Answer:
B.
Step-by-step explanation: The answer is b because 65.04 is the answer we get from finding the difference of those irregular triangles and the circle.
P.S. They must be done seperately.
 
        
             
        
        
        
Answer:
Step-by-step explanation:
1 gallon = 3.78litres
hence if the acid is $33.19/gal
3.78 litres will be sold for $33.19
while 
1 litre will be sold for $33.19/3.78
1 litre will be sold for $8.78
hence the cost per liter is $8.78
 
        
             
        
        
        
Answer:
the first one
the third one
the fourth one
Step-by-step explanation:
1. x <em>does</em> equal 9
2. the equation would lead to x being canceled out so there would be an x in your answer
3. x <em>does</em> equal 30
4. x <em>does</em> equal 6
5. x should equal 135
 
        
             
        
        
        
Since we want to find the value of <em>k</em><em> </em>where the limit exists, set both equations equal to each other. Then substitute <em>x</em> = -1 in for each equation to find <em>k</em><em>.</em>
<em> </em>
</em>
1. Set both equations equal.

2. Substitute <em>x</em><em> </em>= -1.

3. Solve for <em>k</em><em> </em>by adding <em>k</em><em> </em>to both sides. Continue the process of solving the equation.


Thus, <em>k</em><em> </em>= -2. Check by graphing the function.
