About as many as Eric can shove in Max's tight little a*s

25000=11000(1+r)^4   divide both sides by 11000

(25/11)  = (1 + r)^4   take the positive 4th root of each side

(25/11)^(1/4)  = 1 + r   subtract 1 from both sides

(25/11)^(1/4)  - 1 = r  = 0.2278 = about 22.78%

If 4 is the number of years, then r=22.78% compounded annually.

If 4 is the number of quarters in 1 year, then r=59.28% compounded quarterly

Yep....it is irrational.....so......the digits never terminate.......

If the interest rate of 7% is compounded annualy then it will take=16.72 years

Assuming compound interest, we have

3.1P = P (1 + .07)^(t)    where t is the time......divide through by P......and we have

3.1  = (1.07)^(t)    take the log of both sides

log(3.1) = log(1.07)^(t)   and we can write

log(3.1) = t * log (1.07)    divide both sides by log(1.07)

t  = log (3.1) /  log(1.07)   = about 16.72 years

I'm assuming that beta is the angle oposite "e".....[thus, "e" is a leg]

The other non-right angle = 90 - 72 = 18 degrees

And we can find the length of the other leg , x , using the Law of Sines....so we have

x / sin 18 = 18.3 / sin 72   →   x = (18.3)(sin 18) / sin(72)  = about 5.95

The hypotenuse = sqrt(18.3^2 + 5.95^2)  = about 19.24

A- In both cases the negatives cancel each other and the result is left blank, which means +.

B- Only when ONE of them is negative.

A  Multiplying two negatives results in a positive

B  Multiplying a negative by a positive results in a negative.....also.......division of a positive and a negative results in a negative

1% = 1/100   ....so...

1,600,000,000 x (1/100) = 16,000,000

1%=1/100=.01 X 1.6^9=16,000,000=1.6 X 10^7

NO!!!!!!!!!!. Density=Mass/Volume.

I believe that "Guest's" formula is slightly incorrect.......

Density = Mass / Volume

D = Mass x Volume

heureka: Isn't 4 raised to ANY power ending in "0", always going to end in "76"?, i.e, 4^10, 4^70, 4^160, 4^500, 4^1000 and 4^2000......etc. But why?

1 2/3 + 2 1/30   =

1 + 2 + 2/3 + 1/30 =

3 + 2/3 + 1/30  =

3 + 20/30 + 1/30   =

3 + 21/30  =

3 + 7/10

(5/9)(-3/8)   = (5/8)(-3/9)  = (5/8)(-1/3)  = -5/24

If you have an ordinary pack of playing cards, remove the K, Q and J of spades, shuffle them and cut.

Clubs A to K represent 1 to 13, Diamonds A to K, 14 to 26 (add 13), Hearts A to K, 27 to 39 (add 26) and Spades A to 10, 40 to 49 (add 39).

Alternatively, if you could lay your hands on a 49 sided die ?
