YOUR QUESTION:the length if Laurie's rectangular swimming pool is triple the width. The pool covers an area of 192m2

A) if Laurie swims across the diagonal and back, how far does she travel? (I know the answer to this a), it should be 151.8 right?)

B) at the same time Laurie starts swimming, her cat walks one lap around the edge of the pool. Laurie can swim 3/4 as fast as her cat can walk. Who will return to the starting point first? Justify your answer. (Now, I got confused here.....I know time=distance over speed, but what's the speed?)

since you seem to have this for the most part im just gonna help you with the speed
if Laurie can only swim 3/4ths as fast as her cat walks then you can represent that with 3/4 x

i hope that helps. pm me if you need clarification :)

So @wingz how would I set up the equation then? Ouo and how to set it up for the answer of who would get there first?

YOUR QUESTION:Which "theme" does Sociology study - nurture or nature? Explain why.

Some may argue that we are who we are based on genetics and hormones. If we look at it from this perspective, our temperament, talents, physical features etc. is set before our birth, which all in turn will affect how we behave. There was a study conducted in 1968 that looked at the effect nature has on twins. There were five pairs of twins who were made the subjects of this study. One of the pairs was from a mother who was mentally ill, who had two identical twin daughters. The twins were both put up for adoption. Both of the girls were raised in different households, and were separated. The adoptive parents were only told that the child they were adopting was participating in an ongoing study. The twins, Elyse Schein and Paula Bernstein, reunited with each other at age 35. The looked alike, and also behaved alike, using the same facial expressions, etc. The twins had not met before, and were raised in completely different households, so one of the only things they had in common was nature - genetics. The fact that they behaved alike despite being raised differently shows that genetics does indeed play an important role in human behavior.
Here's an article about this study if you're interested.

On the other hand, nurture also plays in important role in how we behave. Nurture is the affect society has on us. Religion, social class, gender - all these are things that could potentially affect how we behave. Aristotle, a Greek philosopher, theorized that we are not born with knowledge - our knowledge is acquired from experience, as we would not be able to use logic or reasoning if we were born with all the knowledge we would ever have from the start of our lives. The knowledge that we have now is partially based on our experiences. If you were raised in poverty, your experiences would be very different from if you were raised in a wealthy household. Obviously there may be exceptions to this, but the point is that our experiences shape us in a way that we are all unique: we may have different likes and dislikes, define "right" and "wrong" differently in some instances, and this will all affect how we behave.

In short, both are what sociology studies, as both do have an impact on how we behave and how we interact with each other.
It's late where I am, so there may be a few mistakes here and there, but I'll re-read this later on and make amendments if there's something terribly wrong I've written ^^

Are you sure the answer to a) is 151.8? I got 50.6m:
Let L be the length and W be the width of the pool.
L*W = 3W*W = 192
W^2 = 192/3
W = 8

L*8 = 192
L = 24

Diagonal length:
2*√(L^2 + W^2)
= 2*√(24^2 + 8^2)
= 2*√(640)
= 50.6m

For b), calculate the perimeter of the pool. That would be the amount of meters the cat walks. Multiply the perimeter by 3/4, and that would be the amount of meters Laurie needs to swim in the same amount of time. Compare the answers, and you should be able to figure out who gets to the starting point first. (Whoever walks/swims more in that amount of time will get to the starting point first)

YOUR QUESTION:Which "theme" does Sociology study - nurture or nature? Explain why.

I'm not sure what this question means exactly
but I'd say nurture
My soc teacher says that sociologists believe there is a social action that causes a personal effect
like society forces something onto people which causes people to have a personal effect

say, a man joins a gang
in sociology, we'd look at the social reasons why
maybe he's a football star.
what is one socially feminine thing that ties in with football?
ballet.
say he's getting bullied for taking ballet, even though it's helping him in football
he feels weak, he feels vulnerable
he joins a gang because he feels weak bc society is pushing stuff on him
we are taught ballet is 'only for girls'
we are brought up this way
it's 'nurtured' into us

idk if I'm making sense orz

@svel, I got a totally different answer.

The area of the pool is 192m2, and the length is tripled the width, so
3w=L
And the equation would be
3w+w=192
4w=192
W=48
So length would be 144 (48×3)

So now, you have the side lengths, you can use pythageron's theorem to calculate the diagonal.
A2+b2=c2
48^2+144^2=c^2
2304+20736=c^2
23040=c^2

So c= 151.78.... Of rounded to 151.8
Then, multiply it by 2
So it is 303.6 m of the two diagolas back and forth.
Could be wrong!!!

But the area (not perimeter) of the pool is 192, so you would have to multiply 3w and w, not add.

^^zou are correct. In that case, I am wrong. I misread, forgive me ouo

YOUR QUESTION:the length if Laurie's rectangular swimming pool is triple the width. The pool covers an area of 192m2

A) if Laurie swims across the diagonal and back, how far does she travel? (I know the answer to this a), it should be 151.8 right?)

B) at the same time Laurie starts swimming, her cat walks one lap around the edge of the pool. Laurie can swim 3/4 as fast as her cat can walk. Who will return to the starting point first? Justify your answer. (Now, I got confused here.....I know time=distance over speed, but what's the speed?)

Alright, because there's a lot of confusion, I decided to attempt the problem myself and explain it as clearly as possible.

Since the length of the pool is three times the width, we get the equation L = 3w.

The equation for area is L x w = A, so we substitute in and we get:

3w x w = 192

Now we solve to find w.

3w^2 = 192 (Remember that ^2 is a way of writing "squared.")

w^2 = 64

w = + or - 8 (You may not have gotten into this yet, but basically every positive number has two square roots, since a negative times a negative is always positive. However, it is not possible for something real to have a negative width (how would it work?) so we disregard the negative solution.)

w = 8

Now, to find the length, we substitute back in to that first equation.

L = 3w
L = 3 x 8
L = 24

Now we use the Pythagorean Theorem to find the length of the diagonal. It's important to remember that this theorem only works for right triangles. We know that this one is a right triangle because all angles in a rectangle are right angles.

So, the theorem before substitution is:

a^2 + b^2 = c^2

In the Pythagorean Theorem, c is always the length of the hypotenuse (diagonal). The order of the other two sides doesn't matter.

8^2 + 64^2 = c^2
16 + 4096 = c^2
4112 = c^2
c = 64.1248781675

We would probably want to round this to 64.12 meters.

Then, we simply multiply by 2, since Laurie swims across the diagonal and then back, which equals 128.24 meters.

So, since word problems must be answered with a sentence, we get:

If Laurie swims across the diagonal and back, she will swim 128.24 meters.

As for the second question, I'm a bit of a dummy with speeds and such, but I can tell you that, like Svel said, the cat walks around the perimeter of the pool, so you would use this formula:

L + L + w + w = P

or

2L + 2w = P
