# AQA Maths 2017 Unit 1 Higher Tier *UNOFFICIAL* MARKSCHEME Watch

Announcements

*I know there has been 29 questions in this paper, so i am asking you to help me finish this. That's all I got so far*

**TOTAL MARKS = 80**(as i missed a few questions and am not sure of the marks per question, the total marks in this

*mark scheme is 73. As questions will be added, I will try to figure out the gap and make it as accurate as possible!)*

**UNOFFICIAL**OK, So i was reviewing the official thread and I would like other people to have the chance to see a better designed unofficial mark scheme for the AQA Maths - Unit 1 (Higher) 2017 paper and there it is...

***NOTE* - I am not sure of the question numbers, but the order of the questions is pretty much correct. Please do reply if you have any comments or if you want to add or correct the mark scheme**The mark scheme is built from replies in the official thread and it is partially credited for the answers here.

**Question 1: Simplify**

**2**

^{3}

**x 2**

^{5}

**[1 marks]**Answer:

*2*

^{8}

**Question 2: Congruent triangles**

**[1 marks]**Answer: ASA (Angle-Side-Angle)

**Question 3: Which of the given sequences is a geometric sequence?**

**[1 marks]**Answer: third answer -

*2,6,18,54,x*(can't fully remember)

**Question 4: The ratio of**

**a:b****is**

**3:4****; How would you represent b in terms of a?**

**[1 marks]**Answer: b is 3/4 of a (fourth answer)

**Question 5: Factorise and simplify 36**

**[2 marks]**Answer: 2

**Question 6(a): What is the gradient of the line between the points (-2,-5) and (-4,-9)?**

**[2 marks]**Answer: The gradient is -2.

Reason:

__-5 - (-9)__=

__-5 + 9__=

__4__= 2

-2 - (-4) = -2 + 4 = 2

**Question 6(b): Is the line going through the point (601,-301)?**

**[1 marks]**Answer: Yes.

**Question 7: Is reflection the only single transformation that can be used to make rectangle A fit rectangle B?**

**[1 marks]**Answer: No, translation can also be used.

**Question 8: You are given this equation: 8x km/h = 5y mph. Express y in terms of x.**

**[2 marks]**Answer: y = x/1.6

**Question 9: Write six million five thousand and two hundred in standard form.**

**[2 marks]**Answer: 6.0052 x 10

^{6}

**Question 10: What is the cheapest way to buy 8 bottles? You may split it between the three shops.**

**[4 marks]**Shop A: Buy 1; Get 2 for half the price

Shop B: Buy 2; Get 3 for half the price

Shop C: Get 30% off for each bottle.

The Initial price is the same between the shop and is up to your decision (NOT STATED IN THE QUESTION)

Answer: 6 bottles from shop A (2 x 3 bottles) and 2 bottles from shop C

**Question 11: A circle has been fitted to a square with the area of 64cm**

^{2}

**; What is the area of the circle in terms of pi?**

**[3 marks]**Answer: 16pi

Reason:

area of 64cm

^{2}means the square has sides of 8 cm - the diameter of the circle.

Area of circle - pi x r

^{2}= pi x 4

^{2}= pi x 16 = 16pi

**Question 12: Vectors (what was the question?)**

**[1 marks]**Answer: Second option (what was it?)

**Question 13: Solve the simultaneous equation: (2x+y=18) and (x-y=6).**

**[4 marks]**Answer: x=8, y=2

Reason:

2x+y=18

2x-2y=12 (double this)

then substract the second from the first equation.

3y = 6 therefore y=2

Apply the y in any equation:

2x + 2 = 18

2x = 16

x = 8

**Question 14: Cumulative frequency - what was the minimum marks for the top 20%?**

**[4 marks]**Answer: As its an estimate, it could vary between 70 to 80.

**Question 15: Acceleration (what was it?)**

**[2 marks]**Answer: 6 seconds

**Question 16: Distance (what was it?)**

**[2 marks]**Answer: 300m

**Question 17(a): True / False question (remind me please?)**

**[3 marks]**Answer: False, False, True

**Question 17(b): True / False question (remind me please?)**

**[3 marks]**Answer: True, True, False

**Question 18: What is the diameter of the circle x**

^{2}

**+ y**

^{2}

**= 64?**

**[3 marks]**Answer: 16

**Question 19: Calculate the tangent to the circle equation in the form of y = mx + c**

**[3 marks]**Answer: y= 1/4 x + 4 & 1/4

**Question 20: What will be the total price for the tickets?**

**[4 marks]**Answer: £90.64

Reason:

price before any fees: £80

add 10% booking fee: £80 + £8 = £88

add another 3%: £88 x 1.03 = £90.64

**Question 21: How many people are there in the office?**

**[4 marks]**Answer: 288

Reason:

m = 2f (there are twice more female then male)

1/4 female wear glasses; 3/8 male wear glasses.

there are x people who wear glasses.

*forgot what i did then sorry...*

**Question 22: In order to fit triangle A in triangle B, two transformations where used. The first one was rotation of 90° from E.What was the second transformation?**

**[3 marks]**Answer: Enlargement with a s.f. of -2 from (-1,0)

**Question 23: Expand and simplify (x-4)(2x+3y)**

^{2}

**[4 marks]**Answer:4x

^{3}+ 12x

^{2}y + 9xy

^{2}- 16x

^{2}- 48xy - 36y

^{2 }

Reason:

(x-4)(2x+3y)(2x+3y)

First step: expand this - (2x+3y)(2x+3y)

(2x+3y)(2x+3y)

4x

^{2}+ 6xy + 6xy + 9y

^{2}

Then simplify:

4x

^{2}+ 12xy + 9y

^{2}

Now expand this - (x-4)(4x

^{2}+ 12xy + 9y

^{2})

(x - 4)(4x

^{2}+ 12xy + 9y

^{2})

4x

^{3}+ 12x

^{2}y + 9xy

^{2}- 16x

^{2}- 48xy - 36y

^{2}

**Question 24(a): Write root(12.25) as an improper fraction**

**[2 marks]**Answer: 7/2 ( root(49/4) )

**Question 24(b): Write cubic_root(16) as power of 2 (2^x)**

**[2 marks]**Answer: 2

^{(4/3)}

**Question 28: What is the volume of the water in terms of pi?**

**[4 marks]**Answer: 117pi

**Question 29: Simplify this (sin and tan question)**

**[4 marks]**Answer: ( root(6) - root(3) ) / 12

*NOTE* - I am not sure of the question numbers, but the order of the questions is pretty much correct. Please do reply if you have any comments or if you want to add or correct the markscheme

Answer: The gradient is 2.

Reason:

-2 - (-4) = -2 + 4 = 2

Answer: Yes.

Answer: No, translation can also be used.

Answer: y = 1.6x

Answer: 6.0052 x 10^6

Shop A: Buy 1; Get 2 for half the price

Shop B: Buy 2; Get 3 for half the price

Shop C: Get 30% off for each bottle.

The Initial price is the same between the shop and is up to your decision (NOT STATED IN THE QUESTION)

Answer: 6 bottles from shop A (2 x 3 bottles) and 2 bottles from shop C

Answer: 16pi

Reason:

area of 64cm^2 means the square has sides of 8 cm - the diameter of the circle.

Area of circle - pi x r^2 = pi x 4^2 = pi x 16 = 16pi

Answer: Second option (what was it?)

Answer: x=8, y=2

Reason:

2x+y=18

2x-2y=12 (double this)

then substract the second from the first equation.

3y = 6 therefore y=2

Apply the y in any equation:

2x + 2 = 18

2x = 16

x = 8

Answer: 53 marks

Answer: 6 seconds

Answer: 300m

Answer: False, False, True

Answer: True, True, False

Answer: 16

Answer: y= 1/4 x + 4 & 1/4

Answer: £94.64

Reason:

price before any fees: £80

add 10% booking fee: £80 + £8 = £88

add another 3%: £88 x 1.03 = £90.64

Answer: 288

Reason:

m = 2f (there are twice more female then male)

1/4 female wear glasses; 3/8 male wear glasses.

I'm pretty sure the ones you called 22 and 23 are actually 28 and 29.

Also, there's a typo on 21- you should have wrote £90. instead of £94.

Heyy, I was wondering if anyone had an idea of what the grade boundaries will be like. I've heard rumours that about 33% will be a pass (and I know this is wayy too low). What are you guys thinking?

There was one question about the office workers (sorry I don't know the exact question) but it referred to there being twice as many females as males, 1/4 of the females wearing glasses and 3/8 of the males wearing glasses. I think there was a total of 84 (or something along those lines) workers wearing glasses and it asked you to find out how many workers there were altogether.
