Explanation

If the average of 20 numbers is zero, their total sum is zero.  

To maximize the number of values greater than zero,  

→ assume only one value is negative,  

→ and the sum of the 19 positive numbers is exactly cancelled by that one negative number.

So, at most 19 numbers can be greater than zero. 

Explanation

In geometry, the area enclosed by a circle of radius r is πr2

Arear of the circle: πR2

The perimeter of the circle: C = 2πR

Symmetry group: O(2)‎

Explanation

= 20/100 x 250

= 50

Explanation

Step 1:

Initial movement North. The man starts at a point and walks 3 km towards the North.

After this displacement, he is facing the North direction. 

Step 2:

First turn and movement He turns left from the North direction.

A left turn from North corresponds to the West direction.

He then walks  2 km in this direction. 

Step 3:

Second turn and movement.

While facing West, he turns left again.

A left turn from West corresponds to the South direction.

He walks 3km South, which brings him to the same horizontal level as his starting point. 

Step 4: Final turn and direction

From the South direction, he turns right.

A right turn from South corresponds to the West direction.

He continues to walk straight in this final direction. 

The man is walking in the West direction. 

Explanation

If one angle of an isosceles triangle is 68°, then:

- If 68° is the vertex angle, the other two equal angles = (180 - 68) / 2 = 56°  

- If 68° is one of the equal base angles, then the vertex angle = 180 - 2×68 = 44°

So, possible values for the second angle are 44° or 56° 

Explanation

Angular velocity is positive when the rotation is counter clockwise and negative when it is clockwise

Explanation

From the diagram let's take P as your initial position, first, you go 90-degree clockwise direction and reach Q, 

Then from Q you goes 180 degree anticlockwise and reaches R. 

From R you go again anticlockwise direction and reach S, Which is the final position and you facing is facing South-East
