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
D sorry if I am incorrect
Answer:
31,692 inches
Step-by-step explanation:
The length that Marc travelled with his bike can be calculated by the product between the number of rotations of the tire and the circunference of the tire.
So, calculating the circunference of the tire, we have:
C = pi*diameter = pi*26 = 81.68 inches
If in each rotation of the tire, the length travelled is 81.68, the total length travelled is:
Length = number of rotations * C = 388 * 81.68 = 31,691.84 inches
Rounding to the nearest inch, we have Length = 31,692 inches
The correct answers are 2h-2=92 and h-2=92-h.
Explanation:
Hannah, h, is the older sibling and their ages are consecutive odd integers. This means that Anthony's age will be 2 less than Hannah's, or h-2.
The sum of these would be h+(h-2), giving us the equation h+(h-2)=92.
Combining like terms we would have the first correct choice, 2h-2=92.
Our first equation can be transformed, however, to have (h-2) by itself. To do this, we would subtract h from both sides, giving us h-2=92-h.
Hope this helps!
The slope is -2 as for the equation it would be y=-2x
