add 24, 22, and 6. for the ratio see if they all match up to the prices to the number of pairs of jeans. then just look at ur table for jeans and see which one has the greatest value. by equivalent it means are they the same as the one that is greatesst on table D and see if any of them are equivalent to the one you chose for E. for F all you would have to do is divide the number in A by 7. then just look at ur previous tables and find ur ratio
Tim will pay the same amount whether buying locally or online, without considering sales tax. The price per jeans remains constant in both local and online stores. When sales tax is applied, the ratio of number of pairs to price changes, increasing the cost per pair.
Each part of the problem step by step:
Part A:
Tim wants to buy three pairs of jeans. He can either purchase them at a local store for $24 each or online for $22 each plus a $6 shipping fee per order.
Part B:
For the local store, the ratio of the number of pairs of jeans (3) to the cost per pair ($24) is 3/24 = 1/8.
Part C:
The ratios calculated in Part B are not equivalent. As the number of pairs of jeans increases at the local store, the cost decreases proportionally.
Part D:
For the online store, the ratio of the number of pairs of jeans (3) to the cost per pair ($22) plus the shipping fee ($6) is 3/(22+6) = 3/28.
Part E:
The ratios calculated in Part D are not equivalent either. As the number of pairs of jeans increases online, the cost per pair decreases due to the shipping fee.
Part F:
To find the cost of jeans at the local store with a 7% sales tax, multiply the cost by 1.07 (since it's an increase of 7%). The table can be filled accordingly.
Part G:
Now, calculate the ratio of the number of pairs of jeans (3) to the cost with sales tax for each row in the table.
Part H:
The ratios calculated in Part G are not equivalent. The relationship between the number of pairs of jeans and the cost with sales tax applied at the local store shows that as the number of pairs increases, the cost with tax also increases proportionally.

The price of a necklace was increased by 20% to ?186. What was the price before the increase?
Answer:
148.8
Step-by-step explanation:
The original price of the necklace before the 20% increase was approximately £155 (£186 / 1.20).
To find the original price of the necklace before the 20% increase, we can use the formula:
Original Price = Final Price / (1 + Percent Increase)
Given that the final price is £186 and the increase is 20%, we substitute these values into the formula:
Original Price = £186 / (1 + 0.20)
Calculating inside the parentheses first:
1 + 0.20 = 1.20
Now, divide the final price by 1.20:
Original Price = £186 / 1.20 ≈ £155
So, the original price of the necklace before the increase was approximately £155.

5 times a number, subtracted from six, is triple the number
Final answer:
The algebraic equation based on the statement '5 times a number, subtracted from six, is triple the number' is 6 - 5x = 3x. Solving for 'x' gives us x = 3/4.
Explanation:
The student's question involves creating an algebraic equation based on a verbal statement. To translate the statement '5 times a number, subtracted from six, is triple the number' into an equation, let's use 'x' to represent the unknown number. The statement can be written as: 6 - 5x = 3x. To solve for 'x', we need to get all terms involving 'x' on one side and constants on the other. Here's how you can do it:
Add 5x to both sides of the equation to get: 6 = 3x + 5x
Combine like terms: 6 = 8x
Divide both sides by 8 to get the value of x: x = 6/8
Simplify the fraction: x = 3/4
Therefore, the number in question is 3/4.
What is 858 divided by 57 using partial quotients
Answer:
The answer will be: [tex]15 + \frac{3}{57}[/tex]
Step-by-step explanation:
In Partial quotients method, first we will subtract an easy multiple of the divisor from the dividend. Then repeat the subtraction until the remainder is less than the divisor. Finally, we need to add up all the multiples of the divisor to find the quotient of the division.
Here, dividend is 858 and divisor is 57.
[tex]57)\overline{858}[/tex]
- 570 × 10
288
- 285 × 5
3
So, the quotient of the division will be: [tex](10+5)=15[/tex] and the remainder is: 3
We can write the answer as: [tex]15 + \frac{3}{57}[/tex]
Consider these two histograms representing two sets of data with 10 observations each. Which of the following is true?
A. The means are equal and the standard deviation of Plot 1 is smaller than the standard deviation of Plot 2.
B. The means are equal and the standard deviations are equal.
C. The mean and standard deviation of Plot 2 are larger than the mean and standard deviation of Plot 1.
D. The means are equal and the standard deviation of Plot 1 is larger than the standard deviation of Plot 2.
Answer:
The answer is D . The means are equal and the standard deviation of Plot 1 is larger than the standard deviation of Plot 2.
Step-by-step explanation:
The histogram gives you information about the number of times a specific number appears on your sample. Then you can construct your sample looking at each histogram. For example in Plot 1 the value -2 appears two times. If you this, you obtain the following samples:
Plot 1: -2, -2, -1, -1, 0, 0, 1, 1, 2, 2
Plot 2: -2, -1, -1, 0, 0, 0, 0, 1, 1, 2
If you calculate the means by adding and dividing by the number of obs you find equal means (0) because the data is centered around 0. ( no deviations to left or right).
Now the standard deviation (sd) can be infered in the histogram. The sd measures the distance around the mean of the data. When data is concentrated very close to the mean, the sd is lower as in Plot 2 (More points are 0 or around zero in Plot 2). In plot 1 your points are farther apart from the mean of zero so the sd is higher.

