Multiples of 10 are numbers like 10, 20, 30, 40, 50, 60, and so on.

In shape one you can see, it has only 1 line of symmetry horizontal line of symmetry

It has one line of symmetry. If you were to put a mirror on the vertical line shown below you would see the other side of the heart in the mirror. Two identical sides.

A rectangle has two lines of symmetry.

The next shape is a triangle. TRUE

The twelfth shape is a triangle.. TRUE

The sixteenth shape is a square.. FALSE
For every triangle, there are two squares. FALSE
The square is the second, fifth, and eighth shape. TRUE

Shapes B, C, and D have at least three lines of symmetry.

The word symmetry is the most commonly used concept in the study of reflections of mages. It is often referred to as mirror or reflective symmetry; that means a line or plane that can be drawn through an object such that the two halves are mirror images of each other.

47, 53, 59, 65

Because all the digits have a difference of 6 between them. 

The X has two lines of symmetry.

Correct option: B

Initial amount = $60.

Amount added per day = $5.

Amount added after d days = $5 × d.

Total after d days = $60 + $5 × d.

Set total equal to $100: $60 + $5 × d = $100.

Subtract $60 from both sides: $5 × d = $40.

Divide both sides by $5: d = 8.

Therefore, d = 8 and option B is correct.

Since the ball is falling down gradually in the box; the next pattern will be A. 

An image which is like a reflection in a mirror. Everything is the same, except reversed. Here the left and right sides of this lovely dog are mirror images of each other.

The next term will come by multiplying with number 2

12 *2 = 24,

24*2 = 48,

48*2 = 96,

96*2 = 192,

192*2 = 384

Each digit is double of its previous member of the series. 

4 + 4 = 8

8 + 8 = 16

16 + 16 = 32

32 + 32 = 64

64 + 64 = 128

128 + 128 = 256

The next number will be given by multiplying with 10 

3*10 = 30

30*10 = 300

300*10 = 3000

3000*10 = 30000

In the pattern, it can be seen that lines are increasing diagonally. 

The next pattern in the series will be D.

An image which is like a reflection in a mirror. Everything is the same, except reversed. Here the left and right sides of this lovely dog are mirror images of each other.

To solve this pyramid pattern, each block is typically calculated as the sum of the two blocks directly beneath it. Let’s analyze step by step:

1. Base layer:

   • Numbers are 11,12,13,1411, 12, 13, 1411,12,13,14.

2. Second layer:

   • 23=11+12,
   • 25=12+13,
   • 27=13+14.

3. Third layer:

   • 48=23+25,
   • Missing term (?) = 25+27=52.

4. Top layer:

   • 100=48+52.

Answer: The missing term is 52.

The missing figure is 14

A,B,C
All can be cut into mirror halves becaue these are symmetrical.
