In a fraction, the common denominator refers to the lowest common multiple of the denominators of the fractions. If you use the common multiple from part A as the common denominator, the models in the example will be different and at the same time the same.
A common multiple is the product of two or more factors that are common. In other words, it is a number that is a multiple of two or more integers.
Let's take an example of finding the common multiple of 6 and 8:
The multiples of 6 are: 6, 12, 18, 24, 30, 36, 42, 48, ...
The multiples of 8 are: 8, 16, 24, 32, 40, 48, ...
Therefore, the common multiples of 6 and 8 are: 24, 48, 72, 96, 120, 144, ...
The models would be different because the common denominator is the lowest common multiple of the denominators of the fractions. If we use the common multiple as the denominator, the size of the models may change.
Let's take an example:
Suppose we have two fractions, 1/2 and 2/3. The denominators are 2 and 3. The common multiple is 6.
If we use 6 as the common denominator, the fractions become:
1/2 = 3/6 (we multiplied the numerator and denominator by 3)
2/3 = 4/6 (we multiplied the numerator and denominator by 2)
The models would be different because the sizes are based on the denominators of the fractions. If we change the denominator, the size of the model may also change.
The models would be the same because they represent the same fractions.
Even though the size of the model may change, the fractions still represent the same value.
In the above example, 1/2 and 3/6 represent the same value, and 2/3 and 4/6 represent the same value.
Therefore, the models are still representing the same value even though they may be different in size.

A grocer mixes together some cashews costing $8 per kilogram with some Brazil nuts costing
$10 per kilogram. The grocer sold 12 kg if the mixture for $8.50 per kilogram. How many
kilograms of cashews were in the mixture the grocer sold?
I know the answer is 9 but how do i get that?
9 kilograms of cashews were in the mixture the grocer sold.
To solve the given problem, let x represent the number of kilograms of cashews.
Hence, the number of kilograms of Brazil nuts would be (12 - x) as the grocer sold 12 kg of the mixture.
Therefore, the cost of the cashews at $8 per kilogram is 8(x)
and the cost of the Brazil nuts at $10 per kilogram is 10(12 - x).
Hence, the cost of the mixture at $8.50 per kilogram is:
8.5*(12) = 8(x) + 10(12 - x)
We solve this equation for x:
102 = 8(x) + 120 - 10(x)

For her phone service, Linda pays a monthly fee of $27 and she pays an additional $0.07 per minute of use The least she has been charged in a month is $129.13What are the possible numbers of minutes she has used her phone in a month?
Therefore, the possible numbers of minutes Linda has used her phone in a month are 1459 minutes or more.
To determine the possible number of minutes Linda has used her phone in a month, we can set up an equation based on the given information.
Let's assume the number of minutes Linda has used her phone in a month is represented by 'm'.
The total charge for the phone service consists of the monthly fee of $27 plus the additional charge of $0.07 per minute:
Total charge = $27 + $0.07 * m
According to the given information, the least amount Linda has been charged in a month is $129.13. So we can set up the following equation:
$27 + $0.07 * m ≥ $129.13
Now we can solve this equation to find the possible range of values for 'm'.
$0.07 * m ≥ $129.13 - $27
$0.07 * m ≥ $102.13
m ≥ $102.13 / $0.07
m ≥ 1459
Therefore, the possible numbers of minutes Linda has used her phone in a month are 1459 minutes or more.

Three vertices of parallelogram WXYZ are W(-5,2), X(2,4), and Z(-7, -3). Find the coordinates of vertex Y
The coordinates of Y are (-1,0). Answer: The coordinates of vertex Y are (-1,0).
To find the coordinates of vertex Y of parallelogram WXYZ whose coordinates are given, we need to use the properties of a parallelogram.
A parallelogram is a quadrilateral in which opposite sides are parallel and congruent.
It means the distance between points W and X is equal to the distance between points Y and Z.
W(-5,2), X(2,4), Y(a,b), and Z(-7,-3).
Therefore, the length of side WX is given as,
WX = √ [(2 - (-5))²+ (4 - 2)²]
= √(49 + 4) = √53. ..(1)
As opposite sides of parallelogram are parallel, XY will have the same slope as WZ. The slope of line WZ is given as
(2 - (-3))/(-5 - (-7)) = 5/2.
Therefore, the slope of XY is also 5/2.
(a, b) is on line XY. The equation of line XY can be written as
y - b = 5/2(x - a) ...(2)
It is given that the length of side WZ is equal to the length of side WX. Therefore,
WZ = WX = √53.
Distance WY can be found using the distance formula as follows:
WY² = WZ² - ZY²WY² = 53 - (b + 3)² ...(3)
Similarly, distance XY can be found as,
XY²= WX²- WY²XY²
= 53 - (a - 2)² - (b - 4)² ...(4)
By solving equations (2), (3), and (4) for a and b, we can get the coordinates of Y.a = -1, b = 0
Therefore, the coordinates of Y are (-1,0). Answer: The coordinates of vertex Y are (-1,0).

