Answer:

Option (4)

Explanation:

Water is the most essential element that is required by all living organism. In order to survive, water is needed. Over the years, the use of water has been increasing at a considerably higher rate. At many places, the water level has decreased. This can cause a great problem in the near future as the water on earth is depleting, either by polluting or by making excess use of it.

Currently, water is one of the major resources and one must make limited and proper use of it.

In the United States, a huge amount of water is used for domestic purpose. This includes the water that are usually used for drinking purpose, washing of dishes, toilet flushing, bathing and washing clothes, and so on.

According to the statistical record, it has been noted that in US, the maximum amount of domestic water is used in the toilets.

Thus, the correct answer is option (4).

Bowen’s continuous reaction series describes the crystallization behavior of a singlemineral (with variable chemical composition
FromTheMoon [43]

Answer:

C. plagioclase

Explanation:

From the magma silicate crystals are formed successively when the magma temperature reaches the typical melting temperature for each type of crystal. The first crystals formed at high temperatures can then change their composition or dissolve again. In this way the crystals already formed contribute their ions, molecules and atoms to magma and combine again forming new crystals whose melting temperature is lower than that of the first crystals formed. The new crystals are said to be stable at the lowest temperatures set now. These processes of change are called reactions. As several successive reactions occur as the magma temperature decreases the ordered series of reactions is called the BOWEN series in honor of the Canadian scientist who formulated this concept. There are two types of reactions, the continuous reaction and the discontinuous reaction.

<u> By continuous reaction a crystal formed at high temperatures such as a plagioclase rich in the Ca2 +</u> component gradually varies its composition by replacing a portion of the Ca2 + ions with the Na + ions and a portion of the Al3 + ions with the Si4 + ions. To maintain its neutrality, the replacement of Ca2 + by Na + is coupled with the replacement of Al3 + by Si4 +. The series of continuous reaction starts from the plagioclase rich in Ca2 +, passes through several plagioclase of intermediate composition towards the plagioclase rich in Na +

the average of two number is 55 to subtract from the greater number ratio between number become 1:2 the smaller number is
Thepotemich [5.8K]

Complete question:

The average of two number is 55. If 2 is subtracted from the greater number, the ratio between the numbers become 1:2 . The smaller number is

Answer:

The smaller number is 36

Explanation:

let the smaller number = x

let the greater number = y

\frac{x + y}{2} = 55\\\\

x + y = 110

y = 110 - x --------- equation (i)

\frac{x}{y-2} = \frac{1}{2}\\\\ y-2 = 2x\\\\y = 2x + 2 ------equation(ii)

Substitute y in equation (ii)

110 - x = 2x + 2

110 - 2 = 2x + x

108 = 3x

x = 108 / 3

x = 36

Therefore, the smaller number is 36

In rare occasions, contour lines can intersect one another on a topographic map.
iris [78.8K]

Answer:

False

Explanation:

Contour lines can never cross one another. Each line represents a separate elevation, and you can't have two different elevations at the same point.

Hope this helps!
