Linear Relationships - Comparing Costs
a) Determine the cost of each plan if you send 500 text messages in one month. Show your working out. Plan A: $79.95 Plan B: $90.2 Plan C: $74.95 I worked this out by looking at the graph where the x axis was 500 (the x axis was amount of texts sent), and then I saw where each line landed on the y axis. b) Your boss asks you to visually display three plans and compare them so you can point out the advantages of each plan to your customer. c) A customer wants to know how to decide which plan will save her the most money. Determine which plan has the lowest cost given the number of text messages a customer is likely to send. For anything less than 400 texts, Plan A is the best (cheapest). For anything more than 400 and less than 800 texts, Plan C is the best (cheapest). For anything more than 800 texts, Plan B is the best (cheapest).
You Should Eat Bugs!
You should eat bugs! I mean, firstly, you already eat them. Next, there are so many more options! In the US, the food standards for canned fruit juices allow 1-2 larvas and 5 fruit-fly eggs. This is the maximum amount of insects that are allowed to be found in foods. So, if you already eat them, why don't you just know that you are eating them, because they are pretty healthy! They have a lot of protein in them. Also, there are so many bugs, humans could never run out! There are around 6 million different species of insects, and 80% of all animals walk on 6 legs (insects). This means that there are about 200 to 2,00kg of insects for each person on earth. Compared to how much protein you are getting now, the insects will provide you with much more. There are already 1,000 species that are being eaten around the world, and there are so many different ways you can prepare them. Also, we will have to. I mean, without insects we wouldn't be alive. The types of mammals and other anim...
Finding Heights of Objects Using Similarity
This activity was about using proportions to find measurements. It was also using prior knowledge (such as my height), to find the height of the pole which was unknown. We took a picture, and then put it up on our laptop. Then, we measured how big we were on the screen (I was 1.5 cm, and the pole was 6.3 cm). Since we already knew that I was 57 inches, we had to find the scale factor. To find it, we divided 6.3 by 1.5, and the answer was 4.2, the scale factor. Then we multiplied my real height by the scale factor to find the height of the pillar in real life. 57 x 4.2 is 239.4. The height of the pole is 239.4 inches.
