Ahome has a living room that is 14 ft. wide, 22 ft. long, and a height of 9ft. bob needs to paint
the room. he has to paint the walls and the ceiling. there are two 3.0 ft. by 5.0 ft. windows and
a 4.0 ft. by 7.0 ft. opening into the room. a gallon of paint covers 320 ft? how many gallons of
paint are needed? explain how you reached your answer. (all data are accurate to two
significant figures.)

Step-by-step explanation:

Let's find the volume of the room in ft³ and that will give

14×22×9=2772ft³

There are deductions. Hence we subtract them from this value

3×5=15, but there are two, hence 15×2=30ft²

And 4×7=28ft²

Hence 2772-(30+28)=2714

Dividing this value by 320 gives

8.4(to 2s.f)

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
