A school principal is mapping out some new features for a triangular playground. He sketches the playground on grid paper. The coordinates of the vertices of the playground are (1, 10), (−5, 2), and (7, 2).   The principal wants to plant a tree at the circumcenter of the playground. What are the coordinates of the tree?   ( __,__ )

the radius is 2 times the diameter.

step-by-step explanation:

the distance between the school and her home is 3.6km.

12 mins = 0.2 hours = 1/5 hour

54 ÷ 3 = 18km per hour

1/5 of 18 = 3.6km per 12 mins

hello there,

to convert kg to pounds and ounces you set up

turn the kg into

8.3/x = 1/2.2

x = 18.26

now convert the pounds into

18.26/x = 1/16

x = 292.16

now that is the answer in ounces.

answer: 18.26 lb; 292.16 oz

hope i
