hey... and what was that number 'n' for the perfect square ?

 

[acidglow]

Attention Everyone !!!!! plz plz plz can any one tell me tht usually what percentage makes an A in maths.....plz reply soon

 

[momen]

nd what was the acceleration?

0.66 m/s^2

80 percent minimum

 

[Aizen]

nd what was the acceleration?

0.66 m/s^2

are u sure....cuz i got 0.66 but two of my frnds said that they got 0.75....

Can anyone please tell me the answer for that question in which we had to find 'n' ?????? to make 168n a perfect square

i wrote reflection in x-axis and
1 0
0 1


is this acceptable ?

cant remember but think it was 6 x 7=42


not sure

 

[Aizen]

i dun think so...

 

[momen]

of how many marks question was the string one ?
any one knows

 

[Aizen]

was acceleration 0.66 or 0.75????

 

[momen]

0.66 ms^2

 

[Abdullahkhan92]

168n ............... n = 42.......... I think cambridge is trynna screw us by givin easy papers.!!!!!!!!!!!!!!!!!!!! X.X...... they are pushing the percentile to the sky so that normal students cant get A*s...... X.X.

 

[book worm]

Acceleration was .75 m/s2 ( 11.5 - 4 / 20 - 10)
but in case of drawing a tangent,many variations can be seen in an answer

 

[M.Usman Khan]

n=42=2 x 3 x 7

my acceleration is 0.75
some of friends also got 0.8 and 0.7
the correct values would b more than one.

 

[momen]

nd what was the acceleration?

0.66 m/s^2

are u sure....cuz i got 0.66 but two of my frnds said that they got 0.75....

0.66 is correct confirmed .!
but in marking scheme a range would be given aswell.!