One way that a company can raise money for expansion is to sell stock. When you buy a share of a company's stock, you become a shareholder, or part owner, of that company. The cost of a share is often represented in points, where each points represents one dollar. When a stock gains points, its shares increase in value, and when a stock loses points, its shares decrease in value. For instance, if a stock gains three points one day, each share of its stock is worth three dollars more than it was the day before. Positive decimal numbers are used to represent gains, and negative decimal numbers are used to represent losses.
On Monday, the closing value of a share of stock in Company ABC, was 74.01. On Tuesday, it closed at 73.67, and on Wednesday, it closed at 74.32. On Thursday, the change in stock value was -1.48.

write all of the digita that can rwplace each 735<7 ■ 4<761
The digits 4 and 5 can replace the box in order to make the inequality true.
Any digits larger than 5 or less than 4 will not make it true.
Suppose we used 3.
735 is not greater than 734, and so the inequality would be false.
Now let's suppose we used 6.
764 is not less than 761.
A list of digits that can replace the given expressions 735<7 and 4<761 has been provided.
Explanation:The provided question asks for a list of numbers that can replace the expressions 735<7 and 4<761. To find the numbers that can replace these expressions, we need to identify the digits in the list provided that satisfy the conditions. Let's go through each digit in the list and determine if they can replace the expressions:
For 735<7, we can see that the digits 664, 695, 696, 698, 707, 712, 713, 721, 723, 725, 761, 762, 763, 767, 775, 778, 805, 833, 889, 893, 899, 903, 909, 921, and 923 are all greater than 735 and thus satisfy the condition.For 4<761, the digits 136, 140, 178, 190, 205, 215, 217, 218, 232, 234, 240, 255, 270, 275, 290, 301, 303, 315, 317, 318, 326, 333, 343, 349, 360, 369, 377, 388, 391, 392, 398, 400, 402, 405, 408, 422, 429, 450, 475, and 512 are all less than 761 and satisfy the condition.Therefore, the list of digits that can replace 735<7 are: 664, 695, 696, 698, 707, 712, 713, 721, 723, 725, 761, 762, 763, 767, 775, 778, 805, 833, 889, 893, 899, 903, 909, 921, 923. The list of digits that can replace 4<761 are: 136, 140, 178, 190, 205, 215, 217, 218, 232, 234, 240, 255, 270, 275, 290, 301, 303, 315, 317, 318, 326, 333, 343, 349, 360, 369, 377, 388, 391, 392, 398, 400, 402, 405, 408, 422, 429, 450, 475, and 512.

