Answer:

You will need 20 sides to complete the loop.

Step-by-step explanation:

The question isn't quite clear given how small the corner is, but I assume that we are looking to complete the circle if the pentagon and square are repeated in a loop

We can also see - assuming that those are proper equal-sided polygons, that PQ is the same length as PV

With that in mind, We can solve this by noting that the angle of a corner in a square is 90 degrees, and in a pentagon it's 108 degrees.

108 - 90 is equal to 18. This means that PQ is at eighteen degrees to YP. Also, QM, (which will be equivalent to the next VP is eighteen degrees to PQ.

This means that each polygon is rotated 18 degrees relative to it's neighbour.

With all that we can say that the total polygons we need to form a circle is 360/18 = 20, So you will need 20 polygons, or ten squares and ten pentagons to complete the loop.

Zoe had 3 1 /8 feet of orange ribbon. She used some ribbon to make a bow for a gift now she has 1 3 /8 feet of orange ribbon lef
Nastasia [14]

Answer:

Orange ribbon Zoe use is  1\frac{3}{4} \ feet.

Step-by-step explanation:

Given:

Zoe had 3 1 /8 feet of orange ribbon. She used some ribbon to make a bow for a gift now she has 1 3 /8 feet of orange ribbon left.

Now, to find the orange ribbon Zoe use.

Let the orange ribbon Zoe use be x.

Total orange ribbon Zoe had = 3\frac{1}{8} = \frac{25}{8} \ feet.

Ribbon Zoe had left = 1\frac{3}{8} =\frac{11}{8} \ feet.

Now, to get the orange ribbon Zoe use:

\frac{25}{8} -x=\frac{11}{8}

<em>Subtracting both sides by </em>\frac{11}{8}<em> we get:</em>

\frac{25}{8} -x-\frac{11}{8} =0

<em>Adding both sides by </em>x<em> we get:</em>

\frac{25}{8} -\frac{11}{8} =x

\frac{25-11}{8} =x

\frac{14}{8}=x

x=\frac{14}{8}

x=\frac{7}{4}

x=1\frac{3}{4}\ feet.

Therefore, orange ribbon Zoe use is 1\frac{3}{4} \ feet.

stiks02 [169]

Answer:

Check Explanation

Step-by-step explanation:

English Translation

In a report it is said that the predicted minimum temperature is -24 ° C and the maximum is -20 ° C. If the minimum temperature represents colder than the maximum temperature, should it not appear on the reverse? Explain your answer.

Solution

No, it shouldn't appear on the reverse. This is because, just as negative numbers work, they decrease, the further we move away from 0.

Celsius temperature scales are calibrated with respect to the freezing point of water. The freezing point of water serves as the reference point and is called the 0°C.

Temperatures higher than the freezing point of water taken on positive values and temperatures lower, take on negative values. The lower the temperature, the bigger the absolute value of the negative value is.

For example, just like In the question provided, -24°C represents a temperature that is 24° lower than the freezing point of water while -20°C represents a temperature that is 20° lower than the freezing point of water. It is evident that -24°C really is a lower temperature than -20°C.

Hope this Helps!!!
