Step-by-step explanation:

You want the area and perimeter of a rectangle that is 54 inches in length and 30.4 inches in width.

The area formula is ...

  A = bh

We can use the length as the "base" and the width as the "height", so we have ...

  A = (54 in)(30.4 in) = 1641.6 in²

The area of the television screen is 1641.6 square inches.

The perimeter of a rectangle is given by the formula ...

  P = 2(L +W)

Using the given length and width, the perimeter is found to be ...

  P = 2(54 in + 30.4 in) = 2(84.4 in) = 168.8 in

The perimeter of the television screen is 168.8 inches.

The area of the rectangular television screen is 1641.6 square inches and the perimeter of the television screen is 84.4 inches.

What is the area of a rectangle?
The area a rectangle occupies is the space it takes up inside the limitations of its four sides. The dimensions of a rectangle determine its area. In essence, the area of a rectangle is equal to the product of its length and breadth. Its area is the space that the rectangle's boundary encloses.
Mathematically, area of a rectangle = length * width = l * w
What is the perimeter of a rectangle?
The perimeter is defined as the sum of all sides of the rectangle. Mathematically, perimeter of a rectangle = 2(length + width) = 2*(l + w)

Given, the length of the television screen = l = 54 inches
The width of the television screen = w = 30.4 inches
Using the formula mentioned in the literature above,
Area of the television screen = l * w = 54*30.4 = 1641.6 square inches
Also, perimeter of the television screen = l + w = 54 + 30.4 = 84.4 inches
Thus, the area of the rectangular television screen is 1641.6 square inches and the perimeter of the television screen is 84.4 inches.

Step-by-step explanation:

sadly we don't know anything about the size of the mirror on the ground, or if e.g. the 1.65 m from the mirror mean from the edge of the mirror or from the x at the center of the mirror.

so, we must assume the mirror as a dot without any significant lengths in the calculation.

we have 2 right-angled triangles.

1. the small one : from Yusuf's eyes to the ground at his feet to the x on the mirror on the ground.

2. the large one : from the top of the building to the bottom of the building on the ground to the x on the mirror on the ground.

the mirroring creates a dilation from the large triangle to the small triangle through the point x on the mirror.

in other words, all the angles stay the same, and there is one constant scale factor for all the lengths of one triangle to the other, making both triangles similar.

that means that the scale factor "f" of the ground distances from the small to the large triangle is

10.25 / 1.65 = 1025 / 165 = 6 35/165 = 6 7/33 =

= 6.212121212...

the scaling from Yusuf's height (well, his eye level) to the height of the school must follow the same ratio :

school height / Yusuf's eye level =

= h/1.55 = 10.25/1.65

h = 10.25 × 1.55 / 1.65 = 1025 × 155 / 16500 =

= 9.628787879... m ≈ 9.63 m

the school is approximately 9.63 m tall.

FYI : this is the same principle as with a camera. the lens (and the mirror inside if applicable) create a dilated "projection" onto a film or an array of digital light sensors, so that the captured image retains all the angles and all the length ratios of the original.

but to know from the picture e.g. how tall the original was, we need to know also the distance from which the picture was taken. otherwise this can't be answered.

Step-by-step explanation:

slope intercept form is: y = ax + b

so, 19x - 19y = 18

By using the table of values, we have the following:

A function can be defined as a mathematical expression which is used to define and represent the relationship that exists between two or more variables. This ultimately implies that, a function is typically used for mapping an input variable (x-value) to an output variable (y-value or f(x)).

In this exercise, you're required to determine the value of each function based on the value of x shown in the table above. Therefore, you would identify the input variable (x-value) that corresponds to the value of the output variable (y-value or f(x)) in the given table and vice-versa.

Answer:

D

Step-by-step explanation:

Look at the original figure that is complete.  The left side of the figure has a length of 3 units, the top of the figure has a length of 2 units and the bottom of the figure has a length of 3 units.  

