Answer:
5/9 m^2
Step-by-step explanation:
the area of a rectangle is length * width
So the area = 5/6 m * 2/3 m = 10/18 m^2 = 5/9 m^2
Since the diver is being pulled up at a rate of 18 feet per minute, measuring his movement for the past 14 minutes, we will use −18 for the movement over those 14 minutes. So, his depth 14 minutes ago is given by the expression:
= 
= 
Hence, 14 minutes ago, the diver was 437 feet below the sea level.
This is simultaneous equation btw if you want to search up the lesson
3m-n=5
2m+5n=7
multiple the first equation by 5 so it could be equal to the second equation
15m-5n=25
2m+5n=7
the -5n and +5n cancel each other!
so it’s
15m=25
2m=7
(add the equations together)
17m=32
m=1.8
now take an equation from above (the original ones)
3m-n=5
3x1.8-n=5
5.4-n= 5
n= 0.4
ANSWER:
m= 1.8
n=0.4
Answer:
