The Kwon family has a rainwater catchment system they use to water their garden. The storage tank is 80 inches deep. After 3 hours of rain, the depth of water in the tank is 37
inches. After 5 hours, the depth is 60 inches. If the rain continues to fall at the same rate,
how many hours will it take to fill the tank? Round your answer to the nearest tenth.
N
hours

about 7 hours

Step-by-step explanation:

i smart

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
