Four friends shared the cost of a pizza dinner. They ordered 1 large pizza for $17.50, 4 sodas for $1.25 each, and 4 salads. Salads normally cost $1.75 but were on sale: "Buy one, get one free." If the friends split the total cost of dinner equally, what was each person's share?
Answer:
$6.50
Step-by-step explanation:
So writing out everything
1 Pizza = $17.50
1 soda = $1.25
1 salad = $1.75
Exception; Salad is buy 1 get 1 free, so only 2 salads were paid for
Now we multiple
1 Pizza * 17.50 = 17.50
4 soda * 1.25 = 5
2 salad * 1.75 = 3.50
Now we add
17.50 + 5 = 22.50 + 3.50 = $26.00
Now lastly, we divide by 4 since there are 4 friends
26/4 = 6.5
Giving us a answer of $6.50

The translation of point A to point B is done by translation vector (- 3, - 6).
How to determine the translation vector
In this problem we find the a point that is part of a rectangle and that must be translated by means of a rigid transformation formula, that is, a translation formula that does not alter the features of the rectangle. We need to determine the translation vector by means of the following formula:
T(x, y) = B(x, y) - A(x, y)
Where:
A(x, y) - Initial pointB(x, y) - Final pointT(x, y) - Translation vectorIf we know that A(x, y) = (6, 9) and B(x, y) = (3, 3), then the translation vector is:

The distribution of time it takes for people to solve a certain Sudoku puzzle is strongly skewed to the right. This means that most people take a shorter amount of time to solve the puzzle, but some take a longer amount of time. The mean (average) of this distribution is 30 minutes and the standard deviation is 15 minutes.
To find the distribution of z-scores, we need to convert the times into z-scores, which is done by subtracting the mean (30) from each time and then dividing by the standard deviation (15). This gives us a new distribution of z-scores, which is centered at 0 (since the mean of the times was subtracted from each time) and has a standard deviation of 1.

problem solving you go on a hayride to take photographs of landmarks. the map shows your path and two landmarks. each unit in the coordinate plane corresponds to 10 yards. approximate your minimum distance from the giant pumpkin. if necessary, round your answer to the nearest tenth.
The minimum distance from the giant pumpkin is 8.9 yards.
We will use the minimum distance formula between a line and a point to obtain the distance in this case.
A linear function is given according to the standard notation by:
Ax+By+C=0
A point with 'x' and 'y' coordinates are given by:
P(x*,y*)
The formula to find the shortest distance between a point and a line is denoted by the formula:
d=|Ax*+By*+C|/√(A²+B²)
In this issue, the path's line includes:
When x = 0, and y = 0, the intercept is 0.
0.5 slope means that when x rises by 4, y rises by 2.
Thus, y=1/2x
-1/2x+y=0
or, -x+2y=0
The coefficients of the line are:
A=-1 and B=2
Coordinates of the giant pumpkin is (x*,y*)=(-4,-3)
Therefore, the minimum distance is:
d=|(-1)(-4)+2(-3)|/√5
or,d=2/√5
or, d=0.89 units
We know, 1 unit=10 yards
or, 0.89 units=8.9 yards
Thus, the minimum distance between a point and a line is 8.9 yards.

The proportion of electric toothbrush prices are between 104.60 dollars and 108.20 dollars are 0.0099.
What is Normal Distribution?A normal distribution in statistics is defined as the type of continuous probability distribution where the datas are arranged in a symmetrical bell shaped graph.
Given that,
Mean, μ = 87
Standard deviation, σ = 8
We have to calculate P (104.60 < x < 108.20).
For that find z score.
z = (x - μ) / σ
At x = 104.60, z = (104.60 - 87) / 8 = 2.2
At x = 108.20, z = (108.20 - 87) / 8 = 2.65
From the z table,
P(z < 2.65) = 0.9960 and P(z < 2.2) = 0.9861
P (104.60 < x < 108.20) = 0.9960 - 0.9861 = 0.0099

Find the lateral surface area of the solid above.
Answer here
The answer for lateral surface area of the Triangular prism is 180 cm²
What is Lateral Surface Area?Any solid object's lateral area can be calculated using the lateral area formula. Any figure's lateral area only includes the non-base faces. Calculating the lateral surface area of various forms, such as the cuboid, cube, cylinder, cone, and sphere, is made easier using lateral area formulas.
The lateral area for a triangular prism
A triangular prism's lateral area is equal to the sum of its side faces' areas (which are 3 rectangles). Specifically, it is the total surface area less the surface areas of the two bases. Additionally called the lateral surface area (LSA). Due to the two dimensions involved in its calculation, we measure it in square units.
The total of the three regions is the triangular prism's lateral area. Consequently, the triangular prism's lateral area formula is
Triangular prism lateral surface area (LSA) = ah + bh + ch (or) (a + b + c) h.
We are aware that the perimeter of the base is (a + b + c) (triangle). Hence,
Triangular prism's lateral surface area (LSA) is equal to the product of the base's perimeter and the prism's height.
base perimeter × height
Explanation
The Given Image of the solid is Matching to a prism.so we are calculating the lateral surface area of the prism
The dimensions of each base are:
a = 5cm
b = 4 cm
c = 3 cm
The height of the triangular prism = 15cm.
Thus, the lateral area of triangular prism = (a + b + c ) h

