Ples help smart redstoners A plane flew 3,100 kilometers at a speed of 775 kilometers per hour. How many hours was the flight?

Speed = StartFraction distance Over time EndFraction

The flight was

O 4

O 13

O 25

O 44

hours long.

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

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
