13.4+1.96(6.8√352 )=      note :  √352    =    352^(1/2)    .....so we have

13.4 + 1.96 [ 6.8 * (352)^(1/2)  ]     =    about   263.455

102/ 576   ≈    0.17708  ≈   17.71%

2 = y - (-3/5)    simplify

2 = y + 3/5      subtract 3/5 from both sides

2 - 3/5  = y        note : 2 = 10/5

10/5  - 3/5  = y

7/5  = y

(3/5)lb  / 1 bowl    =  10lbs / ?bowls        cross-multiply

?bowls* (3/5)  = 1 *10

?bowls * (3/5)  = 10      multiply both sides by 5/3

?bowls = 10 (5/3)   = 50/3 bowls = [16 + 2/3] bowls

Here's yet another solution:

Alex  walks at 3 mph...which equals 3 *5280/60  = 264 ft. per minute.. ....so .....in 7 minutes....he is........7*264  =  1848 feet ahead of Ben

And Ben walks at 3.5 mph  = 3.5 * 5280 / 60  = 308 ft per minute

So....the distance that Ben closes on Alex every minute = 308 - 264 = 44 ft

So....to close the 1848 ft....it will take Ben 1848/44  = 42 minutes after he starts.......and he will be

3.5 (42/60)  = 2.45 miles from home

I think you might mean this :

49x^2-42x+9       .....if so,  this is a perfect square trinomial

(7x - 3) (7x - 3)   =

(7x - 3) ^2

[5/6]h-[7/12] = [-3/4]h-13/6         let's multiply through by the common denominator of all these fractions, i.e.,  12   .....   so we have

10h - 7  = -9h - 26       add 9h, 7 to both sides.....

19h = -19           divide both sides by 19

h  = -1

The number that do not  = 1782 - 567  =   1215

So.......the percentage that do not   =   1215 / 1783  ≈  0.681  ≈  68%

Note.......2^100  ends in 76

And  [ ....... 76]^n   where n  is a positive integer always ends in 76 

So

2^2000  =   [2^100]^20  = [ ........76]^20  will also end in 76

And 2^8  ends  in 56

So........2^2008   = 2^2000 *2^8 =    [  ...........76] * [ 256]    =  ends in 56

A_trapezoid =   (1/2)h [ b₁ + b₂  ]

So.....the area  =

100 = (1/2)h [ b₁ + b₂  ]  =  (1/2)(5) [ b₁ + b₂]

Multiply both sides by 2  and divide by 5

40  = b₁ + b₂

So.......we are looking for base lengths that sum to 40  using whole numbers.....

A possible combination is  :  b₁ = 30 and b₂  = 10
