Yes. In 12 months his $1,000 would be worth =$1,060.62.

Rich    =   20000(1.01625)^40           40 time periods of 1.625% interest

Joe     =    20000(1.0027083)^240     240 time periods of .27083% interest

Dan   =    20000 e^(.0325 x 20)

If you calculate these you find that Dan is the winner !

You need to save =$244.29 every month for 18 months @ 3.25% compounded monthly.

thank you!!

Rich will have =$38,111.18

Joe will have =$38,277.17

Dan will have=$38,310.82

She starts with 6 rows of 'x' chairs with 3 remainder     6x + 3   chairs       if she adds 11 more   (6x+3) + 11   she can get 8 rows of 'x' chairs   8x

so:      (6x+3) + 11 = 8x   solve for 'x'   the number of chairs in each row

6x + 14 = 8x

14 = 2x

x = 7    is the number of chairs in each row

sqrt3 (x) = cuberoot (x)  =  x ^(1/3)

sqrt(x)    =                          x^(1/2)

From laws of exponents     x^(1/3)  *  x^(1/2)   =    x^ (1/3 + 1/2) =  x^ (5/6)      

Quadratic FORMULA  is     x =   (   -b +- sqrt (b^2 - 4ac) )  /  2a

Once you get your quadratic EQUATION into the form     a x^2  +  b x  + c = 0    you can substitute the values for 'a' 'b' and 'c' into the FORMULA to find the values of 'x' that solve the equation! 

(2kg)(450J/(KG x K)) (5 K) Please Help!!

Step 2 of 2 Preview Answer

This is dimensional analysis....it can often help you find the correct answer in the correct units for very long or complex equations (there are some that are MUCH MUCH more complex than this in engineering and physics !)    Lets just drop the numbers first to demonstrate what happens:

kg  x  j/(kg k)  x k      k is degrees kelvin   j is joules   

You should be able to see that the 'kg' s will cancel out   and the 'k' s will cancel out and you are left with only j   joules   after you multiply all of the numbers together

Now lets do the math:

2 x 450 x 5  =  4500      we already know that the unit is j     so the answer is 4500 j    or 4500 joules

It's $36.

@CPhill can you explain 2 i don't understand what you meant  

23/10= 2.3 pieces per hour (on average)

2.3 x 5 = 11.5 pieces per hour (after magic moss)

11.5 x 5= 57.5 pieces of wood for the five hours after magic moss.

  57.5

+23.0      (23 is the amount of wood for the next 10 hours)

_____

  80.5 pieces of wood in the 15 hours after magic moss!  

Thanks!! That was a really fun problem!

(Sorry if I'm wrong)

2/3+3/4+1/6    get a common denominator  = 12

2/3  =  8/12

3/4 = 9/12

1/6 = 2/12

So

8/12 + 9/12 + 2/12   =  19/12  = 1 + 7/12

29.00*900  = 26100
