If a = 2b and b = 1/3c, what does (c)a equal?

Not a clue. I have a lot of difficulty with algebra.

1/3?
I remember almost no algebra, so I'm sure I did that wrong.

I have no idea what (c)a is supposed to mean. In standard algebraic notation, it'd just be the product of c and a (the parenthesis meaning nothing) and the answer would be 6b^2 which isn't one of the choices.

I think it's 1 divided by (3c), not (1/3)c, so one of the answers is correct...

I hate fractions.

Ooohhh. That would change everything.

I'm guessing this is about ratios. So it's either 2/3 or 1 1/2 depending on what the notation means (which I've never seen used anywhere).

*head explodes*

I would guess 6b, which isn't one of the choices.

Not many math experts here.
I took the formula to be asking for c * a
a=2b b=1/3c so, if a=2b then putting 'a' into terms of 'b' and 'c' would be a = 2*(1/3c)

so then for c * a, it would be c * 2(1/3c), or 2/3. Clear as mud, right?

don't know. I'm not a math type.

I believe there may be a problem with how it equation is written.

If a = 2b and b = 1/3c, what does (c)a equal?

Can be expressed as..

1xa = 2xb 3xb = 1xc

Here is where the problem is..

Parent ices in algebra is used as a separator containing a formula within, to be solved before applying it to the solution. There is no mathematical function shown how to apply the result derived from solving the solution within the parent ices to a. With out a divisor or multiplier it could be c*a, c/a, c+a, or c-a

If we drop the variables we get…

A = 2
B = 1 therefore
C = 3

When no function is placed between two numbers they are usually are multiplied leaving us with …

What does c x a = ?

Replacing the variables…

What does 3 x 2 = ?

The answer is 6

If a fractional sign was used such as…

What does c/a = ?

Then you get a different answer. I believe a fractional sign was intended and that answer is…

3/2 or 1 1/2

i don't know, it's too early!

b=1/3c, c=1/3b
a=2b, b=a/2
c=(3/2)a, a=(2/3)c

c(a)=1/3b*2b= 2/3

I may be as wrong as 2 + 2 = 5, but I went for 12. I just took a quick guess, but if I had taken the time to sit down with a calculator and/or pen and paper, I probably would've answered you correctly.

24 if b=2. But b probably isn't 2. Sigh.

2/3? I haven't a clue.

What is the actual answer anyhow?

um, 6b^2?

isnt there supposed to be a constant somewhere in there in the equation?

I noticed that too. a*c depends on what they are. aren't the parentheses supposed to mean multiplied? There's no way of knowing by the rest of it exactly what a and c are.

24. I actually don't know, but there wasn't an option for that.

According to my calculations it is 2/3.

> b=1/3c, c=1/3b
> a=2b, b=a/2
> c=(3/2)a, a=(2/3)c
>
> c(a)=1/3b*2b= 2/3

On your first line you have b=1/3c, c=1/3b how can that be? How can they both be 1/3 of each other?

Let me demonstrate: If b=1/3c, (3c)b=1, bc=1/3, ... b=1/(3c) and c=1/(3b)

Lets try it, say b=3... then c=1/9. Let's test the other equation... if c=1/9, b=1/(3*(1/9)), b=1/(3/9), b-1/(1/3), b=3. That works.

Lets try another value, b=2... c=1/(3*2), c=1/6, and testing the other equation... b=1/(3c), b=1/(3*(1/6)), b=1/(3/6), b=1/(1/2), b=2. Yep, that checks too.

Saying b=1/3c & c=1/3b is NOT the same as saying b=(1/3)*c & c=(1/3)*b. They are not 1/3 of each other.
Instead, they form a b*c teeter-totter where either variable can take the gain to keep up with the constant. It's kind of counter-intuitive.

I don't know, but if I divide c by a I get 1.5

Cool, that's what I said!! Wow, never thought I was good at Maths but there you go.
I like your surveys by the way, I'm starting to be able to distinguish them from others cos of their quirkiness

Not on the amount of sleep I've had...

I hate math, but I am going to guess 1/6.

Thanks.

It's great to hear they are enjoyed.

Are we doing your algebra homework for you?

"Excuse me, why is your homework always two weeks late?"

Happy Birthday!

Hey, thanks. Do you keep a calendar or something? Oh, hmm, it's only an hour away. I made plans for a movie date tomorrow, forgetting it was even my birthday. That's part of my strategy for staying 28 eternally. Ah, I see this birthday flag thing now.

What you say of cats in your profile isn't at all true. My cat swings a claw at me as I pass his cat tree, has taken things I've set on the bed, has told me he's hungry then not eaten, and for all I know, talks about me behind my back with his brother.

