The area of a rectangular picture frame is 4 3/8 square inches. The length of the frame is 1 2/5 inches. Find the width of the frame
The width of the rectangular frame is 3 1/8 inches.
What is the width?It should be noted that the area of a rectangular picture frame is 4 3/8 square inches and the length of the frame is 1 2/5 inches.
The area of a rectangle is:
= Length * Width
Therefore, the width will be:
= Area / Length
= 4 3/8 ÷ 1 2/5.
= 4.375 / 1.4
= 3.125 or 3 1/8.
The width is 3 1/8 feet.

In the given parallelogram ABCD:
CD=5x-18
BC=3x-6
AB=2x+12
From the properties of parallelogram: The opposite sides of parallelogram are equal
Pair of opposite sides are:
AB & CD
BC & DA
Opposite sides are equal:
[tex]\begin{gathered} AB=CD \\ 2x+12=5x-18 \\ 5x-2x=12+18 \\ 3x=30 \\ x=\frac{30}{3} \\ x=10 \end{gathered}[/tex]x = 10
Substitute the value of x = 10 in the expression of BC
BC = 3x - 6
BC = 3(10) - 6
BC = 30 - 6
BC = 24
Opposite sides are equal: BC = DA
BC = 24 = DA
DA = 24
Answer: DA = 24

Answer
Maximum area = 4900 m²
Step-by-step explanation
1.4.1 The perimeter of a rectangle is calculated as follows:
[tex]P=2(l+w)[/tex]where l is the length and w is the width of the rectangle.
Substituting P = 280 m, l = 2x meters, and w = y meters, and solving for y:
[tex]\begin{gathered} 280=2(2x+y) \\ \frac{280}{2}=\frac{2(2x+y)}{2} \\ 140=2x+y \\ 140-2x=2x+y-2x \\ 140-2x=y \end{gathered}[/tex]The area of a rectangle is calculated as follows:
[tex]A=l\cdot w[/tex]Substituting l = 2x and w = y = 140 - 2x:
[tex]\begin{gathered} A=2x(140-2x) \\ A=2x(140)-2x(2x) \\ A=280x-4x^2 \end{gathered}[/tex]1.4.2 Given that Area's formula is a quadratic function, its maximum is placed at its vertex. The x-coordinate of the vertex is found as follows:

Write an equation of the line that passes through (-5,0) and is parallel to the line y=-2/3x-1
The equation of the line that passes through (-5,0) and is parallel to the line y = -2/3x - 1 is y = - 2 / 3 x - 10 / 3
How to find the equation of a line?The equation of a line can be represented in different form such as point slope form, slope intercept form, standard form and general form.
The equation of a line in slope intercept form is as follow:
y = mx + b
where
m = slopeb = y-interceptTherefore, the equation of the line passes through (-5,0) and is parallel to the line y = -2/3x - 1.
Parallel line has the same slope.
Therefore, the slope of the line is - 2 / 3.
Hence, let's find the y-intercept using (-5, 0)
0 = - 2 / 3(-5) + b
b = - 10 / 3
Therefore, the equation is y = - 2 / 3 x - 10 / 3

What can be values and units.Let's say you go to the store to buy six apples. You are informed by the shopkeeper that he is offering 10 apples for Rs 100. In this instance, the value and the units are the price of the apples.Recognizing the units and values is crucial when using the unitary technique to a problem.Always write the items that need to be computed on the right side and the things that are known on the left side to simplify things.We are aware of the quantity of apples and the amount of money in the aforesaid problem.According to our question-
inverse proportionality means L = k/l
So the equation is:
L = k(wd2/l)
You are given:
w = 6 in
d = 5 in
l = 12 ft
L = 7666 lbs
7666 = k(6*52/12)
Solve for the constant, k.
7666 = k (6*25/12)
7666 = k (150/12)
7666 = k (12.5)
613.28 lbs/(ft.in3) = k
Use this k-value to solve for L in the last part of the question.
What safe load, L would a beam 3 in. wide, 7 in. deep and 15 ft long of the same material support? (Round off your answer to the nearest pound.)

