What is the perimeter of this title ? HURRY PLEASE !!

Answer:

Yes; LA (D)

Step-by-step explanation:

one of the legs are congruent.  LA and PT are congruent.  This makes up the "L" part of "LA"

Also, angle PCT and angle LFA are congruent base on the diagram.  This makes up the "A" part of "LA"

Option (D) points (7,2) (1,2) are separated by distance of 6 units.

It is the length of the straight line connecting these points in the coordinate plane. This distance can never be negative, therefore we take the absolute value while finding the distance between two given points. The distance formula is an application of the Pythagorean theorem.

For the given situation,

The distance between the two points must be 6 units.

Let the points be (x1,y1) and (x2,y2)

The distance formula is

[tex]d=\sqrt{(x_2-x_1)^{2} +(y_2-y_1)^{2} }[/tex]

We need to check all the options.

Option A: (x1,y1) = (5,6), (x2,y2) = (4,6)

⇒ [tex]d=\sqrt{(4-5)^{2} +(6-6)^{2} }[/tex]

⇒ [tex]d=\sqrt{(-1)^{2} +(0)^{2} }[/tex]

⇒ [tex]d=\sqrt{1}[/tex]

⇒ [tex]d=1[/tex]

Distance ≠ 6. So option A is incorrect.

Option B: (x1,y1) = (1,3), (x2,y2) = (6,3)

⇒ [tex]d=\sqrt{(6-1)^{2} +(3-3)^{2} }[/tex]

⇒ [tex]d=\sqrt{(5)^{2} +(0)^{2} }[/tex]

⇒ [tex]d=\sqrt{25}[/tex]

⇒ [tex]d=5[/tex]

Distance ≠ 6. So option B is incorrect.

Option C: (x1,y1) = (8,1) , (x2,y2) = (1,1)

⇒ [tex]d=\sqrt{(1-8)^{2} +(1-1)^{2} }[/tex]

⇒ [tex]d=\sqrt{(-7)^{2} +(0)^{2} }[/tex]

⇒ [tex]d=\sqrt{49}[/tex]

⇒ [tex]d=7[/tex]

Distance ≠ 6. So option C is incorrect.

Option D: (x1,y1) = (7,2) , (x2,y2) = (1,2)

⇒ [tex]d=\sqrt{(1-7)^{2} +(2-2)^{2} }[/tex]

⇒ [tex]d=\sqrt{(-6)^{2} +(0)^{2} }[/tex]

⇒ [tex]d=\sqrt{36}[/tex]

⇒ [tex]d=6[/tex]

Distance = 6. So option D is correct.

Hence we can conclude that option (D) points (7,2) (1,2) are separated by distance of 6 units.

Answer:

The third quartile is 56.45

Step-by-step explanation:

The given parameters are;

The first quartile, Q₁ = 30.8

The median or second quartile, Q₂ = 48.5

The mean, [tex]\bar x[/tex] = 42.0

Coefficient of skewness = -0.38

The Bowley's coefficient of skewness (SK) is given as follows;

[tex]SK = \dfrac{Q_3 + Q_1 - 2 \times Q_2}{Q_3 - Q_1}[/tex]

Plugging in the values, we have;

[tex]-0.38 = \dfrac{Q_3 + 30.8 - 2 \times 48.5}{Q_3 - 30.8}[/tex]

Which gives;

-0.38×(Q₃ - 30.8) = Q₃ + 30.8 - 2 × 48.5

11.704 - 0.38·Q₃ = Q₃ - 66.2

1.38·Q₃ = 11.704 + 66.2 =  77.904

Q₃ = 56.45

The third quartile = 56.45.

Answer:

The correct answer is "[tex]64*x^2 - 16[/tex]".

Step-by-step explanation:

The product [tex](8*x - 4)*(8*x + 4)[/tex] is a notable product, which happens when we have the product of the sum of two values with the subtraction of these same two values. In cases like this the answer will always be the first term squared minus the second term squared, therefore we have:

[tex](8*x - 4)*(8*x + 4) = 64*x^2 - 16[/tex]

The correct answer is "[tex]64*x^2 - 16[/tex]".

Answer:

15.5^2 + 14.0^ = 20.8^2

436.25 = 432.64

it is not a triangle because a+b is not = c

Answer: These given lengths do not make up a right triangle.

Step-by-step explanation:

In order to figure out if this is a right triangle or not, we would need to use the Pythagorean Theorem in order to verify if these lengths satisfy the properties of a right triangle. We would need to use the formula a^2 + b^2 = c^2.

14^2 + 15.5^2 = 20.8^2

196 + 240.25 = 432.64

436.25 ≠ 432.64

Therefore, this is not a right triangle.

Answer:

c= 1

Step-by-step explanation:

To get rid of (c) on the right side, simply divide 2^n both side. But first collect like terms on the left side so you will get 2^n + 1 which you will then simplify the like term(2^n) and you will left with c= 1.

