The Dockland office building in Hamburg, Germany is an example of a parallelogram that is not also a square, rhombus or rectangle. It was completed around 2006 by BRT Architekten for Robert Vogel GmbH & Co. The building is located at the end of the Edgar-Engelhard-Kai, between the Fischereihafen and the northern Elbe. The building resembles a ship with a cantilevering "prow" over the dock, and it is considered a gateway to the city.

Solve the inequalityFor example with the inequality 3x + 6 >= 15, isolate x as its own term. Subtract 6 from both sides, leaving 3x >= 9, then divide by 3 on both sides. The value of x should be greater than or equal to 3.Draw the number lineSet a value for zero, and mark the increments as necessary. Mark arrows on either end of the line to denote that the line is understood to extend further. Mark the spot on the line that corresponds to the value of x you just found. In this case, it's 3, so make a mark at that point. If the inequality includes the value, shade the number. If it's ..

Calculate powers of 10 using a shortcut: add the same number of zeros as the exponent to the number 1. For example, to calculate 10 to the 8th power quickly, place 8 zeros after the 1. To determine where the commas go after calculating the power of 10, start at the end of the number with the last zero. Count back three digits at a time and insert a comma. Continue this until the beginning of the number is reached.
Why does "b" stand for "y-intercept"?

The form y = mx + b of a linear equation is called slope-intercept form because the coefficients m and b represent the slope and y intercept respectively. For any equation in terms of x and y, one can calculate the y-intercept by substituting zero for the value of x. In the case of a linear equation written in slope-intercept form, substituting zero for x results in y = m(0) + b, which simplifies to y = b. Therefore, b stands for the y-intercept.

Several ways exist to prove triangles congruent. Aside from the SSS (or side-side-side) method, there are the SAS (side-angle-side), ASA (angle-side-angle), AAS (angle-angle-side) and HL (hypotenuse-leg) postulates. If triangles are congruent by any one of these, they are congruent. Congruent triangles have the same shape and size, though it is possible for one to be a mirror image of the other or rotated in some other way.
Are there online resources to teach children about listing fractions from least to greatest?

Math is Fun teaches students how to compare two fractions to find the greater of the two. A typical example of ordering fractions is ordering 1/6, 4/9 and 3/12 from least to greatest. The first step is to express these fractions with a common denominator as 6/36, 16/36 and 9/36. The next step is to look at the numerators and list them form lowest to greatest, which is 6/36

The term "congruent" in geometry indicates that two objects have the same dimensions and shape. Although congruence statements are often used to compare triangles, they are also used for lines, circles and other polygons.For example, a congruence between two triangles, ABC and DEF, means that the three sides and the three angles of both triangles are congruent.Side AB is congruent to side DE.Side BC is congruent to side EF.Side CA is congruent to side FD.Angle A is congruent to angle D.Angle B is congruent to angle E.Angle C is congruent to angle F.By knowing some of these six congruences, it ..

When a mass is input into the Schwarzchild radius calculator, it can be determined that the mass will collapse into a black hole when the mass reaches the radius given. For example, if the mass of earth was put into the Schwarzchild calculator, the calculator would then return a number that would be the radius the earth would need to be in order to turn into a black hole. This calculator is the best way for astrophysicists to determine when a planet or a mass of anything will turn into a black hole. When they are able to know the approximate radius of the black hole inevitability, they will be..
What is the weight of 1 gallon of water?

Water's weight varies with how densely its molecules pack together. At high temperatures, the molecules are farther apart. Impurities, including minerals, gases, bacteria or dissolved chemicals, affect the weight of water from common sources such as the tap or a pond. Natural seawater, with a roughly 3.5 percent salt concentration, weighs about 8.56 pounds per gallon. Ice, the solid form of water, is 9 to 10 percent less dense than liquid water, which is why it floats.

The four most common signs (addition, subtraction, multiplication and division) are used to perform basic mathematical equations. German mathematicians invented the addition and subtraction signs at the end of the 15th century. The multiplication and division signs came later. In 1631, W. Oughtred introduced the multiplication sign, and in 1684, G. Leibniz invented the division sign.\nThe pi symbol came about in 1706 when W. Jones created it. Generally, pi is approximated as 3.14 to make calculations easy, but the actual number contains more decimal places. There is a pi button on most scienti..
