S will equal -7 if thaats the question youre asking
Answer:
$0.5
Step-by-step explanation:
Given :
Hours ___Lot A Cost ($) ___ Lot B Cost ($) 4____________19.00 _____ 20.00
8 ___________ 33.00 ______ 32.00
Using the equation :
y = mx + C
m = slope = Hourly charge
C = intercept = set park fee
m = y2 - y1 / x2 - x1
For LotA:
m1 = (33 - 19) / (8 - 4)
m1 = 14 / 4
m1 = 3.5
For LotB:
m2 = (32 - 20) / (8 - 4)
m2 = 12 / 4
m2 = 3
Since, m is the hourly cost :
Difference = m1 - m2
= 3.5 - 3
= $0. 5
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.
The value of A has been illustrated, computed and proven based in the triangle given.
<h3>How to calculate the triangle?</h3>
It should be noted that that a triangle is a shape that has three sides and the value of the addition of all the angles are equal to 180°.
Based on the information that's given, it should be noted that the value of angle A, angle B, and angle C will be equal to 180°.
In this case, the following can be deduced:
A = 5x
B = 90°
C = x + 10°
Therefore, A + B + C = 180° (sum of angles in a triangle)
5x + 90 + x + 10 = 180°
6x = 180° - 90° - 10°
6x = 80°
x = 80/6
x = 13 1/3
Therefore, the value of A will be:
= 5x
= 5 × 13 1/3
= 66 2/3
Therefore, A is 66 2/3.
