There were 100 adult tickets sold.
Substitution Method:When solving a system of equations with two unknowns, one of the techniques to find the unknown values is the substitution method. In this method, one equation is substituted to the other equation to achieve a final equation that contains only one of the unknowns. The value remaining unknown can be derived directly from the final equation. By substituting the first value to one of the original equations, the other unknown may be derived.
Let A be the number of adult tickets sold and S be the number of student tickets sold.
The total tickets sold is 275.
A + S = 275_________(Eq. 1)
Also, the total sales is $1025.
5A + 3S = 1,025_______(Eq. 2)
From the Equation 1
S = 275 - A [Subtract A from both sides]
Using this value of S, substitute S in the second equation.
5A + 3(275 - A) = 1,025
5A + 825 - 3A = 1,025
2A = 200 [Subtract both sides 825]
A = 100 [Divide both sides by 2]
Hence, There were 100 adult tickets sold.

largest possible value of x
Answer:
i) 9
ii) 11
Step-by-step explanation:
First off, what is a "mode"?
The mode in a set of data is simply the most common answer/outcome;
Next, we need to understand the data;
In this case, families were asked about the number of cats they have;
The children answered 0, 1, 2 or 3;
8 families have 0 cats,
6 have 1,
10 have 2,
x have 3
So, the mode will be the most common answer to how many cats a family has;
As we can see from the data, the most common response was 2, i.e. 10 families have 2 cats, compared to only 8 with 0 cats and 6 with 1 cat;
If we know the mode is 2, the value of x has to be less than 10 as it is not the most common response;
The largest possible value will be 9.
If the mode is 3, then that means the x has to be the greatest number of responses;
Since the greatest number of responses to the other options is 10, then the number of responses to having 3 cats has to be at least 11;
The smallest possible value of x, if the mode is 3, will be 11.
A puck moves 2.35 m/s in a -22.0° direction. A hockey stick pushes it for 0.215 s, changing its velocity to 6.42 m/s in a 50.0° direction. What is the displacement x
The displacement x of the moving puck is; 0.43 meters
How to find the displacement?The displacement is defined as the change in position of an object. It is also called a vector quantity and has a direction and magnitude
The parameters given here are;
The polar coordinate initial velocity vector; U = 2.35 m/s, -22°
Final velocity vector; V = 6.42 m/s, +50°
This suggests to us that Cartesian x axis is parallel to angle 0° and y axis is parallel to +90°.
Change of velocity component parallel to +90° = magnitude*sinθ,.
Thus, the change of that velocity
Δv = |V|sin(50) - |U|sin(-22)
Δv = 6.42sin(50) - 2.35sin(-22)
Δv = 4.9 - (-0.88)
Δv = +5.8 m/s
The equation for displacement is;
s = ut +1/2at^2
where acceleration time t = Δt = 0.215 s
initial velocity u = |U|sin(-22) = -0.88 m/s
acceleration parallel to u is a = Δv/Δt = +5.8/Δt
a = 5.8/t m/s^2
Thus;
s = -0.88t + ¹/₂* 5.8/t * t²
s = -0.88t +2.9t
s = 2.0t
s = 2.0 * 0.215
s = 0.43 m

The value of the missing internal angle in the irregular polygon is equal to 125°.
How to determine the missing measure of the remaining internal angle
The sum of internal angles (S), in degrees, in any convex polygon is determined by the following formula:
S = 180 · (n - 2)
Where n is the number of sides in the polygon.
According to the image seen beside, we find an irregular pentagon, that is, a polygon with five sides. First, determine the sum of internal angles:
S = 180 · (5 - 2)
S = 180 · 3
S = 540°

16y+20=3y+21
13y=1
y=1/13
Answer:
y = 1/13
Step-by-step explanation:
(4y + 5) : 3 = (y+7) :4
Product of extremes = (4y + 5) * 4
= 4y *4 + 5*4
= 16y + 20
Product of mean = 3*(y +7)
= 3*y + 3*7
= 3y + 21
Product of extremes = product of mean
16y + 20 = 3y + 21
Subtract 20 from both sides,
16y = 3y + 21 - 20
16y = 3y + 1
Subtract 3y from both sides,
16y - 3y = 1
13y = 1

