Answer:
Solution : 8i
Step-by-step explanation:
We can use the trivial identities cos(π / 2) = 0, and sin(π / 2) = 1 to solve this problem. Let's substitute,
![8\left[cos\left(\frac{\pi }{2}\right)+isin\left(\frac{\pi \:}{2}\right)\right]](https://tex.z-dn.net/?f=8%5Cleft%5Bcos%5Cleft%28%5Cfrac%7B%5Cpi%20%7D%7B2%7D%5Cright%29%2Bisin%5Cleft%28%5Cfrac%7B%5Cpi%20%5C%3A%7D%7B2%7D%5Cright%29%5Cright%5D) =
 = 
And of course 1i = i, so we have the expression 8(0 + i ). Distributing the " 8, " 8( 0 ) = 0, and 8(i) = 8i, making the fourth answer the correct solution.
 
        
             
        
        
        
Answer:
106 : 84
Step-by-step explanation:
53 : 42 = 106 : 84
The ratio is already in lowest terms so found I an equivalent ratio by multiplying both terms by 2.
 
        
                    
             
        
        
        
To solve this problem you must apply the proccedure below:
 1. You have that one canned juice drink is 20% orange juice and another is 5% orange juice.
 2. You must make a system of equation, as below:
 x+y=15  (i)
 0.20x+0.05y=0.15x15   (ii)
 3. Now, you must find the value of x (the liters of the first canned needed) and y (the liters of the other canned needed):
 x+y=15  (i)
 x=15-y
 0.20x+0.05y=0.15x15   (ii)
 0.20(15-y)+0.05y=2.25
 y=5 liters
 x+y=15  (i)
 x=15-5
 x=10 liters
 4. Therefore, the asnwer is:
 10 liters of the canned juice drink that is 20% orange juice and 5 liters of the other canned juice drink that is 5% orange juice.
