HI ALL, I've drawn up the logo question and written my answers from memory. do check if it's correct. thank you

HEY GUYS, CHECK YOUR MATHS PAPER 2 ANSWERS HERE : https://justpastpapers.com/0580_s16_ms_22/

Hi thanx a lot, btw u hav any idea how d pictures wer taken?

I am trying to make a mark scheme for the exam we just had. These are the answers I remember I wote. Please correct me when I am wrong and contribute.

Question 1) 12 35, 788 km/h, price of economy ticket
$800, 1433.6 km travelled in car, $186.37 for fuel

Question 2) (c) x = 1 2/3
(d) x = -2/3

Question 3) (d) enlargement by scale factor 3, centre of enlargement (0,0)

Probability question
a) 0.05
last one) 0.243

Graph question
3 values of x ~ -2.1 0.4 2.1
values of x for f(x)+2= -5x
0.4 and 0.55?
values for x in quadratic equation
3.17

Logo question
Proof: 360-210= 150
180-150= 30
30÷2 (isosceles triangle) is 15
Length of line 15.5
Angle ABC 25.2

Cuboid question
Area of the cuboid 9900 cm²
conversion to m² 0.99

Last question (gradients and construction)
a) root of 360
b) 3x+1
c) 3x-5
d) y= -1/3x + 13/3 (with thanks to AbirHBK)

question 1 about the distance travelled is wrong its 1130 and the fuel is wrong as well the angle ABC is not 25.2 it involved since rule if i remember i got about 24.9 or something like that.

For question 1, it could also be your value depending on whether you consider insurance or not.Therefore fuel would vary as well. About angle ABC, I have heard many different answers, all around 25, so we are close on that. Thanks for responding, I will include what you mentioned

I think the cost of economy class ticket was $940. I did the paper thrice and each time it came out 940

Yeah.. but i dont think its realistic to get an answer with decimal places and if it was logic i think he would take the insurance since he is a in a new place and doesn't know the street and place well.About the 25.2 question how did you get it?? i used sine rule.

There were two questions relating to that topic, for the first airline the answer was 940, but for the second airline the answer was 800.

the time was 12:45 i think? i dont remember clearly but i think it was 12:45?
