√7 * √ [ 7 + 6] * √91 * √[ 91 + 6 ]  =

√7 * √ 13  *  √ 91  * √ 97   =

√ [ 7 * 13 ] *  √91  * √97

√ 91  * √91  *  √97  =

       91√97

WOW! I'm not sure it that's right, but THANKS!!!!!

Sorry I am not CPhill, but I will help :D

Start with 0, and go up to 9999.

0 divided by anything can't be a number, so 0 is not the answer.

Every whole number is divisible by 1.

2 should be in the hundreds place to make a small number.

MAKE SURE THE NUMBER IS EVEN.

You can put a 3 in the tens place, but you cannot use any other odd numbers.

We can't use 4, since 4 is not divisible by 3, or 5.

6 is the next number that works

Hence, 1236 is the smallest number divisible by its digits.

Hope this helped!

0.33333.....   =  1/3

0.83333.....  =      [ 83 - 8 ]  / 90   =  75/90  =  5/6

So

(1/3)  /  ( 5/6)   =   

(1/3) * ( 6/5)   =

6 / 15  =

2 /  5

I am not postive but maybe 102?

Assuming that all samples of 7 tiles have the same ratio of vowels / consonants....

Out  of  the 7 tiles, 3  are  vowels 

So....the  number  of tiles expected to be vowels out of 105  =  (3/7) (105)    = 45

The  side across from the 30° angle   =  (1/2) (hypotenuse)  = (1/2) (2√6)  = √6

The side across from the 60° angle =  (√3) ( side across from 30° angle)   = (√3)(√6)

Sum of leg lengths =     √6 ( 1  + √3)   cm   ≈    6.69 cm

We  have something like this

                                                                     26

                                                 like tea

               men                 33                

                                               don't like tea   

                                                                        7

90

                                                                       47

                                                like tea

          women                  57

                                             don't like tea

                                                                       10

How  these were figured

Men =  total people  - women = 90 - 57      =    33

Men who like tea =  total men - those who don't lke tea  = 33  - 7 =  26

Women who like tea = total who like tea - men who like tea =  73 - 26  =  47

Women who don't like tea =  total woman - those who like tea  = 57  - 47  = 10 

b)    Probability  =       womwn  who lke tea  /  total who like tea  =     47 / 73 

Of the peope who like tea    47 are women   26 are men      47/(47+26) = 47/73

No picture shown, grannyg.....

Diameter is just   2 x radius   

circumference = pi  x  diameter   that you found in the first step above.....

a/b  x   b/c   =   3/4  x  8/9  = a/c = 24/36    =  a/(a+6)

                                                        24(a+6) = 36 a          24a + 144 = 36a      a = 12        a/b =3/4    12/b= 3/4     b= 16

                                                                                                                                            a/c =24/36    12/c = 24/36    c = 18

12 + 16 + 18 =46 cm

WHICH QUESTION THOUGH

D)revere

I just need feedback because I want to make sure it's perfect

Probably not, but he IS asking a lot of problems.... maybe he just needs help.
