Hey...you passed kitty<3...!!!   Rom had better look out........Hey, maybe I'd better look out  !!!!

P.S.......your answers are always very good......ND

We need to set this up as an algebra problem.

But before we do that, we need to make sure all our numbers are in the same base, so well convert all the numbers to yards, becuase that's what they sell the concrete in.

12 feet = 4 yards

6 inches = 1/6 yards

And we know that width*length*height @ $98 per yard = 108.89

So width*length*height*98=108.89

We don't know the width, so let's call this "x"

x*4*1/6*98=108.89

x*4/6*98=108.89

x*392/6=108.89

x*65.3333=108.89          ---Divide both sides by 65.3333

x = 1.66666

x = 1 and 2/3 yards               ---Change to feet by multiplying the right side by 3

x = 5 feet

So the width of the driveway is 5 feet.

Good job, ND......yep, this problem is more about "eliminating" the wrong choices, isn't it???

Nah, don't worry about it.

I just thought I'd let you know what it looks like for us. :)

I'm not seeing any pics, ND........!!!!!

Maybe there's something wrong with MY computer !!!!

Sorry....I ddidn't realize it was displaying like that for you guys....apologies

AH....I see it now....no wonder you guys were having trouble!!!!

I'm going to say, "the volume of each tank."

I say this because it said that the width and height of these tanks are (x-7)

So together the width and height can be expressed as (x-7)²

The length is 8 inches more than the width/height, so this can be expressed as (x+1)

The 8 on the outside is just telling you to multiply the width/height/length by 8 to get the volume of all 8 tanks.

Also, you don't get surface area when you multiply width/height/length, so that rules out the other two options.

CPhill, I think the problem was that some of the fractions mari used are displayed as pictures for whatever reason.

I'm having this same problem. This is what the question looks like to me:

Our formula for the area of a circle is

A=(pi)r²

I'm going to say, "Step 1, because incorrect signs have been used."

Here's my reasoning:

2x - 1/4 of (12x + 4) = 3           ---"of" means to multiply here

2x - 1/4*(12x+4) = 3                ---We do need to distribute the negative sign out. This is the same thing as

2x + (-1/4)*(12x+4) = 3

2x + (-3x -1) = 3

-x -1 = 3

x = 4

24 (1.09) = 26.16 mpg

Let's take this by parts

log3² + log 16^1/2 = lg 9 + log 4  = log (9*4)  = log(36)  .... and.....

[log 12 - log 2]   =  log (12/2)  = log (6)

So, the first fraction becomes.....log(36)/log(6) = log(6)² / log(6) = 2log(6)/log(6) = 2

And the numerator of the second fraction is.......

[2 - log 25 + 2log8] = ] 2 - log25 + log 8² ] = [2 - log25 + log64]

Notice, in terms of logs, that 2 can be written as log 100

So we have..

[log100- log25 + log 64] = [ log (100/25) + log64] = [log(4) + log (64)] =

log (4 * 64) = log(256) = log(16)² = 2log(16)

And the denominator is....

log ³√16 = log 16 ^(1/3) = (1/3) log 16

And the second fraction becomes...

[2log(16)] / [(1/3)log(16)]  = 2/(1/3) = 6

So...combining the result of the first fraction and the second fraction, we have

2 + 6  = 8

And there you go.......

ln(1) is 0  (in fact log_b(1) is zero, whatever the base, b, is because b⁰ = 1; and when log_b(x)=y, this means, by definition, that b^y = x.  In your case b = e, x = 1 and y = 0).  You should be able to do the rest.

The ln of 1 = 0

So, 0 - 7  = -7

no im not!i swear i gave no on five points!

Lieing just like ds huh?

No Zegroes not at all , i gave no one 5 points!i think the moderators along with users gave her!

Oh so you give kitty 5 points but not your best friend zegroes!I see how it is im pullin out the sexist case also!

We're just adding the x coordinates and the y coordinates to get the result...so we have

(10 + 11, 11 + (- 5))  =  (21, 6) = g + h

Think of it this way...If we are plotting the point (2,3), aren't we really just adding 2 and 3 to the coordinates of the origin, (0, 0) ???

Hope that helps......

The area is just length* width = 2√2 square units.  Because √2 is irrational (i.e. cannot be represented exactly by the ratio of two whole numbers) then so is the area.
