Step 1: Add 65 to all sides
Step 2: Add 4x to all sides
Step 3: subtract 70 to all sides
Step 4: divide by 4 to all sides
Ending: x is greater than or equal to -17.5
You will end up with it saying -17.5 is greater than or equal to -2.75 but since -17.5 is not greater than -2.75 the answer to this problem is ...
No solution because the inequality that you end up with won't make sense and therefore does not work in the problem
Answer: NO SOLUTION (yayayyayay).
Answer: D. Two or zero
Step-by-step explanation: x=-7/6+-1/6√385
There isn't an exact place you could really solve this number, regardless of the way you break it down
62.5 mg sample will remain after 240 days
Step-by-step explanation:
Given
Half-life = T = 60 days
The formula for calculating the quantity after n half lives is given by:

Here
N is the final amount
N_0 is the initial amount
n is the number of half lives passed
The number of half lives are calculated by dividing the time for which the remaining quantity has to be found by half life
The quantity has to be calculated for 240 days so,

Given

Putting the values in the formula

Hence,
62.5 mg sample will remain after 240 days
