John, after throwing 350 completions at a rate of 70%, has attempted 500 passes this year.
The question pertains to percentages, specifically it is asking us to find out how many passes John attempted this year if we know he completed 350 passes which represent 70%. Since 350 passes represent 70% of all the passes he attempted, we can use this information to find 100%, or total attempts. We divide 350 by 70 to find out what 1% represents, which gives us 5. Since 1% is equal to 5 passes, to find out the total (100%), we multiply 5 by 100. Which gives us 500. Therefore, John has attempted 500 passes this year.

The order of volume from least to greatest is C, B and A.
Step-by-step explanation:
Given:
Three Cylinders namely A, B, and C with different heights have the same radius.
To Find:
Arrange the cylinders from least to greatest with respective to their volume.
Formula for volume of cylinder:
V=
i.e V∝ h (for constant radius)
where,
r = radius of cylinder
h = height of cylinder
we see that Volume is directly proportional to height.
Consider, are the heights of cylinder A,B,C respectively, such that;
> >
And, are the volume of cylinder A,B,C respectively.
So the order of volume will also be,
> >
