The third one C because .07 is just 7 9/100 is 9 and then 5/8 is around .50 then .75
Answer: 54678 years
Step-by-step explanation:
This can be solved by the following equation:
(1)
Where:
is the quantity of atoms of carbon-14 left after time 
is the initial quantity of atoms of C-14 in the mammal hide
is the rate constant for carbon-14 radioactive decay
is the time elapsed
On the other hand,
has a relation with the half life
of the C-14, which is
:
(2)
Substituting (2) in (1):
(3)
Applying natural logarithm on both sides of the equation:
(4)
(5)
Isolating
:
(6)
(7) This is the age of the mammal hide
13/3>17/4
3/16<6/31
7/11<9/13
Hope this helps!
Answer:
x = 46
Step-by-step explanation:
Here, we want to get the value of the angle marked x
From the diagram given , the two angles that are other than x can be gotten from the value of their supplements
Angles on a straight line are supplementary as they add up to 180
Thus, mathematically;
(180-130) + (180-96) + x = 180
50 + 84 + x = 180
x = 180-50-84 = 46
