Question

the table shows the diameters of mercury, mars, and jupiter as well as their distances from earth. use a single - digit times a power of 10 to estimate mercurys diameter. (round to the nearest whole number) mercurys diameter is about □×10□ planet diameters and distance from earth planet mercury mars jupiter diameter (km) 4,878 6,780 139,822 distance from earth (km) 91,691,000 78,340,000 628,730,000

Explanation:

Step1: Identify the diameter of Mercury

The diameter of Mercury is 4878 km.

Step2: Write in scientific - notation

To write 4878 in scientific notation, we move the decimal point 3 places to the left. So, \(4878 = 4.878\times10^{3}\). Rounding 4.878 to the nearest whole number gives 5.

Answer:

5×10³
