Given:
Number of students = 35
Two out of every five boys in the club are boys.
To find:
The number of students in the club that are boys.
Solution:
Two out of every five boys in the club are boys. It means, the ratio of boys to the total number of student is 2:5.
Let the number of boys be 2x and number of students be 5x.
According to the question,
Now, the number of boys is
Therefore, 14 students in the club are boys.
Answer:
A. 4 (RootIndex 3 StartRoot 7 x EndRoot) or
Step-by-step explanation:
Given:
A radical whose value is,
Now, we need to find the like radical for .
Let the like radical be .
As per the definition of like radicals, like radicals are those that can be expressed as multiples of each other.
So, if two radicals are like radicals, then
Where, 'n' is a real number.
Here,
Now, let us check all the options .
Option A:
4 (RootIndex 3 StartRoot 7 x EndRoot) or
Now, we observe that is a multiple of
because
Therefore, option A is correct.
Option B:
StartRoot 7 x EndRoot or
As the above radical is square root and not a cubic root, this option is incorrect.
Option C:
x (RootIndex 3 StartRoot 7 EndRoot) or
As the term inside the cubic root is not same as that of , this option is also incorrect.
Option D:
7 StartRoot x EndRoot or
As the above radical is square root and not a cubic root, this option is incorrect.
Therefore, the like radical is option (A) only.
