How do you do inequalities?

Set up the problemWhen dealing with inequalities, the point of the problem is to get the variable by itself on one side of the equation. A standard example of an inequality is 4 - 2X > 14. This equation is relatively straightforward but provides good examples of the types of issues dealt with when solving inequalities.Remove the constant valueAdding and subtracting to remove the constant value is an easy and safe way to make the problem more manageable and to allow further advancement. In the example equation, start by eliminating the 4 from the variable side of the equation by subtracting 4 f..

What is the importance of geometry?

Math is an abstract field, but it often must be used in physical objects. Geometry provides a means of applying mathematical ideas to construction, vehicles and virtually all objects. When studying how strong a building's support will be, architects must use geometric reasoning. Similarly, geometry allows airplane designers to measure how aerodynamic a particular design is.\nGeometry was essential for developing modern mathematics. The ancient Greeks studied geometry extensively, and many modern algebra theorems and axioms have their roots in Greek geometry. The Greeks also used proofs wi..

Where can you find a 100 x 100 multiplication chart?

The NCalculators chart is scrollable. Clicking on a red number that begins a column or row brings up a multiplication chart for that number, though it only goes up to 50. Clicking on 86 brings up a chart showing 86 x 0 through 86 x 50. Users can enter two numbers to create their own multiplication charts, which they can then print or view as PDFs. BestTimesTable offers a game in which players must look up solutions to problems such as 35 x 53.\nUsers can show or hide numbers in HelpingWithMath's chart to make it easier to view. The website also offers worksheets, flashcards and other math..

What do mechanics use a CanOBD2 code reader for?

While most vehicles indicate to the driver that something is wrong via a light such as “Check Engine” or “Service Engine Soon,” a vehicle enabled with an onboard diagnostic system can also report issues via diagnostic trouble codes. Scanning devices read these codes and use the data to determine the exact state of a vehicle’s mechanical and electronic systems. This allows a mechanic to perform an accurate electronic diagnosis on a potential customer’s vehicle without having to do too much manual troubleshooting.\nDiagnostic trouble codes are alphanumeric codes that report issues an..

What is the volume of a cylinder?

The formula to find the area of the circular base of a cylinder is Pi, approximately 3.142, multiplied by the squared radius of the circular base. The units used to measure the radius and height of the cylinder need to be the same. Converting the units is necessary if they don't match up.\nThe radius is found by drawing a line segment from the center of the circle out to perimeter.

How are fractions used in real life?

An example of one of the most common everyday fractions is a pizza. A pizza is traditionally cut into eight pieces, meaning each piece is 1/8 of a whole pie, and two slices would be 1/4 of the pie. Fractions are also used in cooking measurements, such as 1/2 cup of sugar or 1/4 teaspoon of cinnamon. Wooden boards, bolts and tools are measured in fractions in the construction industry.

How do I calculate occupant load?

The occupant load factor is used to specify the minimum amount of space needed per person, and it varies according to what the space is being used for. For instance, classrooms only require 20 net square feet per occupant, whereas offices require at least 100 gross square feet per occupant, and residences need at least 200 gross. The most recent occupant load factors can be found in Table 1004.1.2 of the 2015 IBC.\n\nIt's important to consider that some occupant load factors are determined in gross square feet per occupant, but others are determined in net square feet. The gross area of a..

What are consecutive prime numbers?

Some examples of prime numbers are 5, 7, 11, 13 and 17. Using these numbers in a sequence such as 11, 13, 17 means they would be consecutive, as there are no prime numbers between any of these three numbers.\nOn the other hand, the sequence 7, 13, 17 would not represent consecutive prime numbers because the prime number 11 can go between the 7 and the 13.

How is the diameter of a basketball hoop?

The distance from the top of the of the goal to the floor is exactly 10 feet for standard play. A professional National Basketball Association or Women's NBA court measures 94 feet long and 50 feet wide. The foul line sits 15 feet from the front of the backboard. High school and junior courts differ greatly in size, but the measurements of the backboards and rims are generally the same for all levels of play. For unprofessional leagues or practice fields, all measurements may vary.

What number is written XV in Roman numerals?

The rules applying to combination of letters prohibit the use of a particular letter more than three successive times within a number. When the value of a letter is the same or larger than the one immediately following it, the numbers are added. In the Roman numeral XV, X is larger than V, so the two are added together for a total of 15. When a letter has a smaller value than that of the letter immediately following it, the smaller value is subtracted from the larger value. In the Roman numeral IV, for instance, the I has a lower value than the V, so the one is subtracted from the five for a t..
