I don't think that I will finish this but I have got a query


Section 19 q8

I asked my student grandson for help ( he says he knows everything & I think he does!) and he says that there are 2 possible answers

"Point P can be in two places:
Either (8,3) that's two units from B and four units from A
Or (16,3) that's 12 units from A and 6 from B"

Can anyone clarify please?

[smouse]

I agree I think there are 2 answers to this but for some reason decided to just put one 8.3

[jared25]

I've gone for 8.3 as well

It is not the only question in that section that does not have a unique solution. There are three different possible answers to the question about the teacher with n cards.

Thank you smouse, jared25 & pulse876. Sorry for the delay in replying - I headed off to bed after posting it - Hubby in hospital and I had had a long day - I didn't understand the question - never mind the answer so thanks go to you all and Ben of course (again)

This is the answer that he gave me for the teacher question

Bearing in mind every number is the square number of something( but we won�t get
into that I�ll assume the question asks for the squares of integers only)(and
yes I do enjoy being pedantic)
n=25 25 cards, 25 is 5� and so the cards have the squares of 1 2 3 4 and 5 25
cards 5 square numbers and so one fifth of the cards are square numbers.

[pulse876]

I agree that 25 is a possible answer to the card question. But the teacher could also have 15 cards (which would contain the three square numbers 1, 4 and 9) or 20 cards (which would contain the four square numbers 1, 4, 9 and 16). The question doesn't specify that n itself must be a square number, only effectively that it must be divisible by five.

no longer got the sheet but dont think that quite fits

[pulse876]

granny g - in the same section did you or he get an answer to the question requiring you to insert mathematical sign(s) to make the sum correct?

If so, did you/he:
(a) use different mathematical signs in different gaps (which is relatively easy to solve), or
(b) use the same mathematical sign in each of the gaps (which a strict reading of the question would suggest is required) which is far more difficult and has me stumped.

[smouse]

I know youre not asking me lol

but I put
divide minus plus minus
and again dont have question any more

[pulse876]

smouse - I've no problem with you answering, especially since you seem to be winning most of the quizzes you've been entering this year(!) (congrats).

Yes I'm guessing that /, -, +, - (or /, +, -, -) is the expected answer in which case the question could be better worded.

Hi smouse and pulse876 just quickly logged on as of fto the hospital - my husband had his gallbladder out yesterday and they couldn't do it 'keyhole'

I've put divide minus times divide

[smouse]

I think a lot of the questions werent clear - certainly wont be winning this win lol

[granny grump]

You never know smouse - you seem to be on a roll. I've just had my second prize for the Retford Lions Quiz delivered - nice bottle of Bushmills. One of the Lions has a daughter who lives near by so it arrived safe and sound. It will be a nice welcome home pressie for my husband.
