The temperature started at 89°f. if the temperature went up 6°f and then down 12°f, whats is the temperature difference relative to the high temperature?

89 degrees plus 6, minus 12, equals 83.  This means that the temperature change would be 89 - 83, which equals 6.  There is a 6 degree temperature change.

5   1/4   miles per hour

step-by-step explanation:

15   3/4 / 3 = 5   1/4

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
