<span>Open and closed circles are used to mark the end points of intervals.
If the circle is open, it means the end point is NOT included in the interval,
but if the circle is closed, it means the end point is included.
Consider the interval . In this interval, the low endpoint, the 3,
is not included because you have a 'less than' sign. The high endpoint, the 6,
is included because you have a 'less than or equal' sign. It is the presence
or absence of the 'or equal' part that determines whether the circle is closed
or open.
The interval would be marked on the number line with an open
circle at 3, a closed circle at 6, and a heavy line connecting the two.

<u>Answer:</u>
1130400 km
<u>Step-by-step explanation:</u>
We know the formula for circumference of a circle:
<em>Circumference = 
</em>
So we need the radius of Saturn ring to calculate its circumference.
We are given Saturn's diamter which is 120,000km; and know that Saturn's ring extends for about 120,000 km from the circumference of the Saturn.
Therefore, the radius of Saturn's ring will be 120000 km plus half of the diameter of Saturn:
Radius of Saturn's ring = 120000 + (120000/2) = 180000 km
Circumference of Saturn's rings = 2 x 3.14 x 180000 = 1130400 km

Answer:
One pair of socks would be 1 dollar and 30 cents
Step-by-step explanation:
you divide the price of the socks by how many socks there are to get the answer.
Answer:
The key fact about the enlargement, scale factor > 1
The key fact about the reduction, 0 < scale factor < 1
Step-by-step explanation:
<em>Let us explain what is the dilation?</em>
- A dilation is a transformation that changes the size of a figure.
- It can become larger or smaller, but the shape of the figure does not change.
-
The scale factor measures how much larger or smaller the image will be
- If the scale factor greater than 1, then the image will be larger
- If the scale factor between 0 and 1, then the image will be smaller
Enlargement means the image of a figure after dilation is larger than the original figure
Reduction means the image of a figure after dilation is smaller than the original figure
The key fact about the enlargement is that the scale factor of dilation must be greater than 1 ⇒ scale factor > 1
The key fact about the reduction is that the scale factor of dilation must be between 0 and 1 ⇒ 0 < scale factor < 1
