Answer:
Fossil B belongs to the same period as the trilobite.
Explanation:
The Law of Superposition states that the youngest rocks will always be found on top of older rocks. So as you dig deeper and deeper, the rocks you find will be older and older.
An illustration of the problem:
<em>----------------------------------------------------------------------------</em>
Fossil C: Two Semi-circles (<u>Top</u> Layer = <em>Youngest</em>)
-----------------------------------------------------------------------------
Fossil B: Rhombus with Diagnonal & <em>Trilobite</em> (<u>Middle</u> Layer)
------------------------------------------------------------------------------
Fossil A: Shaded Rhomboid (<u>Bottom</u> Layer = <em>Oldest</em>)
So, Fossil A is older than both B and C, or, B and C are both younger than A.
Fossil B is Younger than Fossil A, but older than Fossil C.
Fossil C is the youngest (because its on top).
Answer:
x=-16/3 and y =47/6
Explanation:
Subtract the 2 equations to eliminate the variable y
2x+2y=5
-(5x+2y=-11)
---------------
-3x=16
Divide by -3 on both sides
x= -16/3
Plug -16/3 in for x in the first equation to find y
2x+2y=5
2(-16/3)+2y=5
Multiply
-32/3+2y=5
Add 32/3 to both sides
2y=47/3
Divide both sides by 2
y=47/6
x=-16/3 and y =47/6
Hope this helps! :)
Hey there!
Answer: <span> Pampas
Roland should start a cattle ranch in the </span> Pampas as they are very fertile lands which cover over 750,000 km². This area has a mild climate and has a precipitation rate of only about 600 to 1200 mm per year. This area also consists of different and unique wildlife mainly because of the terrains surrounding this place.
Thank you!