You're welcome! It's a little thing bill added that's triggered by your user profile. What movie are planning to see? As to the cats profile, I guess I've been lucky. I've never had one of my cats take a swipe at me and since I tend to own only one cat at a time, they don't have anyone to gossip and say things behind my back to. However, my kitty has stolen my chair and only permits me to sit in it occasionally. She refuses to give it back even though I've asked nicely. I did own a Himalayan cat named Dove that would beg and beg and when you finally gave in and gave her a little bit (usually she begged for roast beef or steak-she was very fussy what she begged for), she would sniff it and then walk away.

I don't usually have homework......... and actually I was pretty good about turning it in on time. Did you mean to ask somebody else this?

Planning to see 'Finding Neverland'. My cats not outright malicious, just pesky. I wrastle with the cats, so I'm subject to the same instigations as his brother.

I was joking. That quote was what a teacher might say to the survey creator who was turning in assignments two weeks late, waiting for surveys to pass qualification and people to converge on votes for answers, before actually handing in homework.

The comment/joke was to you because you suggested the idea that this survey was for homework purposes.

I think my cat would just look at me as it I were crazed if I tried to wrastle with her. She's the laziest creature on the planet! We're planning to rent "Finding Neverland" when we go to the video store again...it looks great. With my bad vision I seldom see movies at the theater any longer, but wait for them to come out on DVD/VHS where I can watch them with more ease.

I'm lucky, glasses correct my vision to 20:13, quite sharp, and i can still legally drive without them.

Alas, Neverland isn't playing at the Majestic Crest in Westwood, CA anymore. I've never been to that theater, but doing some research, it does seem to be the inspiration for the Jim Carrey movie. It's a single screen $4 Million theater with stars on the ceiling, a deco neon facade, and the owner sells tickets, runs the projector, and has raffles. He got in the business after WWII.

yeah, I got it somewhat after I said that. It was probably due the day that the survey was submitted.

We had a nice theater like that in Eugene, but no more. When the McDonald was still open it has a balcony, velvet draperies, etc. I don't know old it is, but I went there as a child and it had been open for years at that time. It closed several years ago after showing it's final movie, which was "Castaway". I miss it because it had the cozy ambience you don't find in a multi-plex. As to my vision, I was diagnosed with myopic degeneration in my left eye a couple of years ago and since then have lost my peripheral vision in that eye. There is no treatment and I will eventually lose all my vision in that eye. It's not something I look forward to. Basically my right eye does most of the work.

I'm a real stereo-optics buff and art major. I'd be quite bummed to lose my vision. I went to one theater that still had an organ for accompanying silint movies. i love old art-deco theaters.

We do have an "art-house" theater called The Bijou and it's a bit art deco, but that's mainly because it used to be a funeral parlor. It's reputed to be haunted by a former mortician and has a resident female kitty named Boo who weighs over 30 lbs! She is huge! It's a real adventure even going to the ladies room. You have to go to the back door and go outside and then through a series of doors which give you the feeling of going through a series of catacombs. It's kind of creepy.

Huh, interesting.

There was a recent article in a local paper where some interesting images were caught by some people investigating the hauntings.

Hell if I know, I can't understand the QUESTION, let alone the answers!

Not many math experts here.
I took the formula to be asking for c * a
a=2b b=1/3c so, if a=2b then putting 'a' into terms of 'b' and 'c' would be a = 2*(1/3c)

so then for c * a, it would be c * 2(1/3c), or 2/3. Clear as mud, right?

You don't say! Want that with yogurt or blue cheese?

b=1/3c, c=1/3b
a=2b, b=a/2
c=(3/2)a, a=(2/3)c

c(a)=1/3b*2b= 2/3

Kristal, are YOU our resident math major? I sure hope so, I did super in school but math was my worst subject. I only liked geometry after I started playing POOL but it was Physics that made math real for me.

Now, at least I remember which hand to use for what fingers I need. If toes are involved, then it's calculator time!

Let me demonstrate: If b=1/3c, (3c)b=1, bc=1/3, ... b=1/(3c) and c=1/(3b)

Lets try it, say b=3... then c=1/9. Let's test the other equation... if c=1/9, b=1/(3*(1/9)), b=1/(3/9), b-1/(1/3), b=3. That works.

Lets try another value, b=2... c=1/(3*2), c=1/6, and testing the other equation... b=1/(3c), b=1/(3*(1/6)), b=1/(3/6), b=1/(1/2), b=2. Yep, that checks too.

Saying b=1/3c & c=1/3b is NOT the same as saying b=(1/3)*c & c=(1/3)*b. They are not 1/3 of each other.
Instead, they form a b*c teeter-totter where either variable can take the gain to keep up with the constant. It's kind of counter-intuitive.

Say again, over? .... no, on 2nd thought... don't... my mind is boggled already. My mother was a math whiz, but it sure skipped a generation!

