Answer: The solutions are not viable because the amount of the sale cannot be negative.
Step-by-step explanation:
The solution A = -5 is not viable because A represents the amount of sale in dollars and so cannot be a negative number. The minimum amount that a person can make from sales is $0 so anything less than that is not viable.
For instance, if you are selling shoes for $4 each and make no sales in the day, your sales would be $0. It is not possible that your sales would be -$4.
Answer:
32
Step-by-step explanation:
the number of options for doors (2) times the number of options for cylinder (2 )times the number of colour options (8) (2x2x8) is 32. My apologies I don't know about number 5
The angle of elevation from point C to point A is 
<em><u>Solution:</u></em>
Given that we have to find the angle of elevation from point C to Point A
Given in figure that, angle A = 
Given is a right angled triangle ABC where angle B = 
We have to find angle C
The angle sum property of a triangle states that the angles of a triangle always add up to 180°
Therefore, in given triangle ABC
angle A + angle B + angle C = 180
Therefore angle C =
