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
0.29
0.75
0.86
0.93
Correct answer is C
Let the number = d.
\(\log d = \bar{1}.8732\)
\(\log \sqrt{d} = \frac{\bar{1}.8732}{2}\)
= \(\frac{\bar{2} + 1.8732}{2}\)
= \(\bar{1}.9366\)
\(\therefore \sqrt{d} = Antilog (\bar{1}.9366)\)
= 0.86
Given that \(log_4 x = -3\), find x.
\(\frac{1}{81}\)
\(\frac{1}{64}\)
64
81
Correct answer is B
\(\log_4 x = -3\)
\(x = 4^{-3}\)
= \(\frac{1}{64}\)
