Francesca is getting balloons for her father's birthday party. She wants each balloon string to be 9 feet long. At the party store, string is sold by the yard. If Francesca wants to get 67 balloons, how many yards of string will she need? 1 foot = 1 3 yard

7839 yards

Step-by-step explanation:

Francesca wants each balloon string to be 9 feet long.

She wants to get 67 balloons.

The total length of string she will need (in feet) is:

67 * 9 = 603 feet

The store sells string by the yard.

1 foot = 13 yards

Hence, the length of string she will need in yards will be:

603 * 13 = 7839 yards

She will need 7839 yards of string.

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
