Henry Park Math paper.

Part I Q27 and Part II Q9 were missing some important informations.

Is this the question: Paper 1 Q27 that you wrote as \"Part I Q27\" ->
http://i54.tinypic.com/2klz7k.png\">
The smaller angle given is 74 degree while the bigger angle given should be 145 degree. Angle a is the one at the tip of the isosceles triangle.
145 degree - 74 degree = 71 degree
(180-71-71) degree
= 38 degree

As for Part II Q9, is this the question on the flow rate of tap A and tap B together with a graph?
If yes, suggested solution as below:

Tap A
6 min -> (30-24) litres = 6 litres
1 min -> 1 litre
3 min -> 3 litres

Tap A + Tap B
(9-6) min -> (24-9) litres
3 min -> 15 litres

Tap B
3 min -> 15 litres - 3 litres = 12 litres
1 min -> 4 litres

In one minute, 4 litres of water were drained out from Tap B.

If not, which question is \"Part II Q9\" in 2011 Henry Park Pri Sch P6 Prelim that you had mentioned?

Sorry for Part II what I meant was question 12. The angles x and y were not labeled.
Just like the question above where angle a was not labeled.

Tinkerbelle:

For Q43B, the answer in the answer key is Material A. It reflected the most light.
However, DD's answer is Material C. It reflected light at the furthest distance from the light source. So....:scratchhead: Any other input?

My ds also put C.

Answer provided for 38c is wrong.

Question 42 itself is weird. Answered provided is correct according to the question. But the device really does not make any sense in the first place.

Based on given answers provided by Jeremy, angle x and angle y should be labelled as the above picture.
Angle x = 75 degree and Angle y = 120 degree.

BTW, how was your DS's Nan Hua Pri Sch's 2011 P6 Prelim Maths paper? Easy or tough? The one that vlim's DS took (Rosyth Sch) was not easy.Thks for your feedback.

sorry I don’t have a scanner. But can anyone who has the Henry Park 2011 Prelim Paper 2 Question 10 let me know which is the original shaded part of the figure? There is already some shading done by the student which is also black (from Jeremy’s papers). I can’t tell which is the original shading mentioned in the question.


Figure is a square with a circle inside touching the 4 sides of the square.

Q10 - Her answer is 2 but answer key was 3!

Hi Brenda10,

All given answers for MCQs (2011 Congfu School P6 CA2 Science) are correct.
For Q10, pls ask your DD to read the question again. It says \"An experiment was set up....... in the diagram below\" means at the start of the experiment, everything was shown as per set up in the diagram itself.So, the correct answer should be option (3) - W, Y and Z only.

Thks.

Hi Vanilla Cake

Thank you for your input and I will let her know!

Hi mummies/daddies,

Yet to know what will be the reporting time (for DD school) as that day only P6 students need to report to school!

That' wish all the P6 DD/DS good luck! :rahrah: :rahrah: :rahrah:
