a) prime number .... 2 or 5 (1 mark)

b) write down 3 squares that add to make 21 ... 16 + 4 + 1 = 21 (2 marks)

19) a) solve 8f + 19 = 15

so 8f = 15 - 19 so 8f = -4 so f = -4/8 = -1/2 or - 0.5 (2 marks)

b) solve 2c + 5 = c + 8

so 2c - c = 8 - 5 so c = 3 (2 marks)

20) paid £2000 per month, saves 6% each month, how long to save £480 ?

6% of 2000 = £120 so £480 / /£120 = 4 months (3 marks)

21) 4.5 kg oranges + 3kg of apples cost £3.87

2.5 kg oranges cost £1.40. How much does 1kg of apples cost ?

so if 2.5 kg of oranges cost £1.40, 1 kg cost £1.40 / 2.5 = £0.56

so 4.5 kg cost £0.56 x 4.5 which is £2.52

if 4.5 kg oranges + 3kg of apples cost £3.87 then 3 kg of apples costs

£3.87 - £2.52 = £1.35

so if 3kg of apples cost £1.35 1 kg cost £1.35 / 3 = £0.45

asks for answer is pence so answer is 45 pence (4 marks)

22) There's a table with chocolates

a) probability dark choc caramel .... 1/30 (1 mark)

b) probability of white chocolate .... 9/30 = 3/10 (2 marks)

c) dark choc is 0.35 milk choc is 0.17 so missing prob is 1 - 0.35 - 0.17 = 0.48 (2 marks)

23) Redlands sends x students, St Sams sends twice as many, Francis send 7 less than Redlands. Each students pays £15, total paid is £1155.

So Redland sends x, St Sams sends 2x and Francis sends x - 7

so total number of students is x + 2x + x - 7 = 4x- 7

total paid is 15 ( 4x - 7) = 60x - 105

This total = £1155 ..... so 60x - 105 = 1155 .... so 60x = 1155 + 105

so 60x = 1260 ... so x = 1260 / 60 = 21

so Redlands sends 21 students St Sams sends 42 and Francis send 14

24) loci question ... should have a straight line across from left to right, circle in bottom right had corner ... shaded in bit in bottom right ( 3 marks)

25) birthday cake ... 7 inch diameter .... 1 inch = 2.54 cm ... ribbon sold in 50cm length

so circumference of cake = pi x 7 = 21.99114858 inches

convert this to cm by multiiplying by 2.54 ... 21.99114858 x 2.54 = 55.85751738 cm

so no, 1 length of ribbon isn't long enough (4 marks)

26) rectangle ...length 30cm, width 20cm PLUS 2 diagonals

so use Pythag to calculate the length of the diagonals

20 squared + 30 squared = 1300 which you then need square root

so 1 diagonal = 36.05551275cm ...

so 2 diagonal, plus 2 widths, plus 2 lengths

(2 x 36.05551275) + (2 x 30) + (2 x 20) = 172.1110255 cm

asks to round to 1 decimal place so answer is 172.1 cm (4 marks)

so total number of students is x + 2x + x - 7 = 4x- 7

total paid is 15 ( 4x - 7) = 60x - 105

This total = £1155 ..... so 60x - 105 = 1155 .... so 60x = 1155 + 105

so 60x = 1260 ... so x = 1260 / 60 = 21

so Redlands sends 21 students St Sams sends 42 and Francis send 14

24) loci question ... should have a straight line across from left to right, circle in bottom right had corner ... shaded in bit in bottom right ( 3 marks)

15 / 105 * 100 = 14.28571429 = 14.3 to 1 dp (2 marks)

11) bar chart question about museum visitors

a) 300 adults visited in March

b) Total number of adults = 2050 Total number of children = 2150

so the difference is 2150 - 2050 = 100 (3 marks)

12) Electricity bill

units used 2968 - 2675 = 293 cost is 293 * 18p = 5274 pence = £52.74 (4 marks)

13) a) (i) 3 7 11 15 next term would be 19

(ii) why ....adding 4 each time (2 marks)

b) work out 11th term ... keep adding 4 answer 43 (1 mark)

c) is 79 in the sequence ? yes it is ... nth term is 4n-1 .... 4 x 20 - 1 = 79 (1 mark)

14) list of numbers .... in order

12 12 12 12 13 15 15 15 16 17 17 18

a) mode is 12 (1 mark)

b) range is 18 - 12 = 6 (2 marks)

c) median is 15 (2 marks)

d) mean is 174 / 12 = 14.5 (2 marks)

15) wants to cycle 70km each week ... convert all distances to metres then add

18.2 km = 18200m

14 km 250m = 14250m

20.5km = 20500m

12050m

total in metres = 65000m which is 65 km so no he doesn't cycle 70km (4 marks)

16) Survey of car colours ... suggest tally chart

Colour of car Tally Frequency (3 marks)

17) 6 buttons in a pack, 15 buttons in a box

buys d packets of buttons and f boxes of buttons ....

so formula for T in terms of d and f .... T = 6d = 15f (3 marks)

18) list of numbers 1 2 4 5 8 9 12 15 16

a) prime number .... 2 or 5 (1 mark)

b) write down 3 squares that add to make 21 ... 16 + 4 + 1 = 21 (2 marks)

19) a) solve 8f + 19 = 15

so 8f = 15 - 19 so 8f = -4 so f = -4/8 = -1/2 or - 0.5 (2 marks)

b) solve 2c + 5 = c + 8

so 2c - c = 8 - 5 so c = 3 (2 marks)

20) paid £2000 per month, saves 6% each month, how long to save £480 ?

