Answer:
Step-by-step explanation:
Perimeter of equilateral triangle = 36 inches
Formula of perimeter of equilateral triangle =
⇒
⇒
⇒
Thus each side of equilateral triangle is 12 inches
Formula of area of equilateral triangle =
Where a is the side .
So, area of the given equilateral triangle =
=
Since hexagon can be divided into six small equilateral triangle .
So, area of each small equilateral triangle =
=
So, The area of small equilateral triangle :
Where a is the side of hexagon .
Hence the length of a side of the regular hexagon is
Answer:45.5% decrease????

Answer:
Number of premium tickets sold = 638
Number of regular tickets sold = 552
Step-by-step explanation:
Let number of premium tickets sold be p and number of regular tickets be r.
Total number of seats = 1200
Ticket sales with 10 seats left on, that is
p + r = 1190 ----------------eqn 1
Cost of premium ticket = 30 $
Cost of regular ticket = 20 $
Money collected = 30180 $
Total money collected = 30 p + 20 r = 30180
3p + 2 r = 3018 ----------------eqn 2
eqn 1 x 2
2p + 2r = 2380 --------------------eqn 3
eqn 2 - eqn 3
p = 3018 - 2380 = 638
Substituting in eqn 1
638 + r = 1190
r = 552
Number of premium tickets sold = 638
Number of regular tickets sold = 552
Answer:Hence, Troy spend 9.09 in U.S. dollars.
Step-by-step explanation:
Since the foreign exchange rate between the U.S. dollar and the Swiss franc is 1:2.2.
It means,
1 U.S. dollar = 2.2 Swiss Franc
Now, According to question, Troy spent 20 Swiss francs to stay one night in a youth hostel.
So, 1 Swis Franc =
20 Swiss Franc =
Hence, Troy spend 9.09 in U.S. dollars.
A triangle is 180°. So you can do:
3.2n + 6.4n + 2.4n = 180 Simplify
12n = 180
n = 15 Now that you know the value of n, you can plug it into each individual angle/equation
∠X = 3.2n plug in 15 for n
∠X = 3.2(15)
∠X = 48°
∠Y = 6.4(15)
∠Y = 96°
∠Z = 2.4(15)
∠Z = 36°
