The perimeter of pentagon is 150 so option D is correct.

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)

= 5(20+10)

= 5*30

= 150.

Therefore the perimeter of pentagon is 150 so option D is correct.

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

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.

The 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.

Find the area of each room and then add the three areas.

The total square footage to be covered is 459.

Since each square yard has 9 square feet, divide the square footage by 9 to find how many yards is that equal to:

Then, the area is equal to 51 square yards.

The cost for each square yard is $25.56. Multiply that amount by 51 to find the total cost:

The total cost for the carpeting is $1303.56.

Each roll of padding has 30 square yards. Since 51 yards must be covered, and two rolls would yield 60 square yards, then, the minimum amount of rolls needed is 2.

The cost for 2 rolls would be 2*$99 = $198.

Add the cost of the two rolls of padding and the carpeting job to find the total cost:

Then, the total cost of the carpeting job including the carpet and padding would be $1501.56.

Therefore, the answers are:

Part 1) 459 square feet.

Part 4) 2 rolls for $198

Part 5) $1501.56

From the information given about the above quadrilateral, that is, the rectangle x is equal to 4, and m∠VUR  is equal to 36°.

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:

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°

Lily needs 3/2 cup of sugar to make 4 cups of kool-aid.

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.
