If the side length of the original tile is x, then the area is length * width, or x*x which is x^2. That's the first box up there. The new length is x - 4, since the length is what he cut away from. That's the second box up there. The width is still x, so the third box is x, and the area removed is 4x, the last box. So here's your info: box 1: x^2; box 2: x - 4; box 3: x; box 4: 4x
Just isolate y! Since the slope-point formula is y = mx + b, looking at your m determines if it's negative or positive! You can always graph the equation to check, but it's usually easier to look at the formula.
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
