You can proceed like this,
650 kb for a pic
and 2200kb for song ( 650 + 1550)
total= 18150 kb and 16 files
so, 650 kb each in both pic and song = 16 * 650= 10400
remaining = 18150-10400 = 7750 , which is contributed by additional 1550 of songs that is
7750/1550 = 5
so, a total of 5 songs and 11 pictures were sold..
hope it helped
Answer:
Earth
Step-by-step explanation:
You don't need scientific notation.
The areas of similar figures are proportional to the square of their linear scale factor. If Mars is 1/2 the diameter of Earth, its total surface area is (1/2)² = 1/4 that of Earth.
That is, the land area of Mars is 25% of the total area of Earth.
The land area of Earth is 1-70% = 30% of the total area of Earth. 30% is more than 25%.
Earth has more land area than Mars.
