Merit pay, being performance pay, depends on the employer. Increment in merit pay happens: Option D: whenever your employer decides

What is merit pay?

Merit pay, often known as merit raises or pay for performance, is a type of performance-based pay.

Merit pay, being performance pay, depends on the employer.

Increment in merit pay happens whenever your employer decides. It is because your performance is usually judged by someone, usually employer or a team leader which then reports to the employer usually.

So instead of monthly based increment in the merit pay, the increment happens whenever the employer (or member in power) decides to increase it. So option D is best among all the options.

Thus, increment in merit pay happens: Option D: whenever your employer decides

Step-by-step explanation:

90 degrees
A right angle has a value of 90 degrees (90∘ ). A right triangle is a triangle in which one angle is a right angle. The relation between the sides and angles of a right triangle is the basis for trigonometry. The side opposite the right angle is called the hypotenuse (side c in the figure).

Leo is buying milk for his family for a week. He said he bought 7 kilograms of milk. Is his answer reasonable? Explain.

Answers

Answer:

First, we know that a single liter of milk weighs around 1.032 kg.

Then 7 kilograms of milk is equivalent to (almost) 7 liters of milk.

Now, this is reasonable?

Well, for a typical person, the consumption is between 0.5L and 0.75L

So 7kg of milk may less of what a typical family consumes in a week, but is not an outlier (for example, 30kg of milk or 1kg of milk per week are outliers, which are "nonreasonable") so 7 kg is a reasonable amount of milk.

Now, if the question only refers to the units he used (kg instead of liters) this does not matter, as we know, mass and volume are two different, but equivalent, ways of describing a known matter, as these are related by the density:

Density = mass/volume.

So, for a known material, if you know the mass that you have, you also know the volume.

Then using kg is reasonable in this situation.

A mug is 3/7 full. The mug contains 4/7 of a cup of water. Find the capacity of the mug. Write the answer as a fraction or mixed number in simplest form.

Answers

Answer:

source: https://brainly.com/question/18728451

credit: samueladesida43

hope this helps!

Step-by-step explanation:

7/6 cups of water is the mug's capacity

Step-by-step explanation:

Capacity refers to how much a container can contain.

Let x be the capacity of the mug.

According to the question, the mug is 3/7 full. This means that the mug contains 3/7 × x = 3x/7 of water.

It was further stated that the mug contains 1/2cup of water. This means that:

1/2 cup of water = 3x/7 of water in the mug

Hence;

1/2 = 3x/7

3x × 2 = 7 × 1

6x = 7

x = 7/6

Therefore, the capacity of that mug is 7/6 cups of water.

A fraction is written in the form of a numerator and a denominator where the denominator is greater than the numerator

3/7 of the mug = 4/7 of a cup of water

1 mug = 4/3 of a cup of water

The capacity of the mug is 4/3 of a cup of water.

What is a fraction?

A fraction is written in the form of a numerator and a denominator where the denominator is greater than the numerator.

Example:

1/2, 1/3 is a fraction.

We have,

A mug is 3/7 full.

The mug contains 4/7 of a cup of water.

This means,

3/7 of the mug = 4/7 of a cup of water _____(A)

The full capacity of the mug can be represented by 1

So,

Multiply 7/3 on (A).

7/3 x 3/7 of the mug = 7/3 x 4/7 of a cup of water

1 mug = 4/3 of a cup of water

Thus,

1 mug = 4/3 of a cup of water

The capacity of the mug is 4/3 of a cup of water.

Answer:

constant: 4

coefficent: 7, 18 (However, -1 can also be counted as a coefficient, it is just invisible!)

Step-by-step explanation:

coefficient: a numerical or constant quantity placed before and multiplying the variable in an algebraic expression

therefore, 7 and 18 are coefficients. HOWEVER, -1 can also be a coefficient to -z.

constant: a quantity or parameter that does not change its value whatever the value of the variables, under a given set of conditions.

The solution to the multiplication of surds (2√3) × (3√2) is; 6√6

We want to find; √12 × √18

Let us break each of them into the factors to get;

√12 × √18 = √(4 × 3) × √(9 × 2)

Now,this can be expressed as;

(√4 × √3) × (√9 × √2)

Simplifying this further gives;

(2√3) × (3√2)

Now, in surds, we know that;

a√b × p√q = ap√bq

Applying the surd rule above to our question gives;

(2√3) × (3√2) = 6√6
