Problema Solution

Write 57.9 million in meters using scientific notation.

The diameter of Venus is 102 x 10^4km

Mars diameter is 6.79x10^3km

How many times larger is the diameter of venus than mars?

The diamiter of Venus is 95% of Earths. What is Earths diameter?

saturns density is 0.687g per cubic centimeters, it would float in water. Mercury is 8.03 times greater. What is the density on Mercury? round to the nearest 100th.

Answer provided by our tutors

(1)57.9 million meters = 5.79*10^7 meters

(2) 102 x 10^4km/ 6.79x10^3km = 150.2 times

So the diameter of venus is 150.2 times larger than mars

(3)

The Earths diameter = 102 x 10^4km/95% = 107.4*10^4 km

(4)

the density on Mercury = 8.03*0.687g per cubic centimeters = 5.517g per cubic centimeters
