Answer:
<h2>70 ft</h2>
Step-by-step explanation:
120 below we can use a model to figure this out.
sea level is 0
the submarine <u>goes 120 down</u>, so its -120
it <u>goes up by 50</u>, so now its <em>70</em>
no other obstacles, 70 or A is your answer.
Answer:
p<4
Step-by-step explanation:
4p+2< 2(p+5)
Distribute: 4p+2<2p+10
Subtract 2 from both sides: 4p<2p+8
Subtract 2p from both sides: 2p<8
Divide and we get: p<4
100 would be correct because the 9 in the hundredths place rounds to a ten, and so does every other number.
Using equation of motion.
S = ut + (1/2)gt²
Where S = Height, t = time, g = acceleration due to gravity = 9.8 m/s²
time, t = 8 seconds
Since it was dropped from height, initial velocity, u = 0
S = 0*t + (1/2)gt²
S = (1/2)gt²
S = (1/2)*9.8*8² = 4.9 * 8 * 8 = 313.6
Therefore the ledge is 313.6 m tall.
$89.10 is the best guess.