Name two characteristics of nonvertical lines that make slope-intercept form (y = mx + b) a good choice when writing an equation for this type of line.
Two characteristics of nonvertical lines that make slope-intercept form (y = mx + b) a good choice when writing an equation for this type of line are:
Slope: The slope of a line represents the rate of change between the y-coordinates and x-coordinates. In slope-intercept form, the slope (m) is explicitly represented as a coefficient of x. This allows us to easily determine the steepness and direction of the line. By knowing the slope, we can understand how the line is changing and make predictions about its behavior.
y-intercept: The y-intercept (b) in slope-intercept form represents the value of y when x is equal to zero. It indicates the point where the line crosses the y-axis. Having the y-intercept explicitly stated in the equation allows us to quickly identify the starting point of the line and understand its initial position on the coordinate plane.
By having both the slope and y-intercept explicitly defined in the equation, slope-intercept form provides valuable information about the line's behavior, direction, and starting position. It simplifies the process of graphing and understanding the line's characteristics.

A cylinder and a cone have the same height and the same base areas. If the volume of the cylinder is 66 cubic inches, what is the volume of the cone? (Use 3. 14 for Pi)
Answer:
The volume of the cone is 22 cubic inches.
Step-by-step explanation:
To find the volume of the cone, we need to use the formula for the volume of a cone:
Volume of a cone = (1/3) * π * r^2 * h
Given that the height and base area of the cylinder and cone are the same, we can assume that the radius of the cylinder's base is equal to the radius of the cone's base.
We know that the volume of the cylinder is 66 cubic inches, so we can set up the equation:
66 = π * r^2 * h
To find the volume of the cone, we need to express its height in terms of the radius of the cylinder's base. The height of the cone will be equal to the height of the cylinder.
Now, let's solve for h in terms of r using the given information:
66 = π * r^2 * h
h = 66 / (π * r^2)
Substituting this value of h into the volume formula of the cone:
Volume of the cone = (1/3) * π * r^2 * (66 / (π * r^2))
Volume of the cone = (1/3) * 66
Volume of the cone = 22

How much did the baker pay for the 8 trays of brand
The baker paid approximately R15.08 for each tray of Brand A.
Understanding Word ProblemLet:
x = price of each tray of Brand A
y = price of each tray of Brand B
Given that the prices are in the ratio 4:7, we can write the equation:
x/y = 4/7
To find the individual prices of Brand A and Brand B, we can introduce a constant k:
x = 4k
y = 7k
The total cost of 8 trays of Brand A (8x) and 6 trays of Brand B (6y) is R279.45:
8x + 6y = 279.45
Substituting the expressions for x and y:
8(4k) + 6(7k) = 279.45
32k + 42k = 279.45
74k = 279.45
Dividing both sides by 74:
k = 279.45 / 74
k ≈ 3.77
Now we can find the price of each tray of Brand A:
x = 4k ≈ 4 * 3.77 ≈ R15.08
Therefore, the baker paid approximately R15.08 for each tray of Brand A.

Given a baseball league has a rule that when one team is winning by at least 10 runs the game is over after the fifth inning, and the home team has 7 more runs than the visiting team. We are to determine how many more runs the home team must score for the game to end after the fifth inning if the visiting team does not score.
In the game of baseball, the number of runs scored by each team is known as the scoreline. The home team has a scoreline of X while the visiting team has a scoreline of X - 7, where X is a positive integer and X - 7 is the scoreline of the visiting team.
Since the game is to be over after the fifth inning, we need to determine the number of runs the home team will need to score to have a 10 run difference or more after the fifth inning. Let's analyze two different scenarios, the first being if the home team were to score one run, and the second scenario being if the home team were to score two runs.
The home team scoreline would be X + 1 in the first scenario and X + 2 in the second scenario. In both cases, the visiting team does not score any additional runs. Thus, the scoreline of the visiting team remains X - 7 in both scenarios.
The difference in the scoreline after the fifth inning would be as follows in the two cases, respectively: (X + 1) - (X - 7) = 8(X + 2) - (X - 7) = 9. From the above calculations, we can see that the home team must score at least nine more runs for the game to end after the fifth inning if the visiting team does not score.
This solution means that if the home team scores nine more runs, then the visiting team will not be given an opportunity to bat in the sixth inning and beyond, because the difference in the scoreline will be at least 10 runs after the fifth inning.

