Question
Point C is the centre of the circle above. What fraction of the area of the circle is the area of the shaded region?
The correct answer is: 0.27
HINT – Total angle covered by circle is 360°
SOLUTION – It is given that angle covered by shaded region = 100°
We know that total angle covered by a circle = 360°
So, the fraction of shaded region = 
= 
So, 
= 0.27 part of the circle is the area of shaded region.

A researcher surveyed 200 adults selected at random from the city of Aldley and 300 adults selected at random from the suburbs of Aldley. Each person surveyed was asked whether he or she owns a car. Some of the results are shown in the partially completed table below.
The researcher found that an adult surveyed in the suburbs of Aldley is twice as likely to own a car as an adult surveyed in the city of Aldley. Of the following, which could be the value of x ?

An equation is given in the form of ax + by + c=0. Here, 'a' and 'b' are real values and coefficients of x and y. Then, the equation is said to be a linear equation within the two variables. Examples of linear equations with two variables include x+4y = 3 and -x+5y = 2. Solution of a Linear Equation in 2 Variables: A pair of numbers (x, y), one for 'x' and the other for 'y,' that make the two sides of the equation equal. It is the solution of a linear equation in 2 variables. For instance, (0,4) is one of the answers if 2x + y = 4 since it satisfies the equation. A two-variable linear equation has infinite solutions.

For the function f, if f(3x) = x - 6 for all values of x, what is the value of f(6) ?
A function is defined as the relationship between a set of inputs and one output. In simple terms, it is a relationship between inputs in which each input corresponds to exactly one output. Every function has its domain and codomain, as well as a range. The general notation for a function is f(x), where x is the input. A function is represented as y = f(x).
¶Functions are the foundation of calculus in mathematics and represent the various types of relationships. A function is defined as a rule that produces a different output for each input x in mathematics. A function is denoted by mapping or transformation in mathematics.
