Answer:
88.5
Step-by-step explanation:
75 x .18
tip= 13.5
75 + 13.5 = 88.5
Lets say x = 89.99 and y = 56.49
P% * x = y
P% = y/x
56.49/89.99 = 0.6277
0.6277 * 100 = 62.77
But because we are looking for how much off the sale is:
100% - 62.77%
= 37.23%
The sale price is 37.23% off.
Answer: 3 mol of O₂
Solution:
The Balance chemical equation is as follow,
2 KClO₃ → 2 KCl + 3 O₂
According to this equation on decomposition 2 moles of Potassium chlorate (KClO₃) produces 2 moles of Poatassium chloride (KCl) and 3 moles of oxygen gas (O₂).
Therefore, when,
2 moles of KClO₃ produces = 3 moles of O₂
So,
2 moles of KClO₃ will produce = X moles of O₂
Solving for X,
X = (2 mol × 3 mol) ÷ 2 mol
X = 3 mol of O₂
Using above method you can calculate any amount of O₂ or KCl produced by decomposing any amount of KClO₃.
You can usually translate below to mean the number is minus or at least smaller than something else. In this case it is minus. So the answer is found as
535 - - 8 = 543 feet. The first minus sign means difference and the second means below sea level. (535 is feet above sea level). This is one of those cases where it makes sense to say that a minus times a minus is a plus.
Let's try this a slightly different way. Suppose there is a hill above a gully. The hill is 30 feet above the gully. The gully has a bottom that is 8 feet below where the hill begins. If you wanted to walk from the top of the hill to the bottom of the gully, how far would you have to go? Never mind all the plus and minus stuff. Just draw the picture, and see what happens. Or imagine you are doing the walking.
Wouldn't you have to go 30 + 8 feet? Isnt' that 38 feet? Same with your Louisiana problem. It (the Louisiana problem) is just more mathematical. And getting two minus signs to equal a plus is no easy trick.
Be sure you understand the answer to this problem. It is one of the cornerstone's of Algebra.
