#3 Which of the following is less than 527 m?

A. 0.000699 Mm = 0.000699 · 1,000,000 m = 699 m

B. 914,879,710 nm = (914,879,710 : 1,000,000,000) m = 0.914879710 m

C. 51,723 cm = (51,723 : 100) m = 517.23 m

The best answer is C

#4 How many songs would you have if the average file size is 4,000 kb?

8 gb: 1,700 songs

16 gb: 6,000 songs

2 gb: 500 songs

160 gb: 30,000 songs

64 gb: 14,000 songs

1 Terabyte = 1024 gb: so im guessing 350,000 songs

This depends on the length of the song and the file format/type. A typical mp3 song of around 4 minutes averages 4 MB (4000 KB).
