### INFORMATION FOR CANDIDATES

The number of marks is given in brackets [ ] at the end of each question or part question.

**SECTION A [52 marks]**

Answer all questions in this section

## Question 1
### (a)

Estimate \(1,98+8,75 \times 6,05\) by first rounding off the given numbers

$$
6,89
$$

to the nearest whole numbers.

### (b)

### (c)

Simplify \(2 \frac{1}{2} \div 3 \frac{3}{4}+1 \frac{1}{5}\).

## Question 2
### (a)

In a group of 160 form one learners at a sports academy, all learners play at least one of the ball games volleyball, netball or tennis.
40 learners play netball only.
25 play tennis only.
28 play Volleyball only.
50 play netball and tennis.
35 play netball and Volleyball.
30 play tennis and volleyball.
\(x\) play all the three games.

#### (i)

The diagram above is an incomplete Venn diagram of the information. Copy and complete the Venn diagram by inserting the number of learners in each part of the sets in terms of \(x\).

#### (ii)

Find the value of \(x\).

### (b)

The universal set, \(\xi\), has subsets A and B such that:
\(\xi=\{x: 1 \leq x<10, x \in \mathbb{Z}\}\)
A is a set of odd numbers
B is a set of factors of 10

#### (i)

List all elements of set A.

#### (ii)

Find \(n\left(A^{1} \cap B\right)\).

## Question 3
### (a)

A rectangular vegetable garden has a length of \(50,7 \mathrm{~m}\) and a width of \(30,5 \mathrm{~m}\). Inside the garden there is a circular reservoir of radius \(1,4 \mathrm{~m}\). The remaining space is for growing vegetables.

In this question take \(\pi\) to be \(\frac{22}{7}\).

#### (i)

Calculate the area covered by the reservoir.

#### (ii)

It costs \($ 38507\) to spray the space for growing vegetables. Find the cost per square metre of spraying the space for growing vegetables.

Give the answer to the nearest dollar.

### (b)

The diagram shows a sector AOB of a circle centre O and radius \(r \mathrm{~cm}\).
The arc AB subtends an angle of \(60^{\circ}\) at the centre of the circle.
In this question take \(\pi\) to be \(\frac{22}{7}\).

#### (i)

The length of \(\operatorname{arc} \mathrm{AB}=11 \mathrm{~cm}\).

Calculate the radius of the circle.

#### (ii)

Hence or otherwise calculate the area of the sector.

## Question 4
### (a)

The cost, C, for a birthday party at a lodge is partly constant and partly varies with the number, n, of people attending. If there are 5 people attending the cost is \($ 700\), and it costs \($ 1340\) for 13 people attending.

#### (i)

Express the cost, C, in terms of \(n\) and constants \(h\) and \(k\).

#### (ii)

Find the value of \(h\) and the value of \(k\).

#### (iii)

Calculate the cost if 25 people attend.

### (b)

\(P\) varies directly as \(Q\). \(P=12\) when \(Q=5\).

#### (i)

Find the formula connecting \(P\) and \(Q\).

#### (ii)

Calculate the value of \(Q\) when \(P=42\).

## Question 5
Answer the whole of this question on a sheet of plain paper.
Use ruler and compasses only for all constructions and show clearly all construction lines and arcs.
All constructions should be done on a single diagram.

### (a)

Construct triangle \(ABC\) such that \(AB=10 \mathrm{~cm}, A\hat{B}C=45^{\circ}\) and \(B\hat{A}C=60^{\circ}\).

### (b)

Construct the locus of points that are,

#### (i)

\(4,5 \mathrm{~cm}\) from \(B\),

#### (ii)

\(1,5 \mathrm{~cm}\) from \(AB\) on the same side of \(AB\) as \(C\).

### (c)

Point P lies inside the triangle and is such that \(BP \leq 4,5\) and P \(\geq 1,5 \mathrm{~cm}\) from \(AB\).
Shade clearly the region in which P lies.

### (d)

Measure and write down the length of AC.

**SECTION B [48 Marks]**

Solve the equation

$$
\frac{2 a+3}{4}+\frac{a-5}{3}=1
$$

### (b)

It is given that \(M=\frac{N}{N+P}\).

#### (i)

Give the answer as a fraction in its lowest terms.

#### (ii)

Make N the subject of the formula.

### (c)

Solve the equation

$$
\log _{3}(x-2)^{2}=2
$$

## Question 7
A group of 100 form 2 learners was asked to give ages in years of their grandfathers. The information is shown in the table below.

| Age ( \(x\) ) in years | \(50 \leq x<55\) | \(55 \leq x<60\) | \(60 \leq x<65\) | \(65 \leq x<70\) | \(70 \leq x<75\) | \(75 \leq x<80\) |
