) is the given point and m is the slope. Plugging in the values, we get:
y - 3 = -(9/4)(x - 4)
Simplifying the equation, we get:
y = -(9/4)x + 12
Therefore, the equation of the line perpendicular to y=(4/9)x-2 that passes through the point (4,3) is y = -(9/4)x + 12.

Which graph represents the system of inequalities?
y+32x>−3
y−5≤−6x
Rewrite the systems of inequalities in slope-intercept form, and then graph the lines using the respective inequalities. The shaded area that overlaps will represent the solution to these systems of inequalities.
Explanation:In order to determine a graph that represents the system of inequalities, y+32x > -3 and y-5 ≤ -6x, you will need to write the systems of inequalities in mathematical terms, known as slope-intercept form (y = mx + b), where m is the slope and b is the y-intercept.
Firstly, let's rewrite the first inequality as y > -32x - 3. This inequality suggests that y is greater than -32x - 3, therefore the area above the line will be shaded.
Next, the second inequality is rewritten as y ≤ 6x + 5. This suggests y is less than or equal to 6x + 5, thus the area below the line will be shaded.
Remember, when creating the graph, a solid line should be used for ≤ symbol and a dashed line for the > symbol. The overlapping region of the two inequalities on the graph is the solution to the system of inequalities.

Write a reciprocal function with asymptotes x=4 and y=-9.
Final answer:
To write a reciprocal function with asymptotes x=4 and y=-9, the function is f(x) = -9/(x-4).
Explanation:
To write a reciprocal function with asymptotes x=4 and y=-9, we need to find the equations of the vertical and horizontal asymptotes.
For the vertical asymptote, the equation is x=4. This means that the function approaches infinity as x approaches 4 from the left or right.
For the horizontal asymptote, the equation is y=-9. This means that the function approaches -9 as x approaches infinity or negative infinity.
Therefore, the reciprocal function with these asymptotes is:
f(x) = -9/(x-4)
Final answer:
To create a reciprocal function with asymptotes x=4 and y=-9, the function can be expressed as y = 1/(x-4) - 9. This form ensures a vertical asymptote at x=4 and a horizontal asymptote at y=-9.
Explanation:
To write a reciprocal function with asymptotes x=4 and y=-9, you need to include factors that will create these asymptotes in the function's equation. A reciprocal function generally has the form y = a/(x-h) + k, where (h, k) represents the horizontal and vertical shifts to create the asymptotes x=h and y=k. In this case, we have:
y = 1/(x-4) - 9
This function has a vertical asymptote at x=4 because as x approaches 4, the denominator approaches 0 causing the function to approach infinity. The horizontal asymptote at y=-9 occurs because as x goes to infinity, the value of 1/(x-4) approaches 0, and the entire function approaches -9.

A group of n students is assigned seats for each of two classes in the same classroom. how many ways can these seats be assigned if no student is assigned the same seat for both classes?
The number of ways the seats can be assigned is equal to n factorial (n!).
Explanation:The number of ways the seats can be assigned is given by the permutation formula. Since there are n students and 2 classes, each student can be assigned a seat in the first class in n ways. After that, there are (n-1) seats left and (n-1) students remaining to be assigned seats in the second class. Therefore, the total number of ways to assign seats is n * (n-1) * (n-2) * ... * 1, which is equal to n factorial (n!).

A 3-ounce serving of tuna provides 21 g of protein use equivalent ratios to find how many grams of protein are in 9 ounces of tuna! Explain
Answer: 63 grams of protein in 9 ounces of tuna
Step-by-step explanation: To find how many grams of protein are in 9 ounces of tuna, we can use equivalent ratios.
We know that a 3-ounce serving of tuna provides 21 grams of protein.
Let's set up a ratio:
3 ounces of tuna: 21 grams of protein
To find out how many grams of protein are in 9 ounces of tuna, we can set up a proportion:
3 ounces of tuna / 21 grams of protein = 9 ounces of tuna / x grams of protein
To solve for x, we can cross-multiply:
(3 ounces of tuna)(x grams of protein) = (9 ounces of tuna)(21 grams of protein)
3x = 189
Dividing both sides of the equation by 3:
x = 63
Therefore, there are 63 grams of protein in 9 ounces of tuna.
Hope this helps have a great day :)!!!!
True or false: given a sample mean of 2.1 and a sample standard deviation of 0.7 from a sample of 10 data points, a 90% confidence interval will have a width of 2.36.
A 90% confidence interval will have a width of 2.36 which is false.
What is a confidence interval?Let μ be the mean, σ be the standard deviation, n be the ample size, and z be the z-score. Then we have
Confidence interval = μ ± z (σ / √n)
A sample mean of 2.1 and a sample standard deviation of 0.7 from a sample of 10 data points.
We know that the z-score for 90% of the confidence interval is 1.645. Then we have
Confidence interval = μ ± z (σ / √n)
Confidence interval = 2.1 ± 1.645 (0.7 / √10)
Confidence interval = 2.1 ± 0.364
For positive sign, then the width will be
⇒ 2.1 + 0.364
⇒ 2.46
A 90% confidence interval will have a width of 2.36 which is false.

Two consecutive even integers have a sum of 42 . find the integers.
If two consecutive even integers have a sum of 42. The integers are 20 and 22.
What is an integer?it is defined as a whole number it can be a negative whole number or a positive whole number for example 2, 4, 1, -8, 0, etc.
It is given that, two consecutive even integers have a sum of 42.
The difference between two even numbers is 2.
Suppose two consecutive even integers are x , (x+2)
x + (x+2) = 42
We have to apply the arithmetic operation in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that are +, -, ×, and ÷.
2x +2 = 42

What is the equation of a line that passes through the point (4, 2) and is perpendicular to the line whose equation is y=x/3−1 ? Enter your answer in the box.
Lines can be parallel, perpendicular or have no relationship at all.
The equation of the line is: [tex]\mathbf{y = -3x + 14}[/tex]
First, we calculate the slope of: [tex]\mathbf{y = \frac x3 - 1}[/tex]
A linear equation is represented as:
[tex]\mathbf{y = mx + c}[/tex]
Where:
m represents the slope
So, by comparison:
[tex]\mathbf{m = \frac 13}[/tex]
From the question, we understand that the required line is perpendicular to [tex]\mathbf{y = \frac x3 - 1}[/tex]
This means that, the slope (m2) of the required line is:
[tex]\mathbf{m_2 = -\frac 1m}[/tex]
So, we have:
[tex]\mathbf{m_2 = -\frac 1{1/3}}[/tex]
[tex]\mathbf{m_2 = -3}[/tex]
The equation of the line is:
[tex]\mathbf{y = m_2(x - x_1) + y_1)}[/tex]
Where:
[tex]\mathbf{(x_1,y_1) = (4,2)}[/tex]
So, we have:
[tex]\mathbf{y = -3(x - 4) + 2}[/tex]
Open bracket
[tex]\mathbf{y = -3x + 12 + 2}[/tex]
[tex]\mathbf{y = -3x + 14}[/tex]
Hence, the equation of the line is: [tex]\mathbf{y = -3x + 14}[/tex]
