Answer:
Let's name each of the three sections of the rocket as:
-
payload and navigation
-
fuel
-
engine
Now, we are told that:
The top section is one-sixth the length of the bottom section:
(1)
The middle section is one-half the length of the bottom section:
(2)
The total length is 240ft:
(3)
We may begin by substiting (1) and (2) in equation (3), in order to find the value of the engine section
:
(4)>>>> Value of the engine section length
Then, we substitute this value of
in equations (1) and (2):
(5)>>>> Value of the payload and navigation section length
(6)>>>> Value of the fuel section length

Assuming early termination, Alice's fixed costs are $200 for the phone and $175 for the fee, for a total of $375. Her variable cost is $50 per month. Her total cost is ...
b. y = 50x + 375
30% of 18 tons is 5 2/5 tons.
18 - 5 2/5 = 12 3/5
The answer is 12 3/5 tons.
Hope that helped =)