In math what does it mean by Define the varible?
Final answer:
To define the variable in mathematics means to assign symbols to represent quantities that can take various values, either as numerical variables measurable in the same units or as categorical variables for classification purposes. This allows for the exploration of relationships and predictions of outcomes.
Explanation:
In mathematics, the term 'define the variable' refers to the process of assigning a symbol, typically a letter such as X or Y, to represent a quantity that can take on various values. Variables can be of different types, such as numerical variables which represent values measurable in the same units like time in hours or weight in pounds, and categorical variables which classify individuals or items into categories, such as political affiliation.
For example, in the equation of a line y=mx+b, x and y are variables with x usually representing the independent variable plotted along the horizontal axis, and y as the dependent variable plotted on the vertical axis. The variable m represents the slope of the line, and b represents the y-intercept, or the point where the line crosses the y-axis. By defining each variable, a mathematician or an economist can explore the relationship between quantities and predict outcomes.
An example in statistics would be letting X represent the number of children in a family, making it a numerical variable, where each specific number of children would be represented by a lowercase x (0, 1, 2, 3, etc.). Conversely, if Y represents someone's political party, each category (Republican, Democrat, Independent, etc.) is an example of a categorical variable, which does not make sense to average mathematically like numerical variables.
How many pounds of coffee worth $9 a pound should be added to 10 pounds of coffee worth $3 a pound to get a mixture worth $7 a pound
Identify the property that justifies the statement.
∠XYZ≅∠PDQ and ∠PDQ≅∠ABC, so ∠XYZ≅∠ABC.
Answer: Transitive property of Equality.
Therefore if ∠XYZ≅∠PDQ and ∠PDQ≅∠ABC then by transitive property of equality we have ∠XYZ≅∠ABC.
The law of transitivity tells that if a equals to b and b equals to c then a equals to c.
For example If Jane has same height of Susan and Susan has same height of Tina then Jane has same height of Tina.
The statement "∠XYZ ≅ ∠PDQ and ∠PDQ ≅ ∠ABC, so ∠XYZ ≅ ∠ABC" is justified by the Transitive Property of Equality, which indicates that the congruence of the first and third angle is established through their mutual congruence to the second angle.
Explanation:The property that justifies the statement "∠XYZ ≅ ∠PDQ and ∠PDQ ≅ ∠ABC, so ∠XYZ ≅ ∠ABC" is the Transitive Property of Equality. This property states that if a first thing is equal to a second thing, and the second thing is equal to a third thing, then the first thing is also equal to the third thing.
In the context of angles, if ∠XYZ is congruent to ∠PDQ, and ∠PDQ is congruent to ∠ABC, then by the Transitive Property, ∠XYZ must be congruent to ∠ABC.
What can the zeros and intercepts of a quadratic function tell you about real world relationships?
Suppose, we are given a function

Application of Zeros:
we know that
zeros are x-intercepts
We know that zeros are values of x for which f(x)=0
and it has very wide application
It is extremely useful in real world applications such as finance, astronomy, geology, architecture, or physics
For exp:
[tex]h(t)=-16t^2 + 96t + 112[/tex]
Zeros will help us to find time at which ball reaches to ground
so, we set h(t)=0
and then we can solve for t
value of t are zeros
Application of y-intercept:
we know that y-intercepts are values of y at which x=0
It's application can be population , finance and physics etc
For exp:
[tex]h(t)=-16t^2 + 96t + 112[/tex]
we can find initial height of object after plugging t=0

A moving company has a truck filled for deliveries to four different sites. If the order of the deliveries is randomly selected what is the probability that is the shortest route?
As there are 4 different sites so we have 4! possible arrangements to choose from so it becomes = [tex]4\times3\times2\times1=24[/tex]
And there will be only 1 shortest route out of these.
So the probability that the route selected is the shortest route becomes = [tex]\frac{1}{24}[/tex]
The question involves finding the probability of randomly arranging deliveries to four sites such that the arrangement corresponds to the shortest route. With 24 possible arrangements, only one of which constitutes the shortest route, the probability is 1/24.
Explanation:This question involves the concept of permutations in probability. If delivery sites are being randomly selected, there are 4! (4 factorial) possible sequences for the deliveries, i.e., 4*3*2*1 = 24 different routes.
Assuming that only one of these combinations constitutes the shortest route, the probability of randomly selecting the shortest route is therefore 1 out of 24. To obtain this, you divide the number of favorable outcomes (1 - because there's only one shortest route) by the total outcomes (24 - from 4 factorial).
So, "the probability of selecting the shortest route randomly is 1/24".

