Asupersonic aircraft consumes 5320 imperial gallons of kerosene per hour of flight and flies an average of 14 hours per day. it takes roughly seven tons of crude oil to produce one ton of kerosene. the density of kerosene is 0 965 g/cm . how many planes would it take to consume the entire annual world production of 4 02 10 metric tons of crude oil?

5320*14= 74480 gallons. 
First let us convert gallons to cm^3 and we get 2.819374858x10^8 cm^3. 
We then multiply with density and then times 1000 to get it in terms of tons. 
Then multiply the number by 7 to get how many tons of crude oil a single plane uses in 14 hrs. 
Finally divide this by the production of crude oil. 

I got 4737 airplanes.

answer: good job it's all correct !

explanation:

answer;

d. are made mostly of liquid

explanation;

-the general   composition and structure planets includes; they have a thick gas and liquid layer covering a small,solid core. mostly the gases are hydrogen and helium atmosphere and layers of liquid hydrogen. for instance neptune and uranus are examples of the outer planets, they have a core covered by ice and ammonia.

-neptune's atmosphere is hydrogen and helium with a bit of methane so there is no oxygen to breath and the interior is made up of frozen water and ammonia with a rock and iron core. thus, there is no liquid water or solid surface to survive.
