Answer:
New position = -525 ft or 525 ft below the sea level
Step-by-step explanation:
Lets h be the height of the sea.
Given:
A submarine was situated 800 feet below sea level.
It is ascends 275 feet.
We know that h = 0 on the surface of the sea.
When we go below the surface vertically inside the sea the height will become negative.
So the submarine was situated h = -800 feet below the sea level, and it is ascends 275 feet from -800 feet.
So the new height of the submarine is.


Therefore the new position of the submarine is 525 below the sea level.
Answer:
D. 68+(6x+4)=180
x = 18
Step-by-step explanation:
"Supplementary angles" are angles that add up to 180°
So we add the twi angles 68+(6x+4) and that equals to 180°.
68 + 6x + 4 = 180
add 68 and 4
72 + 6x = 180
subtract 72.
6x = 108
divide by 6.
x = 18
I think the answer is B but I'm not sure
Answer: 40:8
Because if you cross multiply they’d all be even
Answer:
B) 4/5 ; likely
Step-by-step explanation:
If 2/10 (or 1/5) is the possibility of getting a red then it is likely the remaining will not be red.
So , it is likely 4/5 of the rest won't be red.
