Answer:
$42.5
Step-by-step explanation:
Answer:
15 divided by 1/5 is equal to 1.
A suitable calculator can row-reduce the augmented matrix.
first number: 3
second number: 1
third number: 8
It will be 0.0625 because you can use a calculator and do 14/224
One possible way:
-86+(4*12)=-38
-86 is the number where the diver is. 86 feet below the surface.
4*12 is the total number of feet he has ascended in 12 minutes.
Because he is ascending, so you add 4*12 (or 48) to -86.
The answer is -38, meaning he's 38 feet below the surface.
The diver is now 38 feet below the surface.
Hope this helps.
