Which of the following bearings is equivalent to S50°W?
040o
130o
220o
230o
Correct answer is D
p>S50°W = 180° + 50°
= 230°
315o
270o
225o
135o
Correct answer is C
The bearing of Kofi from the building = 180° + 45°
= 225°
4√2km
8km
8√2km
16km
Correct answer is C
\(x^2 = 8^2 + 8^2\)
\(x^2 = 64 + 64 = 128\)
\(x = \sqrt{128}\)
= \(8\sqrt{2}\) km
N1250
N1578
N1875
N3125
Correct answer is C
Price of television = N25,000
Paid N10, 000
Remainder = N(25,000 - 10,000)
= N15,000
Eight equal installments = \(\frac{15,000}{8}\)
= N1,875 per installment.
A car moves at an average speed of 30kmh\(^{-1}\), how long does it take to cover 200 meters?
2.4 sec
24 sec
144 sec
240 sec
Correct answer is B
Speed = 30 kmh\(^{-1}\)
= \(\frac{30 \times 1000}{3600}\)
= \(\frac{25}{3} ms^{-1}\)
Time = \(\frac{Distance}{Speed}\)
= \(\frac{200}{\frac{25}{3}}\)
= \(\frac{200 \times 3}{25}\)
= 24 seconds
