a theater charges $8 for an adult ticket and $6 for a childerns ticket on a certin day a total of 225 tickets were sold for a total cost of $1,850 how many more childerns tickets were sold than sold than adult tickets
The number of adult tickets sold more than the children's tickets are 65.
It is given in the question that the charge of an adult ticket and a children's ticket is $8 and $6 respectively.
It is also given that, on a certain day the number of tickets sold are 255 at a total cost of $1,850.
We have to find the number by which children's ticket were sold more than adult tickets.
Let the number of children tickets sold on that particular day be x.
Let the number of adult tickets sold on that particular day be y.
Hence, according to the question,
x + y = 255 ...(1)
Also,
6*x + 8*y = 1850
Dividing 2 from both sides, we get
3x + 4y = 925 ...(2)
Multiplying (1) by 3, we get
3x + 3y = 765 ...(3)
(2) - (3)
(3x - 3x) + (4y - 3y) = 925 - 765
0 + y = 160
y = 160
Hence, the number of adult tickets sold are 160.
We know that,
x + y = 255
Hence,
x + 160 = 255
x = 255 - 160
x = 95
Hence, the number of children's tickets sold are 95.
The number of adult tickets sold more than the children's ticket are =
160 - 95 = 65 tickets.

The system of linear functions for the graph below is given as follows:
y = -0.5x + 1.y = -4x - 6.How to define a linear function?The slope-intercept representation of a linear function is given by the equation presented as follows:
y = mx + b
The coefficients of the function and their meaning are described as follows:
m is the slope of the function, representing the change in the output variable y when the input variable x is increased by one.b is the y-intercept of the function, which is the initial value of the function, i.e., the numeric value of the function when the input variable x assumes a value of 0. On a graph, it is the value of y when the graph of the function crosses the y-axis.For the first line, we have that:
The intercept is of b = 1, as when x = 0, y = 1.The slope is of m = -0.5, as when x increases by 2, y decays by 1.Hence the equation is:
y = -0.5x + 1.
For the second line, we have that:
The intercept is of b = -6, as when x = 0, y = -6.The slope is of m = -4, as when x increases by 2, y decays by 8.Hence the equation is:
y = -4x - 6.

Is y = e - 5x-8 a solution to the differential equation shown below? y-5x = 3+y Select the correct answer below: Yes No
No, y = e^(-5x-8) is not a solution to the differential equation y - 5x = 3 + y.
To determine if y = e^(-5x-8) is a solution to the differential equation y - 5x = 3 + y, we need to substitute y = e^(-5x-8) into the differential equation and check if it satisfies the equation.
Substituting y = e^(-5x-8) into the equation:
e^(-5x-8) - 5x = 3 + e^(-5x-8)
Now, let's simplify the equation:
e^(-5x-8) - e^(-5x-8) - 5x = 3
The equation simplifies to:
-5x = 3
This equation does not hold true for any value of x. Therefore, y = e^(-5x-8) is not a solution to the differential equation y - 5x = 3 + y.

Find the volume of a right circular cone that has a height of 18.8 inches and a base with a diameter of 14.3 inches. Round answer to the nearest tenth of a cubic inch.
Answer:
The volume of the right circular cone is \(1005.9\ \text{inch}^2\).
Step-by-step explanation:
It is given that,
Height of a right circular cone is 18.8 inches and its diameter is 14.3 inches. We need to find the volume of the cone. The volume of cone is
\(V=\dfrac{1}{3}\pi r^2 h\)
So,
\(V=\dfrac{1}{3}\times 3.14\times (\dfrac{14.3}{2})^2\times 18.8\\\\V=1005.9\ \text{inch}^2\)
So, the volume of the right circular cone is \(1005.9\ \text{inch}^2\).

Step-by-step explanation:
A stock loses half its value each week. If the stock started at $125, what is it worth after 4 weeks?
Answer: 7.81
The formula is
y = 125* (1/2)^4
y = 125 / 16
y = 7.81
So at the end of the 4th week, the stock is worth only 7.81 dollars.
If that is not the motive and the first week doesn't count then the formula changes to...
y = 125 * (1/2)^(n-1)
y = 125 * (1/2)^3
y = 15.625 could be the other answer if you looked at it in that perspective
However, I would go with 7.81 as the answer.

