Question

a circular container is 1/3 full of water. after 20 m^3 of water was added into, the container is now 7/9 full. what is the volume of the container when full?

Answer 1

here's a hint \[\frac 13 x + 20 = \frac 79 x\]
where x = volume of container when full

solve for x

does that help?

Answer 2

@lgbasallote does the answer is 44.4444?

Answer 3

x = 45

Answer 4

i don't think so...check again

Answer 5

remember to change 1/3 into common denominator

Answer 6

if you change 1/3 into common denominator you get \[\implies \frac 39 x + 20 = \frac 79 x\]
try to solve for x again then tell me what you get @Simonbane
