This document provides steps for creating a formula in Excel to calculate missing angles in triangles and rectangles. It instructs the user to: 1) Set up labeled cells to enter known angles for a triangle or rectangle. 2) For a triangle, use the formula =180-(B3+B4) in cell B5 to calculate the missing angle based on the fact that interior angles of a triangle sum to 180 degrees. 3) For a rectangle, decide on a formula to calculate the missing angle based on the fact that interior angles of a rectangle sum to 360 degrees. 4) Save the Excel sheet as "Missing_Angle_Calculator" and test it by calculating missing angles for sample triangles

Ppt about theory of powers and roots
The document discusses square numbers and square roots. It defines a square number as a number that can be represented as a perfect square array, with each small square having a side length of 1. A square root is the number that, when multiplied by itself, equals the original number. The document provides examples of perfect squares and their square roots, and methods for finding the square root of larger numbers by factoring them into smaller perfect squares.
Measured And Exact Numbers
The document discusses measured numbers and significant figures. It provides examples of measuring lengths using a meter stick and estimating digits.

Proportion
A proportion is an equation that sets two ratios equal to each other. The extremes (first and last terms) of a proportion are equal to the product of the means (middle terms). For example, if a/b = c/d, then a*d = b*c. Proportions can be used to solve scale drawings and models where the scale gives the ratio between actual dimensions and those depicted. Setting up and solving proportions allows finding unknown values when a scale ratio and one set of dimensions is given.
Sig figs.ppt
This document discusses uncertainty in measurement and significant figures. It explains that measurements have uncertainty due to limitations of instruments. Precision refers to the agreement between repeated measurements while accuracy is the agreement with the true value. There are two types of errors - random errors that can be high or low, and systematic errors that are always in the same direction. The document provides rules for determining the number of significant figures in measurements and calculations, including how significant figures are treated in addition, subtraction, multiplication and division.
Square root

Here are the steps to draw an equilateral triangle using the diameters method:
1. Draw a circle of any convenient size.
2. Draw two diameters of the circle that intersect at right angles. These will form the bases of the triangle.
3. With the points where the diameters intersect the circle as centers, and using the radius of the circle as the radius, draw arcs above the diameters.
4. The point where the arcs intersect will be the third vertex of the equilateral triangle.
5. Connect this point to the two base points to complete the equilateral triangle.
The key steps are using the diameters of the circle as the bases, and the fact that arcs drawn with the same

For this Applied Knowledge Assessment, you will use the concepts learned throughout this unit. You will develop your understanding of nets, perimeter, and area. Refer back to individual lessons if you need help.
Nets in the Kitchen
This assessment is worth 75 points. Show all work on this sheet and submit one document for full credit.
Part 1: Nets
Recall (refer to page 12 in your textbook if necessary) that a net is a two-dimensional pattern that you can fold to form a three-dimensional figure. You are to create nets for two different boxes from your house. Some good box examples include: cereal boxes, pasta boxes, cracker boxes, etc.
1. Rummage through your house and locate the two different boxes that you will use for this activity.
2. In the space provided below, describe what your original box looks like in a few sentences. You may also take pictures of your box and insert them into this document; however, this is not mandatory. When describing each three-dimensional figure, be sure to use complete sentences and proper grammar/spelling.
3. Create a net for each box. You may cut the box to help you unfold it into a two-dimensional piece.
4. Sketch your net in the space provided below. You must sketch your net by hand. The size of the net will not be drawn to scale. Draw each net to fit in the provided space. Use a ruler or other straight edge to make neat, straight lines.
Part 2: Perimeter and Area
Part 2 of this assessment will focus on perimeter and area. Choose one of your boxes from Part 1 to complete this activity. You will need a ruler. If you do not have one available, you may visit the following link to print and cut out a ruler:
http://www.vendian.org/mncharity/dir3/paper_rulers/UnstableURL/ruler_foot.pdf
1. Measure the top of your box. Draw a picture of the top of the box. Include your measurements and label the units. You may use inches or centimeters for the units. (Be sure to use the same units for the remainder of Part 2.)
2. What is the perimeter and area of the top of the box? Show all work and include the proper units.
3. Measure the front of your box. Draw a picture of the front of the box. Include your measurements and label the units.
4. What is the perimeter and area of the front of the box? Show all work and include the proper units.
5. Measure the bottom of the box. Draw a picture of the bottom of the box. Include your measurements and label the units.
6. What is the perimeter and area of the bottom of the box? Show all work and include the proper units.
7. Compare the areas of the pieces of the box. Which pieces have the same area? Why?
8. There are some pieces of the box that we did not measure. Use your knowledge of area and your findings from the previous questions to infer which pieces of the box will have the same area (you do not need to calculate the actual areas here). Be sure to list all parts of the box (top, bottom, front, back, side 1, and side 2).

11.8 probabilities of disjoint and overlapping events wiki
The document discusses probabilities of disjoint and overlapping events. Disjoint events have no common outcomes, while overlapping events share at least one outcome. It provides examples of calculating probabilities of disjoint and overlapping events. Complementary events are disjoint and their probabilities must sum to 1, with the probability of an event not occurring equaling 1 minus the probability of it occurring.
11.9 dependent and independent events
The document outlines a lesson plan to teach students the difference between independent and dependent events and how to calculate the probability of each. The lesson will begin with explaining the key concepts, then provide examples to illustrate the difference between independent and dependent events. Students will have opportunities to ask questions and practice calculating probabilities of independent and dependent events.

10.4 area and circumference of a circle
The document defines key terms related to circles:
- A circle is the set of all points in a plane that are an equal distance from the center.
- The radius is the distance from the center to any point on the circle.
- The diameter is the distance across the circle through the center.
- The circumference is the distance around the entire circle.
10.5 surface area of prism and cylinder
To calculate the surface area of prisms and cylinders, you must find the area of the bases and lateral faces/surfaces and add them together. For prisms, the lateral faces are all faces except the bases, and their total area is called the lateral area. Similarly, the curved surfaces of cylinders are called the lateral surfaces, and their total area is the lateral area. Formulas can be used to efficiently calculate the surface areas of prisms and cylinders by incorporating the measurements of their dimensions.

8.7 interest
Interest is the fee charged by a lender to a borrower for the use of borrowed money. The interest rate is usually expressed as an annual percentage of the principal amount that is owed. Interest is calculated on the principal amount over a period of time, such as monthly or annually, and is added to the total amount owed by the borrower.
