The <u>correct answer</u> is:

Connect two arcs together with a compass.

Explanation:

When inscribing polygons, most polygons require two arcs to be connected at some point.

For a dodecahedron, we at one point must bisect an angle, which requires connecting two arcs.
For a square, you either bisect angles or draw a perpendicular bisector; both require connecting two arcs.
For an octagon, you bisect quadrants, which requires connecting two arcs.

Doubling the number of sides of an inscribed polygon is done by bisecting the segments of the circle; again, this requires connecting two arcs.

The answer is "Connect two arcs together with a compass".
You can inscribe different regular polygons by creating a circle and connecting two arcs together. There are different procedures and they depends on what kind of regular polygon you will be creating.

Mrs. Nguyen used 1.48 meters of netting to make 4 identical mini hockey goals. How much netting did she use per goal?

snow_tiger [21]

0.37 meters of netting

<h3>Further explanation</h3>

<u>Given:</u>

Mrs. Nguyen used 1.48 meters of netting to make 4 identical mini hockey goals.

<u>Question:</u>

How much netting did she use per goal?

<u>The Process:</u>

We will solve the problem of conversion or in other words the ratio or proportion.

Option A: the conversion

Mrs. Nguyen used 1.48 meters of netting to make 4 identical mini hockey goals.

Then for every 1 goal, she needs 0.37 meters of netting.

Because $\boxed{ \ 1 \ goal \times \frac{1.48 \ meters}{4 \ goals} = 0.37 \ meters \ of \ netting.}$

Option B: the ratio (or proportion)

In the ratio, we process as follows:

$\boxed{ \ 4 \ goals : 1.48 \ meters \ of \ netting \ }$

Both are divided by 4.

$\boxed{ \ 1 \ goals : 0.37 \ meters \ of \ netting \ }$

Thus, she uses 0.37 meters of netting per goal.

Alternative problem

How much netting did she use for 8 goals?

$\boxed{ \ 8 \ goal \times \frac{1.48 \ meters}{4 \ goals} = \ ? \ }$ meters of netting.

We cross out eight and four because they can be divided.

$\boxed{ \ 2 \times 1.48 \ meters = 2.96 \ meters \ of \ netting. \ }$

She uses 2.96 meters of netting to make 8 identical mini hockey goals.
