On average, a commercial airplane burns about 3.9 × 10³ milliliters of gasoline per second. there can be as many as 5.1 × 10³ airplanes in the air in the united states at any given time. about how many milliliters per minutes of gasoline are burned by commercial airplanes in the united states at any given time?

60 x 3.9x10-3 = 234x10e3ml/minute/plane

You have 5.1x10e3 planes in the air

(234 x 5.1) (10e6) ---you add the two exponents together for this one

1193.4 x 10e6...which turns into 1.2 x 10e9

im not quite sure if this is right but i got 5.6 oisutuve

step-by-step explanation:

the ratio of white tiles to blue tiles is 48: 16. the ratio in it's simplest form is 3: 1.

step-by-step explanation:

ratio: take the first number and add a colon next to it, then add the second number after that. make sure the ratio order matches up with the written problem!

simplest form: we can simplify the ratio 48 : 16 by dividing both terms by the greatest common factor (gcf).

the gcf of 48 and 16 is 16.

divide both terms by 16:

48 ÷ 16 = 3

16 ÷ 16 = 1

reducing to simplest form:

48 : 16 = 3 : 1
