Answer:
Zicrons
Explanation:
The oldest of the zircons in the study, which came from the Jack Hills of Western Australia, were around 4.3 billion years old—which means these nearly indestructible minerals formed when the Earth itself was in its infancy, only roughly 200 million years old.
B. Natural selection and Evolution both show the change over time in the survival of a specific organism. Natural Selection chooses traits that correspond the best with the ecosystem, while evolution gradually changes the species as a whole to cope with the surroundings.
We know that the sum of the interior angles of every triangle is 180°:
( 15 y + 9° ) + ( 22 y + 8° ) + ( 14 y + 10° ) = 180°
15 y + 22 y + 14 y = 180° - 9 ° - 8° - 10°
51 y = 153°
y = 153° : 51
y = 3°
∠ V = 15 · 3° + 9° = 54°
∠ U = 22 · 3° + 8° = 74°
∠ W = 14 · 3° + 10° = 52°
Let`s assume that opposite the angles V, U and W are sides v , u and w. Opposite the smallest angle is the smallest side of a triangle.
Answer: Side length w is the smallest.
Answer:
I believe it is D
Explanation:
Scientists cut open ice cores to look at gases to see the gas concentration and therefore the climate change
