Answer: 40 students.
Step-by-step explanation:
 To solve this problem you mmust apply the steps shown below:
 1. You know that there is a total of 100 students, then you can say that the 100% is 100 students.
 2. Then, to calculate how much would 40% be, you must multiply 100 students by 40% which you rewrite as a decimal by dividing it by 100, as following:
 40%/100=0.4
 Then 40% of the students would be
 100 studens*0.4=40 students
 
        
                    
             
        
        
        
Answer:
   c)  0.0156
Step-by-step explanation:
The general term a[n] of a geometric sequence is given in terms of the first term a[1] and common ratio r as ...
   a[n] = a[1]r^(n-1)
The given sequence has an initial term of a[1]=8 and a common ratio of 4/8=1/2. Then the general term is ...
   a[n] = 8(1/2)^(n-1)
The 10th term is then ...
   a[10] = 8(1/2)^(10-1) = 8(1/2)^9 = 8/512
   a[10] = 0.015625 ≈ 0.0156

Answer:
x = 10
Step-by-step explanation:
First, subtract 10 from both sides
Next, Simplify 
Then, subtract 5/3x from both sides
After, simplify
Lastly, multiply both sides by 3
Then finally simplify for your final answer of x = 10
Hope this helps! :)
