**Geometry**

if the pen has dimensions x by y, with x along the barn, then x+2y = 115 the area a is thus a = xy = (115-2y)y this is a parabola, with maximum at y=115/4 so, x = 115/2 so, a pen 115/4 by 115/2 gives the maximum area

Since the density is 1.00 g/mL, that means we can use 1.0 mL = 1.0 g, I remember that 1 mg/L = 1 ppm So 0.115 g/4.55 L = 0.02527 g/L or that x 1000 = 25.27 mg/L or 25.3 ppm. Your way: 0.115 g/4550 g + (.115 x 10^-6) = 0.115 g/4550 g + (negligible) =. 2.527 x 10^-5 g/1.0 g. ...

what is the question?

**statistics**

Use z-scores: z = (x - mean)/(sd/√n) x = 115 mean = 100 sd = 15 n = 3 Once you have z, use a z-table to determine probability. If the probability is low, then it would be unusual for the mean of a sample of 3 to be 115 or more. I hope this will help.

**Algebra**

income = 115 n cost = 8600 + 55 n so profit = 115 n - 8600 - 55 n = 60 n - 8600 That means we do not start making money until we sell 8600/60 = 143 1/3 of the players. After that we will make 60 dollars per unit.

**PHYSICS!**

In this case, not all of the ice melts. Let m be the number of grams of ice that melts. 115*81*1.0 = m*80 (80 cal/g is the heat of fusion) m = 116 g Note that is less than the amount of ice you started out with. So there is some ice left. Add that to the 115 g of liquid water ...

**math**

x + x + 13 =460/4 2x + 13 = 115 2x + 13 -13 = 115. -13 2x = 102 2x/2 = 102/2 x = 51 x + 13 = 64
