Good work !    

Who is Bro?

If you are going to comment on someone's input, you could at least make it clear, which input you are commenting on!

[ x (x)^1/3]^1/3

= \(\sqrt[9]{x^4}\)

I'm assuming 3 1/2 is a mixed fraction.

If you get confused with mixed fractions, you can always convert them to normal fractions like \(\frac{1}{2}\). 

\(3\frac{1}{2} \) converts to \(\frac{7}{2}\). You can find this by multiply the denominator(bottom of the fraction) by the integer part then adding the numerator(top of the fraction). You get \(3 \cdot 2 + 1 = 7\). Then divide that by the denominator or \(2\) to get \(\frac{7}{2}\). \(\frac{7}{2} \cdot 20 = 70\) because the \(2\) in the denominator cancels out with the \(2\) in the \(20\). Remember that \(20 = 2 \cdot 10\) which is why they cancel. 

\(70\) is your answer.

Use the distance formula between two points to calculate the distance....this is ONE SIDE of the square.....Multiply this times 4 for the perimeter.

how?

This question needs to be corrected!!!

Mary had $488 more than Rachel at first. After each girl spent the same amount of money at a shop, Rachel had  3/5 of her money left while Mary had 6/7 5/7 of her money left. How much money did they have left altogether? 

Mary had => 488 + x             Rachel had => x

After each girl spent the same amount of money, they were left with:

Mary => 5/7(488 + x)             Rachel => 2x/5

Amount of money each girl spent:

Mary => 2/7(488 + x)              Rachel => 2x/5

2/7(488 + x) = 2x/5

x = 1220

They had left altogether $ 1952

At LEAST 5    means  5  or 6  or 7   or 8  or   9  or 10  could have been Heads ....

10c5   + 10c6    + 10c7   + 10c8   + 10c9   + 10c10 = ______________

4/5 g   =   3/4 r       this is given.

re-arrange to   g = 15/16 r

then

(g - 105 )  / (r-102)  = 5/6 

g-105   =  5/6 (r-102)          sub in the red equation

15/16 r  - 105  = 5/6 r  - 85

r = 192     then using the red equation again  g = 180   for a total = 372 apples originally

     then he sold 105 + 102

         372 - ( 105+102) = 165 aplles left

There are ten players total ( does not matter that some are boys, some are girls)

   each must play 9 other players     10 * 9 = 90  games 

                                              BUT each game involves TWO players...so divide by 2 to get   45 games must be played

Alex, Bernard, and Calvin shared the cost of a present. The ratio of the amount

paid by Alex to the total amount paid by Bernard and Calvin was 2:5. The ratio

of the amount paid by Bernard to the total amount paid by Alex and Calvin was 

1:2. Bernard paid $20 more than Alex. How much was the cost of the present?

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Total cost of a present => x

Alex paid =>  2/5x

Bernard paid =>  x/2

(x/2) - (2/5x) = 20

x = 200          

x - (x/5 +36 + 5/8(x - x/5 - 36)) = 24

x = 125

90 C 2 ==4005 ways of picking 2 numbers out of 90

Of the 4005, there are 2,235 products that are divisible by 3.

Therefore, the probability is ==2235 / 4005==149 / 267

Chuckie can ALMOST get 13 kits from each piece of 8 foot stock...ALMOST

   8 ft = 96 inches

        to get 8 kits would require 7 cuts       7 cuts means  7/16 waste added to the 7 3/8 required for the 13 kits

                    13 kits * 7 3/8  + 7/16 = 96.3125     Sooooo close....

So Chuckie can onle get 12 kits from each 8 ft stock

    500 kits  *   ( piece stock )/12kits = ~~ 42 pieces of stock

ok it is answered.
