Answer:
let the number of adult tickets = x
Then the number of student tickets = 3x
Total tickets x+3x = 416
4x = 416
x = 416/4
x = 104
Therefore the number of adult tickets sold is 104

Are (2, 5) and (5, 2) the same location? Why or why not?
Answer:
They are not in the same location
Step-by-step explanation:
Well because we have x axis and y axis, x always has to go first. In (2, 5) 2 is first and has to start from the x axis and 5 is the y axis. And the (5,2) is the opposite and the places would be in totally different places on the coordinate plane.
Answer: No
Step-by-step explanation: The order of coordinates for a given point is very important. For example, (2, 5) and (5, 2) represent two very different points on a coordinate system, as shown in the picture below.
A given point, such as (2, 5), is often reffered to as
an ordered pair because the order of coordinates is very important.

Answer:
Tim is correct. 5/8 > 1/2
Step-by-step explanation:
By taking 5/8 of the lasagna, Tim will be taking more than half (4/8) of it. No remaining share can be larger. Any remaining share will be 3/8 or less, so will be smaller than a 5/8 share.
Tim's 5/8 share is the largest.
Use Hooke's Law to determine the work done by the variable force in the spring problem. A force of 450 newtons stretches a spring 30 centimeters. How much work is done in stretching the spring from 30 centimeters to 60 centimeters?
Answer:
The work done is 202.50Nm
Step-by-step explanation:
Given
[tex]F =450N[/tex]
[tex]x_1 = 30cm[/tex]
[tex]x_2 = 60cm[/tex]
Required
The work done
First, we calculate the spring constant (k)
[tex]F = kx_1[/tex]
[tex]450N = k *30cm[/tex]
[tex]k = \frac{450N}{30cm}[/tex]
[tex]k =15N/cm[/tex]
So:
[tex]F = kx_1[/tex]
[tex]F(x) = 15x[/tex]
The work done using Hooke's law is:
[tex]W =\int\limits^a_b {F(x)} \, dx[/tex]
This gives:
[tex]W =\int\limits^{60}_{30} {15x} \, dx[/tex]
Rewrite as:
[tex]W =15\int\limits^{60}_{30} {x} \, dx[/tex]
Integrate
[tex]W =15 \frac{x^2}{2}|\limits^{60}_{30}[/tex]
This gives:
[tex]W =15 *\frac{60^2 - 30^2}{2}[/tex]
[tex]W =15 *\frac{2700}{2}[/tex]
[tex]W =15 *1350[/tex]
[tex]W =20250N-cm[/tex]
Convert to Nm
[tex]W =\frac{20250Nm}{100}[/tex]
[tex]W =202.50Nm[/tex]

A 16 ft ladder leans against the side of a house. The bottom of the ladder is 9 ft away from the side of the house. Find x, the angle of elevation of the ladder. Round your answer to the nearest tenth of a degree. (plz help listing BRAINLIST)
Answer:
55.8
Step-by-step explanation:
cos(x)=9/16
x=55.8
The angle of elevation of the ladder is approximately 60.5 degrees.
To find the angle of elevation (x) of the ladder, we can use trigonometry. The ladder, the side of the house, and the ground form a right triangle. The length of the ladder is the hypotenuse of the right triangle, and the distance from the bottom of the ladder to the house is one of the legs.
Using the tangent function:
tan(x) = opposite/adjacent
tan(x) = 16 ft / 9 ft
Now, solve for x:
x = arctan(16/9)
Using a calculator, we find
x ≈ 60.5 degrees
So, the angle of elevation of the ladder is approximately 60.5 degrees.

Answer:
D
Step-by-step explanation:
The inequality symbol is < (not ≤), which means the end point of the graph will be an open circle.
After dividing by the coefficient of x, you have an inequality of the form ...
x +( ) < ( )
which means the solution will be left of the (open circle) end point of the graph. Only one graph has that form.