You originally had 30 canicas in your collection.
Let's denote the total number of canicas in your collection as C
According to the information provided:
1. Tales received 1/5 of the total:
Tales received [tex]\( \frac{1}{5} \)[/tex] of C, which can be expressed as [tex]\( \frac{1}{5} \times C \).[/tex]
2. You received 1/3 of the rest:
After giving Tales his share, there are [tex]\( \frac{4}{5} \)[/tex] of the canicas left. You received [tex]\( \frac{1}{3} \)[/tex] of this remaining amount. So, your share is [tex]\( \frac{1}{3} \times \frac{4}{5} \times C \)[/tex].
3. Pitagórica received the remaining 16 canicas:
After Tales and you received your shares, Pitagórica received the remaining canicas, which is given as 16 canicas.
Now, we can set up an equation to represent this situation:
[tex]\[ \frac{1}{5} \times C + \frac{1}{3} \times \frac{4}{5} \times C + 16 = C \][/tex]
Now, let's solve for C:
[tex]\[ \frac{1}{5}C + \frac{4}{15}C + 16 = C \][/tex]
Combine the terms with C:
[tex]\[ \frac{3}{15}C + \frac{4}{15}C + 16 = C \][/tex]
Combine the terms on the left side:
[tex]\[ \frac{7}{15}C + 16 = C \][/tex]
Subtract [tex]\( \frac{7}{15}C \)[/tex] from both sides:
[tex]\[ 16 = \frac{8}{15}C \][/tex]
Now, solve for C:
[tex]\[ C = \frac{15}{8} \times 16 \][/tex]
[tex]\[ C = 30 \][/tex]
Therefore, you originally had 30 canicas in your collection.

A recipe for modeling clay requires 1/3 cup of salt. how many recipes of salt can carla make with 7 3/4 cups of salt
Answer:
- The error is: [tex](\frac{31}{4})(\frac{1}{3})[/tex]
- The correct solution is: [tex]\frac{93}{4}=23^{\frac{1}{4}}[/tex] (Carla can make approximately 23 recipes with the clay).
Step-by-step explanation:
1. Carla must divide [tex]\frac{31}{4}[/tex] ÷ [tex]\frac{1}{3}[/tex] as following:
- Take the reciprocal of [tex]\frac{1}{3}[/tex].
- Multiply the numerators and the denominators.
Then:
[tex](\frac{31}{4})(\frac{1}{3})=\frac{(31)(3)}{(4)(1)}=\frac{93}{4}[/tex]
2. As a mixed number:
[tex]\frac{93}{4}=23^{\frac{1}{4}}[/tex]
3. Therefore, Carla can make approximately 23 recipes with the clay.
Carla can make 23 full modeling clay recipes with 7 3/4 cups of salt, with a quarter cup of salt remaining.
To find out how many recipes of modeling clay Carla can make with 7 3/4 cups of salt, we need to divide the total amount of salt she has by the amount required for one recipe. Since one recipe requires 1/3 cup of salt, we will perform the following division: 7 3/4 divided by 1/3.
To simplify this, first, convert 7 3/4 to an improper fraction, which is (7 × 4 + 3)/4, or 31/4. Now, dividing by a fraction is the same as multiplying by its reciprocal. Therefore, we multiply 31/4 by the reciprocal of 1/3, which is 3/1.
31/4 × 3/1 = 93/4, which simplifies to 23 1/4.
This means Carla can make 23 full recipes with a little salt left over.
