Answer:
72/149
Step-by-step explanation:
Just to clarify, the curly braces mean the same thing as normal parenthesis.
(12 + 5^2) = (12 + 25) = 37
(-7-15)^2 = (-22)^2 = 484
6^3 = 216
(12 + 5^2) - (-7-15)^2 = 37 - 484 = 447
6^3 / ((12 + 5^2) - (-7 - 15)^2) = 216 / 447 = 72/149

Answer:
150 pennies were lost altogether
Step-by-step explanation:
Let the initial number of pennies owned by Dante be x pennies
Let the initial number of pennies owned by Mia be y pennies
Mathematically ;
x + y = 350 •••••••(i)
So after losing half, dante will have x/2 pennies left.
Mia lost 1/3 so she will have 2/3y left
So after all the losses, they both had equal amount of pennies
This means that;
x/2 = 2y/3
Cross multiply;
3x = 4y •••••••(ii)
Let’s solve both equations simultaneously;
From i , x = 350-y
Substitute this into equation ii
3(350-y) = 4y
1050-3y = 4y
7y = 1050
y = 1050/7
y = 150
since x = 350-y
x = 350-150 = 200
Now Dante loss x/2 = 200/2 = 100
Mia lost 1/3y = 1/3 * 150 = 50
Total pennies lost = 100 + 50 = 150
Answer:
36 minutes
Step-by-step explanation:
Depth of the fjord = 1308 m
Rate at which the submersible dives = 35 meters/minute
Distance to the bottom of the fjord should be 48 m
Distance the submersible has to go underwater is 
Time is found by dividing the distance the submersible has to go underwater by rate at which the submersible dives
The time taken by the submersible to dive the required distance is 36 minutes.
