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?

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

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?

ShreyaSimplify square root of 9x/16

lisajtxYou can’t really simplify this, but you could write it as (3/4)^2 times x. Does that make sense?

Selmazarah 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?

lisajtxGreat 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!

FortuneIf 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

lisajtxGreat problem! I actually found this here – does it make sense?

FORTUNEThanks

FORTUNE1. 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

lisajtxFor 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

FORTUNEWhat is the integer part of 15000

lisajtxIt’s just 15000.

FORTUNESimplify (5/x-y)-(4/x-y)

Simplify (4/x+1)-(3/x-1)

lisajtx5/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!

lolaif 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

lisajtxLooks 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 🙂