Answer:

Step-by-step explanation:

The percentile for the z scores are gotten from the normal distribution table. The z cores are already known.

1) For the ChatLong company, the z score is 0. The area corresponding to the z score from the normal distribution table is 0.5. Therefore, the percentile is

0.5 × 100 = 50%

2) For the Talk-a-lot company, the z score is 1. The area corresponding to the z score from the normal distribution table is 0.84. Therefore, the percentile is

0.84 × 100 = 84%

The coordinate plane is missing, so i have attached it.

Answer:

Perimeter of room = 140 ft

Area of room = 1200 sq.ft

Step-by-step explanation:

From the cordinate plane attached, we can see the polygon QRST which represents the floor plan of the roo.

Thus;

The length of the sides of the room are;

ST = RQ = 30

QT = RS = 40

Perimeter of a rectangle is the sum of all sides of the rectangle.

Thus, perimeter of the room = (30 × 2) + (40 × 2) = 140 ft

Now, area of a rectangle is the product of two perpendicular sides.

Thus area of room = 40 x 30 = 1200 sq.ft

Answer:

A

Step-by-step explanation:

Given

x² - 13x + 30

Consider the factors of the constant term (+ 30) which sum to give the coefficient of the x- term (- 13)

The factors are - 3 and - 10, since

- 3 × - 10 = + 30 and - 3 - 10 = - 13 , thus

x² - 13x + 30 = (x - 3)(x - 10) ← in factored form

Thus (x - 3) is a factor of the polynomial → A

Answer:

[tex](x - 3)[/tex]

Answer A is correct

Step-by-step explanation:

[tex]{x}^{2} - 13x + 30 \\ {x}^{2} - 10x - 3x + 30 \\ x(x - 10) - 3(x - 10) \\ = (x - 3)(x - 10)

Answer:

Step-by-step explanation:

Hello,

The circumference of the cake is 25(1/7), but we don't know the area of the cake.

Assuming the cake has a shape of a circle,

Circumference of a circle = 2πr

Where r = radius of the circle.

Area of a circle = πr²

But π = 22 / 7

We have to first find the value of r.

2πr = 25(1/7)

2×(22/7)×r = 25(1/7)

(44/7)r = 176 / 7

(44 × 7)r = 176 × 7

44r = 176

r = 176 / 44

r = 4 inches

Area of the circle = πr²

A = (22 / 7) × 4²

A = 22 / 7 × 16

A = 352 / 16

A = 22 (inches)²

The area of the cake is 22in²

Answer:

c. hyperbola, (1,-1)

Step-by-step explanation:

Answer:

c

Step-by-step explanation:

With that information we can create the equation

10x + 5000 = 20x

where x is the number of earphones produced

10x is the cost to make each earphone, 5000 being the fixed costs of manufacturing, and 20x being the total revenue of selling each earphone for $20

Now to solve the equation:

subtract both sides by 10x

10x - 10x + 5000 = 20x - 10x

5000 = 10x

Now divide both sides by 10

5000/10 = 10/10 x

500 = x

Answer: D

Hope it helps :)

500 earphones must be produced to get the cost price of one ear phone of $20.

The linear equations in one variable is an equation which is expressed in the form of ax + b = 0, where a and b are two integers, and x is a variable and has only one solution.

According to the given question

The start-up costs for manufacturing earphones is $5,000.

Also, the cost to make earphones is $10.

Let x number of  earphones will produced to get a cost per unit of $20.

From the given conditions, we will get a linear equation in one variable

10x + 5000 = 20x

⇒ 5000 = 20x -10x

⇒ 5000 = 10x

⇒ x = 500

Hence, 500 earphones must be produced to get the cost of earphone of $20.

Answer:

y = (2/3)*a

Step-by-step explanation:

We can write the equation using the linear equation model:

y = ax + b

Then, to find the values of 'a' (slope) and 'b' (y-intercept), we can use two points of the graph.

Using the point (0,0), we have:

0 = a*0 + b

b = 0

Using the point (3,2), we have:

2 = a*3 + b

a = 2/3

So our equation is:

y = (2/3)*a

Let us collect like terms:

x < 0.128

Answer:

c.15 to 10

Step-by-step explanation:

The ration 12 to 8 means that for every 12 lions there are 8 tigers in the zoo.

Ratios have the quality of conservate their meaning when both values in the ratio are multiplied or divided by the same number.

For example:

a ratio of 2 to 4 is the same as a ratio of 3 to 6 (both values are multiplied by 1.5 (or in fraction by 3/2) ).

in the same way that the ratio 9 to 3 is the same as 3 to 1 (divide both values by 3).

In this case we are looking for an equivalent ratio to the 12 to 8 ratio, the answer is

c.15 to 10

because this results from multiplying the two original values by 1.25 or, in fraction, by 5/4. You can see this becase

12*1.25 = 15

and

8*1.25 = 10

we get that when we multiply the ratio 12 to 8 by 1.5 the equivalent ratio is option C.
