[raysonzaffar]

paper 580/42
--cake stuff area.........59.9cm2
--next page simultaneous equation..........$0.85.... &.....$0.55
--the linear programming....least possible cost for 20 trees was.........$145.....co-ordinates ( 9,11)
--probability.............9/14............and 14/25,,,,,,,,,,,,,,,,,,,,(i am not sure about the real values)
--the question right after the cake one .........length AD or AB...............is 37.9 cm
--the circle theorems were 132, 42 etc degrees (as far as i remember)
--the time thing in days and hours using the distance and speed given in standard form.......was 154 days 4 hrs....(i got 3700 hrs, divided it by 24 to get 154.1667 i changed 154 days...and 0.16667x24 which gave me 4 hrs )
--and the locus 1 was da angle bisector ryt !!!!!!!!!!!!!!!!!!!!!!!!

HELL YEA GOT SM OF MY ANSWERSRYT N SM WRONG NVM

 

[raysonzaffar]

pls let me know if i am wrong !!!!!!!!!!!!!!!!

 

[raysonzaffar]

The angle Was 22
The Radius Was 12
The height Was 7

only the upper part and the curved area had choclate

Pie x 12^2 x 22/360 + Pie x 2 x 12 x 7 x 22/360 =59.89969993 rounded to 59.9cm^2​

Dudes! Remember the loci question. More than 5.5cm from F. Did you draw the loci of points in broken lines? Because it said "more than" its strict inequalitt

One of the answers on the question paper 4 is wrong.
Question 6 - whoever solved it wrote x-110 instead of x-10 in their calculations, thus distorting the answer.
It should be 2x+x+114+x-10=360
4x= 246
x=64

Edit: Didn't want to double post but thought I'd add, stop worrying about exams you've already taken. You'll get your results in august. You should be focusing on the exams which you're about to take ( I mean, chemistry paper 6 tomorrow...). There's nothing you can do to change and if you in fact find that you got some questions wrong all it will do is leave you in a negative mood which will effect your other exams...
