This set of resources includes 2x PPTs which can be delivered over 3 lessons (around 50 slides of engaging and interactive learning) and 1x word file of an exam style case study and question.

Learners are introduced to the world of inventory management and supply chains. We look at ways to match supply to the demand i.e through outsourcing or temporary and part time work. We also look at inventory control charts and factors that make a good reliable supplier.

Many real life examples are given throughout the bundle to help students contextualise. A variety of tasks to consolidate this knowledge through discussions, case studies and more. Exam question, with model answer and marking grid so students can self/peer assess to identify WWW and EBI with their answers.

A kahoot quiz and box plenary to summarise learning.

Colourful, concise and engaging slides! Thank you

Get Started with Apache Cassandra

Interested in getting started with cassandra follow these instructions., step 1: get cassandra using docker.

You’ll need to have Docker Desktop for Mac, Docker Desktop for Windows, or similar software installed on your computer.

Apache Cassandra is also available as a tarball or package download .

STEP 2: START CASSANDRA

A Docker network allows us to access the container’s ports without exposing them on the host.

STEP 3: CREATE FILES

The Cassandra Query Language (CQL) is very similar to SQL but suited for the JOINless structure of Cassandra.

Create a file named data.cql and paste the following CQL script in it. This script will create a keyspace, the layer at which Cassandra replicates its data, a table to hold the data, and insert some data into that table:

STEP 4: LOAD DATA WITH CQLSH

The CQL shell, or cqlsh, is one tool to use in interacting with the database. We’ll use it to load some data into the database using the script you just saved.

Note: The cassandra server itself (the first docker run command you ran) takes a few seconds to start up. The above command will throw an error if the server hasn’t finished its init sequence yet, so give it a few seconds to spin up.

STEP 5: INTERACTIVE CQLSH

Much like an SQL shell, you can also of course use CQLSH to run CQL commands interactively.

This should get you a prompt like so:

STEP 6: READ SOME DATA

Step 7: write some more data, step 8: clean up.

CONGRATULATIONS!

Hey, that wasn’t so hard, was it?

3 4 5 Triangle

Learn about 3 4 5 triangles., 3 4 5 triangle lesson, what is a 3 4 5 triangle.

A 3 4 5 triangle is an SSS right triangle (meaning we know the three side lengths). If we know two of the side lengths and they are congruent with the 3 4 5 ratio, we can easily determine the third side length by using the ratio. The other common SSS special right triangle is the 5 12 13 triangle .

We call it the 3 4 5 "ratio" because the side lengths do not need to be exactly 3, 4, and 5, but rather can be any common factor of these numbers. For example, a right triangle with side lengths of 6, 8, and 10 is considered a 3 4 5 triangle. Its side lengths are a common factor of 2 of the 3 4 5 ratio.

A 3 4 5 triangle is classified as a scalene triangle since all three sides lengths and internal angles are different.

List of 3 4 5 Triangles

The following are some of the most common sets of 3 4 5 triangle side lengths. We do not need to memorize this list as long as we are aware that the ratio can be multiplied by a common factor to produce any of these sets of side lengths.

3 4 5 Triangle Angles

The three internal angles in degrees are 36.87, 53.13, and 90. The three angles in radians are 0.64, 0.93, and 1.57. See the image below for the location of these angles.

How to Construct a 3 4 5 Triangle

We can construct a 3 4 5 triangle by starting with a two lines that meet at a right angle. Make the vertical line about 3/4 as long as the horizontal line. Then, connect the ends of these two lines with a straight line.

The connecting line makes our hypotenuse, which will end up being about 5/4 as long as the horizontal side, and about 5/3 as long as the vertical side. Label the short leg 3, the long leg 4, and the hypotenuse 5.

Equations for Area and Perimeter

The equation for area of a 3 4 5 triangle is given as:

Area = 1 / 2 bh

This becomes area = 1 / 2 (3)(4) = 6 when it is a true 3 4 5 triangle. If the triangle is scaled from the ratio by a common factor, we can multiply 6 by that common factor to get the area.

The equation for perimeter is given as:

Perimeter = a + b + c = 3 + 4 + 5 = 12 for a true 3 4 5 triangle.

If the triangle is scaled from the ratio by a common factor, we can multiply 12 by that common factor to get the perimeter.

Proof of the 3 4 5 Triangle

Let’s take a look at the math that proves the existence of the 3 4 5 ratio. We are going to use the standard side lengths of 3 and 4 to look for the 3rd side length using the Pythagorean theorem.

• Remember that a 2 + b 2 = c 2 .
• 3 2 + 4 2 = 9 + 16 = 25
• 5 2 = 25, so the 3 4 5 right triangle ratio is satisfied.

Let’s prove it again with a different example. We are going to multiply the numbers of the ratio by a common factor of 2.

• 6 2 + 8 2 = 36 + 64 = 100
• 10 2 = 100, so the 3 4 5 right triangle ratio is satisfied.
• This proves the ratio holds true even when scaled by a common factor.

3 4 5 Triangle Example Problem

Which of the following triangles are 3 4 5 right triangles?

• Triangle 1: 8, 8, 25
• Triangle 2: 9, 12, 15
• Triangle 3: 23, 27, 31
• Triangle 4: 12, 16, 20
• Triangle 5: 6, 8, 10
• Triangle 2 is the 3 4 5 ratio multiplied by a common factor of 3.
• Triangle 4 is the 3 4 5 ratio multiplied by a common factor of 4.
• Triangle 5 is the 3 4 5 ratio multiplied by a common factor of 2.
• Therefore, triangles 2, 4, and 5 are 3 4 5 right triangles .
