No 8 x 7.5 ! U have to take upper bound !
oh my bad ..correct !!

No 8 x 7.5 ! U have to take upper bound !
they have asked for what? the smallest width that can ALWAYS hold 8 pencils, right? so we have to take the upper bound of the pencils's diameter. this is because if we take the lower bound of the pencils,6.5mm, the box could not hold 8 pencils if their actual diameter was more than 6.5 (which is totally possible) eg 7.5mm. what will happen then? the box could not hold 8 pencils. so in order for the box to hold the 8 pencils in ANY CASE, we will take upper bound of the diameter, ie 7.5mm7.5mm*8 = 60 mm = 6 cm
yup6 cm answer hai iska.. ??
Ohk but u got explanation now

for question 9 get the two equation you can easily deduce that one is y=3 and the shaded part is below it means lesser so it will be y<3 and for the other you can see that the equation which is already given has a intercept off -2 and you can deduce this line on the graph okay now you have to find the equation of third line take any two points from that line find gradient and equation from y-y1=m(x-x1) and the shaded area is on the right side so it means greater so we'll use > for that equation. hope you got!http://www.xtremepapers.com/papers/CIE/Cambridge International O Level/Mathematics D (Calculator Version) (4024)/4024_s11_qp_12.pdf

its simple..just remove _ms
and place in _qp_1...
hy the 2 58s???180-58-58
because "AB bisects FAC"w

thankufor question 9 get the two equation you can easily deduce that one is y=3 and the shaded part is below it means lesser so it will be y<3 and for the other you can see that the equation which is already given has a intercept off -2 and you can deduce this line on the graph okay now you have to find the equation of third line take any two points from that line find gradient and equation from y-y1=m(x-x1) and the shaded area is on the right side so it means greater so we'll use > for that equation. hope you got!
thanx man appreciate itbecause "AB bisects FAC"
the line b is bisecting FAC so the two angles will be same . add them and subtract from 180 you'll get the answer
yeah i got it!!the line b is bisecting FAC so the two angles will be same . add them and subtract from 180 you'll get the answer
For almost 10 years, the site XtremePapers has been trying very hard to serve its users.
However, we are now struggling to cover its operational costs due to unforeseen circumstances. If we helped you in any way, kindly contribute and be the part of this effort. No act of kindness, no matter how small, is ever wasted.