To solve this problem, we can set up an equation based on the volume of lemon juice in the mixture:
Let's assume Milo needs to add x gallons of 100% lemon juice.
The total volume of the final mixture is given as 4 gallons, and it should be a 50% lemon juice and 50% lime juice mixture.
The initial mixture contains 20% lemon juice, which means it contains 20% of 4 gallons = 0.2 * 4 = 0.8 gallons of lemon juice.
So, the equation becomes:
0.8 gallons (initial lemon juice) + x gallons (additional 100% lemon juice) = 0.5 * 4 gallons (final lemon juice)
Simplifying the equation:
0.8 + x = 2
Subtracting 0.8 from both sides:
x = 2 - 0.8
x = 1.2
Therefore, Milo needs to add 1.2 gallons of 100% lemon juice to make 4 gallons of the 50% lemon/50% lime juice mixture.

Karen drew a plan for a rectangular piece of material that she will use for a blanket. Three of the vertices are (−1.3,−3.1), (−1.3,1.2), and (1.1,1.2). What are the coordinates of the fourth vertex?
The coordinates of the fourth vertex are (1.1, -3.1).
We know that a rectangular piece of material has two pairs of parallel sides and four right angles. Therefore, we can calculate the distance between two opposite sides by using the distance formula. The two sides that are parallel to the x-axis have the same y-coordinate, and the two sides parallel to the y-axis have the same x-coordinate.
Thus, the distance between opposite sides is given by the difference between the x-coordinates or the difference between the y-coordinates. The x-coordinates of the vertices are −1.3, −1.3, and 1.1. So the difference between them is 1.1 − (−1.3) = 2.4. The y-coordinates of the vertices are −3.1, 1.2, and 1.2. So the difference between them is 1.2 − (−3.1) = 4.3. The fourth vertex is located at the point with an x-coordinate of 1.1 and a y-coordinate of −3.1. Therefore, the coordinates of the fourth vertex are (1.1, -3.1).

£360 is shared between Abby, Ben, Chloe and Denesh. The ratio of the amount Abby gets to the amount Ben gets is 2 : 7 Chloe and Denesh each get 1. 5 times the amount Abby gets. Work out the amount of money that Ben gets. (4)
The amount of money that Ben gets is £140.
Let's denote the amount Abby gets as 2x. Since the ratio of Abby's amount to Ben's amount is 2:7, the amount Ben gets can be represented as 7x.
Chloe and Denesh each get 1.5 times the amount Abby gets, which means they each get 1.5 * 2x = 3x.
The total amount shared between Abby, Ben, Chloe, and Denesh is £360. So we can write the equation: 2x + 7x + 3x + 3x = £360.
Simplifying the equation, we have: 15x = £360.
Dividing both sides by 15, we find that x = £24.
Substituting x back into the equation for Ben's amount, we get: Ben's amount = 7x = 7 * £24 = £168.
Therefore, Ben gets £140.

What is the value of n when 3/5 of n is 27? Enter answer in the box
n = 45 satisfies the equation, and it is the value that makes 3/5 of n equal to 27. The value of n can be determined by setting up an equation based on the given information that 3/5 of n is equal to 27.
By solving the equation, we can find the value of n. Let's set up the equation based on the given information:
(3/5) * n = 27
To solve for n, we need to isolate n on one side of the equation. We can do this by multiplying both sides of the equation by the reciprocal of 3/5, which is 5/3:
n = 27 * (5/3)
Simplifying the right side of the equation:
n = (27 * 5) / 3
n = 135 / 3
n = 45
Therefore, the value of n is 45. We can confirm this by substituting n = 45 back into the equation:
(3/5) * 45 = 27
(3/5) * 45 = 135/5 = 27
