Answer:

plz mark brainly

Explanation:

Silicic is an adjective. It is used to describe Magma or Igneous rock. Magma or Igneous rock are rich in silica.Magma is a molten or semi-molten material from which all igneous rocks are derived. It is found beneath the surface of the earth in molten or semi-molten form. When it erupts from a volcano in the form of lava, it flows down, gets cooler and become solid as a rock.Silicic rock usually consists of 63 % of silica. Two common and famous silicic rocks are Granite and Rhyolite.So it is clear from the above given detail that Option a is correct option. Its location is likely underneath an ocean or a mountain. :D :)

A bag contains purple marbles and red marbles, 114 in total. The number of purple
Alex

Answer:

Explanation:

Givens

Purple marbles = P

Red marbles = R

Equations

P + R = 114

P = 5*R + 6

Solution

Put the second equation into the first.

5*R + 6 + R = 114      Combine like terms on the left

6R + 6 = 114              Subtract 6 from both sides.

6R +6-6 = 114-6        Combine

6R = 108                   Divide by 6

6R/6 = 108/6

R = 18

=======================

P+R = 114

P + 18 = 104              Subtract 18 from both sides.

P + 18-18=104 -18     Do the subtraction

P = 86

En un esquema señala cuáles son los diferentes ramas industriales y su importancia
Serhud [2]

La respuesta correcta a esta pregunta abierta es la siguiente.

Las diferentes ramas industriales son las siguientes. Primero, lo que se conoce como la industria básica. Luego, la industria manufacturera y la industria de la transformación. Cuando hablamos de la industria básica estamos hablando de las empresas que se encargan de extraer la materia prima y los recursos naturales, como lo hacen las empresas petroquímicas o las que extraes los metales y minerales de la tierra. Cuando se han extraído los materiales, se mandan a fábricas para que los transformen en productos. Ahí es donde entra la industria de la transformación, que convierte los recursos naturales en textiles. Finalmente la industria manufacturera fabrica la ropa que nos ponemos todos los días. O cualquier otro producto de consumo público.

La importancia de estas industrias es que son vitales para la vida económica de un país. Si no existieran, no habría forma de transformar la materia prima o recursos naturales en los productos que usamos todos los días.

A country with more than one official language may require all public documents to be in all languages. What is an official lang
GrogVix [38]

Answer:

An official language is one which has designated as the main language for business, education, government and administrative affairs.

Explanation:

The official language of a country is not always the most spoken language. Many countries also have multiple official languages.

In the case of Canada, English and French both have official status even though English has more speakers than French at a national level.

An example of a country where a colonial language is used by the government but is not understood by a majority of the population is Senegal. French is the administrative language, but only around one-fifth of Senegalese understand French.

In general, which of the following is true about the effect education has on family size? Check all that apply. A. Less educatio
Scrat [10]

Answer:

B. Less education, earlier marriage, more children.

C. Educated women have fewer children, even after correcting for the fact that they marry later.

D. More education, later marriage, fewer children.

Explanation:

One of the most important factors when it comes to birthrates and thus family size is education. This goes for both genders, though it tends to be more pronounced at the women and their education level. To put it simply, the more educated the population is, the smaller the family size, the less educated the population is, the bigger the family size.

  • When people are less educated, they start working earlier and very often marry very young. By getting married very young they have the first child very early and on top of it, they have much more time to have more children.
  • When people are more educated, they finish studying later, focus on building a career because they have many more opportunities, thus they delay marriage. When they decide to get married it is later in their lives so usually, they don't really have enough time to have larger families.
  • The education level of women is crucial. In every country where the women are highly educated the birthrates have dropped sharply. Basically, when women focus on their careers and delay marriage they found themselves in a situation to have a single child or to miss out on the period when they can have a child thus end up with none.
