25m/s
150m/s
250m/s
500m/s
Correct answer is A
\(\frac{720 \times 1000}{8 \times 60 \times 60}\) = \(\frac{20 \times 10}{8}\)
= \(\frac{200}{8}\)
= 25 m/s
The nth term of a sequence is Tn = 5 + (n - 1)2. Evaluate T4 - T6
30
16
-16
-30
Correct answer is C
T4 = 5 + (4 - 1)2; where n = 4
= 5 + (3)2 = 5 + 9
= 14
T = 5 + (6 - 1)2
where n = 6
= 5 + (5)2
= 5 + 25 = 30
T4 + T6 = 14 - 30
= -16

Correct answer is B
Divide cash enrollment by their common factors then the answer of each division gives the required ratio. i.e. x = \(\frac{1050}{70}\) = 15
and y = \(\frac{1190}{70}\) = 17
ratio of enrollment of x to y = 15:17
Simplify; \(\frac{3\sqrt{5} \times 4\sqrt{6}}{2 \sqrt{3} \times 3\sqrt{2}}\)
\(\sqrt{2}\)
\(\sqrt{5}\)
2\(\sqrt{2}\)
2\(\sqrt{5}\)
Correct answer is D
\(\frac{3\sqrt{5} \times 4\sqrt{6}}{2 \sqrt{3} \times 3\sqrt{2}}\)
= \(\frac{\sqrt{5} \times 2\sqrt{6}}{\sqrt{2} \times \sqrt{3}}\)
= \(\frac{\sqrt{5} \times 2 \sqrt{6}}{\sqrt{6}}\)
= 2\(\sqrt{5}\)
