how is the volume of a solution used in calculating concentration?
Answer:
3
Step-by-step explanation:
((7x-4)^2) - (7x-4)(7x-4) + 3
(7x-4)(7x-4) is 7x-4^2
So its (7x-4)^2 - (7x-4)^2 + 3
(7x-4)^2 cancel out.
Answer is 3
=7(18x9+4)
=7(162+4)
=7x166
=1162
answer=1162
So just divide 27 by 4 1/2 or 4.5, you should get 6 so it would take 6 hours for the snow to get to 27 inches
