Casualties: over 50, 000

Explanation

When a square is rotated by 90 degrees, it still remains a square.

The shape of the square does not change because it has equal sides and 90-degree angles, regardless of its orientation.

Explanation

Pythagoras is considered the founder of the basic laws of geometry.

His work, particularly the Pythagorean theorem.

This laid foundational principles for the study of geometry.

Explanation

A group generated by one of its elements is called a cyclic group.

This means that the group can be generated by repeatedly applying the group operation to a single element, called the generator.

In other words, all elements of the group can be expressed as powers of the generator.

Explanation

x + y = 30 ... (Equation 1)

x - y = 8 ... (Equation 2)

We can solve these equations by adding them together, which eliminates y:

2x = 38

Dividing both sides by 2 gives us:

x = 19

Now that we have x, we can find y by substituting x into Equation 1:

19 + y = 30

Subtracting 19 from both sides gives us:

y = 11

Now that we have both x and y, we can find their product:

Product = x * y

= 19 * 11

= 209

Explanation

The ratio of boys to girls is given as 3:4, and the total number of students in the class is 28.

Step 1: Add the parts of the ratio

Step 2: Calculate the value of one part

Each part of the ratio represents:

Step 3: Find the number of boys

The boys' share is 3 parts, so:

Explanation

Average is equal to sum of all numbers and divided by Total numbers

= 9+18+27+36+45 = 135/5

=27

Explanation

To form a differential equation from a given function containing arbitrary constants:

• If the function has 'n' arbitrary constants, differentiate the equation 'n' times with respect to the independent variable.
• This process removes the arbitrary constants, leaving a differential equation.