If you actually work through the numbers, you get ...
x +8 < 9 . . . . . . divide both sides by 2.9
x < 1 . . . . . . . . . subtract 8 from both sides
Which graph represents the function f(x) = –x2 + 5?
Answer:
Step-by-step explanation:
The graph of f(x) = –x^2 + 5 is that of an upside-down parabola with vertex (0, 5) and x-intercepts (-√5, 0) and (+√5, 0). Plot the vertex (0, 5) and then draw a smooth curve through it and through the x-intercepts.
The function f(x) = -x2+5 is thus represented by the quadratic functions in the first graph.
what is quadratic functions ?A quadratic function has the formula f(x) = ax2 + bx + c, with a, b, and c being integers and a not equal to zero. Parabolas can have openings that are upward or downward, different "widths" or "steepnesses," but they all share the same fundamental "U" shape.
here calculation
The function provided is f(x) = -x2+5
.... (1) (1)
We must locate the function's graph.
The quadratic function's vertex form is f(x)= a(x-h)2 + k.... (2)
When we compare (1) and (2), we obtain
h=0 , k=5
It denotes that the function's vertex is (0,5).

9514 1404 393
Answer:
A
Step-by-step explanation:
It is usually sufficient to look at one section of the graph to answer a question like this. Often the best choice is the section that has a solid dot at the end of the curve. Here, that is the right section.
The left end of the right section is at x=-2, so that part of the function is defined for x ≥ -2. The line to the right has a positive slope, so the coefficient of x will be positive.
Only one answer choice has a positive x-coefficient for x ≥ -2.

b. n(A'UC)

Answer:
[tex]n(A\ u\ B) = 10[/tex]
[tex]n(A'\ u\ C) = 10[/tex]
[tex]n(A\ n\ B)' = 6[/tex]
Step-by-step explanation:
Given
[tex]n(U) = 12[/tex]
[tex]n(A\ n\ B) =n(A\ n\ C) = n(B\ n\ C) =6[/tex]
[tex]n(A\ n\ B\ n\ C)=4[/tex]
[tex]n(A\ u\ B\ u\ C)=10[/tex]
Required
Solve a, b and c
There are several ways to solve this; the best is by using Venn diagram (see attachment for diagram)
Solving (a):
[tex]n(A\ u\ B)[/tex]
This is calculated as:
[tex]n(A\ u\ B) = n(A) + n(B) - n(A\ n\ B)[/tex]
From the attachment
[tex]n(A) = 0+2+4+2 = 8[/tex]
[tex]n(B) = 0+2+4+2 = 8[/tex]
[tex]n(A\ n\ B) = 4 +2 = 6[/tex]
So:
[tex]n(A\ u\ B) = 8 + 8 - 6[/tex]
[tex]n(A\ u\ B) = 10[/tex]
Solving (b):
[tex]n(A'\ u\ C)[/tex]
This is calculated as:
[tex]n(A'\ u\ C) = n(A') + n(C) -n(A'\ n\ C)[/tex]
From the attachment
[tex]n(A) = n(U) - n(A) = 12 - 8 = 4[/tex]
[tex]n(C) = 0+2+4+2 = 8[/tex]
[tex]n(A'\ n\ C) = 2[/tex]
So:
[tex]n(A'\ u\ C) = 4 + 8 - 2[/tex]
[tex]n(A'\ u\ C) = 10[/tex]
Solving (c):
[tex]n(A\ n\ B)'[/tex]
This is calculated as:
[tex]n(A\ n\ B)' = n(U) - n(A\ n\ B)[/tex]
[tex]n(A\ n\ B)' = 12- 6[/tex]
[tex]n(A\ n\ B)' = 6[/tex]
3y=150, what is the value of y-2
Answer:
y = 48
Step-by-step explanation:
Start with the given 3y = 150.
Solve this for y by dividing both sides by 3: y = 50
Then y - 2 = 50 - 2, or
y = 48
The value of y-2 is 48,
What is an equation?Two expressions connected by an equal sign makes an equation.
Given is an equation, 3y = 150
Solving for y,
3y = 150
y = 150 / 3
y = 50
therefore, y-2 = 50-2
= 48
Hence, the value of y-2 is 48,