6% of 2000 = £120 so £480 / /£120 = 4 months (3 marks)

21) 4.5 kg oranges + 3kg of apples cost £3.87

2.5 kg oranges cost £1.40. How much does 1kg of apples cost ?

so if 2.5 kg of oranges cost £1.40, 1 kg cost £1.40 / 2.5 = £0.56

so 4.5 kg cost £0.56 x 4.5 which is £2.52

if 4.5 kg oranges + 3kg of apples cost £3.87 then 3 kg of apples costs

£3.87 - £2.52 = £1.35

so if 3kg of apples cost £1.35 1 kg cost £1.35 / 3 = £0.45

asks for answer is pence so answer is 45 pence (4 marks)

22) There's a table with chocolates

a) probability dark choc caramel .... 1/30 (1 mark)

b) probability of white chocolate .... 9/30 = 1/10 (2 marks)

c) dark choc is 0.35 milk choc is 0.17 so missing prob is 1 - 0.35 - 0.17 = 0.48 (2 marks)

23) Redlands sends x students, St Sams sends twice as many, Francis send 7 less than Redlands. Each students pays £15, total paid is £1155.

So Redland sends x, St Sams sends 2x and Francis sends x - 7

so total number of students is x + 2x + x - 7 = 4x- 7

total paid is 15 ( 4x - 7) = 60x - 105

This total = £1155 ..... so 60x - 105 = 1155 .... so 60x = 1155 + 105

so 60x = 1260 ... so x = 1260 / 60 = 21

so Redlands sends 21 students St Sams sends 42 and Francis send 14

24) loci question ... should have a straight line across from left to right, circle in bottom right had corner ... shaded in bit in bottom right ( 3 marks)

25) birthday cake ... 7 inch diameter .... 1 inch = 2.54 cm ... ribbon sold in 50cm length

so circumference of cake = pi x 7 = 21.99114858 inches

convert this to cm by multiiplying by 2.54 ... 21.99114858 x 2.54 = 55.85751738 cm

so no, 1 length of ribbon isn't long enough

26) rectangle ...length 30cm, width 20cm PLUS 2 diagonals

so use Pythag to calculate the length of the diagonals

20 squared + 30 squared = 1300 which you then need square root

so 1 diagonal = 36.05551275cm ...

so 2 diagonal, plus 2 widths, plus 2 lengths

(2 x 36.05551275) + (2 x 30) + (2 x 20) = 172.1110255 cm

asks to round to 1 decimal place so answer is 172.1 cm (4 marks)

if there's any typing mistakes please let me know. Hope this is helpful for you

lool got 100 marks by the looks of it but do u know if i would loose marks if i put 9/30 instead of 3/10 (btw u made a mistake hehe 9/30 = 3/10) for question 22b

Also for question 26, i rounded up 36.05 to 36.1 therefore i got an end result of 172.2 do u think i will loose a mark for that as well

21) 4.5 kg oranges + 3kg of apples cost £3.87

2.5 kg oranges cost £1.40. How much does 1kg of apples cost ?

so if 2.5 kg of oranges cost £1.40, 1 kg cost £1.40 / 2.5 = £0.56

so 4.5 kg cost £0.56 x 4.5 which is £2.52

if 4.5 kg oranges + 3kg of apples cost £3.87 then 3 kg of apples costs

£3.87 - £2.52 = £1.35

23) Redlands sends x students, St Sams sends twice as many, Francis send 7 less than Redlands. Each students pays £15, total paid is £1155.

So Redland sends x, St Sams sends 2x and Francis sends x - 7

so total number of students is x + 2x + x - 7 = 4x- 7

total paid is 15 ( 4x - 7) = 60x - 105

This total = £1155 ..... so 60x - 105 = 1155 .... so 60x = 1155 + 105

so 60x = 1260 ... so x = 1260 / 60 = 21

so Redlands sends 21 students St Sams sends 42 and Francis send 14

convert this to cm by multiiplying by 2.54 ... 21.99114858 x 2.54 = 55.85751738 cm

so no, 1 length of ribbon isn't long enough (4 marks)

26) rectangle ...length 30cm, width 20cm PLUS 2 diagonals

so use Pythag to calculate the length of the diagonals

20 squared + 30 squared = 1300 which you then need square root
