121.3 grams of caffeine is remaining in her blood
<h3>How to determine the amount of caffeine?</h3>
The given parameters are:
- Initial, a = 175 mg
- Rate, r = 11.5%
- Time, t = 3 hours
The amount of caffeine is calculated as:
A(t) = a(1 - r)^t
This gives
A(t) = 175 * (1 - 11.5%)^t
At 3 hours, we have:
A(3) = 175 * (1 - 11.5%)^3
Evaluate
A(3) = 121.3
Hence, 121.3 grams of caffeine is remaining in her blood

200 has the same value as 20 tens beucase 20*10=200
X(^-1)^7=x^6
7(c^1)^2/3=7(c)^2/3
(m^2n^3)^-3=1/m^6n^9
Answer: 11
Step-by-step explanation: The sum of 15 and six times t will be 15 + 6t = 81.
Now, you subtract 15 from both sides to isolate the constants from the variables on the left side and on the other side and you will end up with 6t = 66. Then, you divide 6 from both sides to finally isolate the numbers from the variable and 66 divided by 6 would equal 11
Hope this Helps :)
You have to turn the number or ratio and simplified the number and put it in to the chart like the norm number
