Question 1

In a pie chart, one sector represents 90°. What percentage of the whole does it represent?

Accepted Answer

25%

Answer

A full circle = 360°. 90° ÷ 360° = 0.25 = 25%. A 90° sector represents one quarter (25%) of the whole circle.

Question 2

What is the next term in the sequence: 3, 7, 11, 15, ___?

Accepted Answer

19

The sequence increases by 4 each time (arithmetic sequence with common difference 4). 15 + 4 = 19.

Question 3

A car travels at 60 km/h. How far does it travel in 2.5 hours?

Accepted Answer

150 km

Answer

Distance = speed × time = 60 × 2.5 = 150 km. 60 × 2 = 120, 60 × 0.5 = 30, total = 150 km.

Question 4

What is the missing angle in a triangle if the other two angles are 65° and 75°?

Accepted Answer

40°

Answer

Angles in a triangle sum to 180°. 65° + 75° = 140°. 180° − 140° = 40°. The missing angle is 40°.

Question 5

Write 72 as a product of its prime factors.

Accepted Answer

2³ × 3²

Answer

72 = 2 × 36 = 2 × 2 × 18 = 2 × 2 × 2 × 9 = 2 × 2 × 2 × 3 × 3 = 2³ × 3². Using a factor tree confirms this.