iceberg is 15 meters below sea level.
What is the total height and depth of
the iceberg.
The total height of the iceberg is 38 meters and the total depth of the iceberg is 15 meters.
What is meant by height and depth?Height is a mathematical term that refers to the vertical distance between an object's top and base. Sometimes, it has the designation altitude. The measurement of an item along the y-axis in coordinate geometry is referred to as height in geometry.
The depth of an object is the separation between its closest and farthest ends. Jane, for instance, measures a box. Jane estimates the depth of the box by calculating the distance between the end of the box that is closest to her and the end that is farthest away.
Given, the height of an iceberg above the water is 23 meters.
And also given that the bottom of the iceberg is 15 meters below sea level.
Total height = above the water + below the water
Total height=23+15=38 meters
Depth= total height - iceberg above the water
Depth=38-23=15 meters
The total height of the iceberg is 38 meters.
The total depth of the iceberg is 15 meters.

0.115 lbs/day is the rate of change of baby's weight.
What is rate of change ?When anything changes over time, it does so at a certain rate, or ROC. Therefore, rather than the size of each change individually, it is the pace of change—or, more specifically, its acceleration or deceleration. Rate of change in the financial world is utilized to comprehend price returns and spot trend momentum.

The correct equation that represents the slope equation using the given information will be (B) y = -5x + 2.
What exactly are slopes?The slope of a line can be used to gauge how steep it is.Divide the change in y by the change in x, or "rise over run," to find the slope in mathematics.Locate two locations along the chosen line and find their coordinates.Find the y-coordinate difference between these two places (rise).Find the difference between the x-coordinates of these two points (run).Subtract the difference in y-coordinates from the difference in x-coordinates (rise/run or slope).So, the slope equation will be:
Slope form: y = MX + bM is -5 and points are (-1, 2).Now, the correct question will be:

What is the slope of the line that passes through the points (0, -6) and (0, -5)?
Write your answer in simplest form.
Answer:
0
Step-by-step explanation:
Slope = change in y/change in x
Start with y: Our y2 term is -5, and y1 is -6
Set up the equation:
y2-y1
Plug in our values:
-6 - (-5) = -6 + 5 == -1
Now x:
x2 is 0, and x1 is 0
Set up the equation:
x2-x1
Plug in our values:
0-0 = 0
Now, put those two values together and you have the slope!
-1/0 is the slope
We can simplify this further though.
Anything divided by 0 is 0, so the slope = 0

The distributive property states that multiplying the sum of two or more variable by a number gives the same result as when each variable is multiplied individually by the number and the products are added together.
The distributive property of subtraction is
A(B-C) = AB - AC
Apply the distributive property
(x / m^2 - 2x / m)(3x^2y / m)
= (x / m^2)(3x^2y / m) - (2x / m)(3x^2y / m)
Multiply the terms
= (3x^3y / m^3) - (6x^3y / m^2)

Agnes pays state income tax equal to 3.75% of her federal taxable income. She pays federal income tax equal to 28.4% of her federal taxable income. This year she paid $15,449.60 in federal income tax. How much did Agnes pay in state income tax?
The amount that Agnes paid in state income tax is; SI = $2,040
How to calculate state income tax?To find the state income tax in this situation, we would use this equation:
t = px
Where;
t = Total paid
p = percentage
x = federal income tax
In this case, we would need to find what x is.
We are given;
Total paid = $15,449.60
Percentage of federal tax = 28.4% = 0.284
The equation is;
15,449.60 = 0.284x
dividing both sides by 0.284 gives;
x = $54,400.
Now, we can calculate Agnes' state income tax from the formula:
SI = x × p
SI = 54400 × 0.0375
SI = $2,040
