A school girl spends \(\frac{1}{4}\) of her pocket money on books and \(\frac{1}{3}\) on dress. What fraction remains?
If \(\frac{x}{a + 1}\) + \(\frac{y}{b}\) = 1. Make y the subject of the relation.
Calculate the total surface area of a cupboard which measures 12cm by 10cm by 8cm
Total surface area of a cupboard, A = 2(lb + bh + lh) L = 12, b = 10, h = 8
A = 2((12 x 10) + (10 x 8) + (12 x 8))
A = 2(120 + 80 + 96)
A = 2 x 296
A = 592cm\(^2\)
Convert 0.04945 to two significant figures
From a point R, 300m north of P, a man walks eastward to a place Q which is 600m from P. Find the bearing of P from Q, correct to the nearest degree
The probabilities that John and James pass an examination are \(\frac {3}{4}\)and \(\frac {3}{5}\) respectively. Find the probability of both boys failing the examination.
Probability (both John and James passed):
= \(\frac {3}{4}\) x \(\frac {3}{5}\)
= \(\frac {9}{20}\)
Pr(john and james failed)= 1- Pr(john and james passed)
= 1 – \(\frac {9}{20}\)
= \(\frac {11}{20}\)
An arc of a circle of radius 14cm subtends angle 300° at the centre. Find the perimeter of the sector formed by the arc (take π = \(\frac{22}{7}\))
Simplify
\(\frac {25 \frac{2}{3} + 25 \frac{1}{6}} {(\frac{1}{5}) \frac{7}{6} \times (\frac{1}{5}) \frac{1}{6}}\)
Make T the subject of the relation.
