The coordinates of the vertices of AHKM are H(2.0). K(8, 1), and M(3, 4). After a translation, the coordinates of
the vertices of the image of AHKM are H(-2-5), K (4. -4).
and M(-1-1). What translation was performed on AHKM?
(x, y) = (x-4, y-5)
B (x, y) → (x-1 y+8)
(x, y) = (x+4. y+5)
(x, y) → (x+1 y-8)

1) c 2143.6 cm

2) c 113.0 m

3) a 33.5 ft

4)   d 2 cm

5) c 20 mm

6) 180 in

7) d 120 ft

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl

b. 153 students do not participate in sports and seventy-five 12th graders were surveyed

sorry not knowing about that
