Hello.
In order to solve a proportion, you should cross-multiply:
Multiply 7 times 9 and 5 times x:
5x=63
Divide both sides by 5:
x=
Now let's solve the second proportion.
Multiply 8p times 6 and 12 times 15:
48p=180
Divide both sides by 48:
p=3.75
I hope it helps.
Have an outstanding day.
Answer:
3.48 hours
Step-by-step explanation:
The equation is:
Where
M(t) is the amount of medication remaining in mg
t is the time it takes, in hours
The questions asks HOW LONG it will take to make the remaining medication to 1 milligrams (1 mg)??
We have to substitute M(t) with "1" and find the corresponding value of "t". We will use natural log to solve this. Shown below:
<u>Note: </u> Ln(e) = 1
This means, the amount of time it will take is about 3.48 hours
