Earth’s surface is approximately 70% water. There is no water on the surface of Mars, and its diameter is roughly
Pie

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.

At Dubai metro station, in a week 320 trains arrived. Out of these 5% arrived early and 15% arrived late. How many arrived on ti
dybincka [34]

<u><em>The </em></u><u><em>number of trains</em></u><u><em> that arrived Dubai metro station on time is; 272 trains. </em></u>

<u><em /></u>

  • We are told that 320 trains arrived the Dubai metro station in a week.

  • Now, we are told that 5% got there early and 15% got there late.

This means, the percentage that got there on time is;

100% - % of trains that got there late.

  • Therefore, percentage of trains that got there on time is;

100% - 15% = 85%

  • Since 85% of the trains got there on time, then number of trains that got there on time is;

85% × 320 = 272

  • Therefore, we can conclude that 272 trains arrived on time.
