Given:
Consider the below table attached with this question.
Every square meter of ceiling requires 10.75 tiles.
To find:
The missing values in the table.
Solution:
We have,
1 square meter of ceiling = 10.75 tiles. ...(i)
Therefore, the number of tiles corresponding to 1 square meter of ceiling is 10.75.
Multiply both sides by 10.
10×1 square meter of ceiling = 10×10.75 tiles.
10 square meter of ceiling = 107.5 tiles.
Therefore, the number of tiles corresponding to 10 square meter of ceiling is 107.5.
Divide both sides by 10.75 in (i).
square meter of ceiling = 1 tile.
Multiply both sides by 100.
square meter of ceiling = 100 tiles.
On approximating the value, we get
9.3 square meter of ceiling = 100 tiles.
Therefore, the square meters of ceiling corresponding to 100 tiles is about 9.3.
Multiply both sides by a in (i).
a×1 square meter of ceiling = a×10.75 tiles.
a square meter of ceiling = 10.75a tiles.
Therefore, the number of tiles corresponding to a square meter of ceiling is 10.75a.

Answer:
The correct option is c.
Step-by-step explanation:
The quotient of the polynomials is
We need to find the remainder by using long division method.
The dividend of the given expression is
The long division method is shown below.
From the below attachment it is clear that the quotient has a remainder of 30. Therefore, the divisor is not factor of the dividend.
Therefore the correct option is c.
