A rhombus is a parallelogram.
A rhombus has two sets of parallel sides.
A rhombus has four sides of equal length.
A rhombus has four right angles.
Answers
Given:
Consider a rhombus.
To find:
Which of the given statements about a rhombus is not true?
Solution:
Properties of a Rhombus:
1. It is a quadrilateral which is a special case of a parallelogram.
2. It has four equal sides.
3. It has two sets of parallel sides.
4. Opposite angles are equal.
5. Diagonals are perpendicular bisectors.
Since a rhombus doesn't has four right angles, therefore the last statement in the given options is not true about the rhombus.
Hence, the correct option is D.

Which inequality is true
Answers
The first one on the left.
The vertical bars mean we take the absolute value of that number.
Absolute value means distance from zero on a number line.
So the absolute value of any number
is the positive version of that number.
So for the one on the left we have |-100| > |50|.
Since absolute value represents the positive version
of a number, the absolute value of -100 will be 100.
Since |50| is already positive, it stays the same.
So we have 100 > 50 which is indeed a true statement.
If you solve the other ones, you will see that they are false.

explain which properties of equality you used when solving the equation from part a to determine the mystery weight.
Answers
To solve the equation in part a and determine the mystery weight, we used the following properties of equality:
Addition property: This property states that if we add the same number to both sides of an equation, the equality is preserved. In this case, we added 23 grams to both sides of the equation to isolate the variable.
Subtraction property: This property states that if we subtract the same number from both sides of an equation, the equality is preserved. In this case, we subtracted 8 grams from both sides of the equation to isolate the variable.
Multiplication property: This property states that if we multiply both sides of an equation by the same number, the equality is preserved. In this case, we multiplied both sides of the equation by 3 to isolate the variable.
Division property: This property states that if we divide both sides of an equation by the same number (excluding 0), the equality is preserved. In this case, we divided both sides of the equation by 2 to isolate the variable.
By using these properties of equality, we were able to manipulate the equation and isolate the variable to determine the mystery weight.

Standard automobile license plates in a country display 1 numbers, followed by 2 letters, followed by 4 numbers. How many different standard plates are possible in this system
Answers
There are 6,760,000 different standard license plates possible in this system.
To determine the number of different standard license plates possible in the given system, we need to consider the number of options for each component of the license plate.
1. Numbers (first digit): The first digit can be any number from 0 to 9, so there are 10 possible options.
2. Letters (2 letters): Each letter can be any uppercase letter of the alphabet.
There are 26 letters in the English alphabet, so there are 26 options for each letter. Since we have two letters, the total number of options for the letters is 26 * 26 = 676.
3. Numbers (4 digits): Each digit can be any number from 0 to 9, so there are 10 options for each digit. Since we have four digits, the total number of options for the numbers is 10 * 10 * 10 * 10 = 10,000.
To find the total number of possible license plates, we multiply the number of options for each component:
Total number of license plates = (Number of options for numbers) * (Number of options for letters)* (Number of options for numbers)
Total number of license plates = 10 * 676 * 10,000
Total number of license plates = 6,760,000

What is the project's NPV? Would you recommend purchasing the ranch? Briefly explain.
Answers
Information is needed to evaluate the project's financial viability, considering factors such as the initial investment, expected cash flows, cost of capital, and project duration.
To calculate the year 1 operating cash flows (OCF), we need to subtract the year 1 costs from the year 1 revenues:
OCF = Year 1 Revenues - Year 1 Costs
OCF = $192,000 - $125,000
OCF = $67,000
To find the depreciation expense in year 3, we need to determine the depreciation method. The provided information is incomplete regarding the depreciation method, so we cannot calculate the depreciation expense in year 3 without knowing the specific method.
The change in Net Working Capital (NWC) in year 2 can be determined by multiplying the Net Working Capital percentage (given as a percentage of t+1 revenues) by the year 1 revenues and subtracting the result from the year 2 revenues:
Change in NWC = (Year 2 Revenues - Net Working Capital percentage * Year 1 Revenues) - Year 1 Revenues
Without the specific Net Working Capital percentage or Year 2 Revenues values, we cannot calculate the exact change in NWC in year 2.
The net cash flow from salvage (ATSV) is calculated by multiplying the Salvage Value percentage by the Initial Cost:
ATSV = Salvage Value percentage * Initial Cost
ATSV = 28% * $390,000
ATSV = $109,200
To calculate the project's NPV, we need the cash flows for each year, the cost of capital, and the project duration. Unfortunately, the information provided does not include the cash flows for each year, so we cannot calculate the project's NPV.

Use calculus to find the area of the triangle with the given vertices: (0,0) (2.8) (5,6)
Answers
The area of the triangle with the given vertices is 6.6.
The formula for finding the area of a triangle given its vertices is A = 1/2 abs(x1y2 + x2y3 + x3y1 - x2y1 - x3y2 - x1y3). To calculate the area of the given triangle, we substitute the coordinates of each vertex into the formula. First we find the three cross-products: x1y2 = 0 * 6 = 0, x2y3 = 2.8 * 6 = 16.8, and x3y1 = 5 * 0 = 0. Then, we find the two products of the y-coordinates: x2y1 = 2.8 * 0 = 0, and x3y2 = 5 * 6 = 30. Lastly, we find the product of the x-coordinates: x1y3 = 0 * 6 = 0. Adding all these up, we get 0 + 16.8 + 0 - 0 - 30 - 0 = -13.2. We then take the absolute value of the result, abs(-13.2) = 13.2. Finally, we multiply the result by 1/2 to get the area of the triangle, A = 1/2 abs(-13.2) = 1/2 * 13.2 = 6.6. Therefore, the area of the triangle with the given vertices is 6.6.

The probability of picking the letter "I" from the box containing all the letters that form the word "Equilibrium" is 3/11 or approximately 0.273 (27.3%). This is calculated by dividing the number of desired outcomes (3 occurrences of "I") by the total number of possible outcomes.
In order to calculate the likelihood of selecting the letter "I" from a box containing all the letters that make up the word "Equilibrium," we must take into account how frequently the letter "I" appears in the word. Three times in the word "Equilibrium" is the letter "I." The total number of outcomes is equal to the number of letters in the word, which is 11, because each letter in the box has an equal chance of being chosen. As a result, it is easy to determine the likelihood of selecting the letter "I" by dividing the number of desired outcomes (3 desired outcomes) by the total number of available outcomes (11).As a result, the likelihood of selecting the letter "I" is 3/11, which is equivalent to about 0.273 or 27.3%.

If all three corresponding sides and all three corresponding angles are equal in size, two triangles are said to be congruent. Slide, twist, flip, and turn these triangles to create an identical appearance. They are in alignment with one another when moved. A term used to describe an object and its mirror counterpart is congruence. If two things or shapes superimpose on one another, they are said to be congruent. They are identical in terms of size and shape. Line segments having the same length and angles with the same measure are congruent in the context of geometric figures.
