(27x + 16*8)/x+8 = 19
(27x +128) /x+8 = 19
multiply both sides by x+8
27x+128 = 19x +152
subtract 19x from both side:
8x +128 = 152
subtract 128 from both side:
8x = 24
divide both sides by 8
x = 24 /8
x = 3 pounds
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
So 1 quater is 25 cents each. 5 quaters would be 125 cents. We know that 4 quaters equal $1.00 So we now have 1 quater left, you can add 25 cents to one dollar and get $1.25
So we started off with 125 cents so we added in a decimal point and added in a dollar sign. Hope this helps.