How much storage is needed to represent a simple graph with n vertices and m edges using
a) adjacency lists?
b) an adjacency matrix?
c) an incidence matrix?
The amount of storage required to represent a simple graph with n vertices and m edges can vary depending on the chosen representation. Here's the storage requirement for each representation:
a) Adjacency lists:
In an adjacency list representation, we typically use an array of size n to store the vertices, and for each vertex, we maintain a linked list or an array to store its adjacent vertices. The space complexity of this representation is O(n + m), where n is the number of vertices and m is the number of edges.
Each vertex requires constant space, and each edge is represented by a link or entry in the adjacency list.
b) Adjacency matrix:
In an adjacency matrix representation, we use a 2D matrix of size n x n to represent the graph. Each entry (i, j) in the matrix represents whether there is an edge between vertices i and j. The space complexity of this representation is O(n^2), as we need to store n^2 entries for the complete matrix. However, if the graph is sparse (few edges compared to vertices), the space complexity can be reduced to O(n + m) by only storing the entries corresponding to the existing edges.
c) Incidence matrix:
In an incidence matrix representation, we use a 2D matrix of size n x m, where n is the number of vertices and m is the number of edges. Each entry (i, j) in the matrix represents whether vertex i is incident to edge j. The space complexity of this representation is O(n * m), as we need to store n * m entries for the matrix.
Similar to the adjacency matrix, if the graph is sparse, the space complexity can be reduced to O(n + m) by storing only the entries corresponding to the existing edges.
In summary:
a) Adjacency lists: O(n + m)
b) Adjacency matrix: O(n^2) or O(n + m) for sparse graphs
c) Incidence matrix: O(n * m) or O(n + m) for sparse graphs

Answer:
y = 2.5x
Step-by-step explanation:
use y = mx + c
m = gradient (rise/run)
c = y intercept at x = 0
m = 10 / 4 = 2.5
c = 0
y = 2.5x
becuase c = 0 you dont add it into the equation
Answer:
y=mx + c.
the y intercept is represented by c, this is where our line meets the y axis. here our y intercept is 0, because the line meets the y axis at the point 0 on the y axis. therefore, we discard this from the equation as it has no meaning/relevance. the gradient is equal to the rise over run. so, the line had risen by ten, and ran across by 5. 10÷5=2. so, the equation of the line is just y=2x hope this helps.!!!

Kiara drew a scale drawing of an apartment. The scale of the drawing was 11 millimeters : 4 meters. The actual length of the dining room is 8 meters. How long is the dining room in the drawing?
Answer:
22 millimeters
Step-by-step explanation:
Given that:
Scale of drawing = 11 millimeters : 4 meters
This means 4 meters of actual is represented as 11 millimeters on the drawing
If actual length of dining room = 8 meters ;
Lenght of dinning room in drawing will be x :
11 millimeters = 4 meters
X millimeters = 8 meters
Cross multiply :

4x = 88
x = 88/4
x = 22
Hence, the length of the drawing will be 22 millimeters

The interquartile range of the given data set is 8 inches.
Here, we have,
To find the interquartile range (IQR) of a dataset, we first need to arrange the data in ascending order.
The heights which are heights in inches of the 10 high school varsity basketball players are:
71, 71, 72, 74, 74, 75, 78, 79, 79, 83
Next, we calculate the first quartile (Q1) and third quartile (Q3) positions.
Q1 is the median of the lower half of the dataset, and Q3 is the median of the upper half.
If the dataset that has an odd number of values, the median is the middle value.
If the dataset that has an even number of values, the median is the average of the two middle values.
In this case, we have 10 values, so we calculate Q1 and Q3 as follows:
Q1 = (72 + 74) / 2 = 73
Q3 = (79 + 83) / 2 = 81
Finally, we calculate the interquartile range (IQR) by subtracting Q1 from Q3:
IQR = Q3 - Q1 = 81 - 73 = 8
Therefore, the interquartile range of the given data set is 8 inches.
