Answer:4.2
Step-by-step explanation:
To solve the equation 54m = 51^2 we first calculate the square of 51. We can rewrite our equation as 54m = 2601. Now we divide by 54 on both sides to get m = 2601/54. 2601 is not divisible by 54, but we can simplify 2601/54 to 289/6 by dividing by 9 on both sides.
Explanation
The model has the form
Where a=initial amount
y= final amount
K= growth rate constant
t= time
When 140 kg of substance is left after 7 hours, the formula can be remodeled to be.
Therefore, the first solution is
For part b we have 16 hours.
Thus, the answer is 36kg
