Answer:
13. (A, b, C) = (30.66°, 91.042, 25.34°)
14. insufficient information
Step-by-step explanation:
13. The Law of Cosines can help you find the side opposite the given angle. Then that can be used with the Law of Sines to find the other angles.
b = √(a² +c² -2ac·cos(B)) = √(56² +47² -2(56)(47)cos(124°)) ≈ √8288.59
b ≈ 91.042
__
A = arcsin(a/b·sin(B)) ≈ arcsin(56/91.042·sin(124°)) ≈ 30.66°
C = 180° -124° -30.66° = 25.34°
The missing dimensions are (A, b, C) = (30.66°, 91.042, 25.34°).

14. One side and one angle do not define a unique triangle. There is insufficient information to find f.
First you need to understand the structure of the commission.
The first part is 6% commission on sales up to $500.
The second part is 8% commission on sales over $500.
Note that the second part doesn't mean that a sale of $800 gets 8% of $800.
It means that once we have reached $500, any *further* sales get 8%.
Since $800 is $300 more than $500, the commission is
6% of $500 +
8% of $300
The first thing she did was work out the excess above $500.
Then she worked out the two percentages in two separate parts.
The second part seems to have incurred a cut and past accident, not sure if that is yours or it was already done.
A scatter plot is made with the data shown:
<span><span>Number of Weeks in Business123456789</span><span>Number of Customers0246810121416</span></span>
What type of association will the scatter plot for this data represent between the number of weeks in business and the number of customers?
Okay. So when you solve 864/31 on a sheet of paper and you divide it properly, the remainder you get should be 27. The answer is B: 27.
