Hi,
I've just taken paper 2 exam and I would like to know what did u did in the question about speeeeeeed????????!!!!!! and thAT ABOUT PT LENGHT.
plz answer me .

 

[A.W.H]

This is a tricky question , you will get the distance which is 130 meters , then use the 1/2 × b × h

1/2 * b * h = 130

i think the answer is 16.something

 

[niassu]

is anybody sure of this answer

 

[Giraffe195]

Those two were very difficult questions. I believe I missed both. I think you have to use Pythagoras theorem to solve it.

 

[Adham-amr]

it will be 16.25

answer is 16.3 correct to 3 significant figures. i used a physics formula for that distance=(speed x time)/2

 

[xiaotian]

the answer was 16.25 and the pt lenght question was to use pythagoras as the top part was a triangle!

does anyone know at what percent is an A* GRADE IN IGCSE MATH , an A and a B ???? plz reply

 

[Murad]

yes you have to score approximately 47 from 70 for an A )

 

[saheel]

r u sure about that grade boundry?? 47/70?? that is pretty simple to get

 

[Giraffe195]

it changes every now and then. I don't remember it ever going above 51 out of 70 up till 2006 though so that's good

Yeah I know Is it bad ? .. I've seen the mark schemes from last papers .. but it depends of how hard the paper was .. If Most of Candidates got low Grades Then it Could Be even 46/70 but if it is to easy they can set it 49/70 for example .
