The diagram represents the process of creating a scale
drawing from an original using a scale factor of 0.4. the
base of the original drawing must be:
a. 17.6
b. 18 cm
c. 33.5 cm
d. 45 cm

18cm

Step-by-step explanation:

Let original drawing's base be b.

We are using scale factor of 0.4, so

0.4 of b = 7.2cm

0.4 × b = 7.2cm

b = (7.2/0.4)cm

b = 18cm

step-by-step explanation:

. your answer will contain x - and y -terms. (1 point) x ( ¿¿ 2 − 7 ) 2 +( y 2 − 9 ) 2 √ ¿ 12. what is the distance from the directrix (the crocodile river) to the point ( x , y )? write this equation. your answer will contain a y -term.

1; 35 is the ratio
