Edexcel gcse maths exam 2day?

Question

discuss answers? did newun get 9720 for the depreciation question, and 7.07% for the percentage increase one?x

Answer 1

I dnt think you rounded nething incorrectly i also got 7.06. I got 7680. 4 da density and volume questions wat did every 1 get. I got something lyke 503 and then for mass 302

Answer 2

It can be 3 and 15 aswell, just checked it out and there both right. The highest common factor of 3 and 15 is 3 and there lcm is 45.

Answer 3

i got the 7.07% one but not the 9720, i think i put 7680 for the deprication Q

Answer 4

yeah i got 7680 for that ques and 7.07%...but they were the easy ones. The answer is 58 ^ because there ALTERNATE angles (remember that one). I got 85.5 for the cosine aswell and 1.4, 5 for the last one...i had to use trial and error for that cos i had no idea :S. I made a mistake on that HCF, LCM question...i put 3 and 15 but its actually 3 and 45 i found out :(

Answer 5

I got 7.06% for the percentage increase - may have rounded incorrectly

I got £7680 for the depreciation one

Overall i 4t that test was reli easy.

Wot did every1 get 4 the last question - dat took a bit of thinking about - i got a = 5, k = 1.4

Also i think the quadratic equation question was 1.22 or -3.55

There may have been anova quadratic equation question

tho, but i think that was definately an answer for a quadratic equation question.

Wot did people get for q24) You had to find an angle using the cosine rule, then rearranging it. I got 85.5!

Good luck with the rest of ur exams!!!

-------------EDIT--------------

LAUZ!!!!

58 was the correct answer

I think it was either to do with corresponding angles or "z" angles. I put corresponding angles are the same. It may have been alternate angles. Any1 got any thoughts!

-------------EDIT------------

ROB S!!!!

3 and 15 doesn't work

The highest coomon factor is 3

But the lowest common multiple is 30.

I put 9 and 15 (ROXY wots wrong with 9 and 15)

I also think 3 and 45 is correct

Answer 6

Yeah I got 7.07 or something like that for the percentage one. I don't even remember what the depreciation question was!

For the quadratic equation did anyone else got something like 0.5 and -2.8?

Answer 7

It was hard!

I got 7.07% and £7680 or sumink like that for the depriation one.. And i put 9 and 15 for the other question..

Oh also I would like to ask, you know on the upper bound question, did u have to put the highest number on top and divide it by the lower number, cos thats what i did, Im not sure if its right, cos it may be the other way round..??

Answer 8

yeah i got 7% cant remember the other tho.

it was really hard

Answer 9

for the edexcel maths exam for some of the answers i put:

5x + 60 = 360, what this right? or was it 5x=300? or can it be either?

and for the upper bound it was upper bound divided by lower bound? is that right?

and the isometric projection was i think a 3d house with 2  triangles at the top? am i right?

also the triangle question, that was tan wasn't it? it wasn't sin was it?

Answer 10

Yeh I got the 7.07% but got 7680 for the other. How did you find the last question??? I didn't have a clue what to do and was just fiddling around with it in the last minutes and came up with 5 and 1.4, which worked. It made my day!! What did you get for the angle one, where they was a 58 degree and 65 one I think and then it was give a reason for what y was. I put 58, but i couldn't really explain why!!!

Im sure that you have done fine!!! Good luck with the rest of your exams!!
