What is CD? to number 11
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:
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.

Which of the following accurately completes the missing statement and justification of the two-column proof?
m∠BEC + m∠CED = m∠BED; Definition of a Linear Pair
m∠ABC + m∠BEC = m∠BED; Angle Addition Postulate
m∠ABC + m∠BEC = m∠BED; Definition of a Linear Pair
m∠BEC + m∠CED = m∠BED; Angle Addition Postulate
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:
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:
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.

Num grupo 1 ponto
de 400 pessoas, 30% são
homens e 65% das mulheres
são estrangeiras. Quantas
mulheres desse grupo de
pessoas não são estrangeiras?
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

Find the area of the circle. Use 3.14 for pi.
Circle diameter of 12 inches.
A: 113.04in^2
B. 452.16in^2
C. 37.68in^2
D. 354.95in^2
Please, show your work if you have a answer to this question.
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

What's the value of u+ v
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
