Mathematics
2 answers:
telo118 [61]3 years ago
5 0

Step-by-step explanation:

Sets are represented in a Venn diagram by circles drawn inside a rectangle representing the universal set.

The region outside the circle represents the complement of the set.

The overlapping region of two circles represents the intersection of the two sets.

Two circles together represent the union of the two sets.

Answer:

There are a few things you need to know about sets . They are :

1.Sets are represented in a Venn diagram by circles which are drawn inside a rectangle (which represents the universal set).

2.The region outside the circle represents the complement of the set.

3.The overlapping region of two circles represents the intersection of the two sets.

4.Two circles together represent the union of the two sets.

5. Two sets are said to be disjoint sets if they do not share any common elements.

6. (see image ) B is a proper subset of A. This means B is a subset of A, but B ≠ A.

7. A is a proper superset of B. This means that A is a superset of B (all values of set B can be found in set A ) , but A≠B

Help anyone can help me do 16 and 17 question,I will mark brainlest.The no 16 question is find the area of the shaded region​
yanalaym [24]

Answer:

Question 16 = 22

Question 17 = 20 cm²

Step-by-step explanation:

<u>Concepts:</u>

Area of Square = s²

  • s = side

Area of Triangle = bh/2

  • b = base
  • h = height

Diagonals of the square are congruent and bisect each other, which forms a right angle with 90°

Segment addition postulate states that given 2 points A and C, a third point B lies on the line segment AC if and only if the distances between the points satisfy the equation AB + BC = AC.

<u>Solve:</u>

Question # 16

<em>Step One: Find the total area of two squares</em>

Large square: 5 × 5 = 25

Small square: 2 × 2 = 4

25 + 4 = 29

<em>Step Two: Find the area of the blank triangle</em>

b = 5 + 2 = 7

h = 2

A = bh / 2

A = (7) (2) / 2

A = 14 / 2

A = 7

<em>Step Three: Subtract the area of the blank triangle from the total area</em>

Total area = 29

Area of Square = 7

29 - 7 = 22

-----------------------------------------------------------

Question # 17

<em>Step One: Find the length of PT</em>

Given:

  • PR = 4 cm
  • RT = 6 cm

PT = PR + RT [Segment addition postulate]

PT = (4) + (6)

PT = 10 cm

<em>Step Two: Find the length of S to PT perpendicularly</em>

According to the diagonal are perpendicular to each other and congruent. Therefore, the length of S to PT perpendicularly is half of the diagonal

Length of Diagonal = 4 cm

4 ÷ 2 = 2 cm

<em>Step Three: Find the area of ΔPST</em>

b = PT = 10 cm

h = S to PT = 2 cm

A = bh / 2

A = (10)(2) / 2

A = 20 / 2

A = 10 cm²

<em>Step Four: Find the length of Q to PT perpendicularly</em>

Similar to step two, Q is the endpoint of one diagonal, and by definition, diagonals are perpendicular and congruent with each other. Therefore, the length of Q to PT perpendicularly is half of the diagonal.

Length of Diagonal = 4 cm

4 ÷ 2 = 2 cm

<em>Step Five: Find the area of ΔPQT</em>

b = PT = 10 cm

h = Q to PT = 2 cm

A = bh / 2

A = (10)(2) / 2

A = 20 / 2

A = 10 cm²

<em>Step Six: Combine area of two triangles to find the total area</em>

Area of ΔPST = 10 cm²

Area of ΔPQT = 10 cm²

10 + 10 = 20 cm²

Hope this helps!! :)

Gina bought 6 containers of yogurt for $4. how many containers of yogurt could gina buy for $12?
maw [93]
6 containers =    4$
  X containers  = 12 $

When you cross multiply , it will be 4X = 72

therefore X= 72/4= 18 . 

Or just use your logic for that answer , 12 /4 is 3 right? 
then multiply 6 by 3

1/2x plus 12 = 8x Please help me!
netineya [11]

Answer:

8/5=x

Step-by-step explanation:

1/2x+12=8x

Subtract 1/2x from both sides

12=15/2x

Multiply 2/15 on both sides

8/5=x
