Answer:
C. 2,150
Step-by-step explanation:
We know that out of 120 passengers, 86 were satisfied with the service. 
To find the percentage amount of passengers who were satisfied, we can divide 86 by 120 and get 0.716 repeating (about 71.6%). 
Then, we can multiply the total number of passengers, 3,000, by that number and get 2,150.

Answer:
 - 
Step-by-step explanation:
Step 1: Add the numerator fractions.
2/5 + 3/10 
Here we have to find LCD, the LCD of 5 and 10 is 10
                                          (2*2) + 3         4 + 3
Therefore,  2/5 + 3/10 = ---------------  = ------------------
                                           10                     10
= 7/10
Step 2: Now substitute 2/5 + 3/10 = 7/10 in the given fraction, we get
  7/10
=  ----------
      -7/9
If we have fraction over fraction, we have to find the reciprocal of denominator fraction and multiply.
The reciprocal of -7/9 is -9/7
Step 3: Now multiply 13/10 and -9/7
= (7/10) x (-9/7)
= -9/10
=-9/10
The answer is  -
 
        
                    
             
        
        
        
Answer:
SA = 156π
Step-by-step explanation:
The formula for surface area of a cylinder is 
SA = 2πr² + 2πrh   where r is the base radius, and h is the height.
We are given r = 6 and h = 7.  Plug in those values and evaluate...
SA = 2π(6²) + 2π(6)(7)
SA = 2π(36) + 2π(42)
SA = 72π + 84π
SA = 156π
