Jack and his friends buy 4 tickets to the show . They also each spend $2 on a drink. They spend $18 in all. Which equation matches the situation.
Answer:
2(x + 4) = $18
Step-by-step explanation:
Let Jack be x
Jack and his friends buy 4 tickets means,
x + 4
Each spend $2 on a drink means,
2 * (x + 4) = 2(x + 4)
Totally, they spend $18
The final equation :
2(x + 4) = $18
Answer:
2x + 4 = 18
Step-by-step explanation:
jack and his friends bought 4 tickets so number 4 is a constant.
each of them spends $2 on a drink
let x be the total number of friends
they collectively spend $18 in all
thus, the equation can be written as,
2x + 4 = 18

Use the graph to answer the question. Graph of polygon ABCD with vertices at 1 comma negative 1, 3 comma negative 5, 7 comma negative 5, 5 comma negative 1. A second polygon A prime B prime C prime D prime with vertices at 1 comma negative 6, 3 comma negative 10, 7 comma negative 10, 5 comma negative 6. Determine the translation used to create the image. 5 units down 5 units up 1 unit down 1 unit up
Answer:
The translation used to create the image from polygon ABCD to polygon A' B' C' D' is 5 units down.
Step-by-step explanation:
You can see this by observing that all of the y-coordinates in A' B' C' D' are 5 units less than their corresponding y-coordinates in ABCD. Specifically, the y-coordinates of the vertices in ABCD are (-1, -5, -5, -1), and the y-coordinates of the vertices in A' B' C' D' are (-6, -10, -10, -6).
Therefore, the vertical shift or translation used to create the image is 5 units down.
Answer:
5 units down.
Step-by-step explanation:
To solve this question, we need to compare the coordinates of the corresponding vertices of the two polygons and see how they change. A translation is a type of transformation that slides a figure by a certain distance and direction without changing its size or shape. The rule of a translation can be written as (x, y) -> (x + h, y + k), where h and k are the horizontal and vertical shifts, we can see that:
A (1, -1) maps to A’ (1, -6), which means x stays the same and y decreases by 5.B (3, -5) maps to B’ (3, -10), which means x stays the same and y decreases by 5.C (7, -5) maps to C’ (7, -10), which means x stays the same and y decreases by 5.D (5, -1) maps to D’ (5, -6), which means x stays the same and y decreases by 5.We can see that all the vertices have the same change in their coordinates: x stays the same and y decreases by 5. This means that the translation used to create the image is 5 units down. The rule of this translation can be written as (x, y) -> (x, y - 5). Therefore, the answer is 5 units down.

1. In the first problem, we need to subtract 1 from 9 since there is an addition:
9 – 1 = 8
Next, divide 8 by 2, and we get:
8 ÷ 2 = 4
This means that x = 4
Finally, check the answer by:
2(4) + 1 = 9
2. In the second problem, we need to subtract 3 from 19 since there is an addition:
19 – 3 = 16
Next, divide 16 by 4, and we get:
16 ÷ 4 = 4
This means that x = 4
Finally, check the answer by:
4(4) + 3 = 19
3. In the third problem, we need to add 2 with 7 since there is subtraction:
2 + 7 = 9
Next, divide 9 by 3, and we get:
9 ÷ 3 = 3
This means that x = 3
Finally, check the answer by:
3(3) – 2 = 7

