Answer:
380 feet below sea level.
Step-by-step explanation:
Given:
A submarine is is 250 feet below sea level.
It descended another 130 feet.
Question asked:
How many feet below sea level is the submarine now?
Solution:
A submarine is initially below the sea level = 250 feet
Another descend below the sea level = 130 feet
Now, we have to calculate the final level of submarine below the sea level and for it we will simply add initial level to the another descended depth:-
250 feet + 130 feet = 380 feet.
Therefore, submarine is now 380 feet below sea level.
6x 24 /5 = 68 feet is the sender
Answer:
78 inches or 174 inches (see explanation)
Step-by-step explanation:
If the perimeter is 64 feet, that means that each side is 8 feet, since there are 8 sides (64/8=8). 8 feet is 96 inches (8*12=96). 96-18=78, so the minimum length of wood he needs for the ledges is 78 inches, assuming you're not counting the wood for the perimeter, too (in which case it would be 174 inches) (78+96=174).
