Correct Answer: C. provide cheap services to all citizens

Correct Answer: D. The believers to be patient and persevere

Explanation

(a) \(\frac{\frac{3}{4}(3\frac{3}{8} + 1\frac{5}{8})}{2\frac{1}{8} - 1\frac{1}{2}}\)

\(\frac{3}{4}(3\frac{3}{8} + 1\frac{5}{8}) = \frac{3}{4}(\frac{27}{8} + \frac{13}{8})\)

= \(\frac{3}{4}(\frac{40}{8})\)

= \(\frac{15}{4}\)

\(2\frac{1}{8} - 1\frac{1}{2} = \frac{17}{8} - \frac{3}{2}\)

= \(\frac{17}{8} - \frac{12}{8}\)

= \(\frac{5}{8}\)

\(\therefore \frac{\frac{3}{4}(3\frac{3}{8} + 1\frac{5}{8})}{2\frac{1}{8} - 1\frac{1}{2}} = \frac{15}{4} \div \frac{5}{8}\)

= \(\frac{15}{4} \times \frac{8}{5}\)

= \(6\)

(b) \(\log_{10} 2 = 0.3010 ; \log_{10} 3 = 0.4771\)

\(\log_{10} 1.125 = \log_{10}(\frac{1125}{1000})\) (Dividing through with 125)

= \(\log_{10} (\frac{9}{8})\)

= \(\log_{10} 9 - \log_{10} 8\)

\(\log_{10} 9 = \log_{10} 3^{2} = 2\log_{10} 3 = 2 \times 0.4771 = 0.9542\)

\(\log_{10} 8 = \log_{10} 2^{3} = 3\log_{10} 2 = 3 \times 0.3010 = 0.9030\)

\(\therefore \log_{10} (\frac{9}{8}) = 0.9542 - 0.9030 = 0.0512\)

\(\approxeq 0.051\) ( 2 significant figures)

Correct Answer: B) Audio

Explanation

MP3 stands for MPEG-1 Audio Layer 3, and it is a compressed audio file format. This means that it takes up less space on a computer or other storage device than other types of audio files, while still maintaining a high level of sound quality. MP3 files can be played on a wide range of devices, including computers, smartphones, and MP3 players.

It is important to note that while MP3 is primarily used for audio files, it is possible to include video content in an MP3 file using certain software tools. However, this is not a common use for the format.

In summary, MP3 file format is associated with audio files. It is a compressed audio file format that is widely used for music and other audio files and can be played on a variety of devices.

(iii) Africans were elected into the Legislative Council

(iv) The activities unified 1: the nationalists in British West African towards fighting a common cause.

(v) Introduction of elective principle it some British West African countries was followed by the springing up of political parties, e.g. NNDP in Nigeria and NCSL of Sierra Leone.

(vii) The congress did not 1 get the co-operation of West African traditional rulers who considered the body as a rival group that intended td usurp their powers.

(viii) The colonial governors used divide and rule tactics on the members of the Congress which eventually led to its demise.

(ix) It brought about policy changes, e.g. abolition of Nigeria Council.
