What is the congruence correspondence, if any, that
will prove the given triangles congruent?
A) ASA
B)SAS
C) SSS
D) none
Answer:
A) ASA
Step-by-step explanation:
You want to know the relevant congruence postulate given the markings of angles and sides shown in the diagram.
MarkingsThe arc and hash marks show on the angles mean the angles with matching markings are congruent. Two angles are shown as congruent to their corresponding angles in the other triangle.
The hash mark on the sides mean the sides with matching markings are congruent. One side between the marked angles is shown as congruent to the corresponding side in the other triangle.
The letters A and S in the congruence postulate designations refer to corresponding Angles and Sides, respectively. So, two angles with a side between them would be identified as ASA.
The ASA congruence postulate applies.
Option A) ASA is the correct answer for the given triangle in the question. ASA is the congruence correspondence.
What is congruence correspondence?
Each triangle's vertices must match one another exactly. This expression signifies that each triangle's side and angle measurements match up with a side or angle of the other triangle. To have a one-to-one correspondence, triangles don't necessarily have to be congruent, but when they are, knowing the correspondence of the triangles is important to determine precisely which sides and which angles are congruent.
According to congruence postulate,
Angles with matching markings are congruent if an arc or hash mark appears on them. The relationship between two angles and the corresponding angles in the other triangle is demonstrated.
The hash marks on the sides indicate that the markings on the sides that match are consistent. The opposite triangle's equivalent side is shown to be congruent to the side between the highlighted angles.
The congruence postulate designations begin with the letters A and S, which stand for matching Angles and Sides, respectively. Therefore, ASA would be used to describe two angles with a side in between them.

which statement would justify selecting plan B instead of plan A?Plan A: C = 30dPlan B: C = 25d + 15
We have two rental car plans.
We have to compare them to find the one that offers the minimum cost.
Plan A has no fixed fee but has a cost of $30 per day:
[tex]C=30d[/tex]Plan B has a fixed fee of $15 and a cost per day of $25:
[tex]C=25d+15[/tex]We expect the plan A to have a smaller cost for few days, while plan B becomes more convenient when we increase the number of days.
We can calculate the break even point when both costs are the same:
[tex]\begin{gathered} C_A=C_B \\ 30d=25d+15 \\ 30d-25d=15 \\ 5d=15 \\ d=\frac{15}{3} \\ d=5 \end{gathered}[/tex]Then, we know that for less than 5 days, Plan A is more convenient.
For more than 5 days, Plan B is more convenient.
For exactly 5 days, the decision is indifferent as both plans will have the same total cost.
Answer: The only statement that would justify selecting Plan B instead of A is if Marcus rents a car for 5 days.

Answer:
this is true
Step-by-step explanation:
Find a point N on the segment with endpoints K(-2, -3) and L(4,3) that partitions thesegment, starting at point K, 1/3 of the way to point L.
First find the length of the segment KL
Apply the formula for distance between two points as;
d = √{y2-y1}^2 + {x2-x1}^2 where
y1= -3 , y2 = 3 , x1 = -2 and x2 = 4
d= √ {3--3}^2 + { 4--2}^2
d= √ 9^2 + 6^2
d= √ 81 + 12
d= √93 = 9.6
So the length of the segment is 9.6
From point K {-2, -3} , find 1/3 of the length to locate point L
This will be : 1/3 * 9.6 =3.2
This means point L is 3.2 units from point K, now apply the distance formula to find x and y coordinates for L, where K is {-2,-3} and L {x,y}
d = √{y2-y1}^2 + {x2-x1}^2
3.2 = √{y--3}^2 + {x--2}^2
3.2 =√ {y+3}^2 +{x+2}^2
3.2^2 = {y+3}^2 + {x+2}^2
10.3 = y^2 + 6y + 9 + x^2 +4x +4
10.3 = y^2 + 6y +x^2 +4x +9+4
10.3 = y^2 + 6y +x^2 +4x +13
0=y^2 +6y +x^2 +4x +13-10.3
0= y^2 +6y +x^2 +4x +2.7
y^2 + 6y +x^2 +4x +2.7 = 0

Give an example of a proportional relationship and write an equation that represents the relationship.
The proportional relationship is represented by the formula, y = kx, which demonstrates that y increases at the same rate as x does
Relationships between two variables that are proportional occur when their ratios are equal.
Another way to consider them is that in a proportionate relationship, one variable is consistently equal to the other's constant value. The "constant of proportionality" is the name of this constant.The ratio of the constant values of two proportional quantities is known as the proportionality constant.When either the ratio or product of two changing values results in a constant, that pair of values is said to be in proportion.The Direct Variation and Inverse Variation types of proportions between the two provided values determine the value of the proportionality constant.The direct proportionality formula, y = kx, demonstrates that y increases at the same rate as x does. The cost per item (y), which is inversely proportional to the number of things purchased (x), is represented by the symbol y x.By using the indirect proportionality formula, y = k/x, it can be seen that when y rises, x falls, and vice versa.Therefore the proportional relationship is represented by the formula,
y = kx .

