Answer:

A altura aproximada da árvore é 7,9 metros.

Esta questão está relacionada com a proporcionalidade entre variáveis. A proporção é um valor referente a razão de dois números. Por isso, a proporção está atrelada a fração, onde temos um numerador e um denominador. Desse modo, temos uma relação de equivalência entre dois valores.

Nesse caso, vamos resolver o problema por meio da semelhança entre triângulos. A semelhança entre triângulos ocorre quando existem dois ou mais triângulos com mesmos ângulos internos. Desse modo, existe uma proporção entre suas medidas, que devem ser equivalentes sobre uma determinada razão. Portanto:

How is continental movement measured?
yulyashka [42]

Answer:

Explanation:

Geodesy, the science of measuring the Earth's shape and positions on it, allows the measurement of plate motion directly using GPS, the Global Positioning System. This network of satellites is more stable than the Earth's surface, so when a whole continent moves somewhere at a few centimeters per year, GPS can tell.

GPS uses a system of satellites to triangulate the position of a receiver anywhere on Earth. By using a network of receivers near plate boundaries, scientists can very accurately determine how the plates behave

What benefits can countries gain by adopting the practices of the International Model Forest Program?
Nonamiya [84]

The countries that adopt the International Model Forest Program will benefit from sustainable forest management.

Explanation:

The International Model Forest Program is a program that promotes sustainable forest management, thus the countries that adopt benefit from developing sustainable forest management. This is excellent from several different perspectives, such as:

  • recreation
  • economy
  • ecology
  • biodiversity

If the forests are sustainable, than it means that they will be able to prosper, thus maintaining their well being, as well as the well being of the communities of animals and plants in them. Also, this means that there can be economic benefits without destroying the forests, and this can be done by planting new saplings on the places were trees have been cut, and also by gathering forest fruits, herbs, and mushrooms.

The recreation part is too very important. The people will have a beautiful place in nature for recreation, where they can relax and enjoy, have fresh air, and educate themselves about nature first hand.
