What does it mean to you to be a conservation leader
Anna11 [10]

Answer:

Conservation leadership is a term without a widely shared understanding of its scope and meaning. In this article, the author shares perspectives based on interviews, literature and a survey to begin to identify strategies that define conservation leadership. Results indicate that some elements of conservation leadership are similar to strategies of effective leadership more broadly. Conservation leadership also includes distinguishing aspects, however, such as conflict management and partnership-building.

Tommy and Erin are building a skateboard ramp. They want the ramp to be 3 feet tall and 5 feet long.
BARSIC [14]

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.
