Answer:
A) b= 8 students
B) 1) 19/55 2) 28/55
Step-by-step explanation:
I'm sorry if I'm getting this whole concept wrong cause it felt way too easy to be right so I'm sorry if you get it wrong.
The reason the first question is 8 is because of the fact that you first have to add the students charted on the Venn-diagram and subtract that from 55, getting you to 8 students.
For the second one, the first part would be 19/55 becuase in the Venn-diagram it is shown that only 19 people passed both and so that be the numerator and the denominator would be the total of students, so it would be 55.
Same thing for part two except the fact that you have to add the students who only passed one subject, so combine 17 and 11, getting you to 28, thus getting the answer 28/55.

8ft is equivalent to 64ft²
"The chemical is dispensed to completely fill 25 identical cylindrical containers"
So obviously the volume of each is 1/25 of the whole volume, right? So you know V for one of these cylinders.
"each with a radius of 5 in"
V = pi*r^2*h
<span>You know V. You know r. Plug them in. Solve for h. Should take one line.
</span><span>235,500 /25 = 9420 is the volume of 1 cylinder.
</span>h <span>=</span><span>V/</span><span>π</span><span>r</span><span>2</span><span>
</span>h ≈119.94
