Answer:
3,672
Step-by-step explanation:
Given the sequence 6, 9, 12...
The sequence is an arithmetic sequence
first term a = 6
common difference d = 9 - 6 = 12 - 9 = 3
number of terms n = 48
Sn = n/2[2a+(n-1)d]
Substitute the given values
S48 = 48/2[2(6)+(48-1)(3)]
S48 = 24(12+(3*47))
S48 = 24(12+141)
S48 = 24(153)
S48 = 3,672
Hence the sum of the first 48terms is 3,672
The first answer is the correct one
Answer:
The answer will be listed below.
Step-by-step explanation:
To graph the equation, first mark down your y-intercept which would be 5. Look at the y-axis and put a dot on 5. Now you must graph the slope of the line. To graph the slope, you would use rise/run (1/3). You would start on 5 and go up one and to the right three times. Keep repeating the process until you run out. Now draw the line through the dots and you did it!
Answer:
I. $291.67 per passenger
II. $583.33 per passenger
Step-by-step explanation:
The cost of flying the passenger plane from A to B is $70,000.
If the Capacity of the plane is 240 people.
(I)At 7A.M and 4P.M., the average cost per passenger is given as:
Average Cost=Total Cost/Number of Passengers
=70000/240=$291.67 per passenger
(II)At 10AM and 1PM, the flight is only half full, it has 120 passengers.
Average Cost = 70000/120=$583.33 per passenger
