250% as a fraction is actually 250/100, since it is more than one. This can be simplified to 25/10.
As a mixed number, you take the 25/10 and then take out 2, to get 2 and 5/10, which equals 2 and 1/2.
As a whole number, it's just 2.5.
230 times .30 is 69 so sub that from 230 you get 161
Answer:
ml
Step-by-step explanation:
This is one of those questions where you wish the author had asked for the best 2.

The water itself is most accurately measured in grams or mg.
So what to do.
I think the question intends you to answer mL because it is asking about the glass.
X1=(-16√16^2-4*1*9)/(2*1) = (-16 - 2*√55)/ 2=-15.416
X2=(-16+√16^2-4*1*9)/(2*1) = (-16+2*√55)/2=-0.584