How far did I travel to reach my destination on each day of my three-day Trip?
a. On Day 1, after traveling 5/8 of the way to the first day's destination, I still had 15 miles left to go before reaching my first destination.
b. On Day 2, after traveling 18 miles, I still had 2/5 of that day's distance left to go before reaching my second destination.
c. On Day 3, after traveling 5/11 of that day's distance, I still had 6 more miles to travel than what I had already traveled that day, before reaching my third destination.
The total distances you traveled to reach your destination on each day of your three-day trip are as follows:
a) Day 1 = 40 miles
b) Day 2 = 30 miles
c) Day 3 = 11 miles.
How the total distances are determined:The total distances are determined using proportions.
Proportion refers to the fractional value of the whole number or quantity.
a) Day 1:
The fractional distance traveled = ⁵/₈
The remaining distance to travel = 15 miles
15 miles = ³/₈ (1 - ⁵/₈)
Proportionately, the total distance = 40 miles (15 ÷ ³/₈)
b) Day 2:
The distance traveled = 18 miles
The remaining distance to travel = ²/₅
The distance traveled = ³/₅ (1 - ²/₅)
³/₅ = 18 miles
Proportionately, the total distance = 30 miles (18 ÷ ³/₅)
c) Day 3:
The distance traveled = ⁵/₁₁
The distance to travel = 6 miles
The distance to travel in fractions = ⁶/₁₁ (1 - ⁵/₁₁)
Proportionately, if 6 miles = ⁶/₁₁, the total distance = 11 miles (6 ÷ ⁶/₁₁)

Error Analysis: A store is instructed by corporate headquarters to put a markup of 67% on all items. An item costing $6 is displayed by the store manager at a selling price of $4. As an employee, you notice that this selling price is incorrect. Find the correct selling price. What was the manager's likely error?
Part 1: The correct selling price is (Round to the nearest dollar as needed.)
Part 2: What was the manager's likely error?
A. The manager set the selling price at the markup.
B. The manager subtracted the markup from the cost instead of adding it.
C. The manager set the selling price at the cost.
D. The manager added the markup to the cost instead of subtracting it.
Answer:
To find the correct selling price, we need to first find the cost of the item plus the markup. We can do this by multiplying the cost of the item by the markup percentage: $6 * 67% = $4.02. However, since the question asks us to round to the nearest dollar, we can round this number down to $4.
Therefore, the correct selling price is $4.
The manager's likely error was that they set the selling price at the cost (option C).
Step-by-step explanation:
The correct selling price is $10 and the manager set the selling price at the markup so option (A) is correct.
What is the percentage?The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.
The percentage is also called the indicating hundredths. Thus, 2% is two-hundredth, which means 2%=2/100=0.02.
As per the given,
Cost of item = $6
Markup = 67%
67% of $6 ⇒ 0.67 x 6 = $4.02
Add the markup in the cost = $6 + $4.02 = $10.02
Round to nearest dollars = $10.2 ≈ $10.
The manager put $4 which is a markup instant of the selling price of $10.
Hence "The correct selling price is $10 and the manager set the selling price at the markup".

See attachment for the graph of the equation.
Step-by-step explanation:
Given equation:
\(y=\dfrac{1}{3}x\)
To complete the table, find the corresponding values of y by substituting each given value of x into the equation.
\(x=6 \implies y=\dfrac{1}{3}(6)=\dfrac{6}{3}=2\)
\(x=12 \implies y=\dfrac{1}{3}(12)=\dfrac{12}{3}=4\)
\(x=18 \implies y=\dfrac{1}{3}(18)=\dfrac{18}{3}=6\)
Therefore the completed table is:
\(\large\begin{array}{|c|c|}\cline{1-2}x&y\\\cline{1-2}6&2\\\cline{1-2}12&4\\\cline{1-2}18&6\\\cline{1-2}\end{array}\)

The system of equations has an infinite number of solutions as the two lines are coincident.
What are equations with infinite solutions?An equation can have infinitely many solutions when it should satisfy some conditions. The system of an equation has infinitely many solutions when the lines are coincident, and they have the same y-intercept. If the two lines have the same y-intercept and slope, they are actually in the same line.
Given here the system of equations are: x+3y=0
12y=-4xor x+3y=0
thus both the equations are identical also their coefficients 1/1 = 3/3 so we can deduce the two lines are coincident with each other and therefore have infinite solutions.
Hence, The system of equations has an infinite number of solutions as the two lines are coincident.

