VWXY is a parallelogram. Find the measure of XY and WY 8

Answers

Answer 1

Remember that

in a parallelogram, the diagonals bisect each other

that means

VZ=ZX

substitute given values

n+7=3n

solve for n

3n-n=7

2n=7

n=3.5

therefore

VX=(n+7)+3n ----> by addition segments postulate

VX=4n+7

substitute the value of n

VX=4(3.5)+7

VX=21

What is the slope of the line that passes through the points (0, -6) and (0, -5)?
Write your answer in simplest form.

Answers

Answer:

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

Isabella's baby weighed 8.5 lbs
when it was first born. 20 days
later, it weighed 10.8 lbs. what is the rate of change of the baby's weight per day?

Answers

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.

Calculation

rate of change in baby's weight will be = (10.8 - 8.5)/ 20

= 2.3 / 20

= 0.115 lbs/day

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

Answers

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.

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?

Answers

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

The result of the expression (x / m^2 - 2x / m)(3x^2y / m) is (3x^3y / m^3) - (6x^3y / m^2)

The given expression is

(x / m^2 - 2x / m)(3x^2y / m)

Here we have to apply distributive property

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)

Hence, the result of the expression (x / m^2 - 2x / m)(3x^2y / m) is (3x^3y / m^3) - (6x^3y / m^2)

Write an equation of the line that passes through (-5,0) and is parallel to the line y=-2/3x-1

Answers

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-intercept

Therefore, 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

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:

[tex]x_V=\frac{-b}{2a}[/tex]

where a is the leading coefficient and b is the x-coefficient of the function. In this case, the coefficients are a = -4 and b = 280, then:

[tex]\begin{gathered} x_V=\frac{-280}{2(-4)} \\ x_V=\frac{-280}{-8} \\ x_V=35 \end{gathered}[/tex]

Evaluating the Area at x = 35, the maximum Area is:

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

Answers

The solution to the system of equations is x = 12

Equal number of men and women have received bachelor's degrees up till 1982Women have a higher rate of receiving bachelor's degrees each year than men

The solution to the system of equations

The system of equations is given as

y = 3.6x + 444

y = 14.2x + 315

Substitute y = 14.2x + 315 in y = 3.6x + 444

14.2x + 315 = 3.6x + 444

Evaluate the like terms

10.6x = 129

Divide both sides by 10.6

x = 12

Interpret the result in (a)

In (a), we have

x = 12

Where

x is the number of years after 1970.

This means that

Year = 1970 + 12

Evaluate

Year = 1982

So, it means that the total number of men and women that have received bachelor's degrees up till 1982 are equal

On the graph, we can interpret the trends to be:
