Answer:

The perimeter of the first question is 62

If you draw it, you'll you'll see that it's a rectangle. The length of each side is calculated by adding the widths and heights as in the photo ( red ), and then adding them up. 13 + 18 + 13 + 18 = 62

You do the same with question 2, but this time the rectangle is smaller. (green in the photo)

So the perimeter is:

13 + 14 + 13 + 14 = 54

The answer to question 3 is (-15, -5) as drawn in the photo.

Consider the vector add = a + b = [13 12 11 10 10] and sub = a - b = [-11 - 6 - 14 8]. Find the vector a and b.

prisoha [69]

Answer:

a = [1 3 5 7 9] and b = [12 9 6 3 1]

Step-by-step explanation:

The addition of two vectors a and b is defined as

a + b = [13 12 11 10 10] .... (1)

The subtraction of two vectors a and b is defined as

a - b = [-11 - 6 - 1 4 8] .... (2)

After adding (1) and (2), we get

(a + b) + (a - b)= [13 12 11 10 10] + [-11 - 6 - 1 4 8]

On simplification we get

2a = [13-11 12-6 11-1 10+4 10+8]

2a = [2 6 10 14 18]

Divide both sides by 2.

a = [1 3 5 7 9]

Substitute the value of vector a in equation (1).

[1 3 5 7 9] + b = [13 12 11 10 10]

Subtract vector a from both sides.

b = [13 12 11 10 10] - [1 3 5 7 9]

On simplification we get

b = [13-1 12-3 11-5 10-7 10-9]

b = [12 9 6 3 1]

Therefore the vectors a and b are defined as a = [1 3 5 7 9] and b = [12 9 6 3 1].

Which step in the construction of copying a line segment ensures that the new line segment has

Nesterboy [21]

The steps 5 and 6 in the construction of a new line segment ensures the lengths are equal.

A line segment in geometry has two different points on it that define its boundaries. Alternatively, we may define a line segment as a section of a line that joins two points.

Below are the steps for copying a line segment:

1. Let's begin with a line segment we need to copy, AB.

2. we take a point C at this stage. That will be one endpoint of the new line section, either below or above AB.

3. Now we place the the compass pointer on the point A of line segment AB.

4. We spread the compass out until point B, making sure that its breadth corresponds to the length of AB.

5. We place the compass tip on the point C created in step 2 without adjusting the compass's width.

6. We now draw a rough arc without adjusting the compass's settings. we add a point D oh the arc . The new line segment will be formed by this.

7. From C, draw a line to D;CD thus formed is equal to AB.

Hence steps 5 and 6 are the steps in the construction of a new line segment which ensures the lengths are equal.

Please someone can help me with question #9. Thanks

gavmur [86]

Given:
3 red dresses
2 white dresses
1 blue dresses

Probability that she will wear the blue dress at her party.

3 + 2 + 1 = 6 total number of outcomes.

There is only 1 blue dress so the number of ways it can happen is only 1.

probability of an event happening = number of ways it can happen / total number of outcomes

Probability = 1/6 or 0.166 or 16.6%
