now that is great 100 post debating maths and grammer what and no padding from the drivel team:oo:

[SPIRIT]

sorry Wongo you padded up

[ss_11000]

i think i just wasted ten minutes or so reading this...twas quite funny thou.
i got 350 as the answer in 30 seconds or so. i know what you guys mean when you say ppl dont read the question because i do it alot ( i only get 90% ish instead of 100% cos i misread or dont read the question and assume i know what i have to do ).

maths is truly to easy:) ( most of the time - i hate factorising:( lol )

cheers

BTW congrats wongo on ur 100% hsc mark...tis what i aim for in 4 unit maths in two yrs time.

Doing exams is a bit like woodwork
Exams - read the question twice and answer once
Woodwork - measure twice and cut once

Mr C: I'm just glad they're not building my house :U


So am I

Would you not get a bigger house? :?

[Wood Borer]

Possibly you would have got a house with a floor area of 350 but an invoice for an area of 500.

Of course if you were mathematically challenged, you would be quite happy with the house and the bill. Ignorance is bliss.:D

I would be happy if it was the other way round but of course the rooms might be the wrong shapes

[SPIRIT]

you get a new maths question tomorrow:D

[MurrayD99]

you get a new maths question tomorrow:D

You'll compromise the drivel channel. What'll we do?:D

[SPIRIT]

good point you cliff and the others should be able to help with my kids homework:D :U

[Wongo]

I am not available tomorrow. I have more important thing to discuss in another forum. :D

[Gra]

Give us a kiss and l will see

:kiss1:


now that is great 100 post debating maths and grammer what and no padding from the drivel team:oo:

are you trying to say we are math debating:U:U:U

[ian]

question 1-D
A rectangle has a perimeter of 90cm .the length of the rectangle is 25 cm
more than the width

find the of sq cm in the area of the rectangle

you have 6 Minutes:roll:width of rectangle = (90 – 2 x 25) /4 = 10 cm
Rectangle is thus 35cm long and 10 cm wide
check the sums — (length + width) x 2 = (35 + 10) x 2 = 90 checks

area = 35 x 10 = 350 cm squared

Ian, where were you when we needed you.:p

If you took a survey today, people would say the earth was almost spherical. Could the majority from either era prove their answers? I suggest not. Those from Copernious's time couldn't, but it's straight forward.

A sphere casts a cylindrical shadow no matter what direction it is illuminated from. This is the only shape that does.
During a lunar eclipse the earth's shadow as it passes across the moon is always round. Therefore the earth is a sphere.

AND if you can measure distances along a meridian you can work out the earth's approximate size.

In the early days scientists went to still lakes and measured how much "dip" there was from one end of the lake to the other by measuring how far out of sight a graduated object fell. Assuming light travelled in a straight line they were able to calculate the radius of the earth.

This method of course had several problems:

1: It is possible that the atmosphere near the lake had different densities, temperatures etc that could cause refraction (bending of light).

2: It didn't prove the radius of earth was reasonably constant so unless multiple measurements were made in different directions in many places, this method only suggested that the earth's surface was curved.

People who state that they have seen "pictures" of the earth from space could be victims of a photography hoax. For example some Science Fiction pictures seem more realistic than current and past photos from space.

Personally I believe the earth is almost spherical, assuming that it is certainly helped me navigate using a sextant and compass. Unless of course I stuffed up the calculations and by pure chance happened to return.:D

Could I prove it was spherical? Not conclusively. Like many others on this forum I have studied University Maths however I wouldn't bet my LNs that I could prove the earth was round.

By prove I mean a mathematical proof and not an argument that convinces others that I am right.

[silentC]

A sphere casts a cylindrical shadow no matter what direction it is illuminated from. This is the only shape that does.
During a lunar eclipse the earth's shadow as it passes across the moon is always round. Therefore the earth is a sphere.
That assumes that the moon is lit by the sun and not from some other source, such as radioactive cheese.

[MurrayD99]

It it really is round, wouldn't it make sense to fire the rockets sideways over the Atlantic so the go downhill rather than straight up at the moon. Burn a lot less fuel, surely. Mr C, I never thought of the hot cheese possibility. Is that widely known?

[Wood Borer]

That assumes that the moon is lit by the sun and not from some other source, such as radioactive cheese.


But wouldn't radioactive cheese cause radio communications problems when we have a full moon? Probably would be called Moon spots.

[Wongo]

The earth is round. Trust me, I've been there.

Q:ok readers of the breaky Debate im going to now hijack this theard ,if l offend anybody sorry please say something,, asap.thanks

Q/
A/1 how should you teach kids
about universe,,,,,,

when dealing with a 11yo do a f=+t and say l just created a universe and now they call me GOD ,,,,,,,,,,,,,,,,,,,,,,,,a 11yo boy finds that funny13 yo girl finds that grossssss and come back with your no God you just stink:oo:
why not why can't l be creating small universe using a theorem that ???? slides down hill !there is always something never nothing its just to small or to big to see

[silentC]

I don't know what you are eating for breakfast but I'm sure it's bad for your health... :p

[SPIRIT]

are but good for the mind

[Bob38S]

are but good for the mind


Are you telling us that you are sitting on your mind? :o

I though that this was the place where most of our pollies had their heads up. :2tsup:

[Chesand]

Spirit
A good way to get the kids going is to ask them what happens to the holes in dry biscuits when they eat them. As the discussion goes on you can then ask how they manage if they have a stomach full of holes.
It caused consternation here a few years ago - one daughter even asked her science teacher.

