Find the perimeter of pentagon STUVW WITH VERTICES S(0,0) T(3,-2) U(2,-5) V(-2,-5) W(-3,-2)
andrew11 [14]
Use the distance formula.

\sqrt{( x_{2} - x_{1} )^2 + (y_{2} - y_{1})^2}

 
Points S and W.
\sqrt{(3)^2 + (2)^2}

\sqrt{9+4}

\sqrt{13}

~3.6

Points S and T
\sqrt{(3 - 0)^2 + (-2 - 0)^2}

\sqrt{(3)^2 + (-2)^2}

\sqrt{9+4}

\sqrt{13}

~3.6

Points T and U
\sqrt{(3 - 2)^2 + (-2 + 5)^2}

\sqrt{(1)^2 + (3)^2}

\sqrt{1+9}

\sqrt{10}

~3.1

Points U and V
\sqrt{(2+2)^2 + (-5 + 5)^2}

\sqrt{(4)^2 + (0)^2}

\sqrt{16}

~4

Points V and W
\sqrt{(-2+3)^2 + (-5 + 2)^2}

\sqrt{(1)^2 + (-3)^2}

\sqrt{2+9}

\sqrt{11}

~3.3

Add all these together.

Helen [10]

Answer:

4 1/6 ft

Since each of the 18 students gets an equal length of ribbon, we need to divide the 75 ft of ribbon into 18 equal parts.

75/18= 4 1/6

Each student gets 4 1/6 ft of ribbon

Please help please please please!!!!!
Nana76 [90]

Step-by-step explanation:

mean of cheese = 99+8+10/3 = 117/3 = 39

mean of butter = 41+16+0/3 = 57/3 = 19

mean of non fat dairy milk = 255+8+15/3 = 278/3 = 92.6~93

median of cheese 8, 10, 99 median is 10

median of butter 0, 16, 41 median is 16

nonfat dairy milk 8, 15, 255 median is 15

range of cheese 99-10 = 88

range of butter 41-16 = 25

range of nonfat dairy milk = 255-8 = 247
