Some engines require oil to be mixed with gasoline. for every gallon of gas used, 4 ounces of oil should be added. how much gas is needed if 12 ounces of oil are used?

You need 3 gallons of gas

Work Shown:

(1 gallon gas)/(4 oz of oil) = (x gallons of gas)/(12 oz of oil)

1/4 = x/12

1*12 = 4*x cross multiply

12 = 4x

4x = 12

4x/4 = 12/4 ... divide both sides by 4

x = 3 gallons of gas is needed

answer: since the question is talking about growth you have to use the growth formula which is inital amount (1 + growth)^time

step-by-step explanation:

the intial amount is 1200, the growth is 4.8, and the time is 7. plug those numbers into the equation, also i think you have to change 4.8 into a percent. but, i have forgotton how to do that. if this is a online class go on to the lesson.

18

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.
