Ben can buy 5 notebooks for $6.75 at Store A or 3 notebooks for $4,50 at Store B Which store offers the better value
The store that offers the better value based on the unit rate is Store A.
What is the unit rate?The unit rate is the ratio of one item to the whole item.
The unit rate represents the average of a data set.
It is computed by dividing the total value by the number of units.
The cost of 5 notebooks at Store A = $6.75
The unit rate of notebooks at Store A = $1.35 ($6.75/5)
The cost of 3 notebooks at Store B = $4.50
The unit rate of notebooks at Store B = $1.50 ($4.50/3)
Thus, using the unit rate as the basis of consideration, we can conclude that Store A offers Ben a better value than Store B.

A container of bead contain8 redbead, 7 yellow bead , and green bead. A bead will be drawn from the baket and replace 60 time what i a reaonable prediction for the number of time green or red bead i drawn
A reasonable prediction for the number of times a green or red bead will be drawn from the container of beads, after being replaced 60 times, would be 42.
A reasonable prediction for the number of times a green or red bead will be drawn from the container of beads, after being replaced 60 times, would be close to the proportion of green or red beads in the container. The container has 8 red beads and 6 green beads out of a total of 8 + 7 + 6 = 21 beads. The proportion of green or red beads is (8 + 6) / 21 = 14/21.
We can use this proportion to predict the number of times a green or red bead will be drawn from the container. By multiplying the proportion of green or red beads by the number of times the bead is replaced, we get (14/21) * 60 = 42.
In this scenario, we are using the concept of probability and proportion. The probability of drawing a green or red bead is 14/21, and by multiplying it by the number of trials (60), we get the expected number of times the green or red bead will be drawn. This concept is used in statistics and probability to make predictions based on the available data. It is important to note that this is only a prediction and actual results may vary.

On a map two points are 7cn apart the map has a scale of 1:10000 what is the actual distance
Answer:
700 meters.
Step-by-step explanation:
The actual distance between the two points can be determined by using the scale of the map. If the scale of the map is 1:10,000, it means that one unit of measurement on the map represents 10,000 units of the same measurement in reality.
Therefore, if the distance between the two points on the map is 7cm, the actual distance is 7cm * 10,000 = 70,000cm or 700 meters.
So, the actual distance between the two points is 700 meters.

Percentage of unemployment is 58.33 % in the total household of 60,000.
What is Percentage?Although the abbreviations "pct.", "pct.", and "pct." are also used, the percent symbol, "%," is most commonly used. A percentage is a number with no dimensions and no standard measurement.
The English word "percentage" is derived from the Latin phrase "per centum," which means "by the hundred." Percentages are fractions with a numerator of 100. In other words, it is a relationship in which the total value is always assumed to be one hundred.
Percentage calculation is the process of determining a percentage of a whole in terms of 100. There are two ways to calculate a percentage:
Using the unitary approach
by adjusting fraction's denominator to 100.
It should be noted that when the denominator is not a factor of 100, the second technique of percentage calculation isn't applied. In these situations, we employ the unitary technique.
Total number of household is 60000
Total number of household which is unemployed is 35000
Percentage of unemployment = (35000/60000) * 100 = 58.33 %

How to Solve Algebra Word Problems?We are told that the main street location raised $50 more than the Back Street location. Thus;
m.s = b.s + 50 ------(eq 1)
The Washington Street location raised $50 more than half the amount raised at the Back Street location. Thus;
w.s = ¹/₂b.s + 50 -------(eq 2)
Total raised = $600. Thus;
m.s + b.s + ws = 600 -------(eq 3)
-----------------------------
Plug in b.s + 50 for m.s and ¹/₂b.s + 50 for w.s in eq 3 to get;
(b.s + 50) + (¹/₂b.s + 50) + b.s = 600
Solve for b.s;
b.s + ¹/₂b.s + b.s + 50 + 50 = 600
(5/2)b.s + 100 = 600
(5/2)b.s = 500
b.s = $200 (amount raised by Back Street location)
m.s = b.s + 50

Solve the system of equations below. Enter the value of the y value from your solution (in the case of a fraction or decimal solution, round your answer to the nearest tenth).
According to your solution of the given system of equations, the value of y is 7.
What are Systems of equations?Simultaneous equations, a system of equations Two or more equations in algebra must be solved jointly (i.e., the solution must satisfy all the equations in the system). The number of equations must match the number of unknowns for a system to have a singular solution.
There are four methods for solving systems of equations: graphing, substitution, elimination, and matrices.
Given a system of equation y = 2x + 11 and 3x + 2y = 8
From equation 1 we will substitute the value of y in the form of x in equation 2
=> 3x + 2(2x + 11) = 8
=> 3x + 4x + 22 = 8
=> 7x = 8 - 22
=> 7x = -14
=> x = -2
Substitute this value in equation 1
=> y = 2* -2 +11
=> y = -4 + 11
=> y = 7
therefore, the value of the y is 7 from your solution of the system of equations given.

Pattern rule equation:
A pattern rule equation is a mathematical formula that describes how a pattern is created. It defines the relationship between the position number (p) and the number of tiles (n) in the pattern.
The pattern rule equation is a useful tool to predict the number of tiles in a certain position, for example, position 26 as I mentioned in my previous answer.
It's also useful to predict the total number of tiles in a pattern or to identify the position number of a specific number of tiles.
In the pattern rule equation n = 53p, n is the number of tiles and p is the position number. To find the number of tiles in position 26, we can substitute 26 for p in the equation:
n = 53p
n = 53(26)
n = 1378
