Correct answer is A
Error =12.75 - 7.50 = 5.25
Error % = \(\frac{5.25}{12.75}\) x 100% = 41.2%
A car is travelling at an average speed of 80km/hr. Its speed in meters per second (m/s) is
13.3m/s
22.2m/s
133.3m/s
222.2m/s
1333.3m/s
Correct answer is B
80km/h = \(\frac{80}{60}\) x \(\frac{1000}{60}\) = 3 x 3= \(\frac{40 x 5}{9}\)
= \(\frac{200m/s}{9}\) = 22.22m/s
N1045
N605
N545
N490
N440
Correct answer is C
Husband contributions = \(\frac{7}{100}\) x N5,500 = N385
Wife contribution = \(\frac{4}{100}\) x N4,000 = N160
Sum of their Annual contribution = N385 + N160 = N545
1cm
2cm
4cm
8cm
16cm
Correct answer is D
r= 4cm; base area = \(\pi\)r2; Curve S.A = 2\(\pi\)rh
\(\frac{base area}{curved area}\) = 1/4; \(\pi\)/2\(\pi\)rh
=h = \(\frac{4 x 4cm}{2}\)
h= 8cm
If 2x + y = 7 and 3x - 2y = 3, by how much is 7x greater than 10?
1
3
7
10
17
Correct answer is C
2x + y = 7 = i
3x - 2y = 3 = ii
i x 2 + ii = 4x + 2y = 14
\(\frac {3x - 2y = 3}{7x = 17}\)
x = \(\frac {17}{7}\) = 7x = 17 x 1/7 x 7
17 - 10 = 7