In each figure for what values of x and y is the figure a parallelogram
The values of x and y that makes the figure a parallelogram are x = 17 and y = 26
How determine what values of x and y makes the figure a parallelogram?
A parallelogram is a four-sided geometric shape that has opposite sides that are parallel to each other.
The opposite sides of a parallelogram have the same length, and the opposite angles are also equal. The opposite sides of a parallelogram are also known as the bases, and the other two sides are known as the legs.
Since the opposite sides of a parallelogram are equal in length, we can say:
3x + 6 = 4 - x
3x + x = 4 - 6
4x = -2
x = -2/4
x = -1/2 = -0.5
y + 2 = 2y - 3
2 + 3 = 2y - y
5 = y
y = 5
Likewise, the opposite angles of a parallelogram are equal, so we can say:
(4x - 12)° = (3x + 5)°
4x - 12 = 3x + 5
4x - 3x = 5 + 12
x = 17
(3y + 46)° = (5y - 6)°
3y + 46 = 5y - 6
46 + 6 = 5y - 3y
52 = 2y
2y = 52
y = 52/2
y = 26
Thus, x = 17 and y = 26 makes the figure a parallelogram

What is angle q in the triangle that is shown below? Side x =
66.1 cm, side y = 22.8 cm, and angle f = 23.3º.
Please round your answer to one decimal place.
In the triangle, we will use the Law of Cosines to find the value of angle q. angle q in the triangle is approximately 61.2° (rounded to one decimal place).
What is Law of Cosines?The Law of Cosines is a mathematical formula used in trigonometry to find the length of a side or an angle in a triangle.
The formula can be used to find the length of a side or an angle in a triangle, given the length of the other sides and angles.
The Law of Cosines is particularly useful when only two sides and the angle between them are known, or when only two angles and the side between them are known.
To use the Law of Cosines, you need to identify the sides and angles that you know and plug them into the formula. Then, you can use algebra to solve for the unknown side or angle.
The Law of Cosines is related to the Pythagorean Theorem, which states that in a right triangle, the sum of the squares of the lengths of the two shorter sides is equal to the square of the length of the longest side.
The Law of Cosines can also be used in three-dimensional geometry to find the distance between two points in space.
The Law of Cosines is a useful tool in many fields, including engineering, physics, and computer graphics, and is widely used in solving geometric problems.
In this triangle, we have x = 66.1 cm, y = 22.8 cm, and angle f = 23.3º. We want to find angle q, which is opposite side x.
We can use the Law of Cosines to find the value of cos(q), and then use the inverse cosine function to find the value of q in degrees.
cos(q) = (x² + y² - x²)/(2xy)
cos(q) = (66.1² + 22.8² - 22.8²)/(2 * 66.1 * 22.8)
cos(q) = 67.8664/150.6448
cos(q) = 0.449
q = cos⁻¹(0.449)
q = 61.2°
Therefore, angle q in the triangle is approximately 61.2° (rounded to one decimal place).

According to the figure the two triangles congruency state cannot be determined
D. cannot be determinedWhat does triangular congruency mean?Triangles are considered congruent when their sides and angles match those specified by the triangle congruency rules.
The triangle congruency rules.
Side - Side - Side = SSS.
Angle - Side - Side = SAS
Side - Angle - Angle = ASA
Angle, Angle, and Side = AAS
Hypotenuse plus one leg = HL
To demonstrate that the triangles are congruent, the is need for three parameters to be known except for right triangle
In the problem, only two parameters can be deduced the side and the angle equal by vertical angle theorem

Answer:
1. Funnel cakes- 12
2. Oreos- 21
Step-by-step explanation:
1. x= 42/3.50
x=12
2. y= 42/2
y= 21
the owner of an automobile repair shop studied the waiting times for customers who arrive at the shop for an oil change. the following data with waiting times in minutes were collected over a one-month period. 9 11 3 12 11 4 3 3 4 24 13 22 5 18 6 9 12 23 15 2 (a) develop a frequency distribution using classes of 0-4, 5-9, 10-14, 15-19, and 20-24.
Classes Frequency
0-4 7
5-9 5
10-14 2
15-19 4
20-24 1
The frequency of each class is determined by counting the number of waiting times that fall within each range. For example, the class 0-4 has a frequency of 7, meaning 7 customers waited between 0 to 4 minutes for their oil change.
The number of times a specific value appears in the data is its frequency (f). A variable's distribution is its frequency pattern, or the collection of all conceivable values and the frequencies corresponding to those values.

Geometry I don’t understand
The value of x is -20 and can be calculated using basic proportionality theorem.
What is Basic Proportionality Theorem?The Basic Proportionality Theorem, often known as the Thales Theorem, was developed by the well-known Greek mathematician Thales.
Basic Proportionality Theorem asserted that the ratio of any two related sides is always the same for any two equiangular triangles.
Thales provided the basic proportionality theorem based on this idea (BPT). Similar triangles have introduced this idea before. If two triangles resemble one another, then
The corresponding angles of both triangles are equal.
The corresponding sides of both triangles are proportional to one another.
Since the ratio of other side pair is 1:1, similarly 4x+20 = 3x
20 = 3x-4x
20 = -x
x = -20
Therefore, the value of x is -20
