Samples of three different compounds were analyzed and the masses of each element were determined. Compound Mass Mass N(g) O(g) A 5.6 3.2 B 3.5 8.0 C 1.4 4.0 If you were John Dalton and had never heard of a mole, which of the following would you think were possible sets of for...

Use the Molarity Formula Molarity= moles/liters of solution Molarity= moles/0.050 Liters To find moles you have to find the moles of each sample of KBr. SO 1.00M KBR times .025liters =.025moles And then 0.800M KBR times .075liters=.060moles. Then you add the moles of both samp...

third one is true

As time passes, the ticket sales get higher. Each time you plug in different values of X, the day tickets go on sale, your Y value increases.
Algebra
For D)..... Your parabola should be negative because of the -2X^2. SO the parabola when you graph it is a backwards U. The middle of the backwards "U" has a high maximum so your tickets should be at a peak during the middle of the sale.

I believe you get .0030864. solve what's in the parenthesis first then ^2. turn fractions into decimal format then add them and ^2.
