Given that

Joe drinks 0.55 l of milk every day and we have to find the milk he can drink in 5 days.

Explanation -

Let the given condition be represented as

1 day = 0.55 L milk

So multiplying by 5 on both sides we have

1 x 5 days = 0.55 x 5 L milk

5 days = 2.75 L milk

And conversion is

1L = 1000 ml

So multiplying by 2.75 in the above equation we have

2.75L = 2.75 x 1000 ml = 2750 ml

So Joe will drink 2750 ml of milk in 5 days.

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.

Solution;

The events are independent

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:

Plan B has a fixed fee of $15 and a cost per day of $25:

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:

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.

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°

Given:

Yes, Tim is correct.

Expression is having the square so , wheather the input is negative or positive the output will always gives the positive values.

All real inputs will give the positive output.

Example:

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.
