Gosh I hope you didn't have to turn this in yet. I'll help you with 4 and 5.

If you want to find the unit rate, you're finding out how much money it is per ounce.
Divide your cost by the number of ounces.

So for example, 3.98 / 16.

After you get your answers, write them down. Whichever answer is the lower number is the better buy because each ounce costs less.

Ainat [17]

Answer:

1,498,454,000 sq. miles

Step-by-step explanation:

Volume of a sphere = 4/3 (3.14) r^3

So since the diameter is 1420 miles, the radius would be half.

V = 4/3 x (3.14) x 710^3

V=4.18666667 x 357,911,000

V = 1,498,454,054.5 but if you want it rounded to the nearest thousand then it'd be 1,498,454,000.
