A trapezoid is also as a trapezium, is a flat closed shape having 4 straight  

sides, with one pair of parallel sides . a trapezium can also a  parallel legs .

Point O (the point of intersection of diagonals )divides two diagonals AC and BD into parts that are proportional:

AO/CO = DO/BO

Then AO x BO = CO xDO

Consider triangle ABO. The area of this triangle is

Aabo  = 1/2 x AO x BO x sin ∠AOB

Consider triangle COD. The area of this triangle is

Acod = 1/2 x CO x DO x sin ∠COD

Since  AO x  BO = CO x DO and angles AOB and COD are congruent as vertical angles

Acod = 1/2 x BO x AO x sin ∠ AOB = Aaob = 6. inc.sq.

The perimeter of each pool is 92 ft.

What is perimeter?

A perimeter is a closed route that covers, surrounds, or outlines a two-dimensional form or length. The circumference of a circle or an ellipse is its perimeter.

Given, the triangles are congruent so,

20x-15 = 15x+15

=> 20x-15x = 15+15

=> 5x = 30

=> x = 30/5 = 6

Therefore, perimeter = (4x-4) + (5x+1) + 41

                                    = (4x6 - 4) + (5x6 + 1) + 41

                                    = 20 + 31 + 41

                                    = 92

Neither graph in this problem represents a proportional relationship, as they have different rates of change. Examples are as follows:

1. Different rates between days 0-10 and 30-40.

2. Different rates between hours 0 - 1 and 2 - 3.

A direct proportional relationship is a function in which the output variable is given by the multiplication of the input variable and the constant of proportionality k, as the rule below shows.

y = kx

Hence, a function will only be proportional if the rate of change is constant for all intervals.

For item 1, we have that:

Hence it is not a proportional relationship, due to the different rates.

For item 2, we have that:

For the same reason as item 1, of the different rates, it does not represent a proportional relationship.

Answer:

[tex]\dfrac{\dfrac{3}{5}x + \dfrac{7}{10}y}{x + y}[/tex]  

where x = number of students in Zankers class and y = number of students in Haynes' class

If the number of students in these classes are equal then the average fraction is 13/20

Step-by-step explanation:

Let x = number of students in Zanker's class

Then number of students who went for the trip is [tex]\dfrac{3}{5}x[/tex]

Let y  be the number of students in Haynes' clas

Number of students who went = [tex]\dfrac{7}{10}y[/tex]

Total number of students who went on the trip = [tex]\dfrac{3}{5}x + \dfrac{7}{10}y[/tex]

Total number of students in both classes = x + y

So average fraction

=
= [tex]\dfrac{\textsf {Total Number of Students On Trip}}{\textsf {Total Number of Students}}\\\\= \dfrac{\dfrac{3}{5}x + \dfrac{7}{10}y}{x + y}[/tex]

Without knowing how many students are in each class we can only come up with an equation

If we assume the same number of students in each class
Then we get total students who went on trip =  [tex]\dfrac{3}{5} N + \dfrac{7}{10}N[/tex][tex]= \left( \dfrac{3}{5} + \dfrac{7}{10}\right)N= \left(\dfrac{13}{10}\right)N[/tex]

x = 118 text messages

Step-by-step explanation:

Since the total cost of $59.50 is comprised of the flat fee of $30 plus $0.25 for each text message, we can write

$59.50 = $30 + $0.25x

$29.50 = $0.25x

x = 118 text messages

The expansion and simplified form of the expression [(x+3)(2x-1)(x+4)] will be (2x³ + x² - 25x - 12).

As per the question statement, we are provided with the expression of [(x+3)(2x-1)(x+4)] where three separate factors of the variable "x" are multiplied with each other.

We are required to expand and simplify the above-mentioned expression to obtain our desired answer.

