A long paper strip with a width of 5 cm is folded, as shown in the picture. Find the smallest possible area of the gray triangle

Stolb23 [73]

By using some logic and the formula of the triangle's area, we will find that the smallest possible area is 12.5 cm²

How to start thinking about the problem.

First of all, for the configuration of this paper strip, we can see that the base of the triangle will <u>always be equal of the width of the paper</u>. Thus, the smallest area will be only dependent of the height of the triangle.

Now, we need to analyze the picture to figure out how we can get the smallest height possible for that triangle.

What is the smallest height possible.

Doing this, we shall see that the smallest height possible is actually when the height equals the width itself, as it's shown in the attached image.

How to calculate the smallest area possible.

Thus, to calculate the smallest area, we just have to use the formula of the area of the triangle, which is $\frac{b\times h}{2}$ <em>, where </em><u><em>b is the base</em></u><em> and </em><u><em>h is the height</em></u><em>.</em>

As we previously found, for this question, the

<em>base = height = width of the paper = 5cm</em>

Now, we just have to calculate it with the formula

$Area = \frac{base \times height}{2} \\\\
\\
Area = \frac{5 \times 5}{2} \\
\\
Area = \frac{25}{2}\\
 \\
Area = 12.5 cm^{2}$

If 450 birds have to fit into 18 enclosures, & there are 3 enclosures in each section of the zoo, how many birds are in each

ANEK [815]

<h3>Answer:</h3>

There are 75 birds in each section

<h3>Step-by-step explanation:</h3>

First, lets see how many in each enclosure so we have an amount to multiply by 3

450/18 = 25 birds per enclosure.

Now lets see how many birds would be in 3 enclosures i.e. a section

25 * 3 = 75

In 2000, the median household income was $41,990. In 2010, it was $49,445. (Source: www.census.gov.)

The average rate of change in the median household income over this time period is $745.5

<h3>What is the average rate of change in the median household income over this time period?</h3>

The given parameters are:

2000, the median household income was $41,990.

2010, it was $49,445.

The average rate of change in the median household income over this time period is calculated as:

Average rate of change = (Difference in Income)/(Difference in years)

So, we have:

Average rate of change = (41990 - 49445)/(2000-2010)

Evaluate

Average rate of change = 745.5

Hence, the average rate of change in the median household income over this time period is $745.5
