What is a practice skill?

A practice skill is a focused topic or question type designed to help students practise one curriculum-aligned concept with instant feedback and explanations. Skill Align uses practice skills to organise questions by year level, subject, strand, and curriculum focus.

WACE Year 12 Mathematics Essential Depreciation hard text

1. A laptop worth $4200 depreciates by 18% p.a. on a reducing-balance basis. What is its value after 3 years, to the nearest cent?

Choices

$2,315.75
$3,444.00
$2,268.00
$2,904.77

Explanation:

Reducing-balance depreciation gives V = 4200(0.82)³ = 2315.7456, so the value is $2315.75 to the nearest cent.

WACE Year 12 Mathematics Essential Loans and recurrence hard text

2. A loan balance follows Bₙ₊₁ = 1.006Bₙ - 420 with B₀ = 12000. What is B₂, to the nearest cent?

Choices

$11,301.91
$11,652.00
$12,072.00
$10,812.00

Explanation:

B₁ = 1.006 × 12000 - 420 = 11652. Then B₂ = 1.006 × 11652 - 420 = 11301.912, so B₂ is $11,301.91.

WACE Year 12 Mathematics Essential Scale and cost hard scale plan

3. A car park is 6.8 cm by 4.5 cm on a 1:500 plan. Resurfacing costs $18 per square metre. What is the resurfacing cost?

Choices

$13,770
$1,377
$7650
$18,360

Explanation:

The actual dimensions are 34 m by 22.5 m, so the area is 765 m^2. At $18 per square metre, the cost is 765 × 18 = $13,770.

WACE Year 12 Mathematics Essential Conditional probability hard text

4. Machine A makes 55% of items with defect probability 0.04. Machine B makes 45% of items with defect probability 0.07. What is the probability a randomly selected item is defective?

Choices

0.0535
0.1100
0.0315
0.0550

Explanation:

Add the defective branches: 0.55 × 0.04 + 0.45 × 0.07 = 0.022 + 0.0315 = 0.0535.

WACE Year 12 Mathematics Essential Networks hard text

5. A minimum cable network uses selected edges with lengths 6 m, 8 m, 5 m, 9 m, and 7 m. What total cable length is needed?

Choices

35 m
30 m
40 m
45 m

Explanation:

A minimum spanning network connects all required points without a loop. Add the selected edge lengths: 6 + 8 + 5 + 9 + 7 = 35 m.

WACE Year 12 Mathematics Essential Utility modelling hard text

6. A water bill charges a fixed $83 plus $2.18 per kilolitre. A household uses 1.4 kL per day for 92 days. What is the total bill, to the nearest cent?

Choices

$363.78
$280.78
$211.84
$446.78

Explanation:

The usage is 1.4 × 92 = 128.8 kL. The usage charge is 128.8 × $2.18 = $280.78 to the nearest cent. The total bill is $83 + $280.78 = $363.78.

What this practice and exercise page covers

Mathematics Essential practice sits inside WACE Mathematics Year 12 coverage for number, algebra, calculus, statistics, probability, networks, finance, trigonometry, and modelling, with Skill Align keeping the route focused on the selected maths pathway.

Senior practice is organised by pathway, unit, topic, and mode so students can revise targeted areas rather than sitting a full-paper workflow every time. Skill Align treats practice questions and exercise questions as the same learning workflow: students answer curriculum-aligned questions, review explanations, and move between exercise mode and test mode.

Start with the public sample questions to check the question style, then use the curriculum coverage page to choose a topic that matches the student's current classwork.

Preview question styles

Number and financial maths: Students practise number and financial maths through short targeted questions, explanations, and mode-specific feedback.
Measurement and practical geometry: Students practise measurement and practical geometry through short targeted questions, explanations, and mode-specific feedback.
Algebra and graphs: Students practise algebra and graphs through short targeted questions, explanations, and mode-specific feedback.
