The annual maintenance collected in 2014 will be $1,750,000.

To calculate the annual maintenance collected in 2014, we need to find the number of customers who will renew their maintenance contract and the number of customers who will pay for maintenance as a percentage of product sales in 2013.

Number of customers renewing maintenance in 2014 = 80% of $2,000,000 = $1,600,000

Number of customers paying for maintenance in 2014 = 75% of $2,000,000 = $1,500,000

So, the total annual maintenance collected in 2014 will be:

$1,600,000 + $1,500,000*10% = $1,750,000

Therefore, the annual maintenance collected in 2014 will be $1,750,000.

The number of times the digit '3' is needed to label the gym lockers numbered from 1 to 99 is 20 times.

We can analyze the pattern of numbers from 1 to 99 to determine the frequency of the digit '3'.

From 1 to 9, there is only one number that contains the digit '3', which is 3 itself.

Therefore, there is one occurrence of '3' in this range.

From 10 to 19, there are ten numbers, and only one of them, 13, contains the digit '3'.

From 20 to 29, there is only one number that contains the digit '3', which is 23.

From 30 to 39, there are ten numbers, and each one of them contains the digit '3'.

Following this pattern, we can see that the digit '3' appears 20 times between 1 and 99.

Hence, we need the digit '3' a total of 20 times to label all the gym lockers numbered from 1 to 99.

Step-by-step explanation:

The statement in if-then form is option a. If x = 8, then x2 - 3x = 40.

Expressions are statements consisting of two or more terms and terms are connected to each other using mathematical operators like addition, multiplication, subtraction and so on.

The given statement is,

For x = 8, x² - 3x = 40.

We have to rearrange this in if - then form.

If we have the quadratic equation,

x² - 3x = 40

x² - 3x - 40 = 0

(x - 8) (x + 5) = 0

So x = 8 or x = -5

So we cannot say that if x² - 3x = 40, x = 8, because there is a chance for -5 also.

If x = 8, then x² - 3x = (8)² - (3 × 8) = 40

Hence the correct option is a. If x = 8, then x2 - 3x = 40

Step-by-step explanation:

The speed of red light in crown glass is approximately 1.99 x \(10^8\) m/s.

a. The speed of violet light in crown glass can be calculated using the formula:

v = c/n

Where,

v is the speed of light in the material,

c is the speed of light in vacuum and

n is the index of refraction of the material for violet light.

Plugging in the values given, we get:

violet light speed in crown glass = c/n

violet light speed in crown glass = c/1.53

Using the value for the speed of light in vacuum,

c = 3.00 x \(10^8\) m/s,

We can calculate the speed of violet light in crown glass as:

violet light speed in crown glass = (3.00 x \(10^8\) m/s) / 1.53

= 1.96 x \(10^8\) m/s

Therefore, the speed of violet light in crown glass is approximately 1.96 x \(10^8\) m/s.

b. Similarly, the speed of red light in crown glass can be calculated using the same formula, but with the index of refraction for red light:

red light speed in crown glass = c/n = c/1.51

Using the same value for the speed of light in vacuum and plugging in the value for the index of refraction for red light, we get:

The red light speed in crown glass = (3.00 x \(10^8\) m/s) / 1.51 = 1.99 x 10^8 m/s

· Definition of Percentages

Mathematically, percentages are either numbers or ratios that are expressed as fractions of 100. They are usually denoted as "%" or simply "percent." They may be further represented as simple fractions or as decimal fractions. An example of a percentage is 65% or 65 percent.  The term percentage was formed from two words, “per” and “cent.” Cent is a word with Latin and French origin that means "hundred," and "percent" means "per hundred." For example, 90 percent (or 90%) means 90 out of 100 while 50 percent (or 50%) means 50 out of 100 or half of a whole.

1. Determine the initial format of the number to be converted to a percentage

The number to be converted to a percentage can either be in the decimal or fraction format. A good example of a decimal number is 0.57, which may be the calculated ratio of the values you are comparing, while an example of a fraction is 3/20. The initial format will determine the next mathematical process to be carried out on the number.

