To maximize the area of a rectangular garden with one side already fenced, Lindsey should allocate the 45 ft of fencing available to form the remaining three sides in a way that makes the two lengths and the width as equal as possible. While an exact numerical answer depends on additional constraints, the guiding principle is that a more square-like configuration will yield the largest area.
Explanation:The question asks what lengths of fencing will produce the largest area for a rectangular garden, given that Lindsey has 45 ft of metal fencing and an existing tall wooden fence will serve as one side of the rectangle. To maximize the area enclosed by a given perimeter, which in this case is the length of the fencing available for three sides of the rectangle (since one side is already in place), it is beneficial to review a principle regarding geometric figures and their areas.
It is a well-established mathematical principle that of all rectangles with a given perimeter, the square has the largest area. However, since one side is already provided and Lindsey is forming only three sides of the rectangle, the problem slightly deviates from forming a perfect square. Nonetheless, the principle that more equidistant lengths result in larger areas can guide us to maximize the area Lindsey can enclose.
Lindsey has 45 ft of fencing to create three sides of a rectangle. For simplicity, let's denote the lengths of the two equal sides as L, and the length of the third side (parallel to the existing fence) as W. Since the total length of fencing is 45 ft, the equation we have is 2L + W = 45. To maximize the area (A = L*W), Lindsey should opt for dimensions where L and W are as close as possible to each other within the constraint of the given perimeter (or in this case, the total length of fencing available).
However, without additional constraints (like the length of the existing fence), a definitive numerical answer cannot be provided. The general advice for Lindsey is to distribute the length of the fencing as evenly as possible between the two lengths and the width she needs to create, thereby approximating a square's dimensions which tends to maximize the enclosed area.

Solve v=1/3bh for b, the base of the cone
Answer:
The base of cone is [tex]b= \frac{3V}{h} [/tex]
Step-by-step explanation:
Given :-
[tex]V =\frac{1}{3} \times b \times h[/tex] .............(1)
we need to solve for the base of cone
Divide both the side by ' h ' in equation (1)
[tex]\frac{V}{h} =\frac{1}{3} \times b[/tex]
Multiply both the sides by 3, in above expression
[tex]3\times \frac{V}{h} = b[/tex]
[tex]b= \frac{3V}{h} [/tex]
Hence, the base of cone is [tex]b= \frac{3V}{h} [/tex]
The Base of the cone whose volume is given is b = 3V/h.
Hence option D.
Since we know that,
A cone is a three-dimensional solid geometric shape having a circular base and a pointed edge at the top.
Here given that,
Base of cone = b
Height of cone = h
Since we also know that,
Volume of Cone = base X height / 3
⇒ V = b X h/3
⇒ 3V = b X h
⇒ b = 3V/h
Thus, the Base of the cone whose volume is given is b = 3V/h.

q-r=r solve for r
Please can someone explain this to me
To solve the equation q-r=r for r, add r to both sides to isolate the variable r. Then, divide both sides by the coefficient of r to find the value of r.
Explanation:To solve the equation q-r=r for r, we want to isolate the variable r on one side of the equation. To do this, we can add r to both sides of the equation:
q - r + r = r + r
This simplifies to:
q = 2r
Next, we can divide both sides of the equation by 2 to solve for r:
q/2 = r
Therefore, the solution is r = q/2.

What are four different ways of representing functions? how can you tell if a relationship is a function?
Functions can be represented verbally, algebraically, graphically, and numerically. A relationship is a function when for every input, there is exactly one output which is described by the vertical line test. Graphs for different types of functions vary in shape.
Explanation:Functions can be represented in four various ways: verbally, algebraically, graphically, and numerically. For instance, verbal representation uses words to describe the function. Algebraically, we express the function via an equation. Graphically, we visually represent the function through graphs. Numerically, we represent the function using a table.
A relationship is a function if for every input, there is exactly one output. In a graph, this corresponds to an instance where a vertical line drawn anywhere on the graph would intersect it at only one point. This is also known as the vertical line test.
Examples of different types of functions graphically could include (a) a linear graph, showing a straight line, (b) a quadratic graph, parabolic in shape, (c) an inverse graph, where y decreases as x increases, and (d) an exponential graph, where the rate of growth is proportional to the function's current value.

