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
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 angle sum of a triangle will always be equal to 180°.
The angle sum of a quadrilateral is equal to 360°
And a triangle can be created by slicing a quadrilateral in half from corner to corner. Since a triangle is essentially half of a quadrilateral
Its angle measures should be half as well. Half of 360° is 180°

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 3 + 4 = 7 Step 2: Calculate the value of one part Each part of the ratio represents:
text{Value of one part} = frac{text{Total students}}{text{Sum of ratio parts}} = frac{28}{7} = 4 Value of one part = Total students/ Sum of ratio parts = 28 /7= 4 Step 3: Find the number of boys The boys' share is 3 parts , so:
text{Number of boys} = 3 times 4 = 12 Number of boys = 3 × 4 = 12

اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
To find how many more men are needed, we can use the formula for work:
Work = Men × Days text{Work} = text{Men} times text{Days} Work = Men × Days
Initially, 120 men can complete the work in 90 days. The total work can be represented as:
120 × 90 = 10800 man-days 120 times 90 = 10800 text{ man-days}
Now, we need to find how many men are needed to complete the work in 40 days:
Required Men = 10800 40 = 270 men text{Required Men} = frac{10800}{40} = 270 text{ men}

اس سوال کو وضاحت کے ساتھ پڑھیں
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.