Given, [(x + 3)(2x - 1)(x + 4)]

= [{(x + 3)*(2x - 1)}(x + 4)]

= [{(x*2x) - (x*1) + (3*2x) - (3*1)}(x + 4)]

= [(2x² - x - 6x -3)(x + 4)]

= [(2x² - 7x -3)(x + 4)]

= [(2x²*x) + (2x²*4) - (7x*x) - (7x*4) - (3*x) - (3*4)]

= [2x³ + 8x² - 7x² - 28x - 3x - 12]

= [2x³ + (8x² - 7x²) - (28x + 3x) - 12]

= (2x³ + x² - 25x - 12)

The coordinates of Z are (-11.5, 5)

When a point on a line segment divides it into two segments, the formula used to determine the coordinates of that point is known as the section formula. Let us say, we have a point P(x,y) that divides the line segment with marked points as A (x1,y1) and B(x2,y2). To find the coordinates, we use the section formula, which is mathematically expressed as:

P(x, y) =  (m[tex]x_2[/tex] + n [tex]x_1[/tex] / m+ n, m [tex]y_2[/tex] +n[tex]y_1[/tex] /m+ n)

Given coordinates:

XY:XZ is 2:3

X is located at (6,10) and Y is located at (-1,8).

let the coordinates of Z(x, y)

using section formula

-1 = (2x + 18)/ 5

-5 = 2x +18

2x = -23

x= -11.5

What is equation of line in slope intercept form?

The most general form of equation of line in slope intercept form is given by y = mx + c

Where m is the slope of the line and c is the y intercept of the line.

Slope of a line is the tangent of the angle that the line makes with the positive direction of x axis.

If [tex]\theta[/tex] is the angle that the line makes with the positive direction of x axis, then slope (m) is given by

m = [tex]tan\theta[/tex]

The distance from the origin to the point where the line cuts the x axis is the x intercept of the line.

The distance from the origin to the point where the line cuts the y axis is the y intercept of the line.

The integer solutions of the system of inequalities are x >= 1 and b <= 0

Inequality expressions are mathematical statements that are represented by variables, coefficients and operators where the opposite sides are not equal

System of inequalities 1

Here, we have

3 - 18x < 0

0.2 - 0.1x > 0

Rewrite as

0 < 0.2 - 0.1x

The above means that

3 - 18x  < 0.2 - 0.1x

Collect the like terms

So, we have

3 - 0.2 < 18x + 0.1x

Evaluate the like terms

So, we have

2.8 < 18.1x

Divide both sides by 18.1

So, we have

0.155 < x

Rewrite as

x > 0.155

The integer value greater than 0.155 is at least one

Hence, the integer solution of the system is x >= 1

System of inequalities 2

Here, we have

6 - 4b > 0

3b - 1 > 0

The above means that

6 - 4b > 0 < 3b - 1

Collect the like terms

So, we have

-4b > - 6 + 0 + 1< 3b

Evaluate the like terms

So, we have

-4b > -5 < 3b

Solve for b

b < -1.25 or -1.67 < b

The value of a is 20.

When two straight lines or rays intersect at a single endpoint, an angle is created. The vertex of an angle is the location where two points come together. The Latin word "angulus," which means "corner," is where the term "angle" originates.

Given that,

HL is perpendicular to HJ

m ∠2 = (a + 15)°

and

m ∠3 = (a + 35)°

If HL and HJ are perpendicular,

Then,

m ∠2 + m ∠3 = 90°

(a + 15)°  +  (a + 35)° = 90°

Now, solve for a

(a + 15)°  +  (a + 35)° = 90°

a + 15 + a + 35 = 90

a + a = 90 - 15 - 35

2a = 40

The transformations that maps polygon jklm to polygon nopq are described as follows:

C. Reflection across the y-axis, translation 2 units left and 6 units up, dilation with center (0,0) and scale factor 1/2.

The first transformation was a reflection, changing the orientation of the polygon.

Due to the orientation assumed with the equivalent vertices, NL, KO, PJ and MQ, the reflection was over the y-axis, with vertex O assuming coordinates (2,-2).

Since vertex O is at the y-axis, the polygon was translated 2 units left and 6 units up, with O assuming coordinates (0, 4).

The final coordinates of O are (0,2), hence the polygon was dilated with a scale factor of 1/2, as 4 x 1/2 = 2, which is the final y-coordinate of O.

The problem is incomplete, and the complete problem is given by the image at the end of the answer.
