27:24 maths is so picky why is it ordering us to work out an estimate when in reality it doesnt want it in an estimate because theyve already frickin estimated it

[@Rahim103.5]

i genuinely love you bro

[@mohamedifthikar1372]

35:44 don’t you have to expand the brackets of the denominator? Or will you gain the mark nonetheless?

[@girnogiovana6577]

you can leave it as that or expand you will get the mark anyway

[@user-qi1jf7io9f]

i love maths

[@obsolete9734]

i hope the questions on my exam are this easy lol

Thanks

[@j_shergill5698]

for the last question question 21 what is the topic called someone PLEASE tell me I was literally sitting there with no clue what to do
and if anyone knows the answer to this [ what would have happened if you used the normal method to work out area of a triangle in q 19 would it just not be the correct answer?

[@morro2955]

Think it’s probably like ratios topic

[@manlapyt3679]

Ratios using algebra

[@zenmarais8425]

This comment is old, however, for any future persons I will outline the relevant topics that worked for me.
1. Harder quadratics.
2. Ratios and harder ratio questions.
3. Algebraic ratios.
3. Gradients, although don't mix up the fact that (change in y)/(change in x) DISTINCTLY applies to STRAIGHT lines.
Now let's go through a worded problem:
Paul is a fruit vendor. Paul has found that for every 5 apples he sells, he sells 2 bananas. How many bananas has Paul sold if he sells 35 apples?
1. The ratio of apples to bananas is 5 : 2. So apples/bananas can be represented as 5/2.
(a) Apples = 5/2 * bananas. So if there are 2 bananas, 2 * 5/2 = 5.
(b) So dividing Apples by 5/2 will give us bananas, which i the same as multiplying by the reciprocal, Apples * 2/5 = bananas.
2. Carrrying on from apples/bananas = 5/2. We know that Paul has sold 35 apples. So we can rewrite that equation as 35/b = 5/2.
3. Then we can cross multiply. So 35 * 2 = 5 * bananas.
4. 70 = 5b.
5. Solving for b, 70/5 = 14. So when Paul has sold 35 apples, he has sold 14 bananas. 35 : 14, which divided by the HCF as 7 gives us 5 : 2.
After going through that, not that the ratio 5 : 2 means that 5/2 * bananas = apples. And 2/5 * apples = bananas.
So if you think of the apples as x, and the banans as y. 2x = 5y, x = 5/2. As the ratio of apples to bananas is 5/2.
I hope this helps.

@@zenmarais8425 dont u just times both sides by 7 to get 14?

[@bobmarlis446]

how comes you switch the numbers around on question 21

[@Wngman-uz8qt]

He showed an example why by subbing in the numbers. If you need 4 lots of C to equal 3 lots of D then there has to be more in each ´bit' of D

[@manlapyt3679]

@@Wngman-uz8qt thx i had the same question

[@g.o.a.t.energy5964]

for q19, why didnt you multiply x squared by 6 and p squared and x squared by 6

[@manlapyt3679]

In question 19 can you use (n-2)x180 in both and then take away the small one from the big one ? Or that will not work

[@thrilite3981]

that works as well you can doo that so you get (6-2)x180 which is 720 which is the sum of interior angles, then you divide by 6 to get 120 so each side is 120, then you divide that by two to get 60 to find out a triangle of that like he did

[@honkahonkanoise]

i don't understand why on question 18 you use l(squared) three times?? why isn't it just the square root of two l(squared)? please could someone get back to me on this thanks lol

[@sanmus100]

Because d^2 = 2l^2, and AH is equal to square root of d^2 + l^2
