Q2,c{

$8 tickets =x
$5 tickets = 2x
$12 tickets = x+80
Total sum = 8(x) + 5(2x) + 12(x+80)
=30x + 960

30x + 960 = 9360
x=280

x is the no. of $8 tickets

Total no. of tickets sold = 280 + 2(280) + [280+80]
=1200

Q4.b)how to prove congruency?
Q10.b)How to show SR with that formula?I know we will use sine rule but it doesn't match up

4b Tr PSQ and TrPRQ are congruent as
One common side,namely PQ
PR=PS r of the smaller circle
SQ and RQ r of the larger circle
10b In Tr QPS 44+65 +36 +<QPR=180 giving QPR =35 so applying sine law in Tr QPR as stated it wont be a problem to get to the answer

QUESTION NO: Q3 b. I have calculated the area then divided by 2. Why is it wrong? And how come the answer's 10?
QUESTION NO: 8 both parts.
QUESTION NO: 9 part b
And when theres a question in sets and the ask n(abc) it means we have to write how many elements are there in this specific set right? We dont have to ADD all of the elements right???

Q 3 B )

Total Area is 48......... and Area of each box is 2*2 = 4

SO 48/4 = 12 anyway!

However, You will Notice that there is areas where it can reach anway like below

So there are two Boxess that cant be fitten unless cutted into half

So Ans. 10

Q 8 ) SORRY I HAVENT DONe BEARINGSS YET

Q9) Simply Median is some thing exactly between

So if 1 it is..............

Less than 1 Frequency is X and more is 5+4+2 =11

Thus, x must be 11 .. making 1 the median

I hope it helps ! )

Q3) Round down the odd numbers to even. 3 to 2 and 9 to 8. Then area becomes 40 cm2.
Area of a sqaure = 2 x 2 = 4 cm2 so 40/4 = 10 cm2

Q8) a)
