The area of a trapeziod is found by adding the top and bottom dimensions together, dividing that by 2, then multiplying by the height.
The top half of the window is: 16 +30 = 46/2 = 23 x 276 square inches.
The top and bottom are the same.
Total area = 276 + 276 = 552 in^2
Answer: 9 (2 mark question) and 18 (5 marks questions)
Step-by-step explanation:
Given: Total mark = 108
Let the 2 marks questions be x
Therefore 5 mark question = 2x
ATQ
⇒5(2x)+2(x) = 108
⇒10x+2x =108
⇒12x = 108
⇒x = 108/12
⇒x = 9
Total two mark questions are 9 and 5 mark questions are 18.

Let

be the

th partial sum of a geometric sequence with common ratio

and first term

. So the sequence is

, and

is

Multiplying both sides by

gives

and subtracting

from

gives



If

, then

as

and so the sum approaches
