Well I tlhought of dividing 85 first by 3 then I got the limits I am not convinced that I should directly divide it by 3 after getting the limits of perimeterDivide 84.5 by 3, you get 28.167 = 28.2 cm
Divide 85.5 by 3, you get 28.500 = 28.5 cm
How are you getting 28.7 and 28.8?

cross multiplyThe answer in the book is 1/3(a+b) I don't know how to work it out
you can multiply eq 1 by 2 or 4 if u wish....http://papers.xtremepapers.com/CIE/Cambridge IGCSE/Mathematics (0580)/0580_s07_qp_4.pdf
question 9 part c (ii) why we have to equalise the equation with 14 I thought of equalising it with 12 instead of 14.
OMG this question had come in our exams and i loved ithow to solve question 18 m/j 2014 p22 plzz help!!View attachment 48349
Make w the subject of the formula?Find the value of w when X^75 ÷X^w = x^8
There are 9 pencils, so there are 9C2 = 9x8/2 = 36 ways to pick 2 pencils.A box contains 3 red pencils, 2 blue pencils and 4 green pencils.
Raj chooses 2 pencils at random, without replacement.
Calculate the probability that: Exactly one for the two chosen pencils is green.
Thought blocker
(x^75)/(x^8)=x^wFind the value of w when X^75 ÷X^w = x^8
Thanks a tonThere are 9 pencils, so there are 9C2 = 9x8/2 = 36 ways to pick 2 pencils.
To get exactly 1 green pencil, there is 1 green and 1 other.
Raj picks from 4 green and 5 others.
There are 4 ways to pick one green and 5 ways to pick the other.
4x5 = 20 ways to pick exactly 1 green
20/36 = 5/9
You're welcome.Thanks a ton![]()
OMG this question had come in our exams and i loved it
See, throughout, we apply the principle that Volume = Area * length ( whatever length of cross-section... ), and step-by-step, we find each of the variables for both the containers.
For the large container, we have the volume and area, so let's find its length-
Volume = area * length
3456 = 1024 * length
length = 3.375 cm
For the smaller container, we will first find its length in order to get its area, by comparing its values with the bigger shape as they both are similar.
Using the formula V1/v2 = (length1/length2)^3, we substitute (the formula is somewhat that, i don't know how you write it)
3456/1458 = (3.375/length2)^3
length2 = 2.53125 (don't cut off decimal numbers even after three decimal places. Use the calculator to work out the answer)
Now you have the length as well as the volume for the smaller container,
Volume = area * length
1458 = area * 2.53125
area = 576
Erm... i hope you got it :/
No it says to find the value of w I did it and the answer which I got was 67 while the answer in the markschene is 64Make w the subject of the formula?