Let's expand our thinking into the Third dimension. Can you think of a few ways to build a sphere? (No formula, just descriptions)
A geometric method is known as "stereographic projection" involves projecting a flat map of a sphere onto a three-dimensional surface with a point at its center.
This is one way to construct a sphere. The construction of geodesic domes, which gained popularity in the 1960s, is one example of an art and construction project that frequently makes use of this approach.
Using a solid material and carving it into the shape you want is another way to make a sphere. This can be accomplished using stone, clay, wood, and other materials. To produce a sphere with perfect symmetry, this method necessitates considerable skill and precision.
A third approach is to construct a sphere from numerous small, flat pieces. Paper or fabric can be used to accomplish this, with each piece being cut into a curved shape and glued together to form the sphere. Origami balls, for example, are a common decorative item made using this method.

ayudaa jajaja
The area and volume based on the information will be area 144 √3 square meters and 240√3 cubic meters
How to calculate the areaTo calculate the area of the hexagonal prism, you need to calculate the area of each face and add them up. To calculate the area of one face of the hexagon, you can use the following formula:
Area of a regular hexagon = (3 * √3) / 2 * side^2
Plug in the side length of 4m:
Area of a face = (3 * √3) / 2 * 4^2 = (3 * √3) / 2 * 16 = 24 * √3
So the area of one face is 24 * √3 square meters. There are a total of 6 faces, 3 of which are hexagons, so the total area of the hexagonal prism is:
Total area = 6 * (24 * √3) = 144 * √3 square meters
To calculate the volume of the hexagonal prism, multiply the area of one face by the height:
Volume = (24 * √3) * 10 = 240 * √3 cubic meters
So the volume of the hexagonal prism is 240 * √3 cubic meters

∠A and ∠B are vertical angles. If m∠A = (7x+4) and m∠B = (8x - 20) then find the measure of ∠B
Since ∠A and ∠B are vertical angles, they have equal measures, so m∠A = m∠B. We can set the two expressions equal to each other:
7x + 4 = 8x - 20
Solving for x:
-x = -24
x = 24
So, m∠A = 7x + 4 = 7 * 24 + 4 = 188, and m∠B = 8x - 20 = 8 * 24 - 20 = 188.
Therefore, the measure of ∠B is 188 degrees.

solve the following systems of linear equations by graphing
y=2/3x+4 and y=/x-1
Answer:
The solution to the system is (1.8, 7.6)
Step-by-step explanation:
To solve the system of linear equations by graphing, we need to plot the two lines on the same coordinate plane and find the point where they intersect, which will be the solution of the system.
Plot the lines:
y = 2/3x + 4 can be written as y = (2/3)x + 4, where the slope is 2/3 and the y-intercept is 4.
y = -x + 1 can be written as y = -x + 1, where the slope is -1 and the y-intercept is 1.
Find the intersection point:
To find the intersection point, we can substitute the x-value from one equation into the other equation. Let's use y = 2/3x + 4.
Substitute x from y = 2/3x + 4 into y = -x + 1:
-x + 1 = 2/3x + 4
Multiplying both sides by -3, we get:
3x - 3 = -2x - 12
Adding 2x to both sides, we get:
5x - 3 = -12
Adding 12 to both sides, we get:
5x = 9
Dividing both sides by 5, we get:
x = 1.8
Now that we have x, we can substitute it back into either equation to find the corresponding y-value. Let's use y = 2/3x + 4:
y = 2/3x + 4
y = 2/3 * 1.8 + 4
y = 3.6 + 4
y = 7.6
So the solution to the system is (1.8, 7.6), which is the point where the two lines intersect.

As part of their opening day celebration, Benny’s Bakery made 150 cupcakes. The cupcakes all looked identical on the outside, but 6 of them had caramel inside. Customers who bought a cupcake with a caramel inside won a free cake. The cupcakes were randomly arranged and customers were allowed to choose their own cupcakes. Zoe was the first customer in line and bought three cupcakes. What is the probability that exactly one of Zoe’s cupcakes had caramel inside?
The probability that exactly one of Zoe's cupcakes had caramel inside after the cupcakes were randomly arranged and customers were allowed to choose their own cupcakes is 1/3266.
The probability that exactly one of Zoe's cupcakes had caramel inside can be calculated as follows:
P(exactly one cupcake with caramel) = (number of ways to choose one cupcake with caramel) / (total number of combinations of three cupcakes)
