Remaining water in the tank is (19/2-19/3) gallons = 57-38/6=19/6 =3 1/6 gallons
Rewriting the formula in standard form would be x^2-8x+14=0
V+27=117
Subtract 27 to 117:
v=90
2400/20000 = 0.12;
6750/75000 = 0.09;
Because 0.12 > 0.09, Smallille has a larger unemployed problems than Bigtown.
I do not agree. If you divide 240 by 30, it would be 8 heartbeats, which is absurd. It's impossible for something to survive with 8 heartbeats per 30 seconds.
In order to get the CORRECT answer, divide 240 by 60 seconds.
This would give you 4 heartbeats per second.
Then, multiply it by 30 seconds, which would give you 120 heartbeats.
CORRECT answer: 120
