Answer:
D. 
Step-by-step explanation:
Answer:
60.5 milligrams per square centimeter First, determine how many half lives have expired by dividing the time by the half-life. So: 55/20 = 2.75 That means that only 2^(-2.75) = 0.148650889 = 14.8650889% of the original substance remains. So just divide the amount remaining by 0.148650889 to get the original amount. 9 / 0.148650889 = 60.5445419 So originally, there was 60.5 milligrams per square centimeter 55 years ago.
Answer:
Step-by-step explanation:
The third digit can be 8 6 4 2 or 0
The last digit can be 4 3 2 1 or 0
The second digit 8 4 0 which makes the last digit 2 1 0
The first digit is 3
The choices are
The first digit is 3. That's all you can be sure of. Lets assume zero is not a choice.
3 8 4 2
3 4 2 1
Answer: 5/24
Step-by-step explanation:
First:
Reduce fractions where possible.
Then your initial equation becomes:
5/16 * 2/3
Second:
Applying the fractions formula for multiplication,
5*2 and 16*3 = 10/48
Simplifying 10/48, the answer is
5/24
M=undefined, because it is a vertical line. A horizontal line would be 0.
y-intercept=undefined
equation=x=a(x-intercept)
