8. Son las actividades que consisten en la transformación de la materia prima en productos elaborados o manufacturados.​
LuckyWell [14K]

Answer:

Actividades industriales.

Explanation:

La industria es la parte de la economía que produce bienes y proporciona servicios, a partir de la modificación de las materias primas obtenidas de la naturaleza.

La industria se puede dividir en cuatro partes. La primera parte son las industrias donde los recursos naturales se convierten en productos como la minería, la tala y la agricultura. La segunda parte son las industrias en las que las materias primas se convierten en productos, como la automoción y la siderurgia. La tercera parte son las industrias de servicios como el comercio y la banca. La cuarta parte es la investigación, el diseño y el desarrollo que pueden conducir al cambio y al progreso tecnológico. Los países en desarrollo suelen tener economías basadas más en la primera y segunda partes, mientras que en los países industrializados se pone más énfasis en la tercera y cuarta partes que en los países en desarrollo.

You're building a 12 foot ramp to the entrance of a building 3 feet above the ground. The ADA regulations require the incline of
Natalija [7]

Answer:

Explanation:

We can assume that:

the 12 foot ramp to the entrance of a building is the base of a right angled triangle and the  3 feet above the ground should be the height above the ground basement. The by using the tangent of a triangle from the knowledge of our trigonometric function; we have:

\mathbf{tan  \ \theta = \frac{opposite}{adjacent}}

\mathbf{tan  \ \theta = \frac{3}{12}} \\ \\ \mathbf{tan  \ \theta = 0.25 } \\ \\ \mathbf{\theta = tan^{-1} (0.25)} \\ \\ \mathbf{\theta = 14.04^o}

The degree measure of the angle of elevation is 14.04°

NO, it doesn't fit the requirements.

We can increase the foot ramp to 34 feet instead of being the 12 given value in order to fit the requirements.
