I would measure it in meters because it is an easier measurement to use, and the average bench is around 1.5 meters.
the distance from (-2,2) to (5,-3) is 8.6,
(5,-3) to (-4,-1) is 9.2
(-4,-1) to (-2,2) is 3.6
8.6+9.2+3.6= 21.4
so the perimeter is 21.4
<em>E(Jeter) = 0.38 and E(Pujols) = 0.45, so back Pujols.</em>
10% = 10g/100ml. Ergo, 15ml/100ml (10g) = 1500mg of KCL
.9% NACL = 9g/1000mL, Ergo = 9000mg NaCl
Now we have to figure out how many mEqs of each salt we have.
MW of NaCl = 58.5
MW of KCl = 74.5
So, in moles, we have:
1500 KCl / 74.5 = 20.13 mmol KCl
9000 NaCl / 58.5 = 153.85mmol NaCl
Because the valence of both ions is one, as an example, it would be both 20.13 mEq of Cl- and K+ from 20.13 mmoles of KCL.
So, just add the two together, 20.13 + 153.85 = 174-ish.
(5-3x+2y-2x+y)-(3x-7y+9)= (5-5x+3y)-(3x-7y+9)= 5-5x+3y-3x+7y-9= -8x+10y-4= 2(-4x+5y-2)
