The sequence of transformations that can be performed on quadrilateral ABCD to show that it is congruent to quadrilateral is 90° counterclockwise rotation about point A followed by the reflection across y axis and a translation 20 units down.

It should be noted that a transformation simply illustrates the change in shape.

In this case, the sequence of transformations that can be performed on quadrilateral ABCD to show that it is congruent to quadrilateral is 90° counterclockwise rotation about point A.

This will then be followed by the reflection across y axis and a translation 20 units down.

Answer:

187 Points

Step-by-step explanation:

Total ratio units = 17 + 14 = 31 units

Total they scored = 341 points

Therefore total units = 31 = 341 points

31 units = 341 points

1 unit = (341/31) points

1 unit = 11 points

Nina scored 17 units of the total points

17 units = (17 x 11) points

= 187 points

The value of the relative frequency distribution of the first interval, having a frequency of 14, and the total frequency given is 40, is 0.35.

In a Relative Frequency Distribution, we list how often a data value appears and scale it using the total frequency.

The sum of Relative Frequencies adds to 1.

In the question, we are informed that the first interval has a frequency of 14.

This implies that the data appears 14 times in the first interval.

Also, we are told that the total frequency is 40.

Thus, the relative frequency can be calculated as the ratio of the frequency of the interval to the total frequency.

Therefore, Relative frequency = 14/40 = 0.35.

Thus, the value of the relative frequency distribution of the first interval, having a frequency of 14, and the total frequency given is 40, is 0.35.

The best buy is from dealership B because dealership B has a lesser base price

For the purpose of this exercise, the add-on options to select are:

The total amount of the add-on options is:

Total = $500 + $1500

Total = $2000

The inequality

This is represented using:

Base price * (1 + Tax) + Fees + Add-on total ≤ 20000

So, we have:

(1 + 6.75%) * x + 751.56 + 2000 ≤ 20000

Solve for x

We have:

(1 + 6.75%) * x + 751.56 + 2000 ≤ 20000

Evaluate the like terms

(1 + 6.75%) * x  ≤ 17248.44

Divide both sides by (1 + 6.75%)

x  ≤ 16157.79

The solution means that the base price of the car cannot exceed $16157.78 for dealership A

The graph of the possible base price

See attachment

The total amount of the add-on options is:

Total = $750 + $1000

Total = $1750

The inequality

This is represented using:

Base price * (1 + Tax) + Fees + Add-on total ≤ 20000

So, we have:

(1 + 6.75%) * x + 1524.72 + 1750 ≤ 20000

Solve for x

We have:

(1 + 6.75%) * x + 1524.72 + 1750 ≤ 20000

Evaluate the like terms

(1 + 6.75%) * x  ≤ 16725.28

Divide both sides by (1 + 6.75%)

x  ≤ 15667.71

The solution means that the base price of the car cannot exceed $15667.71 for dealership B

The measures of GX = 13

The measures of [tex]\angle ABX=22^0[/tex]

EX = 4z + 1  and XF = 2z + 7

Take EX and XF equal time each other and then solve for z and then you will get GX because EX = XF = GX are congruent.

EX = XF

Two figures or objects are congruent if they have the same shape and size, or if one has the same shape and size as the mirror image of the other.

4z + 1 = 2z + 7

2z = 6

z = 3

As,    EX = XF = GX

EX = 4(3) + 1

EX = 13

Therefore, GX = 13      ------      ( EX = XF = GX )

25 times 2.5 = 62.5

2.

3/7.5 = 25/x

3x = 187.5

187.5 ÷ 3 = 62.5

The actual distance for a length on a map is 62.5. so correct option is D.

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

The relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.

Given The scale on a map reads 3 inches = 25 miles.

If two cities are 7.5 inches apart on the map,

Find the actual distance for a length on a map.

Let x be the actual distance

7.5 ÷ 3 = 2.5

25 times 2.5 = 62.5

Thus,

3/7.5 = 25/x

3x = 187.5

187.5 ÷ 3 = 62.5
