Answer:

a. SAR is the Sodium adsorption ratio of the water used for irrigation purpose. SAR is ratio of sodium concentration to that of calcium and magnesium concentration.This value is also useful while managing soils that have high concentration of sodium which can occur naturally in some soils.  Although sodium is a macro-nutrient for plants, higher concentration of sodium can cause the displacement of the calcium and magnesium ions in soil which can affect the soil structure by preventing aggregation of clay in the soil resulting in a decrease in the infiltration rates.

b. EC is the electrical conductivity of the soil which depends on the salinity of the soil. High salinity means more solutes in water and this increases the osmotic potential of the soil solution making it difficult for plants to absorb water.

morpeh [17]

Answer:

1,231,000 units

Explanation:

Given that,

Fixed costs = $274,950

Selling price = $9.30 per unit

Unit variable cost = $7.85

Target net income = $1,510,000

Contribution margin:

= Sales per unit - Variable cost per unit

= $9.30 - $7.85

= $1.45

Target Contribution margin:

= Fixed costs + Target income

= $274,950 + $1,510,000

= $1,784,950

Units to be sold:

= Target Contribution margin ÷ Contribution margin

= $1,784,950 ÷ $1.45

= 1,231,000 units

The <u>"tonic" </u>is the first and central note of a scale. the principle of organization around a central note is called  <u>"tonality."</u>


Tonic refers to the primary note of a scale that the scale depends on, sometimes called the root.  

Most tunes begin and end with a similar tone which is the primary note, or tonic, in the scale. At that point you play notes from a scale you could hear that the music appears to float towards the main note, it resembles somewhere in the range of pressure is left until the point when you have achieved that first note. This phenomenon is called tonality.

If the european subsidiary of a u.s. firm has net exposed assets of 200,000, and the euro increases in value from $1.22/ to $1.2
Leona [35]

If the European subsidiary of a US company has published net assets of €200,000 and the euro rises from $1.22/€ to $1.26/€, the US company would incur a loss of $8,000 in translation.

In the corporate world, a subsidiary is a company that belongs to another company, usually called a parent company or holding company. The parent company retains control of the subsidiary. That is, the parent company owns or controls more than half of its shares.

A European company – also known as SE  – is a type of public limited company that allows a single set of rules to operate in different European countries.

In accordance with the principle of balance, the content and form of EU action must not exceed what is necessary to achieve the objectives of the Treaty. Page 3. 3. Subsidiarity is who should act. Proportionality is about the types of measures that should be implemented.
