Find the area of quadrilateral ABCD. [Hint: the diagonal divides the quadrilateral into two triangles.]

Answer: B ,hope it helps!

Answer:

A = pi(r)^2

A = pi(40)^2

A = 1,600pi sq. ft.

Therfore the answer is C.) 1,600 pi sq. ft.

I hope this helps you!!

Answer:

C - 1600\(\pi\) sq. ft.

Step-by-step explanation:

Since the answer has to be in terms of pi, we can exclude that from the equation.

The formula to find the area of a circle is \(\pi r^2\) where r is the radius. If we plug in 40 for r, we get 1600\(\pi\).

Negative 3, negative 2.4, negative 1.5, negative 2 and one-fourth, negative 1 and one-eighth

Answer:

\(x=20^o\)

Step-by-step explanation:

from the diagram, we can define the remaining angle in the quadrilateral through the sum of angles in any quadrilateral, which is \(360^o\), so the remaining unknown angle should be:

\(360-(50+2x+x)=310-3x\)

now that we have the unknown angle, we can find x through the point at which the outer angle is. \(x+90\) degrees. (sum of angles at one point is 360 degrees)

\(310-3x +x+90=360\\\\400-2x=360\\2x=400-360\\x=20^o\)

The value of variable x is,

x = 20

We have to given that,

In the diagram below, all angles are given in degrees.

Since, the sum of angles in any quadrilateral is, 360 degree.

Let measure of fourth angle is, y

Hence, We get;

(50 + 2x + y + x ) = 360

50 + 3x + y = 360

3x + y  = 360 - 50

3x + y = 310

y = 310 - 3x

Now, We get;

(310 - 3x) + (x + 90) = 360

Solve for x,

310 - 3x + x + 90 = 360

400 - 2x = 360

400 - 360 = 2x

2x = 40

x = 40/2

x = 20

Therefore, The solution is, 20

Answer:

1. Slope = -3.000/2.000 = -1.500

2.  x-intercept = 0/3 = 0.00000

3. y-intercept = 0/2 = 0.00000

Step-by-step explanation:

Rearrange:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

Equation of a Straight Line

1.1     Solve   2y+3x  = 0

Tiger recognizes that we have here an equation of a straight line. Such an equation is usually written y=mx+b ("y=mx+c" in the UK).

"y=mx+b" is the formula of a straight line drawn on Cartesian coordinate system in which "y" is the vertical axis and "x" the horizontal axis.

In this formula :

y tells us how far up the line goes

x tells us how far along

m is the Slope or Gradient i.e. how steep the line is

b is the Y-intercept i.e. where the line crosses the Y axis

The X and Y intercepts and the Slope are called the line properties. We shall now graph the line  2y+3x  = 0 and calculate its properties

Graph of a Straight Line :

Calculate the Y-Intercept :

Notice that when x = 0 the value of y is 0/2 so this line "cuts" the y axis at y= 0.00000

 y-intercept = 0/2  =  0.00000  

Calculate the X-Intercept :

When y = 0 the value of x is 0/3 Our line therefore "cuts" the x axis at x= 0.00000

 x-intercept = 0/3  =  0.00000  

Calculate the Slope :

Slope is defined as the change in y divided by the change in x. We note that for x=0, the value of y is -0.000 and for x=2.000, the value of y is -3.000. So, for a change of 2.000 in x (The change in x is sometimes referred to as "RUN") we get a change of -3.000 - -0.000 = -3.000 in y. (The change in y is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)

   Slope     = -3.000/2.000 = -1.500  

Geometric figure: Straight Line

 Slope = -3.000/2.000 = -1.500

 x-intercept = 0/3 = 0.00000

 y-intercept = 0/2 = 0.00000

Answer:

Using the order of operations (PEMDAS), we evaluate the expression as follows:

First, we perform the operations inside the parentheses: 8 + 4 = 12.

Next, we multiply 5 by 12: 5(12) = 60.

Then, we combine the like terms: -3 - 60 + 16 - 32 = -79.

