The equation is:   and Julianne will begin making a profit after 168 days.
 and Julianne will begin making a profit after 168 days.
<em><u>Explanation</u></em>
Her total start-up cost is $52,000.
Each day, she spends $650 on operating costs (like utilities and wages) and she earns $960 per day from her students' lesson fees.
If the number of days to overcome the start-up cost is   , then
 , then 
the total operation cost spent in   days
 days  and
 and 
the total students' lesson fees earned in   days
 days 
<em><u>Part A:</u></em>   The equation to represent the situation will be:    
   
<u><em>Part B:</em></u><em> </em><em>  </em>Julianne will begin making a profit when....

So, Julianne will begin making a profit after 168 days.
 
        
             
        
        
        
Answer:
48°
Step-by-step explanation:
We can use the explanations from my previous answers to solve this. Lines are 180 degree angles. Use the equation: x + 132 = 180
Solve that:
180 - 132 = 48
 
        
                    
             
        
        
        
Answer:
86
Step-by-step explanation:
In this question, we are asked to calculate the average mean score for a group of students split into two different emerging groups. 
We calculate the total score for each of the groups. This is done by multiplying the average score by the number of students. 
Total score of section A is 15 * 80 = 1,200
For section B, total score is 20 * 90 = 1,800
Overall score is thus 1200 + 1800 = 3000
We add the scores together and divide by the total number of students in both sections
Average score is thus 3000/35 = 85.71 which is approximately 86
 
        
             
        
        
        
Answer:
I think it is acute because if the angle was over 90 degrees it would be and obtuse then
