Answer:
2.75
Step-by-step explanation:
 
46 divided by 4 is 11r2 then convert the 2 into a decimal which is 11.02 then divide it by 4 which is 2.75 i didn't double check so its its wrong im sorry
 
        
             
        
        
        
Answer:
the answer is 1.453
Step-by-step explanation:
i am not sure about the answer but here are my steps. first he says in the 1990s  there was a deforestation rate of about 0.48%per year. and 1 is the rate of land that is shrinking. this means that if Brazil had a forest of area x then
x(0.48%)=1 therefore x=2.083
lets use that in this equation
the area left (the final answer) 2.083(0.48)^35= 1.453
(i asked about the unit its measured with because if it is measured by thousands of squared meters or kilometers just big unit measured to be exact my answer would be correct)
 
        
             
        
        
        
Given : 2D + 1L = 100, 
And D + L = 70
This is a simultaneous equation can be solved as follows 
 2D + L = 100
 - D - L = -70
————————————-
 D - 0 = 30
i.e D (number of dudes) = 30
Therefore, since we already know the fraternity sold 70 tickets in total, 
70 -30 = 40 (the number of ladies attended)
