How would you scale down by a factor of 1/10?

slavikrds [6]

Answer:

See example below.

Step-by-step explanation:

To scale down by a factor of 1/10, multiply the side length or distance by 1/10.

Example:

If the distance was 5 then 5*1/10 = 5/10 = 1/2 is the scaled down version.

HELP PLEASE!! ASAP <br> If triangles ABC and DEF are similar, what is y? Show your work.

Ivenika [448]

Answer:

y = 18

Step-by-step explanation:

Since the triangles are similar, the corresponding sides are in proportion, that is

$\frac{BC}{EF}$ = $\frac{AC}{DF}$ , substitute values

$\frac{y}{12}$ = $\frac{21}{14}$ ( cross- multiply )

14y = 252 ( divide both sides by 14 )

y = 18
