Answer:

Sum of the interior angles = 1440 degrees.

Step-by-step explanation:

There are a total of 10 interior angles in the decagon. Now for all polygons the sum of all the exterior angles is 360 degrees.  There are 10 exterior angles in the decagon  and, since it is regular, each of them = 360/10 = 36 degrees. Each interior angle therefore  measures 180 - 36 degrees and the sum of the interior angles is this value times ten.

360 / 10 = 36.

180 - 36 = 144.

10 * 144 = 1440 degrees.

Lisa sold $75 worth of play tickets.Adult tickets cost $4 each and children’s ticket cost $4 each.How many children’s tickets co
Helga [31]
Yes, there are many possible answers. An equation that can model your situation is:
4a+4b=75, with a being the amount of adult tickets sold, and b being the amount of children’s tickets sold.
Because both tickets cost 4 dollars, you would multiply the amount of tickets sold, by the price (in dollars) of the ticket.
So, you can find possible answers by substituting the amount of adult tickets sold. Say, 4 adults bought tickets. You could then substitute a for 4. So the equation would look like this.
4(4)+4b=75
16 + 4b = 75
4b = 75 - 16
4b = 59
Divide each side by four
B = 14.75

The reason you got a decimal number is because 75 cannot be divided by 4 evenly. So, in this context, you could say that 15 children bought tickets. One child had an issue, and Lisa gave them a 25% discount. This would explain why there are only 75 dollars worth in tickets. I hope I helped, this is my first question I have ever answered so I’m not entirely sure if this was helpful or not. Hope you figure this out!

Answer:

1. 14

2.400 pieces

Step-by-step explanation:

2. remember 1 meter is 100 centimeters, thus to find how many centimeters are in 24 m multiply 100 by 24. this will get 2400 centimeters

divide 2400/6 and you will get 400
