Answer:
0u
7u
6u
2u
Step-by-step explanation:
All of these question are just a matter of adding like terms
For the first one we have
7u+(-u)+(-6u)
which is equal to
7u-u-6u
Which I'm sure you can see is equal to 0 or 0u
10/2u+2u
10/2u=5u
5u+2u=7u
6u+0u
0u=0
6u
6u+(-4u)
6u-4u
2u
(-1-7) = -8
-8^2 = 64
9-5 = 4
64/4 = 16
6,559,595 pegs x 4 colors = 26,238,380
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