How many parallelograms are there?
The sum of two numbers is 64 . the larger number is 18 more than the smaller number. what are the numbers?
Final answer:
To solve the problem, we use a system of equations: x + y = 64 and y = x + 18. The smaller number is found to be x = 23, and the larger number is y = 41.
Explanation:
To find the two numbers where their sum is 64 and the larger number is 18 more than the smaller number, we can set up a system of equations. Let x represent the smaller number and y represent the larger number. We have the following equations:
x + y = 64
y = x + 18
We can substitute the second equation into the first one to solve for x:
x + (x + 18) = 64
2x + 18 = 64
2x = 64 - 18
2x = 46
x = 23
Therefore, the smaller number is 23, and the larger number is:
y = x + 18
y = 23 + 18
y = 41
Hence, the two numbers are 23 and 41.
Triangle XYZ is shown on the coordinate plane below:
Triangle XYZ on the coordinate plane with ordered pairs at X 3, negative 1, at Y 4, negative 4, at Z 1, negative 2
If triangle XYZ is reflected across the line y = 1 to create triangle X'Y'Z', what is the ordered pair of X'?
The ordered pair of [tex]X'[/tex] is [tex](3,3)[/tex]
Explanation
According to the below diagram, the co ordinates of [tex]\triangle XYZ[/tex] are: [tex]X(3, -1), Y(4,-4)[/tex] and [tex]Z(1,-2)[/tex]
The triangle [tex]XYZ[/tex] is reflected across the line [tex]y=1[/tex] to create triangle [tex]X'Y'Z'[/tex]
Distance of the point [tex]X[/tex] from the line [tex]y=1[/tex] is 2 units.
So, the point [tex]X'[/tex] will be also 2 units above the line [tex]y=1[/tex]. As the triangle is reflected across a horizontal line, so the [tex]x[/tex] co-ordinate of the point will remain same.
[tex]y[/tex] co-ordinate of the point [tex]X'[/tex] will be: [tex]y=1+2 =3[/tex]
So, the ordered pair of [tex]X'[/tex] is [tex](3,3)[/tex]

Which of the following is not a pair of similar polygons?
Answer: The answer is the last figure, figure (D). Attached the image.
Step-by-step explanation: We are given four pairs of polygons and we are to select the pair in which the two polygons are not similar.
In the first pair of polygons, the ratio of the corresponding sides will be same as follows:
[tex]\dfrac{2}{\frac{2}{3}}=\dfrac{4}{\frac{4}{3}}=3.[/tex]
So, the polygons are similar.
In the second pair of polygons, the ratio of the corresponding sides will be same as follows:
[tex]\dfrac{2.82}{1.41}=\dfrac{2.24}{1.12}=\dfrac{3}{1.5}=2.[/tex]
So, the polygons are similar.
In the third pair of polygons, the ratio of the corresponding sides will be same as follows:
[tex]\dfrac{1.41}{1.41}=\dfrac{1.12}{1.12}=\dfrac{1.5}{1.5}=1.[/tex]
So, the polygons are similar.
In the fourth pair of polygons, we have
[tex]\dfrac{12}{\frac{4}{3}}=12\times\dfrac{3}{4}=9,[/tex]
and
[tex]\dfrac{4}{\frac{2}{3}}=4\times\dfrac{3}{2}=6\neq 9.[/tex]
So, the polygons are not similar in this case.
Thus, the last figure, attached herewith, is the correct option.
All of the figures are pair of similar polygons
What are similar shapes?Similar shapes have the same shape but may differ in size.
Their corresponding angles are equal, and their corresponding sides are in proportion.
This property allows for resizing through a constant scale factor while maintaining identical angles.
We can test of the polygons are similar by checking the ratio of their corresponding sides are equal.
Fig 1 = 2/2/3 = 3
4/4/3 = 3
therefore the pair of polygons in fig1 are similar.
fig 2 = 3/1.5 = 2
2.82/1.41 = 2
therefore fig2 is a pair of similar polygons.
Therefore, all of the figures are pair of similar polygons

