I = V/R
Initially .300 = 50/R R = 166.667 ohms Cutting the wire in half also cuts R in half to 83,33 ohms
I = 300/83.33 = 3.6 amps = 3600 mAmps
med in ingredients = med in final solution
x = 20 % cc amount of med = .20 x
(10-x) = 5% cc amount of med = .05 (10-x) summed they equal .095 (10)
.20x + .05(10-x) = .095 (10) solve for 'x' = the cc of 20%
then 5 % cc = 10 - x
Thanx , Heureka ! See answer below....turns out I entered it incorrectly in WA after all.... (transcribed as 'z' instead of '2z' .... D'Oh!)
From the 9th term to the 25th term is 16 common differences

-6 + 16 ( 5/4) = 14
WolframAlpha says it is 84 ....but I do not know how to derive it ....Anyone?
Area of triangular pyramid is 1/3 * base area * height
can you find the area of an equilateral triangle with sides = 14 ?
y = k/x^2
yx^2 = k
15 (24)^2 = 8640
13 (x^2) = 8640
x^2 = 8640 / 13
x = 25.78 (taking the positive root)
3(x - 4) + 2(x^2 - x + 7) - 5(x - 1) + 8(x^2 - x + 3) - 4(x - 5)
3 (-4) + 2(7) -5(-1) ...... can you finish ?
Daniel is traveling 5 m/hr faster and will take 1/3 m / 5 m/hr to close the 1/3 mile gap = 1/15 hr = 4 minutes
