Answer:

pronumeral is a letter that is used to represent a number (or numeral) in a problem.

For example, the formula for the area of a rectangle is:

Area of a rectangle = length × width

If A represents the area of the rectangle, l represents the length of the rectangle and w represents the width of the rectangle, then we can write the formula for the area of the rectangle as follows:

A = l × w

In this formula, the letters A, l and w are called pronumerals.

Note:

A pronumeral is a letter used in a problem to represent the measurement of a quantity.  We often choose the first letter of the name of a quantity.

For example, the measurement of the base of a triangle will be represented by b.

Step-by-step explanation:

Figure 1 - Where to find the symbol for applying values to pronumerals.Figure 2 - Applying values to pronumerals command in action.

Please note: The input of a ⇒ 7 will not apply the value to the pronumeral.

Now we can use a in our calculations

To determine to measure of the unknown angle, be sure to use the total sum of 180°. If two angles are given, add them together and then subtract from 180°. If two angles are the same and unknown, subtract the known angle from 180° and then divide by 2.

If the problem did not give you the percentile it would be confusing. You would not know if they wanted money or just a number!!! So it is pretty important.

An automobile firm wants to purchase either machine A or machine B. The intial cost of machines A and B are $40,000 and $50,000,
Fynjy0 [20]

Answer:

C. $118,000 and $110,000, respectively.

Step-by-step explanation:

Please consider the complete question.

An automobile firm wants to purchase either machine A or machine B. The intial cost of machines A and B are $40,000 and $50,000, respectively. The power consumption per year of machines A and B are 120 MWh and 100 MWh, respectively. The power cost is $40/MWh. The estimated operating and maintenance cost over 10 years is $30,000 for machine A and $20,000 for machine B.

First of all, we will find the amount spent on power consumption for 10 years by each machine as:

\text{Machine A}=10\cdot 120(\$40)\\\text{Machine A}=\$48,000

\text{Machine B}=10\cdot \$100(\$40)\\\text{Machine A}=\$40,000

Now, we will find overall cost of machines A and B by adding initial cost, power consumption for 10 years and maintenance cost as:

\text{Overall cost of machine A}=\$40,000+\$48,000+\$30,000

\text{Overall cost of machine A}=\$118,000

\text{Overall cost of machine B}=\$50,000+\$40,000+\$20,000

\text{Overall cost of machine B}=\$110,000

Therefore, the overall cost of machines A and B are $118,000 and $110,000, respectively and option C is the correct choice.
