In the diagram |XY| = 12cm, |XZ| = 9cm, |ZN| = 3cm and ZY||NM, calculate |MY|
3cm
4cm
5cm
6cm
Correct answer is B
\(\frac{|YM|}{|YX|} = \frac{|ZM|}{|ZX|}\)
\(\frac{|YM|}{12} = \frac{3}{9}\)
|YM| = 3 x \(\frac{12}{9}\)
|MY| = 4cm
In the diagram what is x + y in terms of z?
180o - z
180o + z
z - 180o
z
Correct answer is A
x + y + z = 180(sum of angles in a \(\bigtriangleup\))
x + y = 180 - z
6.28cm
12.6cm
22.6cm
62.8cm
Correct answer is B
Length of arc = \(\frac{\theta}{360 \times 2 \pi r}\)
= \(\frac{72}{360} \times 2 \times \frac{22}{7} \times 10\)cm
= 12.57
= 12.6cm(3 s.f)
If the pass mark was 4. What percentage of the pupils failed the test?
20.0%
37%
62.5%
80.0%
Correct answer is A
No. of pupils that failed = 1 + 3 + 4 + 8
% failed = \(\frac{8}{40} \times 100\)% = 20.0%
