The approximate total surface area of earth is 5.1 x 10^8 Km^2 .All the salt water on earth has an approximate surface area of 352,000,000 Km^2 , and all the freshwater on earth has an approximate surface area of 9 x 10^6 Km^2. How much of Earth's surface is covered in water, including both salt and fresh water? Wrte your answer in scientific notion.

this was already solved by me with a different person. if you look it up in the search bar at the top of the page, you will get the answer.

step-by-step explanation:

go on the tube you might find some information there

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.

answer: -0.5 would be the most likley outcome
