Sorry I just need points so I can have it on the phone later after work and I will have to go get it bruh was a day and a half day
Answer:
8
Step-by-step explanation:
we have to give the smallest number that will divide by 12
if we give 1 it will be 79 and this number won't divide to 12
so the second smallest number would be 2 and the answer will be 78 and this doesn't divide by 12 also, when we try all the numbers we can see at last that the smallest number we can give is 8 which will be 72 and this number can also be divided by 12
Answer:
It will take approximately 3.34 hours for the drug to decay to 90% of the original dosage
Step-by-step explanation:
As suggested, we use the formula for exponential decay:
From the given information, the half life of the drug in blood id 22 hours, so that means that it takes that number of hours to go from the initial value , to a final value equal to . Using this information we can find the decay rate "k" by solving for this parameter in the formula, and using the natural log function to bring the exponent down:
Now we use this value for the decay rate "k" to calculate how long it would take to decay to 90% of the original dose;
The answer is 90/100 and it would simplify to 9/10
3+3/5 over 4 is how you start
So 12*1.5 gets you 18 so u mutiply 7*1.5 and get 10.5 but you will have to round so the answer would be 11
