Answer:
80 ÷ 4 = 20, so 100 ÷ 4 = 25 students
Step-by-step explanation:
Is means equals to  and of means multiply
20 = 80% * N
20 = .80 N
Divide each side by .8
20 / .8 = N
25 = N
there are 25 students
 
        
                    
             
        
        
        
We know that
the length of Q is 25% more than the length of p
so
length Q=1.25*40--------> 50 cm
the area of Q is 10% less than the area of p
Area Q=50*y
Area P=40*x
so
50*y=0.90*[40*x]---------> 50*y=36*x-------> x/y=50/36---> 25/18
the answer 
the ratio x:y is 25:18
        
             
        
        
        
For this case we have the following function:
 f (x) = x ^ 5
 We apply the following transformations:
 reflect over the y axis:
 f (x) = (- x) ^ 5
 shift 1 unit left:
 f (x) = (- x + 1) ^ 5
 vertically compress by 1/3:
 f (x) = (1/3) (- x + 1) ^ 5
 Answer:
 A function that results after applying the sequence of transformations is:
 f (x) = (1/3) (- x + 1) ^ 5

Answer:
Let's call:
f = price of 1 cup of dried fruit
a = price of 1 cup of almonds
In order to build the linear system, you need to consider that the total price of a bag is given by the sum of the price of cups times the number of cups in each bag, therefore:
Solve for a in first equation:
a = (6 - 3f) / 4
Then substitute in the second equation:
41/2 f + 6 · (6 - 3f) / 4 = 9
41/2 f + 9 - 9/2 f = 9
16 f = 0
f = 0
Now, substitute this value in the formula found for a:
a = (6 - 3·0) / 4
   = 3/2 = 1.5
Hence, the cups of dried fruit are free and 1 cup of almond costs 1.5$
