Knowing that the tiles are regular polygons, we can deduce that each angle of the tile B is 60. Drawing a circle where a vertex of tile B is the center, we can also deduce that the major angle created by the sides of tile B is 300 because all central angles in a circle add up to 360. Since all A tiles are congruent (they are regular and share the same side), we know that their interior angles are also congruent. Since we know their interior angles add up to 300 (because 2 of their interior angles + 60 = 360), we can divide 300 by 2 to calculate each interior angle, which is 150. By subtracting 150 from 180, we get 30 which is the measure of each EXTERIOR angle of tile A. From basic geometry knowledge, we know that the sum of all exterior angles is 360. Using this, we can divide 360 by 30 to get 10 which is the number of sides of tile A.

Final Answer: Tile A has 10 sides, or in other words is decagon.

Latoya drives 8 miles to work in 13 minutes. What is her average rate, in miles per hour, when rounded to the nearest wholes num

Mama L [17]

Answer:

37 miles per hour

Step-by-step explanation:

To find the average rate (average speed) of Latoya in miles per hour, you would divide the distance traveled (in miles) by the time taken to travel (in hours).

So we know that Latoya traveled 8 miles in 13 minutes. We cannot divide 8 by 13, because 13 is in minutes, not hours. We must convert 13 minutes to hours before dividing.

There are 60 minutes in one hour, so to covert minutes into hours, we would divide the minutes (13) by 60. Doing this would give you 13/60. You cannot simplify the fraction 13/60, because 13 is a prime number. It would be best to just leave it as it is for now. So Latoya traveled for 13/60 hours.

Now, to find her average rate in miles per hour, you divide the distance traveled in miles (8 miles) by the time it took to travel in hours (13/60):

8 ÷ 13/60

Remember, a ÷ b/c = a × c/b. Using this:

8 ÷ 13/60 = 8 × 60/13 = 480/13 ≈ 37 rounded to the nearest whole number.

Latoya had an average rate of about 37 miles per hour.

I hope this helps. :)

Which of the following is most likely the next step in the series?

kupik [55]

The circles in the figures form a series

The next step in the series is (B)

<h3>How to determine the next step?</h3>

From the figure, we have the following highlights

The first circle has 2 segments
The second circle has 4 segments
The third circle has 5 segments

Using the above pattern, the next circle must have 6 segments

Hence, the next step in the series is (B)
