Answer:
20% of 1100 is 220, so two hundred and twenty students brought their lunch to school on Thursday (and every other school day).
Step-by-step explanation:
The day of the week is a distraction.  All you need to know is that 20% of 1100 students bring their lunch to school every day. 20% of 1100 is 200 + 20, or 220. So 220 students bring their lunch to school every day.
 
        
             
        
        
        
Answer: 14.967
Step-by-step explanation:
Use Pythagorean Theorem to find the missing length.  
a² + b² = c²        
x² + 10² = 18²      
x² + 100 = 324         [Subtract 100 from both side]  
           x²= 224        
       √x² = √224     [solve the square root from both sides]
         x   ≈  14.967
 
        
             
        
        
        
Answer:
<u>The equal monthly payment during 48 hours for buying a car is US$ 187.82</u>
Step-by-step explanation:
Loan from the bank to buy a car = US$ 9.015.20
Period of time to pay back the loan = 48 months
Form of payment = Equal monthly payments
Monthly payment = Loan from the bank / Period of time
Monthly payment = 9,015.20 / 48
<u>Monthly payment = US$ 187.82 (rounding to the nearest cent)</u>
<u>Each equal monthly payment during 48 months is US$ 187.82</u>
