If this diagram is not drawn to scale, then 'x' could be 45 degrees.

Yeah I agree, please be specific richie7593 

so we see that it increases by 27 and the original number is 50 so it is 27*100=2700 and then we divide by 50 to get 2700/50=54

so our final answer is 54

1 / M   +  1/ S  = 1/3

1/5     + 1/S   = 1/3      solve for S   the time alone for Sydney to clean the house

Another way (when you have TWO people)

S * M / (S+M) = 3

5S = 3S + 15

2S = 15

s = 7.5 hr

People - hours per wall   =   5 p 1/3 hr / 5 w =  5/15  p-h / w

5 p- h / 15 w    *  9 w  /  9 p  =   5/15 hr = 20 min

The equation for amount of work done is w=rth, where w represents the work done, r the rate, t the time, and h the number of people or things doing work.

So with the first sentence we have 5=r(20)(5), which simplifies to 5=100r, so r=1/20. Now we substitute this into the equation for our second sentence.

9=(1/20)(t)(9)

9=9/20t

t=20 minutes.

um it looks like something's missing from your question. Or is this just a troll post?

great job LoryLullic :D

i dont know much latex, so i will try to explain without it.

If you subtract 50 percent from 77 percent, its 27 percent. We can say that 50 percent IS 100 percent. 77 would then inscrease by 27 percent, but since 50 percent is half of 100 percent, we need to multiply by two, so we get a 54 percent inscrease

(How did i do :D)

Find the unit rate of these two deals to find the cheaper one.

$5 per 3 cans = $1 2/3 (or $5/3) per can, because you divide by the amount of the unit (which are cans).

$14 per 9 cans = $1 5/9 (or $14/9) per can.

1 2/3 is about 1.67, and 1 5/9 is about 1.56, 1.56 < 1.67

Store B has the better deal

its 5.5 youll see the explaination when you get the soulution

ok that makes sense

% increase\(=\frac{(\text{final value minus initial value})}{\text{absolute value of the initial value}}\cdot 100\) And in this example: \(\frac{77-50=27}{\text{initial value}=50}=\frac{27}{50} \cdot100\)   

I'll leave it up to you to simplify \(\downarrow\) Hope this helps!

                                 Answer=\(\frac{27}{50} \cdot 100\)

the reason i posted this again was beacuse the answers wrong

That would still take 20 minutes.  

Sorry, Can't read your LaTex !.

[19^2006 + 11^2006 - 6^2006] mod 10^10 =2,350,090,786

In three years, Sandra will be 3x and Jason will be x. We also know that x+18=3x. Using these equations, x=9, and 3x=27. That means, in three years, Sandra will be 27. Two years ago, Sandra was 22 years old. Hope this helps! 

Would you tell me which bank that is?  The best rate I can find is 1.45%.
