The same question got answered here as well:

3 sec  = 1/20  of a  minute

So....

2.4  * 20  =  48  revs  /   min

And

48 * 2pi   =     96 pi  rads /  min  ≈  301.6  rads / min

Good job, Jenny   !!!!

Excellent work!!! I tried to use trigonometry, but it didn't work. 

i'm his sister! my name is actually charis but my user is matthew macdell based on a tv show character. thank you :))

[8 + 4 - 1] C [4 -1] =11C3 = 165 ways of distributing 8 watermelon candy

[7 + 4 - 1] C [4 - 1] =10C3 =120 ways of distributing 7 strawberry candy

Total number of ways= 165 x 120 =19,800 ways.

nay thee

thank you!

thank you for your help!

Awesome! thank you (:

fie! cometh h're and englut mine own coxcomb thee distemperate fooleth >:((

wherefore doth thee at each moment doth this to me

Excellent, AELN  !!!!

We do not  have  many people on here that  "do"  Geometry....so....you're a welcome addition  !!!

thee shouldst not calleth upon any oth'r nameth except charis

but i has't nay choice but to leaveth this questioneth because t looks liketh electric pavlov hast already answ'r'd t

2L  +  10  =  A        (1)

L +  A  =    118      (2)

Sub ( 1)  into (2)

L  +  ( 2L + 10)  =  118

3L  + 10  =  118    subtract 10  from each side

3L   =  108          divide  both sides  by  3

L =  36  =  Levi's weight

A  = 2 (36)  + 10   =    82  = Aaron's weight

a = 10 + 2l

l                                   summed they = 118

l     +  10+2l     = 118

3l    + 10 === 118

3l = 108

l = levi's wt = 36 #           a = 10 + 2l ==82 #

From the previous post  AB =  19/ 2 = 9.5

b^2 - 4ac    would be   (-2)^2 - 4 (5)(8) =   4 - 160 =  -  156   

uhhm, the problem says that aarons weight is 10 pounds greater than twice levi's weight. Soo, could you redo that answer plz?

By Vieta :

Sum of  roots  of  first  quadratic  =  -8/1  =  -8

Product of the roots  of  1st  quadratic = 4/1   =4

This implies, that, in the  second quadratic

-8 = -B/ A   ⇒   8  = B /A   ⇒  8A  = B        (1)

And

1 / A  =   4     ⇒  A  = 1/4         (2)

Sub  (2)  into (1)   and  we have  that

8 (1/4)  = B   =   2

So

A + B   =    (1/4)  +  2  =    9 / 4

I recommend using the Quadratic Equation. I'm too lazy I'm gonna go play some video games bye see you guys in a few hours!
