# GCSE AQA Non calculator unofficial mark scheme watch

1. For question 17b, i understand that the answer is 2.2 but how do you actually find it, i wrote 1.5 carelessly because i thought you go to 5 on the y axis, go across and then down which led me to 1.5. Does anyone know an actual method to find it?

if that was the root5 question, you had to say that x was root5, so 2x^2 would be 10, and then you draw the line y=10 and see where it crossed the curve

Thanks so much, i would've really struggled if a question like that was to come up in the calculator paper without your help. Thanks ☺

No problem, good luck with the exam on Thursday - remember it's calculator so you can do loads of trial and error until you get an answer that seems reasonable

For the linear specification marked out of 70

1. £256.50
2. 750cm^3
3. 16cm
4a. 0.4 and 0.2
b. 200 150 100
c 0.125
5. 10cm
6a as average temperature goes up soup sales down
b 500
7. 4.5
8a 4 ( I got 2 )
b 1,2,3,4
9a w^2
b 12x^4y^5
c 6a^2b^4
10a 1.8 X 10^4
b 5 X 10^3
11. Enlarge 1/3 around (10,10) (I got -3)
12a 35
b 25
c A+D & B+C = 180
13a 12x^2+16x-3
b X=0.75 or -1
14. 8 cm
15 x= 5/y-3
16. X<7/9
17 a -2.7 or 2.7
b 2.2
18 9 - 4 root 3
19a y=1/X
b (0,1)
20. Substitute X as 2 and PI as 3 and both volumes are the same but PI is bigger 3.14 so the sphere volume would be bigger.

Not sure on 14, 16 and 17b but I think I got roughy 64
What are the topics roughly?
