2.7
EDDIE SAYS
Use the Square Root (√) button.
• Question 5

Work out:

¾ of 128

96
EDDIE SAYS
On your calculator, work out 128 ÷ 4. This gives one quarter of 128.
Multiply by 3 to get three-quarters.
• Question 6

Pens cost £1.35 each.

Ann has £20 to spend on pens.  She buys the greatest number possible.

Work out the number of pens Ann buys.

14
EDDIE SAYS
20 ÷ 1.35 = 14.814814814....
She cannot buy 0.814814814... of a pen.
• Question 7

Solve:

2y - 5 = 12

y = 8½
EDDIE SAYS
2y - 5 = 12

Add 5 to both sides to get
2y = 17

Halve both sides to get
y = 8½
• Question 8

Calculate the area of the trapezium shown below in cm2.

(Just write the number)

72
EDDIE SAYS
Area = ½(6 + 12)× 8 = ½ × 18 × 8 = 9 × 8 = 72 cm²
• Question 9

## Column B

the smallest prime number
17
The largest prime number
23
A square number
25
A multiple of 7
21
EDDIE SAYS
The prime numbers are 17, 19 and 23.
25 is 5 squared.
21 is 3 × 7;
• Question 12

Round this number to 2 significant figures:

18742

19000
EDDIE SAYS
18742 is nearer to 19000 than to 18000.
The 1 and the 9 are the first two significant figures.
• Question 13

18.9 x 2.331

44.06
EDDIE SAYS
Using a calculator, the answer is 44.0559.
The third decimal place is 5, which is a high number, so the answer is 44.06
• Question 14

Ahmed goes on holiday to Italy and changes £750 into euros (€) before he goes.

The exchange rate is £1 = €1.12.

In Italy, he spends €480 euros and brings the remaining euros home.

He changes these euros back into pounds.

The exchange rate is now £1 = €1.20.

How much money in pounds does he get back?

(Just write the number)

300
EDDIE SAYS
£750 = 750 × 1.12 = €840
He spends €480 so has 840 - 480 = €360 left
€360 = 360 ÷ 1.20 = £300
• Question 15

Simplify

5a + 8b - 2a + b

3a+9b
EDDIE SAYS
Collect the a terms to get: 5a - 2a = 3a
Collect the b terms to get: 8b + b = 9b
• Question 16

Calculate the area of the following shape made of rectangular pieces.

(Just write the number)

17.6
EDDIE SAYS
Divide the shape into a 3 by 3 square and a 4.3 by 2 rectangle.
Area = 3 × 3 + 2 × 4.3 = 9 + 8.6 = 17.6 m²
• Question 17

The Triangle ABC is isosceles.

Calculate the angle marked a°.

74
EDDIE SAYS
∠ABC is opposite and equal to the angle marked as 32°
a° + a° = 180 - 32 = 148°
a° = 148 ÷ 2 = 74°
• Question 18

Calculate the length of the side BC in cm in the following triangle.

(Just write the number to 2 decimal places)

9.49
EDDIE SAYS
Using Pythagoras' Theorem, BC² = 3² + 9² = 9 + 81 = 90

BC = √90 = 9.4868....
• Question 19

Here is a sign showing the prices for using a car park.

 CAR PARK £1.75 for the first hour £1.25 for each hour after

Jane pays £9.25 to park.

For how many hours does she park?

(Just write the number)

7
EDDIE SAYS
£9.25 - £1.75 = £7.50
£7.50 ÷ 1.25 = 6
• Question 20

Match the most suitable measurement to each item.

## Column B

Mass of a drawing pin
1g
Mass of an apple
100g
Height of a bus
4.4m
Height of a table
56cm
Height of Tower of Pisa
56m
• Question 21

Use trial and improvement to find a solution to the equation

x3 - 2x = 31

The first step is shown below.

Give the solution to 1 decimal place

x  x3 - 2x  Comment
3  33 - 2×3 = 27 - 6 = 21  too small

3.4
EDDIE SAYS
3.4³ - 2×3.4 = 32.504 too big
3.3³ - 2×3.3 = 29.337 too small
3.35³ - 2×3.35 = 30.895375 still too small
So answer lies between 3.35 and 3.4, which will give a solution of 3.4 to 1 decimal place.
• Question 22
 Find the volume of the following cuboid in cm3 to the nearest whole number. (not drawn accurately)

a = 14 cm

b = 8.2 cm

c = 6.5 cm

(Just write the number)

746
EDDIE SAYS
Volume = 14 × 8.2 × 6.5 = 746.2 cm³
• Question 23

Factorise

6x + 10y

2(3x+5y)
EDDIE SAYS
The HCF of 6 and 10 is 2, so 2 goes outside the brackets.
To find the inside terms, divide 6x and 10y by 2.
• Question 24

The maximum daytime temperatures in ºC on 9 British summer days were as follows.

Work out the mean maximum temperature in ºC to 1 decimal place.

(Just write the number)

18,  17,  19,  18,  20,  15,  17,  18,  16

17.6
EDDIE SAYS
The total is 158
158 ÷ 9 = 17.555555555... which rounds to 17.6
• Question 25

My garden consists of a rectangular lawn with a circular pond, as shown below.

Calculate the area of grass in m2 to 3 significant figures.

(Just write the number)

65.4
EDDIE SAYS
Area of garden = 12 × 6.5 = 78 m²

Radius of pond = half of 4 m = 2 m
Area of pond = π × 2² = 12.566 m²

Area of grass = 78 - 12.566 = 65.434 ≅ 65.4 m²
