Use a strategy to solve this problem. (note: i seriously need and this is due on ) ian is given some red licorice that is wrapped in a coil. upon flattening the licorice, ian discovers that the total length is 60 cm. he then cuts the licorice into two pieces so that the ratio of the lengths of the two pieces is 7: 3. each piece is then bent to form a square. what is the total area of the two squares?

You may feel somewhat overwhelmed right now, because this question is giving the reader lots of information and tasks in a short paragraph. Let's break it down into pieces.

1. First, let's find the ratio of the lengths.

Since the ratio is 7 to 3, we can find the length of each licorice piece by setting its proportion over 10, since that is the sum of the ratio. Thus, one licorice piece has a length of 60 * 7/10 = 42 cm and the other has a length of 60 * 3/10 = 18 cm.

2. Now, let's create our squares.

Each piece is bent to form a square. In other words, the pieces is split into 4 equal sides. Thus, we can divide our lengths by 4. The first piece of licorice made into a square has side lengths of 42/4 = 10.5 cm. The second piece of licorice has side lengths of 18/4 = 4.5 cm.

3. Finding the area of our squares.

Now, all we need to do is find the sum of the areas of the squares. The first square has an area of 10.5^2 = 110.25

cm^2 and the second square has an area of 4.5^2 = 20.25

cm^2. Thus, our answer is 130.5 cm^2.

Answer from: Quest

linearly: 8560 bacteria

exponentially: approximately 75233 bacteria

step-by-step explanation:

assuming it is not exponential (we would have some really complicated logarithms), let's say it is linear. then, after 5 hours, it increased by 1200 bacteria, so every hour it increases by 240 bacteria. this means that after 19 hours, we get 19 * 240 + 4000 bacteria or 3800 + 760 + 4000 = 7800 + 760 = 8560 bacteria.

because it says round your answer, i will do this exponentially (with a calculator, of course). first, we need to find how much it multiplies by every hour, by taking the 5th root of 52/40 or 13/10. this is approximately 0.167. we still need to add 1 to this, because we are multiplying by that number, not adding that amount of the number. now, we just calculate 4000 * (1.167)^19. use a calculator to get approximately 75232.6, or 75233.
