<u>Answer</u>: Fish A because of its elongated body and powerful tail.
<u>Explanation</u>: An elongated body gives the fish a streamlined or fusiform shape. This enables them to slide more esily through water, thus decreasing the energy expenditure of the fish for swimming. Powerfull tails also enables them to swim over long distances as well as bursts of speed. This speed capability is vital when the fish will either try to avoid a predator or, if it is a predator itself, catch its prey.
Answer:
Crater Lake
Crater Lake, Klamath County. Nearly 2,000 feet deep, Crater Lake, in southern Oregon, is the deepest lake in the United States. This must-see Oregon attraction is the result of the ancient Mount Mazama erupting over 7,000 years ago and collapsing into itself.
Himalayas, mountains include amount Everest and K2
Answer: the eastbound train had travelled 12 miles
Explanation: using Pythagoras theorem, we know that
X^2 = a^2 + b^2
Where ^ stands for raised to power.
Let
a stand for the train going towards North and
b stands for the train going towards east.
X stands for the total distance between train a and b = 20 miles.
By Pythagoras rule
X^2 = a^2 + b^2
20^2 = 16^2 + b^2
400 = 256 + b^2 so that
b^2 = 400 - 256 = 144
b = √144
b = 12 miles.
