Question

A party company sells decorations for weddings, birthday parties, and other celebrations. A local high school is having their annual homecoming dance. In order to save money, the homecoming committee made stars congruent to those sold by the party company. One of these stars is shown below.
If each side of the star sold by the party company is 4.5 inches, what is the perimeter, in inches, of each star made by the homecoming committee? Type the numeric answer only in the box below.

Answer 1

I ALSO NEED HELP ON THIS QUESTION PLS

Answer 2

"One of these stars is shown below." Where is the picture? haha.

From the fact that each side is 4.5 I'll just assume it is an equilateral triangle. If that is the case, perimeter = the summation of the lengths of each side.
4.5+4.5+4.5 = 13.5 inches

THANKS SOOOOOOOOOOOOOOO MUCH

Answer 4

A view of Anytown, USA is shown on the grid below with Rock Park represented by quadrilateral RSTU. Due to overcrowding, another park will be built similar to Rock Park. Vertices A and D are plotted on the grid to represent two corners of new Sandstone Park.

Map of Anytown; the line y equals 7 is Main Road; the line y equals 3 is Rose Lane; the line y equals negative 5 is Crystal Avenue; the line x equals negative 4 is Brick Street; the diagonal line increasing from left to right is Dogwood Drive; the diagonal line decreasing from left to right is Gem Lane; Rock Park forms quadrilateral with ordered pairs R at 3, negative 1, S at 7, negative 1; T at 5, negative 3, U at 1, negative 3, A is at negative 4, 5 and B is at negative 4, 3, A is at 8, 4, D is at 7, 3

What could be the ordered pairs representing vertices B and C of quadrilateral ABCD so that Sandstone Park is similar to Rock Park?

B(6, 6), C(5, 5)

B(9, 3), C(8, 2)

B(10, 4), C(9, 3)

B(5, 4), C(5, 3)

Answer 5

Can you check to see if you copied all answer choices correctly? My answer is coming out very similar to one of the choices.

Answer 6

My answer is B (6,4), C (5,3).

Answer 7

Also, @ Puzzhang: If you are finding the perimeter of the star, wouldn't the answer be 45? Because a star has 10 sides, each of which is 4.5 inches. Unless I misunderstood the question...?
