SLR is the abbreviation of what in the field of photography? - Single Lens Reflex camera Which company is the largest producer of computer software for personal computers? - Microsoft What does the abbreviation GUI stand for? - Graphical User Interface Which element was discovered by the French chemists Marie Curie and Pierre Curie? Radium Geometry Word Problems Involving Perimeter Example 1: A triangle has a perimeter of 50. If 2 of its sides are equal and the third side is 5 more than the equal sides, what is the length of the third side? Solution: Step 1: Assign variables: Let x = length of the equal side Sketch the figure Step 2: Write out the formula for perimeter of triangle. P = sum of the three sides Step 3: Plug in the values from the question and from the sketch. 50 = x + x + x+ 5 Combine like terms 50 = 3x + 5 Isolate variable x 3x = 50 5 3x = 45 x =15 Be careful! The question requires the length of the third side. The length of third side = 15 + 5 =20 Answer: The length of third side is 20 Geometry Word Problems Involving Area Example 1: A rectangle is 4 times as long as it is wide. If the length is increased by 4 inches and the width is decreased by 1 inch, the area will be 60 square inches. What were the dimensions of the original rectangle? Solution: Step 1: Assign variables: Let x = original width of rectangle Sketch the figure Step 2: Write out the formula for area of rectangle. A = lw Step 3: Plug in the values from the question and from the sketch. 60 = (4x + 4)(x 1) Use distributive property to remove brackets

60 = 4x2 4x + 4x 4 Put in Quadratic Form 4x2 4 60 = 0 4x2 64 = 0 This quadratic can be rewritten as a difference of two squares (2x)2 (8)2 = 0 Factorize difference of two squares (2x)2 (8)2 = 0 (2x 8)(2x + 8) = 0 We get two values for x. Since x is a dimension, it would be positive. So, we take x = 4 The question requires the dimensions of the original rectangle. The width of the original rectangle is 4. The length is 4 times the width = 4 4 = 16 Answer: The dimensions of the original rectangle are 4 and 16. Geometry Word Problems involving Angles Example 1: In a quadrilateral two angles are equal. The third angle is equal to the sum of the two equal angles. The fourth angle is 60 less than twice the sum of the other three angles. Find the measures of the angles in the quadrilateral. Solution: Step 1: Assign variables: Let x = size of one of the two equal angles Sketch the figure Step 2: Write down the sum of angles in quadrilateral. The sum of angles in a quadrilateral is 360 Step 3: Plug in the values from the question and from the sketch. 360 = x + x + (x + x) + 2(x + x + x + x) 60 Combine like terms 360 = 4x + 2(4x) 60 360 = 4x + 8x 60 360 = 12x 60 Isolate variable x 12x = 420 x = 35 The question requires the values of all the angles. Substituting x for 35, you will get: 35, 35, 70, 220 Answer: The values of the angles are 35, 35, 70 and 220 Protons, Neutrons and Electrons Atoms are incredibly small and are mostly empty space. Each atom consists of a nucleus and a cloud of particles called electrons that fly around the nucleus. The nucleus is a cluster of two kinds of particles, protons and neutrons.

All the particles in an atom are very light. Their mass is measured in atomic mass units. Protons and electrons have an electric charge, whereas neutrons do not have an electric charge. Particle in atom Mass Charge Proton 1 unit positive charge (1 +) Neutron 1 unit none Electron almost nothing negative charge (1 -) Atomic Number The number of protons in an atom can be used to identify the atom. Every other atom has a different number of protons. For example, since only a sodium atom has 11 protons then any atom with 11 protons would be a sodium atom. The number of protons in an atom is called its atomic number or proton number. For example, the atomic number of sodium is 11. Number of Electrons Every neutral atom has an equal number of protons and electrons. This means that the total charge on the protons cancels out the total charge on the electrons and the atom has no overall charge. For example, the sodium atom has 11 protons and 11 electrons and there is no overall charge. Nucleon Number Protons and neutrons, also called nucleons, are located in the nucleus of the atom. The total number of protons and neutrons in an atom is called its nucleon number. For example, the sodium atom has 11 protons and 12 neutrons. The nucleon number for the sodium atom is 11 + 12 = 23. Isotopes Isotopes are atoms of the same element, with different numbers of neutrons. For example, all carbon atoms have 6 protons but some carbon atoms have more neutrons than others. Carbon-12 has 6 protons, 6 electrons and 6 neutrons. Carbon-13 has 6 protons, 6 electrons and 7 neutrons. Carbon-14 has 6 protons, 6 electrons and 8 neutrons. Carbon-12, Carbon-13 and Carbon-14 are called isotopes of carbon.

Science A diamond will not dissolve in acid. The only thing that can destroy it is intense heat. A lump of pure gold the size of a matchbox can be flattened into a sheet the size of a tennis court. Absolutely pure gold is so soft that it can be molded with the hands. An ounce of gold can be stretched into a wire 50 miles long. Colored diamonds are caused by impurities such as nitrogen (yellow), boron (blue). With red diamonds being due to deformities in the structure of the stone, and green ones being the result of irradiation. Diamond is the hardest naturally occurring substance, and is also one of the most valuable natural substances. Diamonds are crystals formed almost entirely of carbon. Because of its hardness, the diamond is the most enduring of all gemstones. They are among the most costly jewels in the world, partly because they are rare, Only four important diamond fields have been found - in Africa, South America, India, and the Soviet Union. In 1957, the Shipping port Atomic Power Station in Pennsylvania, the first nuclear facility to generate electricity in the United States, went on line. (It was taken out of service in 1982.) In 1982, in the first operation of its kind, doctors at the University of Utah Medical Center implanted a permanent artificial heart in the chest of retired dentist Dr. Barney Clark, who lived 112 days with the device. Mercury is the only metal that is liquid at room temperature. Mineral deposits in caves: The ones growing upward are stalagmites, the ones growing downward are stalactites. Natural gas has no odor. The smell is added artificially so that leaks can be detected. Prussic acid, in a crystalline powder called Zyklon B, was used to kill in Germany's gas chambers. The gas would paralyze the victim's lungs, causing them to suffocate. Sea water, loaded with mineral salts, weighs about a pound and a half more per cubic foot than fresh water at the same temperature. Ten per cent of the salt mined in the world each year is used to de-ice the roads in America. The air we breathe is 78% nitrogen, 21.5% oxygen, .5% argon and other gases. The Chinese were using aluminum to make things as early as 300 AD Western civilization didn't rediscover aluminum until 1827. The Cullinan Diamond is the largest gem-quality diamond ever discovered. Found in 1905, the original 3,100 carats were cut to make jewels for the British Crown Jewels and the British Royal family's collection. The largest gold nugget ever found weighed 172 lbs., 13 oz. The largest hailstone ever recorded was 17.5 inches in diameter - bigger than a basketball. The most abundant metal in the