2. Carry out a mathematical process on the number to be converted to a percentage

If the number to be converted to a percentage is a decimal number like 0.57, you may not need to do anything to it before you go to the next step. However, if it is a fraction like 3/20, you should first divide the numerator (3 in this case) by the denominator (20 in this case) to get a decimal number.

3. Multiply the result of the mathematical process by 100

If you are required to convert a decimal number like 0.57 to a percentage, you are to simply multiply it by 100. That is, 0.57 x 100 = 57. Therefore, 0.57 as a percentage = 57% or 57 percent. Another example of converting a decimal to a percentage is 0.03 x 100 = 3% or 3 percent.

However, if you are required to convert 3/20 to a percentage, you should divide 3 by 20 = 0.15. Then multiply 0.15 by 100 = 15% or 15 percent.

Another example is if you are to convert 5/10 to a percentage, you should divide 5 by 10 = 0.5. Then, multiply 0.5 by 100. Therefore, 0.5 x 100 = 50% or 50 percent.

3. A graph through the indicated point with a slope of -2.

Answer:

c. the lines are the same

Step-by-step explanation:

A system of linear equations has an infinite number of solutions because the lines are the same. The correct answer would be an option (C).

A linear equation is defined as an equation in which the highest power of the variable is always one.

If a system of linear equations has an infinite number of solutions, it means that the equations are equivalent and represent the same line in the coordinate plane.

Therefore, the graphs of the two equations will be the same line, meaning that the lines are coincident. They won't intersect at one point, nor will they be parallel, as the definition of an infinite number of solutions is that they are the same line. And they can be graphed, as they represent a single line in the coordinate plane.

Hence, the correct answer would be option (C).

The volume of the described solid is (490/7) π h^3.

The formula for the volume of a right circular cone is:

V = 1/3 πr^2h

In this case, the cone has height 4h and base radius 7r. We need to express the volume in terms of h and r. Since the base radius is 7r, we can write:

r = (1/7) b

where b is the radius of the base of the cone. To find b, we use the fact that the height of the cone is 4h and the base radius is 7r:

h^2 + r^2 = (4h)^2

Substituting r = (1/7) b, we get:

h^2 + (1/49) b^2 = 16h^2

Solving for b, we get:

b^2 = 49(16h^2 - h^2) = 49(15h^2) = 735h^2

Therefore, b = sqrt(735)h, and the volume of the cone is:

V = 1/3 πr^2h = 1/3 π(49/49) b^2 (1/7) 4h = (2/21) π (735h^3)

Simplifying, we get:

V = (490/7) π h^3

Therefore, the volume of the described solid is (490/7) π h^3.

Answer: The weight of one person is 22 units and the other is 110 units.

Step-by-step explanation:

Let x = weight of one person, then the weight of the other person = 5x

According to the question,

Sum of weight of both persons = 132

⇒ x+ 5x = 132

⇒ 6x = 132

Divide both sides by 6 , we get

x= 22

Other [person's weight = 5(22) = 110 units.

To calculate the strategy gap, operations gap, and total gap, we need to compare the expected sales targets with the actual sales achieved

The gap analysis graph would display the expected sales targets for each objective and compare them to the actual performance. The y-axis represents the sales in millions of pounds, and the x-axis represents the planning period from 2016 to 2019. Each objective's expected sales target would be plotted as a line, and the actual sales achieved would be plotted as a separate line. The gaps between the two lines would indicate the variance between expectations and performance.

To calculate the strategy gap, operations gap, and total gap, we need to compare the expected sales targets with the actual sales achieved. The strategy gap represents the variance between the target sales and the actual sales for each objective. The operations gap reflects the overall variance between the total expected sales and the actual sales achieved. Finally, the total gap would be the sum of the strategy gap and operations gap.

To formulate the corporate objective statement for Lush in 2019, we consider the net profit and total assets. Since the net profit is 10% of sales, we can calculate the net profit as 0.1 multiplied by the actual sales achieved in 2019. Given that the assets are 1000m, the corporate objective statement could be formulated as follows: "Lush aims to achieve a net profit of [calculated net profit] and maintain its total assets at 1000m in 2019, while continuing to expand its product offerings and market share."
