Simplify(0.3 x 105) \(\div\) (0.4 \(\times\) 107), leaving you answer in the standard form.
7.5 x 10-4
7.5 x 10-3
7.5 x 10-2
7.5 x 10-1
Correct answer is B
\(\frac{0.3 \times 10^5}{0.4 \times 10^7} = \frac{3 \times 10^{-1} \times 10^{5}}{4 \times 10^{-1} \times 10^7}\)
\(\frac{3 x 10^4}{4 x 10^4}\)
\(\frac{3}{4}\) x 104-6 = 0.75 x 10-2
= 7.5 x 10-3

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
