Can someone help me check these answers, please.
1. Solve the equation for the indicated variable
A=r+rvf, for v
A. v=A−rrf******
B. v=r−Arf
C. v=(A−r)rf
D. v=A−rf
2. Which is not a valid rearrangement of v=13bh
A.b=3vh
B.v=13hb
C.h=3vb
D.3=bhv******* Thank you so much!
First one is,
v=a-r/rf
Second one is,
B
third one is
t=4 hours
fourth one is
w=4 inches
fifth one is
3=bhv
~ALL CORRECT~
1. nope
A=r+rvf, for v
(A-r) = r v f
v = (A-r) / r f
I suspect it is C but a typo in your list.
2. The only correct one is B
Are you missing / signs and did you type 3 instead of 13 ?
Sorry I ment to put 1/3 instead of 13 for the ones that say 13
still missing divide signs
Sure! Let's go through each question and explain how to find the correct answers.
1. Solve the equation A = r + rvf for the indicated variable v.
To isolate v, we need to get rid of the other terms on the same side of the equation. Here's how:
A = r + rvf
First, factor out v: A = v(r + rf)
Next, divide both sides of the equation by (r + rf) to solve for v:
A / (r + rf) = v
So, the correct answer is D. v = A / (r + rf).
2. Which is not a valid rearrangement of v = 13bh.
To check which option is not a valid rearrangement of the equation, we need to verify if the rearranged equation is equivalent to the original equation.
The original equation is v = 13bh.
Let's check the given options one by one:
A. b = 3vh:
We can rearrange this equation to v = 3hb, which is not equivalent to the original equation. So, option A is not a valid rearrangement.
B. v = 13hb:
This is the same as the original equation, just the order of terms is reversed. So, option B is a valid rearrangement.
C. h = 3vb:
We can rearrange this equation to v = h / (3b), which is not equivalent to the original equation. So, option C is not a valid rearrangement.
D. 3 = bhv:
This equation is not a valid rearrangement because it does not preserve the original structure of the equation. So, option D is not a valid rearrangement.
Therefore, the correct answer is D. 3 = bhv.
