Fairy Best Freinds:

Jerry bought four times as many pencils as notebooks and spent a total of $21.60. He spent $2.40 more on the notebooks than the pencils. Given that a notebook costs $3.20 more than a pencil, find the cost of a pencil.


Thank you.

Hi

You may use MD for this question.

Sorry no time to draw now, but there are some examples in previous posts.

NB ----- 12
Pencils ----- 9.6

9.6/4 ------ 2.4

12 – 2.4 ----- 9.6

A notebook costs $3.20 more than a pencil.
9.6/3.2 ----- 3

There are 3 NB, therefore 12 pencils.

Cost per pencil ----- 9.6/12 ------ 80 cents.

Best wishes

How did you find out that it is 12 NBs..sorry quite blur, pls help!

Q41b.
Describe one action michael has to carry out consistently thruout the expereiment in order to get reliable results?

DS says
timing.

ans.sheet says place the car from top of the ramp.

Q43b
My ds answer is
chemical potential energy -electrical energy - kinetic energy-sound energy.

alhtough ans.sheet is
kinetic energy-electrical energy - kinetic energy-sound energy.

Hi,

All the answers provided by the worksheet are correct.

Q32b. Question asks whether the same type of types should be used, so there is no need to talk about the number and other variables.

Q41b. Timing is the results, so cannot be kept constant.

Q43b. Point A - Kinetic energy, as the point moves to make contact to close the circuit. [Question does not ask for the source of energy which is chemical potential energy]

You are my saviour ::thankyou: yet again..

Thank you Kiddo.


While most people look forward to the weekends, I am glad to be back at work. DH has taken the day off and is at the golf course now. I have been having dream filled sleep lately. No idea what the dreams were really about but in it, I was screaming at DH and I wake up agitated and at times in tears.

DH seems to be avoiding me since I broached the subject of him seeking counselling. Dunno if he feels rejected by me as I told him I am not equipped to help him overcome his depression.

I know I should talk to him further about counselling. But for now, I am also avoiding that. I dun think I can handle it now.

The saddest thing is I think the tension is rubbing off on the kids. DD woke up all emotional and unhappy this morning. She has also been quieter and withdrawn over the weekend, sticking close to me all the time.
