Earth has a surface area of approximately 197,000,000 square miles and a total land area of approximately 58,000,000 square miles. what fraction of the earths surface is land? write another fraction that is close to your answer and has a denominator of 10

The desired fraction is 58/197, or approx. 0.29.  This is equivalent to 29/100, or 30/100, or 3/10.

Step-by-step explanation:

Given : Earth has a surface area of approximately 197,000,000 square miles and a total land area of approximately 58,000,000 square miles.

Then fraction of the earths surface is land is given by :-

Hence , the fraction of the earths surface is land =

since 58≈60 and 197≈200

Another fraction that is close to answer and has a denominator of 10=

answer:

total cost for tiles and paints is $924.  

step-by-step explanation:

we have been given that a community hall is in the shape of a cuboid. the hall is 40m long 15m high and 3m wide.

the paint will be required for 4 walls and ceiling.

let us find area of walls and ceiling.

therefore, the area of walls and ceiling is 1410 square meters.

given: cost for 10 litre of paint is $10 and 10 litre paint covers 25 square meter. therefore,

therefore, the total painting cost is $564.

tiles will be required for floor. let us find the area of floor.

given: 1m squared floor tiles costs $3. so,

therefore, the total tiles cost is $360.

now let us find combined total cost of tiles and paint.

therefore, the combined total cost of tiles and paint is $924.
