What your going to want to do is take graph paper each square is five feet draw whatever shape your room is on it and take perimeter and area I cant write the reflection as I don't know what room you have drawn. 
        
             
        
        
        
Step-by-step explanation:
The equation 0.5s+ 9.99=30 describes the situation. 
9.99 is the fixed amount 
0.5 is the cost for each song download
30 is the maximum amount spend for a month
Here 's' represents the number of songs download
0.5s+ 9.99=30 means 
0.5 times the number of songs plus the fixed cost 9.99 should be equal to 30 dollars.
The solution to this equation is s=40.02. 
s= 40.02  means 40 songs can be downloaded as per the budget 
 
        
             
        
        
        
Answer:
38°
Step-by-step explanation:
Complementary means that they add up to 90
So then to find the measure of angle 2, subtract the measure of angle 1 from 90. 
90-52=<u>38</u>
 
        
                    
             
        
        
        
30 × 5 = 150
150 - 110 = 40
40 ÷ 2 = 20
So 20 kids brought their own lunch
Hope this helped. Have a great day!
