Answer:
Step-by-step explanation:
<u>The difference of −2d and −3d is equal to the difference of 1/6 and 1/3</u>
- -2d - (-3d) = 1/6 - 1/3
- -2d + 3d = 1/6 - 2/6
- d = -1/6

Answer:
7371 years
Step-by-step explanation:
The half-life of Carbon-14 is reportedly about 5730 years. Then the exponential decay equation can be written as ...
f = (1/2)^(t/5730)
where f is the fraction remaining after t years.
Taking logarithms and solving for t, we find ...
log(f) = (t/5730)log(1/2)
t = 5730·log(f)/log(1/2)
For the fraction f = 0.41, the age is approximately ...
t = 5730·log(0.41)/log(1/2) ≈ 5730·1.286304 ≈ 7371 . . . years
The age of the skull could be estimated to be 7371 years.

Answer:
x=10 , y=7
Step-by-step explanation:
x + y = 17
we know that ducks has 2 feet and sheep has 4 feet.
so, 2x + 4y = 48
x = 17 -y
2(17-y) + 4y = 48
34 - 2y + 4y = 48
2y = 48 -3 4
2y =1 4
y=7
x + 7 = 17
x = 17-7
x=10
You need to get the decimeters converted to feet or the 5.5 feet to decimeters which are :
5.5 ft= 16.76 decimeter
590.5 decimeters= 193 feet
I like the decimeters better then you will take 590.5 / 16.76 = 35.23 decimeters
