Answer:
4.8 hours
Step-by-step explanation:
The formula for half life is given as:
t½ = t × In(2)/In(No/Nt)
Where
t½ = Half life
t = time in hours = 4
No = Initial amount = 10mg
Nt = Final amount after 3 hours = 6.5 mg
t½ = 3 × In(2) /In(10/6.5)
t½ = 4.8271216522281 hours
Approximately = 4.8 hours
The simplified solution to this equation is 5x - 115.

there's kinda alot of numbers there pal
Answer:
The symbol is <, because -11.5 < -9.5
Step-by-step explanation:
The number line is arranged from smallest to greatest numbers, and when you read the numbers you start from left to right, so the numbers in the left are smaller than the number in the right
In the set of the negative numbers, the greatest value is the smallest number
Examples
-1 is greater than -2 because -2 lies before -1 on the number line
∵ The numbers are -11.5 and -9.5
∵ The number -11.5 is before the number -9.5 on the number line
- That means -11.5 is smaller than -9.5
∴ -11.5 < - 9.5
∴ The symbol is <
