Answer:
One way that glaciers change the landscape is by erosion. As they pass over the ground, the ice scrapes up soil and rock. A valley glacier will leave a valley much deeper, as it erodes the underlying surface with plucking and abrasion.
<span>When
the water level of a stream or river exceeds its natural banks, it has reached
its flood stage. This is a real panic stage for people living nearby the rivers
and streams that has overflowed its natural banks. This flood situation can
destroy any city or village and also drastically impact the financial situation
of the area. Most cities and states move their citizens away from the river
banks before it reaches this danger stage. Before the emergence of
technological advancement, historical evidence proves that many great cities
were destroyed due to such situations. <span /></span>
Answer:
Full question is attached.
Tommy's reasoning is wrong because the hypotenuse is not 5 feet.
A skateboard ramp resembles a right angles triangle so its sides resemble that of a right angled triangle.
The height of 3 feet would be the height of the triangle.
The length of 5 feet would be the length of the triangle.
The piece of plywood that would cover the top of the frame would be the hypotenuse.
In using the Pythagoras rule, the c is the hypotenuse but Tommy made the mistake of assuming that the hypotenuse was b which is where the error came from.
Instead of solving for b, they should have been solving for c which is the hypotenuse.
a² + b² = c²
3² + 5² = c²
9 + 25 = c²
c² = 34
c = √34
c = 5.83 feet
They should use a plywood of 5.83 feet not 4 feet.
