Thank you for your time. Your Friend, Kaylee Kaylle- ve included a great little packet developed in Massachusetts. It has all of the formulas, as well as some other handy goodies for math. To figure out the formulas for parallelograms you need to combine the formulas for a rectangle and triangles. Calculate the rectangle first, then calculate the triangle and times it by 2. Then add the calculation for the rectangle and the triangles together for your answer. Good luck on your math.

25. Math Formulas Part, over Base times Rate; also called Result, over Base times Rate; also called the “Pie Formula” or the “T Formula” (It s all the same thing), http://yourdailyquiz.com/MathFormulas2.htm

Math Formulas Continued Back to page 1 Part, over Base times Rate ; also called Result, over Base times Rate; also called the “Pie Formula” or the “T Formula” (It’s all the same thing), can be used in a variety of circumstances. If you know any two of the three pieces in the formula, you can figure out the one you’re missing. For example, in Commission problems (shown at the right), the Sale Price times the Commission Rate would give you the Commission (the actual dollar amount paid by the seller. The Commission divided by the Commission Rate would give you the Sale Price, and the Commission divided by the Sale Price would give you the rate in decimals (you then need to move the decimal point two places to the right to convert it to a percentage). For Commission problems, the formula would be: Commission Sale Price X Commission Rate To figure the share received by a salesperson or by another broker use: Salesperson’s or Other Broker’s Share Total Commission X Percentage To figure the amount received by the seller after paying the commission use: Seller’s Net Sale Price X (100% – Commission Rate) For Tax problems , the formula would be: Annual Tax Assessed Value X Tax Rate Remember the rate will be expressed in Mills (1 Mill = .001, 50 mills would be .050, and so on).

27. Computing Planetary Positions A detailed online tutorial on how to compute planetary locations using math formulas. http://stjarnhimlen.se/comp/ppcomp.html

How to compute planetary positions By Paul Schlyter, Stockholm, Sweden email: pausch@stjarnhimlen.se or WWW: http://stjarnhimlen.se/ Break out of a frame 0. Foreword 1. Introduction ... Tutorial with numerical test cases 0. Foreword Below is a description of how to compute the positions for the Sun and Moon and the major planets, as well as for comets and minor planets, from a set of orbital elements. The algorithms have been simplified as much as possible while still keeping a fairly good accuracy. The accuracy of the computed positions is a fraction of an arc minute for the Sun and the inner planets, about one arc minute for the outer planets, and 1-2 arc minutes for the Moon. If we limit our accuracy demands to this level, one can simplify further by e.g. ignoring the difference between mean, true and apparent positions. The positions computed below are for the 'equinox of the day', which is suitable for computing rise/set times, but not for plotting the position on a star map drawn for a fixed epoch. In the latter case, correction for precession must be applied, which is most simply performed as a rotation along the ecliptic. These algortihms were developed by myself back in 1979, based on a preprint from T. van Flandern's and K. Pulkkinen's paper "Low precision formulae for planetary positions", published in the Astrophysical Journal Supplement Series, 1980. It's basically a simplification of these algorithms, while keeping a reasonable accuracy. They were first implemented on a HP-41C programmable pocket calculator, in 1979, and ran in less than 2 KBytes of RAM! Nowadays considerable more accurate algorithms are available of course, as well as more powerful computers. Nevertheless I've retained these algorithms as what I believe is the simplest way to compute solar/lunar positions with an accuracy of 1-2 arc minutes.

MATH HOME SITEMAP BASIC MATH CONCEPTS FUN WITH MATH ... Math Tutor Math Formulas Remembering and applying math formulas There are many types of math, including algebra, business math, calculus, general math, geometry, and trigonometry, to name a few. Math formulas are the foundation for all of these math subjects; therefore, it is critical to understand math formulas and their applications to learn each subject successfully. Different types of math formulas are used in different grades of learning. When your child is young, he or she should be taught general math and it is critical that they remember and apply basic math formulas such as addition, subtraction, multiplication, and division. Play games with your child to help reinforce these math formulas. Problems like adding two apples to three or removing two apples from four will help them realize how math formulas work and how to apply them. This will prepare your child for more advanced formulas when they are introduced to them in higher grades. As your child progresses in school, algebra and geometry are some of the math subjects that are taught. Algebra requires knowing how to use different operators, understanding the meaning of the equals sign, the significance of the number zero, and other advanced mathematical concepts. Geometry uses math formulas to analyze characteristics and properties of two- and three-dimensional geometric shapes- the volume of a container, the perimeter of an object, etc. Learning algebra and geometry is important because these subjects are applied in everyday life and are utilized in the workforce.
