Answer:
21 shells
Step-by-step explanation:
10+23+21=64
64/3=21.33
always round down, you'll have one left over
 
        
                    
             
        
        
        
Answer:
There are two options: b)  , c)
, c)  .
.
Step-by-step explanation:
By Trigonometry, we know that function tangent is equal to the following identity in terms of functions sine and cosine:
 (1)
 (1)
If we know that  and
 and  , then
, then  . Hence, we have two possibilities: b)

<h2>Answer</h2>
C.) 1
<h2>Explanation </h2>
Remember the rules for shifting functions: 
 shifts the function b units upward
 shifts the function b units upward
 shifts the function b units downward
 shifts the function b units downward
 shifts the function b units to the left
 shifts the function b units to the left
 shifts the function b units to the right
 shifts the function b units to the right
Since we want tho shift  5 units to the right, we are using the rule:
 5 units to the right, we are using the rule:  shifts the function b units to the right; in other words, we need to subtract 5 units to the input of the function:
 shifts the function b units to the right; in other words, we need to subtract 5 units to the input of the function: 


But notice that there is already a negative sign in  , so to get
, so to get  , k must be equal to positive 1.
, k must be equal to positive 1.
 
        
        
        
the answer will be 20 times 3 that is 60
