because you dont e=realize that you have to put question mark at the end of the sentence

Hi Quazars,

Yes I took a look but I have drawn a blank as well. 

The Wolfram Alpha solution is really messy.  I do not think that there is any neat solution.

as n becomes very large (we say it tends to infinity)  then1/n becomes very small (we say it tends to zero)

So as n tends to infinity, 1  + 1/n    tends to    1 +0   which  = 1.

So (1 + 1/n)^2   tends to  (1+0)^2  =1^2  =1

plz tell me how to calculate the x

Hmm.  You should check your second calculation asinus!

4+7*3^2-(2+5)*6 → 4 + 63 - 7*6 →  67 - 42 → 25

.

The small intestine is (n) and longer than the large intestine, if the large intestine is 5 feet, then n > 5 and  (n - 5 > 0). 

We genetically enhanced chimps keep our gut instincts sharp to solve both large and small intestinal problems. 

hiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiii

Thanks Alan,

I like your answer it is nice and straight forward :)

what is 4/5 x 3/8

\({\color{blue}\frac{4}{5}\times\frac{3}{8}=\frac{12}{40}=\frac{3}{10}}\)    !

Note that in the above Guest#1 should have speed of light in meters per second.

Also note that n herz = n per second

.

Can also think of it this way:

12 people shake hands with 10 others, but A shaking hands with B is the same as B shaking hands with A, so total number of handshakes is 12*10/2 = 60.

In a hot air balloon race a ballon traveled 1800 km from Germany to Greece in 60 hours. What was its average speed in km per hour?

The average speed in km per hour is

\({\color{blue}v = \frac{s}{t}= \frac{1800km}{60h}= 30\frac{km}{h}}\)     !

man 1     10 shakes    then he is out

man 2      9 shakes then out

man 3      8 shakes then out

man4       7 shakes then out

man5       6 shakes then out

last man   5 shakes then out

woman1   5 shakes

..

woman 5  1 shake

total

10+9+8+7+6+5   +5+4+3+2+1 = 60 handshakes 

What (6 1/4 feet tall and 3 feet wide) is the area of the door?

\(A =6 \frac{1}{4}feet\times 3feet=\frac{25}{4}feet\times 3feet \)

\(= \frac{75}{4}feet^2=18\frac{3}{4}feet^2\)

The area of the door is \({\color{blue}A=18\frac{3}{4}feet^2}\) .    !

How many 4-digit numbers have no repeating digits?

If no zeros

9C4*4!

nCr(9,4)*4! = 3024

If there is a zero (zero cannot be the first digit)

9C3*3*3!

nCr(9,3)*3*3! = 1512

3014+1512 = 4526

Thanks Ginger :)

idk

Solve for a:
112 a^2-168 a+63 = 0

Divide both sides by 112:
a^2-(3 a)/2+9/16 = 0

Write the left hand side as a square:
(a-3/4)^2 = 0

Take the square root of both sides:
a-3/4 = 0

Add 3/4 to both sides:
Answer: |a = 3/4

Hello and goodbye

Tan(30) =Height of tree/40

0.577350 =H / 40

H = 40 x 0.577350

H=23.1 feet - the height of the tree.

Wavelength(meters) =speed of light(meters) / frequency(herz)

Simplify the following:
(6+1/2) y+(2+5/6) y+1/4+3/4+2+4

Put 6+1/2 over the common denominator 2. 6+1/2 = (2×6)/2+1/2:
(2×6)/2+1/2 y+(2+5/6) y+1/4+3/4+2+4

2×6 = 12:
(1/212+1/2) y+(2+5/6) y+1/4+3/4+2+4

12/2+1/2 = (12+1)/2:
(12+1)/2 y+(2+5/6) y+1/4+3/4+2+4

12+1 = 13:
(13 y)/2+(2+5/6) y+1/4+3/4+2+4

Put 2+5/6 over the common denominator 6. 2+5/6 = (6×2)/6+5/6:
(13 y)/2+(6×2)/6+5/6 y+1/4+3/4+2+4

6×2 = 12:
(13 y)/2+(1/612+5/6) y+1/4+3/4+2+4

12/6+5/6 = (12+5)/6:
(13 y)/2+(12+5)/6 y+1/4+3/4+2+4

12+5 = 17:
(13 y)/2+(17 y)/6+1/4+3/4+2+4

Put each term in (13 y)/2+(17 y)/6+1/4+3/4+2+4 over the common denominator 12: (13 y)/2+(17 y)/6+1/4+3/4+2+4 = (78 y)/12+(34 y)/12+3/12+9/12+24/12+48/12:
(78 y)/12+(34 y)/12+3/12+9/12+24/12+48/12

(78 y)/12+(34 y)/12+3/12+9/12+24/12+48/12 = (78 y+34 y+3+9+24+48)/12:
(78 y+34 y+3+9+24+48)/12

Grouping like terms, 78 y+34 y+3+9+24+48 = (78 y+34 y)+(48+3+24+9):
((78 y+34 y)+(48+3+24+9))/12

78 y+34 y = 112 y:
(112 y+(48+3+24+9))/12

48+3+24+9 = 84:
(112 y+84)/12

Factor 28 out of 112 y+84:
28 (4 y+3)/12

The gcd of 28 and 12 is 4, so (28 (4 y+3))/12 = ((4×7) (4 y+3))/(4×3) = 4/4×(7 (4 y+3))/3 = (7 (4 y+3))/3:
Answer: |7/3 (4y + 3)
