Lindsey has 45ft of metal fencing to form 3 sides of a rectangular garden. A tall wooden fence already in place will serve as the fourth side. What lengths of fencing will produce the largest area?
Answers
Area = L x W
From the given scenario, we can deduced that,
L + 2W = 48
Such that L = 48 - 2W.
Substituting this to the equation for area,
Area = (48 - 2W)(W)
Simplifying,
Area = 48W - 2W²
Differentiating and equating to zero,
dArea = 48 - 4W = 0
The value of W from the equation is 12. Hence,
L = 48 - 2W = 48 - 2(12) = 24
The dimensions are:
Length = 24 ft
Width = 12 ft
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.

Which description matches the algebraic expression 45n
A.the sum of a number and 45
B. the quotient of a number and 45
C. the product of a number and 45
D. the difference of a number and 45
Answers
Answer: The correct description is (C). the product of a number and 45.
Step-by-step explanation: We are given to select the correct description that matches the algebraic expression 45n.
Let, 'n' be a number.
Then, the sum of 'n' and 45 is written as (45 + n).
So, option (A) is incorrect.
The quotient of 'n' and 45 is given by [tex]\dfrac{n}{45}~\textup{or}~\dfrac{45}{n}.[/tex]
So, option (B) is incorrect.
The product of 'n' and 45 is
45 × n = 45n, which means 45 times of a number 'n' or n times of 45.
So, option (C) is correct.
The difference of 'n' and 45 is (n - 45) or (45 - n), according as 'n' is greater or 45 is greater.
So, option (D) is incorrect.
Thus, the correct option is (C).
The sum of three numbers is 50. one number is 10 more than the second number it’s also twice the third find the number
Answers
y + 10 = x, solving for y, y = x - 10
x = 2z, solving for z, z = x/2
Substituting for y and z,
x + x - 10 + x/2 = 50
(5/2)x - 10 = 50
(5/2)x = 60
x = (2/5) * 60 = 24
y = x - 10 = 24 - 10 = 14
Z = x/2 = 24/2 = 12
Checking:
x + y + z = 50, 24 + 14 + 12 = 50, 50 = 50. Solution meets the initial constraint.
The three numbers will be 24, 14 and 12 respectively.
What is Equation Modelling?Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.
Given is the sum of three numbers is 50 and first number is 10 more than the second number and it is also twice the third.
Assume that the three numbers are [x] , [y] and [z].
Then, we can write -
x + y + z = 50 ..[1]
x = y + 10 ..[2]
x = 2z ..[3]
Equating Eq [2] and Eq [3], we get -
2z = y + 10
Rearranging the equation above -
y = 2z - 10
Now, for Eq [1], we can write -
2z + z + y = 50
3z + y = 50
3z + 2z - 10 = 50
5z = 60
z = 12
Then, the value of [y] will be -
y = 2 x 12 - 10
y = 24 - 10
y = 14
and
x = 2z = 2 x 12 = 24
Therefore, the three numbers will be 24, 14 and 12 respectively.

What is the slope of a line that is perpendicular to a line whose equation is −2y=3x+7 ?
Enter your answer in the box.
Answers
Answer:
[tex]\frac{2}{3}[/tex] is the Slope of a line that is perpendicular to a given line equation -2y=3x+7
Step-by-step explanation:
We are given here with the equation of the line [tex]-2y=3x+7[/tex] or we can write this equation as [tex]y=\frac{-3}{2}x+\frac{-7}{2}[/tex]
the general equation of the line [tex]y=mx+b[/tex] where m is the slope and b is the y-intercept.
Compare the given equation with general equation we get,
the value of slope(m) [tex]=\frac{-3}{2}[/tex]
The slope of line perpendicular to a line is, [tex]m_{perpendicular}=\frac{-1}{m}[/tex]
Since, the slope of the given line is, m=[tex]\frac{-3}{2}[/tex]
then, [tex]m_{perpendicular}=\frac{-1}{\frac{-3}{2} }[/tex][tex]=\frac{2}{3}[/tex]
Therefore, the slope of a line that is perpendicular to a line whose equation is -2y=3x+7 is, [tex]\frac{2}{3}[/tex]
The slope of the line that is perpendicular to a line whose equation is -2y = 3x + 7 is 2/3.
For lines to be perpendicular to each other, the product of there slopes is equals to negative 1. This can be mathematically represented as follows
m₁ × m₂ = -1
where
m₁ and m₂ are slopes of the lines.
Therefore,
let's find the slope of the equation given
-2y = 3x + 7
divide both sides by -2
y = -3/2 x + 7/2
Using the slope equation model,
y = mx + c
where
m = slope
The slope in our equation will be - 3/2.
Using the first formula for perpendicular lines,
m₁ × m₂ = -1
-3/2 m₁= -1
m₁ = -2/-3
m₁ = 2/3
The slope of the line is 2/3

The statement which is true about the unit price is:
Kitty Kibbles has a higher unit price of $1.50 /pound.Step-by-step explanation:A 16 -pound bag of Kitty Kibbles is $24.00 .i.e.
16 pound cost= $ 24
Hence,
cost of 1 pound= $ (24/16)
= $ 1.50
i.e. unit price of Kitty Kibbles is: $ 1.50
Also,An 8 -pound bag of Feline Flavor is $11.20
i.e. cost of 8 pound of Feline Flavor= $ 11.20
cost of 1 pound of Feline Flavor= $ (11.20/8)

Hence, unit price of Feline Flavor is: $ 1.40
How to solve a multiplication problem with a variable?
Answers
Example Question: 6x + 4 = 22
The goal in this is to get the variable alone and these are the steps how to. What you have to do is subtract 4 from 4 so that you can get 6x alone. But when you subtract 4 from one side, you have to subtract 4 from the other side too which leaves us with 6x = 18. Now, we have to do the opposite of multiplication which is division. So we are going to do 6x divided by 6 and the two sixes cancel each other out. But remember, if you do something to one side you have to do it to the other as well. So we have to do 18/6 which leaves us with the answer.

The correct option is a.
Marta is likely incorrect because her equation has a positive y-intercept, but the scatterplot suggests a negative y-intercept.
Explanation:Marta is likely incorrect because her equation has a positive y-intercept, but the scatterplot suggests a negative y-intercept. The y-intercept is the value of y when x equals zero, so if the scatterplot shows a negative y-intercept, it means that when x is zero, y is negative. However, Marta's equation predicts a positive y value when x is zero, which contradicts the scatterplot.