Lily needs 3/2 cup of sugar to make 4 cups of kool-aid.
What is Ratio?The ratio is defined as a relationship between two quantities, it is expressed as one divided by the other.
Lily is making kool-aid. She uses 1/4 cup of sugar for every 2/3 cup of kool-aid which is given in the question.
We have to determine the number of cups of sugar she needs to make 4 cups of kool-aid.
Let the number of cups of sugar would be x she needs to make 4 cups of kool-aid.
As per the given information, we can write the ratio as:
1/4 cup of sugar : 2/3 cup of kool-aid = x cup of sugar : 4 cup of kool-aid
⇒ 1/4 ÷ 2/3 = x ÷ 4
⇒ (1/4) / (2/3) = x / 4
⇒ (1/4) × (3/2) = x / 4
⇒ 3/8= x / 4
⇒ x = (3 × 4)/8
⇒ x = 12/8
⇒ x = 3/2
Therefore, she needs 3/2 cups of sugar to make 4 cups of kool-aid.

IQR(interquartile range) is the difference between the third and first quartile.
The range of a set of data is the difference between the largest and smallest values. The difference is specific; the range of a set of data is the result of subtracting the sample maximum and minimum.
Range = Maximum value - Minimum value
Range = 23 - 02 = 21

From the information given about the above quadrilateral, that is, the rectangle x is equal to 4, and m∠VUR is equal to 36°.
What is a quadrilateral?A quadrilateral is a four-sided polygon with four edges and four corners in geometry. The name comes from the Latin words quadri, a variation of four, and latus, which means "side."
The results above are derived as follows:
To find x note that the diagonals of a triangle are congruent. This means that RT = SU.
⇒ 3x + 8 = 6x - 4 (add 4 to both sides)
3x + 8 + 4 = 6x - 4 + 4
3x + 12 = 6x (Collect like terms over the equation sign)
12 = 6x - 3x
12 = 3x (divide both sides by three)
x = 12/3
x = 4
To derive m∠VUR,
Recall the properties of a rectangle:
Opposites sides a parallelOpposite sides are equalAll internal angles measure 90°The diagonals of a rectangle are equal.Also, note that;
SRU = 90°
hence
∠VRU = ∠SRU - ∠VRS
that is:
∠VRU = 90 -54 = 36°
If ∠VRU = 36°, then
∠VUR = 36° [The diagonals of a rectangle are equal.]
Hence ΔRVU is an Isosceles triangle. Since this is true, and it is also true that the two angles opposite to the equal sides of an isosceles triangle are congruent to each other,
Then indeed, ∠VUR = 36°

Given:
Mr. McClary writes the equation 3(3x - 10) = 5(x + 10). The equation shows the relationship between the perimeter of an equilateral triangle and the perimeter of a regular pentagon.
3(3x-10) = 5(x+10)
9x - 30 = 5x + 50
9x - 5x = 30 + 50
4x = 80
divide by 4 on both sides
4x/4 = 80/4
x = 80/4
x = 20.
perimeter of pentagon = 5(x+10)

The owner of two hotels is ordering towels. He bought 24 hand towels and 5 bath towels for his hotel in Washington, spending a total of $151. He also ordered 26 hand towels and 66 bath towels for his hotel in Lancaster, spending $830. How much does each towel cost?
The first step is to state the system of equations that represent this situation.
Let x and y be the cost of a hand towel and a bath towel respectively.
The equation that represents the money spent for the towels of the hotel in Washington is:
[tex]24x+5y=151[/tex]The equation that represents the money spent for the towels of the hotel in Lancaster is:
[tex]26x+66y=830[/tex]Solve the given system of equations by equalization:
[tex]\begin{gathered} y=\frac{151-24x}{5} \\ y=\frac{830-26x}{66} \\ \frac{151-24x}{5}=\frac{830-26x}{66} \\ 66(151-24x)=5(830-26x) \\ 9966-1584x=4150-130x \\ 1584x-130x=9966-4150 \\ 1454x=5816 \\ x=\frac{5816}{1454} \\ x=4 \end{gathered}[/tex]It means that a hand towel costs $4.
