What is the perimeter of a regular heptagon if one side measures 3 inches
svetlana [45]
What's a regular heptagon?  "Hept-" means seven, so a "heptagon" is a seven-sided shape.  A "regular" figure's sides are all the same length.  So, each of the 7 sides are the same length.

Remember, perimeter is the sum of the lengths of all the sides in a polygon.  We know one side measures three inches, so each of the others must also measure 3 inches.  3+3+3+3+3+3+3=3*7=21 inches.

Answer: 21 inches

strojnjashka [21]

Answer:

150 people

Step-by-step explanation:

Lets call the total amount of people at the talent show x. Since 3/6=1/2, we know that half the people are girls, 1/3 are boys. If we added 1/2 and 1/3 we get 5/6, 1-5/6=1/6, so now we know that 1/6 of the people are adults. Because it says "If there were 50 more girls than adults" so from that we can see that 1/2x =1/6x+50. If we were to simplify the equation, we 1/3x=50, so x=150
