Answer:

The midpoint is (3, -2)

Step-by-step explanation:

[tex]m = (\frac{x1 + x2}{2}, \frac{y1 + y2}{2})\\m = (\frac{-7 + 13}{2}, \frac{2-6}{2})\\m = (\frac{6}{2}, \frac{-4}{2})\\m = (3, -2)[/tex]

Answer:

CD = 38

Step-by-step explanation:

 BC + CD = BD

8x + 8 + 6x - 28 = 10x + 24

8x + 6x + 8 - 28  = 10x + 24    {Combine like terms}

          14x - 20   = 10x + 24     { Add 20 to both sides}

                    14x   = 10x + 24 + 20

                     14x  =  10x   + 44  {Subtract 10x form both sides}

           14x - 10x   = 44

                     4x  = 44             {Divide both sides by 4}

                       x = 44/4

                       x = 11

CD = 6x - 28 = 6*11 - 28 = 66 - 28 = 38

Answer:

[tex] - 2 {b}^{3} [/tex]

Step-by-step explanation:

[tex]a^3−b^3−3ab−(a^3+b^3−3ab)[/tex]

[tex]=(a^3)+(−a^3)+(−b^3)+(−b^3)+(−3ab)+(3ab)[/tex]

[tex]= - 2 {b}^{3} [/tex]

Considering the angle theorems, the appropriate answer to the question is option D. m∠BEC + m∠CED = m∠BED; Angle Addition Postulate

In the diagram, lines BC and ED are parallel and both were intersected by a transversal AE. Thus it can be observed that:

m<ABC = BED = [tex]70^{o}[/tex] (corresponding angle theorem)

But,

m<BEC + m<CED = m<BED (angle addition postulate)

with m<CED = [tex]30^{o}[/tex], and m<BED = [tex]70^{o}[/tex]

So that,

m<BEC + [tex]30^{o}[/tex] = [tex]70^{o}[/tex]

m<BEC = [tex]70^{o}[/tex] - [tex]30^{o}[/tex]

         = [tex]40^{o}[/tex]

m<BEC = [tex]40^{o}[/tex]

Since linear pair are two angles that add up to [tex]180^{o}[/tex]. Therefore the required answer is option D.

i.e D. m∠BEC + m∠CED = m∠BED; Angle Addition Postulate

Answer:

13

Step-by-step explanation:

The common difference is 13 I

12 + 13 = 25

25 + 13 = 38

And so on.....

The answer is A because x-1 means moving left 1 on the x axis. As well, y+4 means moving 4 up on the y axis.

Answer:

Radius r = 1.

Step-by-step explanation:

Area of MNOP = (√2π)^2 = 2π.

Area 1 = Area 2, so

2π = 2πr^2

Dividing both sides by 2π:-

r^2 = 1.

r = 1.

Answer:

Oi, tudo bem?

A resposta seria: Desse grupo, 20 mulheres não seriam estrangeiras.

Step-by-step explanation:

Esse grupo é formado por 400 pessoas, ao qual:

Homens:

30% = 30/100 = 0,3

400 . 0,3 = 120

Mulheres (Estrangeiras):

65% = 65/100 = 0,65

400 . 0,65 = 260

Neste caso, temos duas formas de resolver: ou descobrir a porcentagem da quantidade de mulheres que não são estrangeiras (isto é, '100% - (35% + 60% = 5%'), depois fazer a mesma fórmula como acima, que seria:

5% = 5/100 = 0,05

400 . 0,05 =  20

Ou também, podemos somar a quantidade de pessoas que nós já sabemos (que seria: '120 + 260 = 380') e subtrair a quantidade total de pessoas com esse resultado, que é:

400 - 380 = 20

Answer:

There are only 3 differences perform

Step-by-step explanation:

I. If x is negative, y is negative then the answer is possitive

            eg. x is -2, y is -3

                  -2 × -3 = 6

II. If x is negative, y is positive then the answer is negative

            eg. x is -1, y is 2

                  -1 × 2 = -2

III. If x is possitive, y is possitive then the answer is positive

             eg. x is 2, y is 5

                    2 × 5 = 10

Alt. No matter how long x, y, z, a, b there always apply only 3 rules above. Multiply or Devide are the same rule.

Answer:

A: 113.04in^2

Step-by-step explanation:

The area of a circle is given by

A = pi r^2 where r is the radius

We know the diameter is 12 inches so the radius is 1/2 the diameter

r = 1/2 d =1/2(12) = 6inches

A = (3.14) (6)^2

A = 113.04 in ^2

Answer:

f(2) = g(2)

Step-by-step explanation:

If [tex]f(x)=2x[/tex] and [tex]g(x) = 2^x[/tex]

[tex]f(2) = 2*2 = 4\\g(2) = 2^2 = 4[/tex]

therefore, [tex]f(2) = g(2)[/tex]

The can contains 15.7 g of sugar per 100 mL. So if the can holds 330 mL of soft drink, then overall it contains

(15.7 g) / (100 mL) × (330 mL) = 51.81 g

of sugar, and this is

(51.81 g) / (90 g) ≈ 0.575667 ≈ 57.6%

so Tom's friend is correct.

Answer:

yoo dang what math class is this

Step-by-step explanation:

The hypothetical solution for the values of u + v = 3/10

The values of u and v aren't given in the question. However, giving an hypothetical solution to the problem.

Since we have an addition operator to be used on the values of u and v

Taking the values of u and v to be a real number such as :

u = 1/10 and v = 1/5

u + v = 1/10 + 1/5

Taking the L. C. M of 10 and 5;

L. C. M = 10

HENCE,

u + v = 1/10 + 1/5 = (1 + 2) / 10 = 3/10

Hence, the value of u + v = 3/10

Answer:

Answer is Triangle P'R'Q' is larger, explain how you know is steps

Step-by-step explanation:

So a Dilation is the expansion or shrinkage of an object. Because this is being dilated by 1.5 it is growing by 1.5

So triangle PRQ is the smaller version of P'R'Q' because

Line PR  = 3.1

Line RQ = 3.9

Line QP = 5

Multiplying these by 1.5 you get

Line P'R' = 4.65

Line R'Q'= 5.85

Line Q'P' = 7.5

Answer:
