'nine less than three times a number is negative twenty-one.'
Answer:
Yes it is . Just say ratio A is 1:3 and ratio B is equal to that so just say it’s 3:9. Then ratio C is equal to B so just say it’s 9:27. Well 9:27 is equal to 1:3 or in other words A=C
Step-by-step explanation:
Use the compound interest formula: A=P(1+i)^t.
P is the initial amount of the drug, 0.3ml.
i is - 0.0035.
t is in seconds.
You'll get:
A=0.3(1-0.0035)^t.
Sub in any value on t to find out how many ml are left t seconds after injection.
The 0.65 second injection time does not seem to be relevant as the question clearly states that the exponential decay starts AFTER the injection is completed.
The answer to this question is 7,500