Katie, my eyes are f'ed, too... I mean I can see, but doing computer stuff would be impossible without my glasses. And both eyes are so very different, I can't even buy a +3 at the grocery store! I don't think they have +4's.

Kristal, my Grandmother played the piano for silent movies.

What is a +3/+4? Are those reading glasses? You should see the lenses on my glasses...they are a thick as the bottom of a glass Coke bottle. My left eye is far worse than my right eye.

If c = 1 then the answer is 2/3. If c doesn't = 1, the answer is going to be something else.

If a = 2b and b = 1/3c, what does (c)a equal?

If c =1, then b = 1/3 and a = 2/3. 2/3 * 1 = 2/3

BUT

If c = 3, then b = 1 and a = 2. 2*3 = 6

if you change c(a) to c/a then it will always be 2/3.

i think

yep, those are the grocery store variety reading glasses. My friend HAD coke bottles since 2nd grade, (he's the bass player in my pix) and just had lasik done and so far so good... he say us clear and sharp for the very first time... he was real lucky his eyes qualified for the surgery, he might hafta go back for some tweaking... Alice had it years ago and now only needs reading glasses for up close... I'd love to have it done but I can't afford it

Got a sharp knife I can borrow so I can cut some fingers at the knuckles to have fractions?

Lasik isn't an option for me for a number of reasons even if I could afford it.

ya, I figured you'd be out of their circle... sorry about your sight, I had a friend that has Macular Degeneration in her family... lost track of her back in the mid 70's but she's probably blind by now.

That must have been a blast. I imagine by the end of a long run she had fancy arpeggios to represent each little thought a character might have.

Thanks! My problem is myopic degeneration which is a subgroup of macular degeneration. It's pretty uncommon...roughly only 7% in the U.S. have it and there is no treatment or cure. One of my favorite authors has macular degeneration, namely Stephen King.

my mother was even better at piano (and later the organ) than grama... mother's piano teacher told us she was the best student she ever had... and this was when the lady was in her 90's when she told us that. My mother was by far the smartest and most wonderful person I ever knew... she graduated U/W .1 off straight A's... she was a registered Dietician then later the exec sect'ry to the Chief of Staff of a naval base (civil service)
I grew up surrounded with music and I remember grama doing the "thriller runs" on the piano... I had a great childhood

Best piano student could mean anything. Playing for silent movies, though possibly done with a score, can also suggest an ability to do improv. Late nights on PBS is a show called Classic Arts Showcase, sort of the MTV/VH! of classical music (no commercials either), theater, art animation, pretty much any performance arts from the corners of the globe. Some times you get orchestras performing to silent movies there. I practice my guitar (more of an electric cello) by playing along to whatevers on tv at the moment. You get to a point where you can pretty much 'converse' through music.

that's what my mom could do... she played everything, but when she hear Scott Joplin in the Sting, she REALLY like that... I remember "boogie woogie" from the 50's... and "stardust" is my all time favorite tune... she had the most haunting rendition of Clair d' Lune, and Malaguena was one of my favorites, too... I use to sit and turn pages for her if she needed to have the music.

I like those genres, things that feed into jazzy be-bop lounge and surf. I'm also into bluegrass, hindu, and microtonal techno. My own music sounds like several instruments playing together in just one take. I just got some really haunty Lunaire german-expressionist chamber jazz. Again, I'm making a portable guitar studio for my tandem bicycle. This version is motorized, with a gas motor using the electric motor to charge the batteries for amp and effects.

My friend Alice gets back from Nashville tonight. Will be exciting to hear how the studio work went... wanted some studio to go with the live for our next cd... and I LOVE bluegrass... I remember one of our bluegrass groups, the banjo player had Skrugg's Pegs and I just LOVE them! Alice has 4 electrics and her main acoustic, a big Martin,( D-28, I think, but I could be wrong. ) She plays a lot of instruments, but it's mainly guitars now. It's so awesome living with such talent. She is easily the most dynamic person I have ever known. I am so fortunate to be a part of her band. It's really an eye opener to know the innards of the music biz from this side!

I will, for sure, let you know when Alice has a tour down your way. Our pedal steel player, Charlie Wallace, lives San Diego area, so Alice will get down there sometime.

eek!

My style is mostly like a mix of pedal steel /veena (except with fingers so I can independently slide chord components) and tappistry (tapping notes with both hands at once, so fas it blurs into a wall of melodic chordal sound). So what do you play (instrument and genre), and where? My family lives in Bellingham.

My own sound is like Fripp, Dr. Seuss (as I imagine he'd play an instrument), and that range of bluegrass, hindu, surf, techno and Velvet Underground sor of rock. I've really got to get around to posting my music, but my current site's out of space already. http://www.ereiam.com

Sorry, but I suck at math.