Therefore, -3 - 5 (8 + 4) + 16 - 32 = -79.

The perimeter of the trapezoid is given by the equation Q = 186

The Trapezoid is a 4 sided polygon. Two sides of the shape are parallel to each other and they are termed as the bases of the trapezoid. The non-parallel sides are known as the legs or lateral sides of a trapezoid.

There are three types of trapezoids , and those are given below:

a) Isosceles Trapezoid

b) Scalene Trapezoid

c) Right Trapezoid

The area of the Trapezoid is given by

Area of Trapezoid = ( ( a + b ) h ) / 2

where , a = shorter base of trapezium

b = longer base of trapezium

h = height of trapezium

Given data ,

Let the perimeter of the scaled trapezoid be Q

Quadrilateral Q is a scaled copy of Quadrilateral P created with a scale factor of 3

Now , the trapezoid Q = 3 x trapezoid P

The perimeter of trapezoid Q = 3 x perimeter of trapezoid P

Length of longer base of P = 25

Length of shorter base of P = 7

And , the perimeter of trapezoid P = length of longer bases + length of bases + height

Substituting the values in the equation , we get

Perimeter of P = 15 + 15 + 7 + 25

On simplifying the equation , we get

Perimeter of P = 62

Now , perimeter of trapezoid Q = 3 x Perimeter of P

So , perimeter of trapezoid Q = 3 x 62

Perimeter of trapezoid Q = 186

Therefore , the value of Q is 186

Hence , the perimeter of trapezoid Q is 186

Answer:

p = 12.20h

30.5 hours

Step-by-step explanation:

Jackson works as a veterinary technician and earns per hour = $12.2

He works in a normal week = 40 hours

Let hours = h and weekly pay = p

p = 12.20h

p = $12.20 × 40

= $488.00

Last week Jackson was ill and missed some work.

 His total pay before deduction was $372.10

To find the hours he work the equation will be p = 12.20h

372.10 = 12.20h

372.10/12.20 = h

h= 30.5

Answer:

A function is a mathematical relation in which each input (domain value) is associated with exactly one output (range value). In other words, for a relation to be a function, each input can have only one corresponding output. Let's analyze the given pairings:

(a person’s age in years, that same person’s height in inches) - This can be a function because one person's age in years should correspond to a single height in inches.

(a person’s weight in pounds, that same person’s height in inches) - This can also be a function because one person's weight in pounds should correspond to a single height in inches.

(a person’s height in centimeters, that same person’s height in inches) - This can be a function because one person's height in centimeters should correspond to a single height in inches.

(a person’s telephone number, that same person’s height in inches) - This may not necessarily be a function. It's possible for two different people to have the same height in inches but different telephone numbers.

So, the pairings that always describe a function are:

(a person’s age in years, that same person’s height in inches)

(a person’s weight in pounds, that same person’s height in inches)

(a person’s height in centimeters, that same person’s height in inches)

These three pairings meet the criteria of a function, where each input corresponds to a unique output.

The pairing that always describes a function is option C. (a person’s height in centimeters, that same person’s height in inches)

A pairing describes a function when each unique input (domain element) is associated with exactly one unique output (range element). In other words, there should be no ambiguity or multiple outputs for a single input. Let's analyze the given pairings:

1. (a person’s age in years, that same person’s height in inches): This pairing may not always describe a function because multiple people can have the same age, but they might have different heights. So, there can be multiple outputs for the same input (age).

2. (a person’s weight in pounds, that same person’s height in inches): Similar to the first pairing, this may not always describe a function because different people can have the same weight but different heights.

3. (a person’s height in centimeters, that same person’s height in inches): This pairing describes a function because for each unique height in centimeters, there is only one corresponding height in inches.

4. (a person’s telephone number, that same person’s height in inches): This pairing may not always describe a function because multiple people can have the same telephone number, but they might have different heights. So, there can be multiple outputs for the same input (telephone number).

So, the pairing that always describes a function is: (a person’s height in centimeters, that same person’s height in inches)
