Answer:
t = 6162 years
Step-by-step explanation:
Apparently you are asked to use the constant k = 0.0001 instead of the most common 0.00012. We'll answer the problem using such number you typed, but make sure that there is no omission in your typing.
The equation to use is that for carbon decay:
If the skull contains 54% of its original amount of C14, then that means that :
we use this to solve for the time (t) in our equation:
which rounded to the nearest year as requested gives :
t = 6162 years
Answer:
440
Explanation:
If 50% of the total gum balls are red which is 220, then the other 50% is 220.
The second one is the only equivalent equation. Simply plug in each variable in each equation. And compare!
Answer: 4 or 
To find the square root of a number, remember that there will be two factors that are the same that will give you the product.
Lets start from 1:
1 x 1 = 1
2 x 2 = 4
3 x 3 = 9
4 x 4 = 16
As you can see, 4 x 4 is 16. To make sure I'm correct, remember that a square roots consists two identical factors.
4 and 4 are the same numbers.
Therefore, 
= 4
It can also be written as
For this case we have the following expressions:
70,000,000
7,000,000
If we divide the first expression by the second we have:
Thus, we have that the first expression is 10 times greater than the second expression.
Answer:
70,000,000 is 10 times greater than 7,000,000
