Alocal dairy has three machines to fill half-gallon milk cartons. the machines can fill in the dialy quota in 6 hours, 7 hours, and 5.25 hours, respectively. find how long it takes to fill the daily quota if all three machines are running. it takes _ hours to fill the daily quota if all three machines are running. show me how to do this, and i will give a medal. i think the beginning equation is: 1/6+1/7+1/5.25=1/x. my answer is 0.50 hours, nut i just want to be sure. you!

1/x = 1/2 That's what you got with your equation. So far so good. That does not tell you what x is though. You have go just a bit further.

1/x = 1/2 Cross multiply

x = 1 * 2

x = 2 It takes 2 hours to complete with all three machines working.

answer: a) (0,0), (1,1), (2,8), and (3,27).

step-by-step explanation:

0^3=0

1^3=1

2^3=8

3^3=27

in effect, the exponential equation for this would me y=3^x. each x-coordinate cubed is giving the y coordinate, so a is your answer : )

b

step-by-step explanation:

the word superfluous means unnecessary
