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.
They provide evidence that movements of the crust are a result of slow moving currents in the mantle. Since earthquakes and volcanic eruptions are usually a result of stick-slip movements between 2 more plates and it is tension changes that are responsible for this sudden movement, the plates must be moving overtime or this tension would remain fairly constant.
Answer:
b. Providing habitats for wildlife
Explanation:
<em>Dead trees and down wood provide wildlife habitat it is estimated that 2/3 of all wildlife use them at least during one point of their life cycle.</em> They also serve to cycle nutrients, decreasing erosion, etc.
I hope you find this information useful and interesting! Good luck!
I’m not entirely sure what you mean. You ask for AC but give AC as 4(x+2).
