96cm2
72cm2
60cm2
24cm2
Correct answer is C
|VU| = |UT| = |TS|
|VS| = (4.8) x 3 = 14.4cm
|PQ| = |QR| = 4.8
|PR| = (4.8) x 2 = 9.6cm
Since quad. PRSV is a trapezium of height 5cm
Area of quad. PRSV = \(\frac{1}{2}(a + b)h\)
= \(\frac{1}{2}(14.4 + 9.6) \times 5\)
= \(\frac{1}{2}(24) \times 5\)
12 x 5 = 60cm2
6.8m
14.5m
17.7m
34.3m
Correct answer is B
Sin 65o = \(\frac{x}{16}\)
x = 16x sin 65
= 16 x 0.9063
x = 14.5m
Simplify \(\frac{20}{5\sqrt{28} - 2 \sqrt{63}}\)
\(\frac{5\sqrt{7}}{7}\)
\(\frac{5\sqrt{5}}{7}\)
\(\frac{7\sqrt{5}}{7}\)
\(\frac{7\sqrt{7}}{5}\)
Correct answer is A
\(\frac{20}{5 \sqrt{4 \times 7} - 2\sqrt{9 \times 7}}\)
\(\frac{20}{10 \sqrt{7} - 6\sqrt{7}}\)
= \(\frac{20 \sqrt{7}}{4 \sqrt{7}}\)
= \(\frac{5\sqrt{7}}{7}\)
-6oC
-4oC
4oC
8oC
Correct answer is B
Temperature = -5oC
It fell by 6oC = -5oC - 6oC
= -11oC
Then rose by 7oC = -11 + 7
= -4oC (final temperature)
