Sara made $253 for 11 hours of work. at the same rate how much would he make for 7 hours of work?

161

Step-by-step explanation:

253/11=23

23x7=161

$161

Step-by-step explanation:

Take $253/11 so you know how much he makes per hour.

The answer to that is $23.

Then take $23 x 7 hours so you know how much he make for 7 hours

That equals $161.

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