Answer:
D is the correct option.
Step-by-step explanation:
In the given table, the first column is for "hours of training" and the second column is for "Monthly pay".
Now, we have to state the meaning of the term h(40)=1820.
In coordinate system we can write this as (40,1820).
Since, the first column represents "hours of training" and second column is for "Monthly pay". Hence, we can say that for 40 hours of training the monthly payment is $1820.
In other words, if the training attended by the worker is 40 hours, h/she would pay $1820.

For a data set, the mean is 3.17 and the range is 1.4. The data set is transformed by adding 0.5 to each data value. What are the mean and range of the new data set?
a. mean: 3.67; range: 1.9
b. mean: 3.67; range: 1.4
c. mean: 3.17; range: 1.9
d. mean: 3.17; range: 1.4
Adding 0.5 to each value in the data set increases the mean to 3.67 while the range remains at 1.4. Hence, the correct answer is option b.
When a constant is added to each data value in a data set, the mean of the data set increases by that constant, while the range remains unchanged. In this case, adding 0.5 to each data value will increase the mean by 0.5 but the range will stay the same.
Given the original mean: 3.17 and original range: 1.4:
New mean = 3.17 + 0.5 = 3.67
New range = 1.4
Therefore, the correct answer is option b: mean: 3.67; range: 1.4.

An investment is currently worth 2.125 × 10^4 dollars . Ten years ago, the investment was worth 1.25 × 10^3 dollars. How many times greater is the value of the investment today than the value of the investment ten years ago?
The investment today is 17 times greater than it was ten years ago.
To find out how many times greater the value of the investment is today compared to ten years ago, you can divide the current value by the value ten years ago.
So, let's do the calculation:
Current value = 2.125 × 10^4 dollars
Value ten years ago = 1.25 × 10^3 dollars
[tex]\( \text{Times Greater} = \frac{\text{Current Value}}{\text{Value Ten Years Ago}} \)[/tex]
Substitute the values:
[tex]\( \text{Times Greater} = \frac{2.125 \times 10^4}{1.25 \times 10^3} \)[/tex]
To divide these numbers, subtract the exponents:
[tex]\( 10^4 \div 10^3 = 10^{4-3} = 10^1 = 10 \)[/tex]
So,
[tex]\( \text{Times Greater} = \frac{2.125}{1.25} \times 10 = 1.7 \times 10 = 17 \)[/tex]
Therefore, the value of the investment today is 17 times greater than the value of the investment ten years ago.

x= r-h/y
solve for h and r
To solve for h, rearrange the equation to h = r - xy, and to solve for r, rearrange it to r = xy + h. This process involves basic algebraic manipulation to isolate each variable on one side of the equation.
Explanation:The original equation given is x = r - h/y. To solve for h, we need to get h by itself on one side of the equation. First, we can rearrange the equation to isolate h:
Multiply both sides by y to get rid of the fraction: xy = r - h.Move all terms containing h to one side and the rest to the opposite side: h = r - xy.To solve for r, we take the original equation and solve for r explicitly:
First, isolate the term containing r: r = xy + h.Now we have both variables solved in terms of x, y, and each other.
Prove that if a transversal is perpendicular to one of the two parallel lines, it it parallel to the other line
If a transversal is perpendicular to one of the two parallel lines, it is parallel to the other line.
Given:
Parallel lines: AB and CD
Transversal: EF
EF is perpendicular to AB
To prove: EF is parallel to CD
Since EF is perpendicular to AB, ∠AFE = 90°.
Since AB and CD are parallel, corresponding angles are equal: ∠AFE = ∠CFE.
Now, ∠CFE = 90° (since ∠AFE = 90°).
This means EF is perpendicular to CD.
By the converse of the perpendicular transversal theorem, EF is parallel to CD.
