A^2 + b^2 = c^2
9^2 + b^2 = 12^2
81 +b^2 = 144
-81 (subtract 81 from both sides of the equation)
b^2 = 63
b = square root of 63
X=weight of the jug
y=witht of liquid when the jug is full
we suggest this system of equations:
x+y/5=250
x+4y/5=550
we solve this system of equations by equalization method.
x=250-y/5
x=550-4y/5
250-y/5=550-4y/5
least common multiple=5
1250-y=2750-4y
-y+4y=2750-1250
3y=1500
y=1500/3
y=500
x=250-y/5
x=250-500/5
x=250-100
x=150
Answer: weight of the jug = 150grams.
1/15 would be the simplest form 3x5=15
I'm gonna say C for this one
