Simplify square root of 9x/16
You can’t really simplify this, but you could write it as (3/4)^2 times x. Does that make sense?
zarah and jeremy each have collection of bobbleheads. Zarah said if Jeremy would give her 3 of his bobble heads they would have an equal number, but if Zarah would give Jeremy 3 of her bobble heads, Jeremy would have 2 times as many bobbleheads as she would have left. How many bobbleheads does Jeremy have?
Great problem! I’d do it this way.
Let z = number of bobbleheads that Zarah has, J = number that Jeremy has.
z+3=j-3
j+3=(z-3)*2
Solving, I get Jeremy has 21, Zarah has 15. Hard problem!
If P varies inversely as V and V varies directly as R^2, find the relationship between P and R given that R=7 and P=2
Great problem! I actually found this here – does it make sense?

Thanks
1. If W varies inversely as V and U varies directly as W^3, find the relationship between U and V given that V=2 and U=1
2. Make ‘c’ the subject of formula in
X=(–b+√b^2–4ac)÷2a
For the first problem, here is an explanation – does that make sense? https://quizzerweb.com.ng/study/discuss/13244/mathematics
For the second problem, can you see this link? https://qph.cf2.quoracdn.net/main-qimg-bcb668a5b3b00d8d1e3e31dee8d68879

What is the integer part of 15000
It’s just 15000.
Simplify (5/x-y)-(4/x-y)
Simplify (4/x+1)-(3/x-1)
5/x-y-4/x+y=5/x-4/x=1/x
4/x+1-3/x+1=1/x+2=(1+2x)/x
Hope that makes sense!
if log2p=x and log4q=y ,express p^2q and p/q^2 as powers of 2. If also p^2q=16 and p/q^2=1/32 ,find the values of x and y
Looks interesting. For p^2q, do you mean p^(2q) or p^2(q)? Same for p/q^2 – do you mean (p/q)^2 or p/(q^2)?
Then I can start working on it 🙂

I just allowed the printing on the website again. If you do print, please put the name Mathhints.com on it – it’s copyrighted! Thanks!
How much would you need to learn to take physics with calculus? All of it or just trig and pre cal? Is there an order to take them at? Which would come first?
I would say definitely Alg 1, Alg 2, and Geometry. It would be good to have PreCalc and Trig, but I don’t think necessary. You wouldn’t need to take Calculus first.
How about the math levels for the MCAT? I see they require physics with calculus 1+2. Just the same recommendation as above? Any math classes for chem 1+2 or organic chem 1+2? Or is that just simple algebra?
What is a 2.26 GPA out of 100
From Wyzant:
A GPA of 2.26 corresponds to approximately 72.6%, reflecting a performance in the low C to C+ range.
So I have a real estate math question, If a 1st floor is 100 sq ft and the 2nd floor is 100 sq ft, The living area is 50% for the 1st floor and 50%, for the 2nd floor. But what if the 1st floor is 915 sq ft and the 2nd floor is 924 sq ft I know they are not equal, but how do I calculate the percent difference for each floor totalling 100 %. IE: 50% and 50% or
Any help would be appreciated.
I’m not sure exactly what you are looking for. You can also get percentages for each floor, and then weight them for the total of the house (example, multiply the first by 915/(915+924) and second by 924/(915+924). Does that make sense?
