Question 1: 

On a particular day, the following appliances are used for the times indicated: a 1600-W coffee maker, 12 min, and a 1100-W microwave oven, 4.9 min. With these power requirements, find how much it costs to use these appliances at an electrical cost of 6¢ per kWh. (Do not round your final answer. Fractional cent values are acceptable.)

1600W for 12 minutes is

1.6KW for  12/60 hours

which is  1.6*12/60  KW hours = 0.32KW hours

At 6c/KWh that is

0.32*6=$1.92

Now you can work out the microwave oen yourself. :)

slope = change in y / change in x  =   7.8 / 2.4   =  3.25  =  3 + 1/4  = 13/4

Can you please tell me how you got 17.5 in details? Step by step?

25 *  $10.10  =

25 * $10   = $250    +    25 * .10  =  $2.50      =    $252.50

Sin^-1  and  Arcsin are the same thing.........the inverse sine

Use the clarks table..natural tangents answer is 39.8°.

We have the point (5,2) on the graph

If the slope is  3.1,  f(10)  =  (10, 17.5)  

If the slope is meant to be 3:1, then f(10)  =  (10, 17)

No, 6 + 6 is not equal to 26. lol

hello?

Thanks.

There you go :) I gave 5 points to each answer in this post (20 points total unless you reply to this which will then be 25)

A   =    A *  1

B                B

FV =$5707: N=25: I=0.08:  PMT=?

PMT=$78.06

Thank you the Math Guy!

Just finished "Anne of Green Gables" not too long ago, hectictar.....very good!!!

"The Count of Monte Cristo" is also a fav of mine, TheMathGuy.......

First, multiply the first rational expression by the reciprocal of the second rational expression.

Factor by taking out the GCF and using FOIL method.

Set the denominators equal to zero.

I'm personally a huge fan of Shakespeare's tragedies. you know, Hamlet, Macbeth, Romeo and Juliet. if you can get past the language and the Iambic pentameter then they make for really great reads. also, the Count of Monte Cristo is excellent. (if you can find the unabridged version it's even better.) without giving away too much, it's about a guy who's betrayed by his friends and is taken to a prison where an old man teaches him a lot of knowledge. (it takes place way in the past by the way) he escapes and takes revenge on everyone who betrayed him.

I don't read very much but a few of my favorites are Christy by Catherine Marshall, the entire Anne of Green Gables series (My favorite was Anne of the Island), and I know this is a silly one but I love the Diary of a Wimpy Kid series.

1/2 x 2 = 1

secA   =  r /x

r = √ [ x^2 + y^2]  = √ [ (7^2) + (–4^2) ]  = √ 65

So

sec A  =  √ 65 / 7

i have seen it in a store, thats doubled with how tiny the words usually are. 

Les Miserables  is about 1500 pages...[more or less]...!!!!

I have read a 600 paged book called "Deeper"

The first  and last ones may be a little "advanced" for you, MJ

The second  wouldn't.....you can read the unabridged version here :

Caution.....it is L O N G  !!!!!!!......maybe a better Summer reading book.....also....the abridged version is probably just as good....but....you  will have to seek that  out......!!!!!

Well, thank you, I'm actually 12, your right. thanks, and I do read a ton, so It helps a little, just another thing I'm good at. :)

I need to qualify my comments: but if you are the author, and from your posts, I estimate your age is between 12 and 14, then your writing is very good. This kind of writing usually only comes from very practiced high school students.
