Geometry: Quadrilateral LMNO is reflected over the line as shown, resulting in quadrilateral CDAB. Given the congruency statement LMNO ≅ CDAB. What segment corresponds to ML? (Show your work or explain your reasoning).
Answer: We are given Quadrilateral LMNO is reflected over a line.
Also given Quadrilateral LMNO is congruent Quadrilateral CDAB, that is
LMNO ≅ CDAB.
Note: Reflection over a line represents mirror images of the figures.
From the given image we can see
LM is congruent to CD.
ON is congruent to BA.
LO is congruent to BC.
MN is congruent to AD.
Therefore, DC segment corresponds to ML.
Hope i helped you out!
How to do this question plz answer
Step-by-step explanation:
a) m∠AOB = 360°/8 = 45°
Internal angle is 360°, divided by 8 sides of octagon
b) m∠ABC = 2m∠ABO
m∠ABO = m∠BAO = 1/2(180° - 45) = 1.2(135°)
m∠ABC = 2*1/2(135°) = 135°
Answer:
a) 45
b)135
Step-by-step explanation:
[tex]In\ order\ to\ find\ the\ sum\ of\ all\ the\ interior\ angles\ of\ a\ polygon\ with\ sides\ n,\\S=180(n-2)\\Here,\\As\ the\ figure\ is\ a\ regular\ octagon\ ,\\The\ sum\ of\ all\ of\ its\ angles\ = 180(8-2)\\=180*6=1080\\Hence,\\Given\ that\ it\ is\ regular\ or\ that\ all\ of\ its\ angles\ are\ equal\ in\ measure.\\Hence,\\b) Angle\ ABC=1080/8\\=135\\As\ it\ is\ regular\ , the\ diagonals\ passing\ through\ the\ center\ bisects\ the\ respective\ angles.[/tex]Hence,
[tex]Angle OAB=135/2 = 67.5\\Angle ABO=135/2=67.5\\Through\ the\ angle\ sum\ property\ of\ a\ triangle\\Angle OAB+AngleABO+Angle AOB=180\\67.5+67.5+AngleAOB=180\\135+AngleAOB=180\\Angle AOB=180-135\\=45[/tex]

At store A, 3 pounds of apples cost $12.
At store B, the cost is given by y = 2x where y is the cost in dollars and x is the number of pounds of apples.
The cost of apples at store C is shown in the graph.
Answer the questions to find out which store's apples are the least expensive.
1. What is the unit price of apples at store A? Explain how you found this unit price.
Write your answer in the space below.
2. What is the unit price of apples at store B? How did you use the equation to find the unit price?
Write your answer in the space below.
3. What is the unit price of apples at store C? How did you use the graph to find the unit price?
Write your answer in the space below.
4. Which store has the lowest unit price for apples?
Write your answer in the space below.
Answer:
The unit price is the cost per unit of an item or the cost/price for each item.
1) 4$ per pound. By simplifying the proportion (constant ratio) between the cost, and the pounds of apples. 3 pounds of apples cost 12$ → 3/3 pounds of apples cost 12/3$ → 4 dollars for every pound.
2) 2$ per pound. By evaluating the rate of change (change in the y over x or dependent variable over independent) in the equation: y = 2x. y is the cost in dollars, and x is the pounds of apples. So there are 2 pounds (weight) of apples for every dollar.
3) 3$ per pound. Given a graph with a y scaled by 3, and an x scaled by 1 with a graph y = x or 1 unit up for every unit right. This must be equivalent to y = 3x. Where y is labeled as the cost in dollars, and x as the weight in pounds. So there are 3 dollars for every pound of apples.
4) Store B. Because 2 is less than 3 which is less than 4.

Madhu bought a washing machine for Rs 13,000. He then sold it for Rs 15,000. He also paid Rs 300 to arrange the delivery of the washing machine at the buyer's house.
How much profit did Madhu make by selling the washing machine?
cost price=1300
selling price=1500
1500_1300=2000
madhu use 300 from his profit so
2000_300=1700
answer=1700

2(x+7) 2x + 20
- 2 =
x+4
2x + 8
Answer:
x = 0
Step-by-step explanation:
2(x+7) 2x + 20 - 2 = x+4(2x + 8) start by distributing
2(x+7) would be 2x+14
4(2x+8) would be 8x+32
2x+14 x 2x + 20 - 2 = x + 8x + 32 now combine like terms
2x and 2x can be combined on the left side
x and 8x can be combined on the right side
4x + 14 + 20 - 2 = x + 8x + 32
4x + 32 = 9x + 32 you can now solve this equation
start by subtracting 4x on both sides
32 = 5x +32 now subtract 32 on both sides
0 = 5x so x = 0
Answer:
x = 0
2(x+7) 2x + 20 - 2 = x+4(2x + 8) start by distributing
2(x+7) would be 2x+14
4(2x+8) would be 8x+32
2x+14 x 2x + 20 - 2 = x + 8x + 32 now combine like terms
2x and 2x can be combined on the left side
x and 8x can be combined on the right side
4x + 14 + 20 - 2 = x + 8x + 32
4x + 32 = 9x + 32 you can now solve this equation
start by subtracting 4x on both sides
32 = 5x +32 now subtract 32 on both sides
0 = 5x so x = 0

A group of friends receives a dinner bill for $87.50$87.50. The sales tax rate is 5%5%. They want to leave a 15%15% tip on the total bill after tax. How much money will they pay for their dinner with tax and tip?
Answer:
105.66
Step-by-step explanation:
87.5 times 1.05= 91.875
then you do 91.875 times 1.15 = 105.656
Answer:
I got $105.66
Step-by-step explanation:
I multiplied the subtotal by .05(to represent sales tax %) then added the solution to $87.50. then I multiplied .15(tip) to $87.50. Added that to the previous solution and got $105.66. Read below for clarification.
87.50(.05) = 4.375(or 4.38)
87.50 + 4.375 = 91.875
87.50(.15) = 13.125
91.875 + 13.125 = $105.66

The solution is, ΔABC ≅ ΔFDE by SAS congruence rule.
The correct option is (1).
What are congruent triangles?Congruence is a phrase used frequently in mathematics to refer to a harmonious connection, comprehension, or correlation. A geometric figure is said to be congruent or to be in the relation of congruence if it is feasible to superimpose it on another so that their whole surfaces match. Two triangles are said to be congruent when two sides and their included angles in one triangle are equal to two sides and their included angles in the other.
here, we have,
As per the given data:
In ΔABC :
∠A = 63°
AC = 2.2
In ΔFED :
∠F = 63°
FE = 2.2
By using the distance formula, we can find AB and FD.
From the coordinates, as we can see in the diagram
FD = 2 units
Similarly,
AB = 2 units
Now from SAS congruence rule:
AB = FD (Both are 2 units)
∠A = ∠F (given)
AC = FE (given)
Hence, ΔABC ≅ ΔFDE by SAS congruence rule.

CJ earned a score of 75% on his math quiz each question on the quiz worth one points in CJ got 18 question correct how many questions were on the quiz
Answer: 24 questions
Step-by-step explanation:
Let the number of questions on the quiz be represented by x. This means that 75% of x equals 18. We need to calculate x. This will be:
75% × x = 18
75/100 × x = 18
0.75 × x = 18
0.75x = 18
x = 18/0.75
x = 24