If you multiply each of those lengths, you will have  9 (3x3), 6 (2x3) and 9 (3x3).  Do you see in the large figure to the right, that you have a left side of 9, a top of 6 and a bottom of 9?  That is what you original figure looks like if we multiply the sides by 3.  We are missing the right side point.  That is the point on the right side that points inward.

If you look at the original shape and start at the left had bottom corner, you would have to move up one and one to the right to plot the point to finish the figure.  So, for the new figure we would need to go up three and three to the right to put the last point.  That would be point D.

Step-by-step explanation:

We can solve with functions exactly as we do algebraic equations. Our goal is to isolate the variable.

We're given:

[tex]q(x) = \dfrac{1}{2}x-3\\\\q(x) = -4[/tex]

Solve using substitution:

[tex]\dfrac{1}{2}x-3=-4[/tex]

Isolate x:

[tex]\dfrac{1}{2}x=-4+3\\\\\dfrac{1}{2}x=-1\\\\x=-2[/tex]

x = -2

The value of the variable x is 2 and length of the segment AB = 25 and length of segment BC is 14.

If a Line segment AC is given in a plane and B is some point between the points A and C on the line segment AC. Then two segments of the line segment ac are formed that are AB and BC. and length of AC is equal to the sum of lengths of AB and BC.

Then AC = AB +BC

Given that  B is point on the line segment AC

Length of AB line = 9x+7

Length of BC = -3x +20

Length of AC = 39

Using segment addition postulate,

we have AC = AB +BC

⇒ 39 = 9x+7 + (-3x) +20

⇒ 39 = 9x -3x +7+20

⇒39 = 6x +27

⇒ 39-27 = 6x

⇒ 12 = 6x

⇒ 2 = x

∴ Length of AB will be = 9(2) +7 = 25

∴ Length of BC will be = -3x + 20 = -3(2) +20 = 14

Find the value of s on one side of the equation to isolate it.

1.1=s+2.3/3

First, switch sides.

[tex]\sf{\dfrac{s+2.3}{3}=1.1}[/tex]

Multiply by 3 from both sides.

[tex]\sf{\dfrac{3\left(s+2.3\right)}{3}=1.1* \:3}[/tex]

Solve.

1.1*3=3.3

s+2.3=3.3

Then, subtract by 2.3 from both sides.

s+2.3-2.3=3.3-2.3

Solve.

Subtract.

3.3-2.3=1.0=1

s=1

The division of (4+5i) / (2-4i) is performed by multiplying the numerator and denominator by 2+4i and the result of the given expression is (-3/5) + (13/10) i

The given expression is

(4+5i) / (2-4i)

Here we have to divide the given complex number

First multiply both numerator and denominator by 2+4i

(4+5i) / (2-4i) × (2+4i) / (2+4i)

= [tex]\frac{(4+5i)(2+4i)}{(2-4i)(2+4i)}[/tex]

Multiply the terms in the numerator and denominator.

ASA = angle side angle

It refers to knowing two pairs of congruent angles, and a pair of congruent sides between the angles.

The angle markers tell us which angles are congruent. The shared overlapped sides are congruent (since any segment is congruent to itself; aka reflexive property).

ASA is slightly different from AAS in that the congruent sides for AAS are not between the congruent angles.

Question b :

Largest possible value of 100 draws = 100 * (Highest of the ticket values)

                                                             = 100 * 6

Answer: Look at step by step

Step-by-step explanation:

(ax + b)(ax + b) = [tex]a^{2}[/tex] [tex]x^{2}[/tex]+ 2abx + [tex]b^{2}[/tex]

Substitute g into x

[tex]a^{2}[/tex] = 7

a = [tex]\sqrt{7}[/tex]

2ab = -3

b = -3 / (2 x [tex]\sqrt{7}[/tex])

[tex]b^{2}[/tex] = 9 / (4 x 7) = 9/28

So the term to be added to make a perfect square is 9/28
