Chanda can bake and decorate 72 cookies in 2.5 hours. at this rate, how long will it take her to bake and decorate 108 cookies?

a. 3.75 hours

b. 43.2 hours

c. 36 hours

d.14.4 hours

if you can, and you very much if you do!

i would divide 72 and 2.5 and what do you get 28.8 for your rate now divide 28.8 by 108 and you get 3.75 , so you get A

given that triangle abc is transformed two times to get triangle

a"b"c"

first abc is transformed in to a'b'c' as follows:

the coordinates of a are (1,-1) and transformed into a'(-1,1)

similarly b (4,-2) became b'(-4,2) and

c(7,-2) became c'(-7,2)

i.e. (x,y) becomes (-x,-y)

this is nothing but reflection about a point here origin.

thus first transformation is reflection on the origin.

next is exactly shifting 3 units down
