Answer:
Therefor it is clear that the percentage of first year student like to listen classical music is less than 10 %
Step-by-step explanation:
Given as ;
The total number of first year students in an university = 250
The number of student who like to listen classical music = 12 out of 250
Let x % of student like to listen classical music
So, x% of 250 = 12
or, 
× 250 = 12
or, x × 250 = 12 × 100
Or, x = 
∴ x = 4.8
I.e the percentage of first year student like to listen classical music is 4.8%
Now, Again
The 10% of the total number of student is
I.e 10% of 250
or, 
× 250
Or , 
I.e The 10% of the total number of student = 25
Since 4.8 % of total number of students is 12 and 10% of total number of students is 25
Therefor it is clear that the percentage of first year student like to listen classical music is less than 10 % . answer
Answer and Step-by-step explanation:
a - b = 2
= 
b = a - 2
a = b + 2
______________
b = b + 2 - 2
b = b
______________
______________
a = a - 2 + 2
a = a
______________
If a equals 0, then the expression is undefined.
If b = 0, then the expression is 0.
There are infinite number of solutions when a is not 0 and the numbers are positive.

A= P(1+r)^t, where P= initial value, r= interest rate in %, and t = number of years.
However, if there isa decrease in value, the formula becomes:
A= P(1-r)^t and in our case :
A = 30,000(1- 0.24)^t OR A = 30,000(0.76)^t
The area of the banner, expressed in simplest form, is: <em>(9 + 3x) ft²</em>
<h3>How to Determine the Area of a Rectangle</h3>
- The area of a rectangle = length × width
The banner given in the image below has a rectangular shape. So, the area of the banner will be determined using the area of a rectangle.
- length = (3 + x) ft
- width = 3 ft
Area of the banner = (3 + x)3
Area = (9 + 3x) ft²
Therefore, the area of the banner, expressed in simplest form, is: <em>(9 + 3x) ft²</em>
