A polygon that has both reflectional and rotational symmetry includes:
- B. Square
- C. Triangle
- E. Equilateral Triangle.
<h3>What is a polygon?</h3>
A polygon is a closed curve made up of a set of line segments (sides) connected in such a way that no two segments cross.
Examples of polygons are triangles (three sides), quadrilaterals (four sides), and pentagons (five sides).
Triangle, square, and other quadrilaterals have both line symmetry and rotational symmetry.
Thus, a polygon that has both reflectional and rotational symmetry includes Options B, C, and E.

Answer:
$43 million
Step-by-step explanation:
<h3>Step 1. Turn the sentence into an equation (total = T)</h3>
15.4 million = 0.36 (T)
<h3>Step 2. Solve for T </h3>
15,400,000 / 0.36 = T
42,777,777.78 = T
$42.8 million ≈ $43 million (rounded)
The final answer rounded to the nearest million is $43 million. This makes sense since $15.4 was only 36% of this total. Checking our math, 36% of $43 million is $15.4 million!
Hope this helps :)
For this case we have the following number:
4,288
round to the nearest hundredth means that we must rewrite the number using only 2 decimal places.
Therefore, we must rewrite the number as follows:
4.29
We observed that:
1) the third decimal disappears
2) the second decimal is rounded to the next number since the third decimal is greater than five.
Answer:
4.29
I’m working on the same thing in school! For number 2, what i would do is start by setting up the scatter plot by using the X and Y table and create origins to place on the graph. ( ex. (1,30) for your first one ). Also, remember to write in the laps completed and calories burned. Next, estimate a line that meets as many points as possible. ( I would use the completed scatter plot in number 3 for an example for how to draw the line ). And that’s all I can help you with :( I forgot how to do the equation part because I just started with this on Monday. Hope this helps!
