What else would need to be congruent to show that ABC= DEF by the
AAS theorem?
Answer:
D
Step-by-step explanation:
It cannot be A or B because you already have both of your angles, and it cannot be C because the sides do not line up. By the process of elimination it will be D.
Answer:
D
Step-by-step explanation:
AAS = angle angle side
we already have the 2 angles so it cant be A or B. we need to find the equal corresponding side lengths. C is incorrect because side BC is not corresponding to side DF. therefore, it is D. sorry im bad at explaining but i hope this helped :)
explain how using fraction strips with like denominators makes it possible to add fractions with unlike denominators.
Fraction strips uses (least) common denominators, thus splitting big fraction into sum with like denominators and thus making addition possible.
Fraction strips require three major steps.
1. Firstly convert the problem with modelling as fraction strips.
2. Find the common denominator which should be least of all.
3. Now calculate the sum on new converted fractions.
For example:
[tex]\begin{aligned}\dfrac{1}{2} + \dfrac{3}{4} &= \dfrac{1}{4} + \dfrac{1}{4} + \dfrac{3}{4}\\&= \dfrac{2}{4} + \dfrac{3}{4}\\&= \dfrac{5}{4} = \: Ans.\end{aligned}[/tex]

Step 1: Subtract 7x from both sides.
Step 2: Subtract 18 from both sides.
Step 3: Divide both sides by -2.
therefore x=11
Answer:

The perimeter of a child's rectangular sandbox is 18 feet. Part A:if the length of the sandbox is one foot longer than the width, write an equation that can find the length and width of the sandbox. Part B:using your equation from part a, find the dimensions of the Childs sandbox. Show your work
Answer:
Length = 5 feet
Width = 4 feet
Step-by-step explanation:
Perimeter of the sandbox = 18 feet
Perimeter of a rectangle = 2(length + width)
the length of the sandbox is one foot longer than the width
Let
Width = x
length = x + 1
Perimeter of a rectangle = 2(length + width)
18 = 2{(x+1) + x}
18 = 2{x + 1 + x)
18 = 2(2x + 1)
18 = 4x + 2
4x = 18 - 2
4x = 16
Divide both sides by 4
x = 16/4
= 4
Width = x = 4 feet
length = x + 1
= 4 + 1
= 5 feet
1-6. Indicate whether each table or graph represents a proportional
relationship or a non-proportional relationship.
pls answer! nobody answer right and I am sick of failing this is for a mastery
Answer:
Step-by-step explanation:
Proportional relationship means,
x ∝ y
x = ky
[tex]\frac{x}{y}=k[/tex] where 'k' is the proportionality constant.
From table (1),
[tex]\frac{1}{5}=\frac{2}{9}\neq \text{Constant}[/tex]
Therefore, relationship is not proportional.
From table (2),
[tex]\frac{1}{6}=\frac{3}{18}=\text{constant}[/tex]
True.
So the relationship will be proportional.
From table (3),
[tex]\frac{\text{hours}}{\text{Miles}}= \frac{2}{110}=\frac{5}{175}=\frac{1}{55}[/tex]
Which is constant.
Therefore, relationship will be proportional.
From table (4),
[tex]\frac{\text{Hours}}{\text{Paid}}=\frac{3}{29.25}=\frac{5}{48.75}=0.103[/tex]
Which is constant for every term.
Therefore, relationship will be proportional.

Answer:
c. m∠2 = m∠5
Step-by-step explanation:
We can check 1 by 1 and find the false one.
For answer A, measures 2 and 4 are vertical angles, which means they are equal, so that's not false.
For answer b, measures 4 and 8 are corresponding angles, since X and Y are parallel, so that's also not false.
For answer c, measures 2 and 5 are supplementary to each other, and since the transversal is not perpendicular to X nor Y, they are not equal, therefore, this is false, making that the answer.
For answer d, measure 2 and 6 are corresponding angles, so that's also not false.
Therefore, the answer must be c.

Respectivamente b) la probabilidad de que llueva mañana es de 0.40 y la probabilidad de que no llueva es 0.52 c) las probabilidades de que una impresora cometa 0,1,2,3 o 4 o más errores al imprimir un documento son 0.19, 0.34, -0.25, 0.43 y 0.29 respectivamente. d) al sacar una carta de una baraja en un solo intento la probabilidad de seleccionar un corazón es ¼, la probabilidad deseleccionar una carta negra es ½, y la probabilidad de seleccionar una carta de corazones y negra es de 1/8
Answer:
Step-by-step explanation:
a) Si se suman las probabilidades de venta, es decir:
Probabildad de vender 0 auto ( es decir que no vendió) = 0,19
Probabildad de vender 1 auto = 0,38
Probabildad de vender 2 autos = 0,29
Probabildad de vender 3 autos =0,15
Da por resultado: 1,01
1,01 > 1
Ninguna probabilidad puede ser mayor que
b) LLover y no llover son condiciones excluyentes en relación al evento, es decir en relación a lluvia cualquier día o llueve o no llueve de tal forma

c) No existen probabilidades negativas ( en este caso señalan -0,25 como una probabilidad
d) La probabilidad de sacar una carta de corazones es 1/4 (correcta pues hay la misma cantidad de carta de las cuatro viras tipo ( diamante, trebo, corazones y el otro).
La mitad de las cartas son negras, de tal modo que 1/2 es correcto valor para esta probabilidad.
La probabilidad de que sea corazones y negra s 1/4*1/2 = 1/8

3/5 (2m-10)=2/3m+10
Answer:
m = 30
Step-by-step explanation:
3/5 (2m-10)=2/3m+10
Distribute
6/5 m - 6 = 2/3m +10
Subtract 2/3 m from each side
6/5 m - 2/3 m - 6 = 2/3m -2/3m +10
6/5 m -2/3m - 6 = 10
Add 6 to each side
6/5 m -2/3m - 6+6 = 10+6
6/5m -2/3m = 16
Get a common denominator of 15
18/15 m - 10/15 m =16
8/15 m = 16
Multiply each side by 15/8
15/8 *8/15 m = 16*15/8
m = 30

Rafael can choose plan a or Plan B for his long-distance charges. For each plan, cost (in dollars) depends on minutes used (Per month) as shown below.
Answer:
a. Plan B; $4
b. 160 mins; Plan B
Step-by-step explanation:
a. Cost of Plan A for 80 minutes:
Find 80 on the x axis, and trave it up to to intercept the blue line (for Plan A). Check the y axis to see the value of y at this point. Thus:
f(80) = 8
This means Plan A will cost $8 for Rafael to 80 mins of long distance call per month.
Also, find the cost per month for 80 mins for Plan B. Use the same procedure as used in finding cost for plan A.
Plan B will cost $12.
Therefore, Plan B cost more.
Plan B cost $4 more than Plan A ($12 - $8 = $4)
b. Number of minutes that the two will cost the same is the number of minutes at the point where the two lines intercept = 160 minutes.
At 160 minutes, they both cost $16
The plan that will cost less if the time spent exceeds 160 minutes is Plan B.
