Answer:
A.  =
 = 
Step-by-step explanation:
  of the students wore shorts.
 of the students wore shorts.
  of the students wore jeans.
 of the students wore jeans.
Converting the fractions of the students who wore shorts and jeans respectively;
 = 0.25
 = 0.25
  = 0.25
 = 0.25
This means that the ratio of students who wore shorts is the same as that of students who wore jeans.
i.e  =
 = 
 
        
                    
             
        
        
        
Answer:
f(9) = -37
Step-by-step explanation:
f(n) = -5n + 8
f(9) = -5(9) + 8 
f(9) = -45 + 8
f(9) = -37

plz mark me as brainliest ...TOOK ME LONG TIME TO TYPE
 answer = CI = 3108 RUPEES
<u>Step-by-step explanation:</u>
i am doing the method in which u find the simple interest of first year then second year.
SI FOR 1ST YEAR= P X R X T / 100
SI = 2700 X 20 X 2 / 3 X 100   ( RATE OF INTEREST IS 20 / 3)
SI = 108000/300
SI = 360
SI FOR SECOND YEAR = 
P = 2700 + 360= 3060
SI = 3060 X 20 X 2 / 300
SI= 122400 / 300
SI = 408
COMPOUND INTEREST (CI) = PRINCIPLE + SI OF 2ND YEAR
CI = 2700 + 408 
CI = 3108 RUPEES
or u can solve be the method
CI = amount - principle
Amount= principle x (change in ratio) raised to time
