6 X 60=360 minutes in total

360/15=24 minutes per day she will need to spend.

What is a unit rate?

In your case, what is most important for you to understand is this: If you went into a store and bought 5 sticks of gum for $3.00, what is the unit rate in dollars and cents per 1 stick of gum?

So you have to divide $3.00/5=.60 cents, which the cost of one stick of gum, or the "unit rate" in this case.

2/3 of the people who are in a room are sitting on 3/4 of the chairs that there is. The rest of the people are standing. If there are 6 empty chairs, how many people are in the room?

Let P=number of people in the room

Let C=number of chairs in the room

2/3P=3/4C

C - 3/4C=6

1/4C=6

C=24 number of chairs in the room.

2/3P=18

P=27 number of people in the room

Thanks

I also had a problem with uploading images earlier today (and still have!).

The Uploading tab produces a blank page.

The area of this triangle may be found using Heron's formula which says:

\(A=\sqrt{s(s-a)(s-b)(s-c)}\)

where A = area, a, b and c = side lengths, s = semi-perimeter = (a+b+c)/2

You can plug in the numbers.

In math, the unit rate is a comparison of two different quantities when they are combined together. Discover the definition of the unit rate in math with tips from a mathematics tutor in this free video on math lessons. -Wikipedia

Let p = number of people and c = number of chairs.

If 3/4 of the chairs are filled then  (1/4)c = 6  so c = 24

 We are told that 2p/3 = 3c/4  so 2p/3 = 3*24/4   or 2p/3 = 18  so p = 3*18/2 or p = 27

There are 27 people in the room.           

Thanks anonymous4338.  I read it wrong.  I will edit my answer.  :/    

ok I fixed mine, it is ACB just like anonymous4338 and buubleman already found. 

Great work you two    

 if you say celia's statement is true this mean she can not be last

Next we have Ana, if her statement is false this means that she has to be the oldest so she is first

then we come to Beatriz if her statement is false this mean she has to be the youngest so she is last

The order follows as ACB, I think this does not break any rules. So i think this is the correct order Correct me if i'm wrong!

The Answer to Life, The Universe, and Everything, according to Google is 42.

Math is infinitely awesome.

Melody:

I'm looking at your answer and I'm not sure if it's right.

You said that...

Ana is oldest, then Beatriz, and the youngest is Celia

This contradicts all three statements that buubleman provided.

In your statement,

Beatriz is NOT oldest...

Ana IS oldest...

and Celia IS the youngest.

However, if I'm correct, Statement 3: Celia is not the youngest, is true, then that would mean Ana not being oldest would be false and Beatriz being oldest has to be false.

To do that, you could have Ana being oldest, Celia in the middle, and Beatriz youngest.

Is Ana oldest, Celia next, and Beatriz youngest correct, Buubleman?

Thank you everyone!

Agree with Anon4338 and have made changes to reflect that answer !

OK.....if only ONE is true, the other two must be FALSE.

Let's call them 1   2   3 

If 1  then NOT 2  and NOT 3  won't work because it would mean B and A ae BOTH the oldest.

If  2  Then NOT 1  and NOT 3    won't work because IF ana is not the oldest she is either middle or youngest, NOT3 says Celia is youngest so Ana would be middle BUT that would make NOT 1   untrue

If 3 is t true then  NOT 1 and NOT 2       would not work      as  A C B       Ana is the oldest=NOT2  Celia IS  NOT the youngest=3 which leaves one position for B which is OK because NOT1= Beatrice is NOT the oldest

ACB is the answer.

Very nice, heureka.......!!!!

Hi, Guest.

If I'm interpreting this correctly, you want the surface area of this triangle in square feet!

If so, then could you please specify which measurements are which?

Thanks!

This is identical as my last question but i missed one thing.

Ana, Beatriz and Celia are 3 kids they say 3 statements ONLY one of these statements are true.

Beatriz is the oldest     Ana is not the oldest     Celia is not the youngest

Put the 3 kids in order from oldest to youngest! 

Lets look at each one.

Say Beariz is the oldest it true.  

Then Ana is not the oldest is also true but only one statement can be true SO

Beatriz is NOT the oldest

Say Ana is NOT the oldest is true.

We know that Beatriz is not the oldest,  If neither of those 2 are the oldest then Celia must be the oldest.

BUT this would mean that statement 2 and statement 3 are both true and that is not allowed.

Therefore Ana is the oldest

Edits are in red

Say Celia is not the youngest. then Ana is the oldest and Beatriz must be the youngest

Ana is oldest, then Celia , and the youngest is Beatriz

Hi DS

I have not had any problems uploading images.  Are you sure you are doing it correctly?

:D.

Thank you very much!
