Answer:
### What is a parallelogram?

### What is a triangle?

The **value **of x for the given **triangle **side in the **parallelogram **will be 4.

A basic **quadrilateral** with two sets of **parallel **sides is known as a parallelogram.

A parallelogram's **facing **or **opposing **sides are of **equal **length, and its opposing angles are of similar size.

A triangle is a closed, 2-dimensional shape with 3 sides, 3 angles, and 3 vertices.

The **area **of a **parallelogram **is given as,

(1/2)(**sum **of parallel sides)(**distance **between parallel lines)

Area of parallelogram = (1/2)(14 + 14)(10) = 140 square meter.

The **area **of the right angle **triangle **= (1/2)base x height.

Area of triangle = (1/2)x × 10 = 5x

**Total area** = 140 + 5x

160 = 140 + 5x

5x = 20

x = 4

Hence "The **value **of x for the given **triangle **side in the **parallelogram **will be 4".

Find the lower quartile and upper quartile of

the data set.

lower quartile: $

upper quartile: S

?

$1.39 $1.40 $1.44 $1.50 $1.60 $1.63 $1.65 $1.80

**Answer:**

Lower quartile: $1.42

Upper quartile: $1.64

**Step-by-step explanation:**

The **median **is the **middle value** when all data values are placed in order of size.

The ordered **data set** is:

$1.39 $1.40 $1.44 $1.50 $1.60 $1.63 $1.65 $1.80

There are** 8 data values** in the data set, so this is an** even data set**.

Therefore, the **median **is the **mean **of the **middle two values**:

Place "||" in the middle of the data set to signify where the median is:

$1.39 $1.40 $1.44 $1.50 ║ $1.60 $1.63 $1.65 $1.80

The** lower quartile **(Q₁) is the **median **of the **data points **to the **left **of the median. As there is an even number of data points to the left of the median, the lower quartile is the mean of the the middle two values:

The** upper quartile **(Q₃) is the **median **of the **data points **to the **right **of the median. As there is an even number of data points to the right of the median, the upper quartile is the mean of the the middle two values:

**Answer:**

to find the lower quartile and upper quartile of the given dataset, we need to first arrange the data in ascending order:

$1.39, 1.40, 1.44, 1.50, 1.60, 1.63, 1.65, 1.80$

The median of the dataset is given as $1.55$. Since there are an even number of data points, the median is the average of the two middle values, which in this case are $1.50$ and $1.60$.

Now, we need to find the lower quartile and upper quartile. The lower quartile is the median of the lower half of the data set, and the upper quartile is the median of the upper half of the data set.

The lower half of the dataset is $1.39, 1.40, 1.44, 1.50$. The median of this half is the average of the middle two values, which are $1.40$ and $1.44$.

Therefore, the lower quartile is $1.42$.

The upper half of the dataset is $1.60, 1.63, 1.65, 1.80$. The median of this half is the average of the middle two values, which are $1.63$ and $1.65$.

Therefore, the upper quartile is $1.64$.

Hence, the lower quartile of the dataset is $1.42$ and the upper quartile is $1.64$.

**Answer:**

C. 0.045

**Step-by-step explanation:**

The **angles **of **rotation **that would **not map** the figure onto itself will **not **be the **multiple **of **40 **and this can be determined by evaluating the possible **angle **of **each rotation**.

Given :

- A nonagon is a nine-sided polygon.
- A regular nonagon was rotated about its center point.

To determine **angels **of **rotation **that would **not map **the figure onto **itself**, first, evaluate the **possible angle **of **each rotation**.

To determine the possible **angle **of **each rotation **the following calculation can be used:

The possible **angle **of **each****rotation **is the **ratio **of the complete **rotation **to the number of **sides**.

Each Rotation =

So, the **angles **of **rotation **that would **not map** the figure onto itself will **not **be the **multiple **of **40**.

**Answer:**

**Step-by-step explanation:**

**Given**

**Required**

Angles of rotation that would not map the shape on itself

Side of a nonagon is:

and a complete rotation is:

To start with, we calculate a possible angle of each rotation:

This is calculated by dividing the complete rotation by number of sides

**The question lacks option; so, it's difficult to give a specific answer.**

**However, I'll give a generalized answer**

For the nonagon to map on itself, the angle must be a multiple of the **calculated angle of rotation (40)**

**i.e.**

**Any angle different from the above listed angles (or any other multiple of 40 not listed above) answers the question.**

**Answer:**

x ≈ -1.585786438 or x ≈ -4.414213562

y = 7

**Step-by-step explanation:**

This should be a parabola function.

Let y = 0 so we can find the two x-intercepts. (x1,0) and (x2,0)

x^2+6x+7 = 0

Using the quadratic equation, we get:

x ≈ -1.585786438 or x ≈ -4.414213562

Now we can find y by setting x = 0, so that we get a y-intercept. (0,y)

y = 0^2+6(0)+7

y = 7

2. 5x+4y ≥20

**Answer**

2x-y <or =-6

2x<or=-6+y

divide both sides by 2

x<or=1/2y+3

5(1/2y+3)+4y>or=20

5/2y+15+4y>or=20

5/2y+4y>or=20-15

13/2y>or=5

divide both sides by 2/13

y>or=10/13

2x-10/13<or=-6

2x<or=-6+10/13

2x<or=-68/13

divide both sides by 2

x< or =-34/13
