Planet earth has a mass of 5.9726x10 to the 24th power kilograms. and although 70% of the earths surface is made of water the waters mass is only 5x10 to the negative fourth power percent of the earths total mass. use scientific notation to estimate the mass of the planets water

i think asking google will you get the answer to that question

1. minimum

2. 6400

3. eight

hope this !

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is

step-by-step explanation:

mean or average is 40.6