[SPIRIT]

its easy to see some people can only answer maths question :rolleyes:

[MurrayD99]

Was there not to be another question this day? Nah, too late.

[SPIRIT]

Was there not to be another question this day? Nah, too late.
ok she took her work book to school so my memery is not what it use to be

mary spends 3.00$ ,the roll is 30cents more than the milk the milk is 60cents more than the fruit,how much is the roll

[silentC]

How long was the roll?

[MurrayD99]

$1.40, he ventured, anxiously hoping he would not be required to stay late on a Friday afternoon.

[Gra]

I dunno, but I can bet she got charged three withdrawal fees:q:U

[SPIRIT]

what the roll is 1.40$ how did you get that

[SPIRIT]

How long was the roll?READ THE QUESTION see that saying is cool:2tsup:

[MurrayD99]

what the roll is 1.40$ how did you get that

3.00 = (M + 30) + (M - 60) + M

3M = 3.30.....

Roll is 12'6"

[Wongo]

mary spends 3.00$ ,the roll is 30cents
more than the milk the milk is 60cents more than the fruit,how much is the roll
Hang on, you said the roll is 30 cents.
How can it be more than the milk when the milk is 60 cents??
Also, you forgot to put "more than.." in a new line. :D

My answer: 30 cents. :D

[MurrayD99]

Hang on, you said the roll is 30 cents.
How can it be more than the milk when the milk is 60 cents??

My answer: 30 cents. :D


Yeah, well, you might well be correct. Sir, can I leave now please. Been a long week and fuel just went up 2c:(( .

[SPIRIT]

Hang on, you said the roll is 30 cents.
How can it be more than the milk when the milk is 60 cents??
Also, you forgot to put "more than.." in a new line. :D

My answer: 30 cents. :D
what the roll cost 30cents :?

[Wongo]

Yes. 30c, no more no less.

Trust me.

[SPIRIT]

Hang on, you said the roll is 30 cents.
How can it be more than the milk when the milk is 60 cents??
Also, you forgot to put "more than.." in a new line. :D

My answer: 30 cents. :Dl never did say that

[Wongo]

and the milk is 60c
that makes the fruit 3 - 0.3 - 0.6 = $2.10

[HappyHammer]

that
Did so..

HH.

[SPIRIT]

how much was the friut

[SPIRIT]

Did so..

HH.did not

[Wongo]

l never did say that

Well that’s my interpretation of the question.:p

[SPIRIT]

Well that’s my interpretation of the question.:pMAYBE but l did't say it

[silentC]

Is this the right room for an argument?

[SPIRIT]

hay wongo maths the only questions you answer

[Wongo]

ok she took her work book to school so my memery is not what it use to be

mary spends 3.00$ ,the roll is 30cents more than the milk the milk is 60cents more than the fruit,how much is the roll


milk = 0.6 + fruit
roll = 0.3 + milk = 0.3 + 0.6 + fruit

fruit + milk + roll = 3

3*fruit + 1.5 = 3

fruit = $0.5

therefore milk = $1.1 and roll = $1.4

[RobP]

$1.40, he ventured, anxiously hoping he would not be required to stay late on a Friday afternoon.

I agree.
Let cost of fruit = x
Milk is x + 60
Roll is x + 60 + 30
Total cost of lunch is x + x + x + 60 + 60 + 30 = 300
3x + 150 = 300
3x = 300 - 150 = 150
x = 50
So Roll is 50 + 60 + 30 = 140 or $1.40

EDIT: Damn Wongo, you type faster than me.

[SPIRIT]

Is this the right room for an argument?yep that will be a greenie thanks

[Gra]

hay wongo maths the only questions you answer

Nah he answers Excel questions too, as long as I don't beat him to it:q

[SPIRIT]

milk = 0.6 + fruit
roll = 0.3 + milk = 0.3 + 0.6 + fruit

fruit + milk + roll = 3

3*fruit + 1.5 = 3

fruit = $0.5

therefore milk = $1.1 and roll = $1.4told you l didn't say it

[SPIRIT]

Nah he answers Excel questions too, as long as I don't beat him to it:qdo you think he stores his pens in his shirt pocket :U

[Gra]

do you think he stores his pens in his shirt pocket :U

Cant say much, I store my pens in my pocket when at work........

[SPIRIT]

Cant say much, I store my pens in my pocket when at work........
:no: just sad

[Wongo]

do you think he stores his pens in his shirt pocket :U


Yes and the ink leaks too.

[journeyman Mick]

l never did say that

Yes you did:


mary spends 3.00$ ,the roll is 30cents
more than the milk the milk is 60cents more than the fruit,how much is the roll

It's all how you (mis)read the question.:U

[Wongo]

Thats me. :D

[ian]

mary spends 3.00$ ,
the roll is 30cents more than the milk the milk is 60cents more than the fruit, how much is the rollhere goes
milk = fruit + 60¢
roll = milk + 30¢
therefor roll = (fruit + 60) + 30 = fruit + 90¢

Mary spent 300¢, she bought roll + milk + fruit
substitute terms
(fruit + 90) + (fruit + 60) + fruit = 300
3 x fruit + 150 = 300
3 x fruit = 150, so fruit = 50¢
so the roll was 50 + 90 = $1.40 and the milk = $1.10

check roll + milk + fruit = $1.40 + $1.10+ $0.50 = $3.00



do I get the piece fruit??