Part A: Calculate the measures of center. Show all work. (2 points)
Part B: Calculate the measures of variability. Show all work. (1 point)
Part C: If you are interested in a smaller class size, which school is a better choice for you? Explain your reasoning
Answer: Please refer below mentioned explanation.
Step-by-step explanation:
Part A:
For Bay Side School: To find the median, we arrange the data in ascending order: 0, 0, 2, 3, 4, 5, 5, 5, 6, 6, 8, 8, 8 There are 13 data points, so the median is the 7th value, which is 5.
To find the mean, we sum up all the data points and divide by the number of data points: Mean = (0 + 0 + 2 + 3 + 4 + 5 + 5 + 5 + 6 + 6 + 8 + 8 + 8) / 13 = 66 / 13 ≈ 5.08
For Seaside School: To find the median, we arrange the data in ascending order: 0, 0, 0, 1, 1, 2, 2, 5, 5, 5, 6, 7, 7, 8, 8 There are 15 data points, so the median is the 8th value, which is 5.
To find the mean, we sum up all the data points and divide by the number of data points: Mean = (0 + 0 + 0 + 1 + 1 + 2 + 2 + 5 + 5 + 5 + 6 + 7 + 7 + 8 + 8) / 15 = 57 / 15 ≈ 3.80
Part B:
For Bay Side School: Range = Maximum value - Minimum value = 8 - 0 = 8
For Seaside School: Range = Maximum value - Minimum value = 8 - 0 = 8
Part C:
Based on the measures of the center, Bay Side School has a higher mean and median compared to Seaside School. This suggests that, on average, Bay Side School tends to have larger class sizes than Seaside School. Therefore, if you are interested in a smaller class size, Seaside School would be a better choice. Additionally, both schools have the same range of 8, indicating that the spread of class sizes is similar between the two schools.

Use the Midpoint Rule with \(n=5\) to estimate the volume obtained by rotating about the y-axis the region under the curve \(y=\sqrt{1+x^3}\), \(0\leq x\leq 1\).
To estimate the volume using the Midpoint Rule with \(\displaystyle n=5\), we need to divide the interval \(\displaystyle 0\leq x\leq 1\) into \(\displaystyle n\) subintervals of equal width. Since \(\displaystyle n=5\), each subinterval will have a width of \(\displaystyle \Delta x=\frac{1-0}{5}=\frac{1}{5}\).
Now, let's calculate the volume using the Midpoint Rule. The formula for the volume obtained by rotating about the y-axis is:
\(\displaystyle V\approx 2\pi \sum _{i=1}^{n}y_{i}\Delta x\)
where \(\displaystyle y_{i}\) represents the value of the function \(\displaystyle y=\sqrt{1+x^{3}}\) evaluated at the midpoint of each subinterval.
First, let's find the midpoints of the subintervals. Since the width of each subinterval is \(\displaystyle \Delta x=\frac{1}{5}\), the midpoint of the \(\displaystyle i\)-th subinterval is given by:
\(\displaystyle x_{i}=\frac{\Delta x}{2}+\left( i-\frac{1}{2}\right) \Delta x=\frac{1}{10}+\left( i-\frac{1}{2}\right) \frac{1}{5}\)
Substituting \(\displaystyle x_{i}\) into the function \(\displaystyle y=\sqrt{1+x^{3}}\), we obtain:
\(\displaystyle y_{i}=\sqrt{1+\left( \frac{1}{10}+\left( i-\frac{1}{2}\right) \frac{1}{5}\right) ^{3}}\)
Now, we can calculate the approximate volume using the Midpoint Rule:
\(\displaystyle V\approx 2\pi \sum _{i=1}^{5}y_{i}\Delta x\)
Substituting the values of \(\displaystyle y_{i}\) and \(\displaystyle \Delta x\) into the formula, we can evaluate the sum and compute the estimated volume.
