Answer:
6.2
Step-by-step explanation:
We presume your "k-value" is the k in the exponential decay term ...
e^(-kt) . . . where t is the number of time units
This is 1/2 when ...
ln(1/2) = -kt
t = ln(1/2)/(-k) = ln(2)/k
t = 0.69315/0.1124 ≈ 6.2
The half life is about 6.2 time units.
3x12=36
36+7= 43
The answer is 43

Step-by-step explanation:
The level of a lake was 8 inches below normal.
Now, it is given that the water level decreases 
inches in June and

Therefore, the new level of water with respect to the normal level will be
= - 8 - 1.25 - 2.375
= - 9.625 inches
= inches. (Answer)
