Yes I do, and sorry about not mentioning the fact that this is answered. I will wait one or two more days, and see if anyone comes up with an answer :)

hint: similar triangles

Yes it does, I had edited it, at least I thought i had but I guess something went wrong.  

Thanks for your observation  

I always start by remembering that    \(log_{10}100=2\)

so if

\(y=\log_{\sqrt[3]{5}}125\\ then\\ \left(\sqrt[3]{5}\right)^y=125\\ (5^{1/3})^y=15^3\\ \)

You can finish it.

Doesn't it go through the points (1,-3) and (4, -4)?

Let x be his original amount of money.

After spending 25%, he still has 75%, or (3/4)x.

1/5 of the remaining = still having 4/5

(3/4)x*(4/5) = 240

(3/5)x = 240

x = 400.

could be the correct answer 

-3x + 4(5x - 31) = -37

-3x + 20x - 124 = -37

17x = 87

(x, y) = \(({87 \over 17}, -{92 \over 17})\)

dont think ur answer is correct....

First you have to find the equation of the line.

Hint:  it goes through (1,-4)  and  (4,-5)

I agree SparlingWater2, this is a tricky problem.

I made an interactive pic here.  (just because I like drawing pics with GeoGebra)

Hi SparklingWater2

If it took you hours to solve it, then I guess you already have the answers.

So... you have posted it as an interest question?

That is perfectly fine but you should make it very clear that that is what you have done.

How many liters of pure water must be added to how many liters of a 25% bleach solution to make 12 liters of a 20% bleach solution?

Hello Guest!

Wie viele Liter reines Wasser müssen zu wie vielen Litern einer 25%igen Bleichlösung hinzugefügt werden, um 12 Liter einer 20%igen Bleichlösung herzustellen?

\((12l-x)\cdot 0.25=12l\cdot 0.20\\ 12l\cdot0.25-0.25x=2.4l\ |\ +0.25x-2.4l\\ 3l-2.4l=0.25x\ |\ :0.25\\ \dfrac{0.6l}{0.25}=x\)

\(x=2.4l\)

2.4 liters of pure water must be added to 9.6 liters of a 25% bleach solution to make 12 liters of a 20% bleach solution.

Recall that an angle is obtuse if and only if it is between 90 degrees and 180 degrees. You should be able to get it from here, ask if you have any further questions.

The two horizontal lines in the diagram below are parallel. We are also given the measure of one angle in the diagram. Find the value of c.

Hello Guest!

d = 120°  alternating angles at parallels

c = 180°- d = 180° - 120°

c = 60°

That's wrong

.80 x    is amount after spending 20%

3/8 * .8x   is amount after spending 5/8 remaiing

3/8 * .8x + 90    =   3/2 x

.3x +90 = 3/2 x

90 =  1.5x - .3x

90 = 1.2x

75 = x

n = 8.

Consider rhombus ABCD, with side length 6.  This is rolled to form a cylinder of volume 27/2 by taping AD to BC.  What is sin BAD?

sin BAD = sqrt(2)/3

Geometric series    a1 = 600       r = 1.15      sum =?

S =   a1 ( rⁿ -1) / ( r-1)

  =  600 ( 1.15⁵ -1) / ( 1.15 -1) = 4045.43

There are 6*3! = 36 ways for all three people to sit together, and 8! without any restrictions.  So by complementary counting, the answer is 8! - 36 = 40284.

Show work plz!
