AQA GCSE Maths Linear B UNOFFICIAL MARKSCHEME Calculator Higher

Thank you!


Posted from TSR Mobile

I will try and remember as many as possible (marks available are in the square brackets). Also, my answers might not be right - please feel free to point out any mistakes

These are the ones that I can (I think) remember the question numbers for:

1) Multiply all of the values by 20/8 (or 2.5) to get:
187.5g
125g
100g
5 egg yolks [3]
2) a) The total price before discount was 730 + 420 or something like that, which was £1150. Multiply that by 0.85 to get £977.50 so yes, she has enough[5]
b) 800 pounds is 800x1.25 = 1000 Euros. He spent 895, so has 1000 - 895 = 105 Euros left
When he reconverts back, £1 is 1.4 Euros so £75 is 105 Euros
The answer I think was £75 [4]
10) a) Lowest score was 5, highest score was 30, median was 18, lower quartile was 14 and upper quartile was 26, and then draw the box plot from that I think [4]
b) Jack scored more on average because he had a higher median (I think it was 21)
The amount of points Jack scored was more consistent because his interquartile range was smaller (I think his was 9 and the other one was 12) [2]
24) I think it was -0.78 and -2.55 [6]
25) I think there were quite a few different methods but I think the answer was no because the tent is 1.86 m tall. This is what I did:
Volume is 8 and length is 4 so area of triangle is 2
It's equilateral so all sides equal and all angles equal (60 degrees)
I used absinC/2 and let the sides be x to get that the area is x^2/4 multiplied by root 3 and set that equal to two, so then x^2 multiplied by root 3 is 8 and then x^2 is 8/root 3 and then x is root(8/root3) which was like 2.149...
I then did that the area is also given by base x height /2 and let the height be h so that xh/2 is the area and set that equal to 2 so xh is 4 and then h is 4/x to get 1.86 and no, he is too tall [5]

I don't know the question numbers for these, but I have some answers:

The Ship question was 90km (I think you had to use pythagoras or something like that) [5]
I think the circle theorem one was 71 degrees [2]
The question about the mean:
I think the one you had to circle was 15 to 25 [1] and the mean was 21[4]
The probability was 2/15 [3]
The factorisation was (7c+d)(7c-d) [2]
The simplify was something like x/2x+5 [3]
The one with completing the square and finding a and b I think was 5 for a and 18 for b [2]
The one for loaves of bread I think was 78, 39 and 13 [3]
The one for how long it takes for the tank to empty was 1 hour (45 litres divided by 0.75 litres per minute which is 60 minutes or an hour) [4]
The cosine rule one I think was something like 132.7 degrees [3]
The stratified one was something like 13, 19, 11 and 8 and you had to round one of them down to give it to 50 but I'm not sure [3]
The histogram frequency densities I think were 5, 10, 9 and 2.4 and then draw the histogram [4]
The thing about nails and screws I think you had to find the bounds for 1 packet and then multiply by four and six to show that they both could take the same value. I think maybe also subbing in numbers to see if they are the same might be right but I'm not sure [3]
The area of one shaded rectangle I think was 180 [5]
The trapezium with x and y I think was x is 12 and y is 20 [5]
The perimeter was something like 47cm [3]
The volume of the cylinder I think was 1696 [3]
The volume of the similar shape I think was 2734 [3]
There was the question where you had to draw the graph y = x^3 - 2 or something like that [2]
I think the equation of the straight line going through (0,4) was y = 5x+4 [2]
I think the original price of the car was £19500 or something like that [3]
The question about the first three terms I think was 4,2,0 [2]
The question about what the first term was, I think was 10 [3]
The question about Fahrenheit I think was 82.4 degrees F which had to be rounded to the nearest whole number so 82 [3]

I hope that this is helpful, but I'm not entirely sure about all the answers, so please tell me if I'm wrong!

For the trapezium one I got x = 12 and y = 16?

Maybe I'm wrong for that question. Thanks for pointing that out because I realised for my answer that I originally put (which might be wrong), I put x is 12 and y is 20 but I think y is 12 and x is 20

I thought it was something like 2x+y+128 = 180 and x+5y+100 = 180
So x + 5y = 80 so x = 80 - 5y and then 2(80-5y) + y + 128 = 180
So 160 - 10y + y + 128 = 180
So 288 - 9y = 180
So -9y = -108
So y = 12 and x = 80 - 5(12) = 80-60 = 20

But I'm not sure. It could be x = 12 and y = 16.

Hope I could help

Ooo !! Damn that may be right


I rearranged to and simplified leaving me with
x + 2y = 44
Then did trial an error

12 + 2 X 16 = 44

So x is 12 and y is 16

But I'm probably wrong ahahah

Thanks for this. I cant see much wrong with it.

Hmmm, for the trapezium one I got x=22 and y=11 (or the other way around), but this is presuming that all angles in a trapezium add up to 360 degrees. I even checked it and it was right. Where have I gone wrong??

What did people get for the tent question

I put different numbers for x and y than you lol and I checked my solution and it worked?? super confused as well

That was what I put as well, since working it out those 2 values fit x & y. Hope its correct! When I get the chance, ill go over the paper with my maths teacher, probably on monday. More exams tomorrow
