Quadrilateral DEFG has vertices D(−2,4) , E(4,7) , F(10,3) , and G(8,0) .
fredd [130]

A rotation 270° counterclockwise about the origin is the same as rotation 90° clockwise about the origin and has a rule:

(x,y)→(y,-x).

Then:

  • D(−2,4)→D'(4,2)
  • E(4,7)→E'(7,-4)
  • F(10,3)→F'(3,-10)
  • G(8,0)→G'(0,-8)

Answer: the coordinates of vertices of quadrilateral D′E′F′G′ are D'(4,2), E'(7,-4), F'(3,-10), G'(0,-8).

The Rodriguez family and the Hill family each used their sprinklers last summer. The water output rate for the Rodriguez family'
brilliants [131]

Answer:

x = 23.33 hr    Rodriguez sprinkler

y  = 26.66 hr   Hill sprinkler

Step-by-step explanation: INCOMPLETE QUESTION

Requiered information:

the water output rate for both sprinkler families

We assume : Rodriguez family   40 lts/hr

                      Hill family   35 lts/ hr

Total water output  1900 lts

and total combined hours working is 50 hr

Let call  "x"  time in hours sprinkler of Rodriguez family worked

and "y" time in hours sprinkler of  Hill  family worked

Then if total output was 1900 lts

40*x  +  35*y  = 1900    and   x  +  y  =  50

We have a two equation system, solving

y  =  50 - x     ⇒     40*x  +  35 * ( 50 - x )

40x  =  1750 -  35x

75 x  =  1750        ⇒    x  = 1750/75          ⇒    x = 23.33 hr

and   y  =  50  -  23.33     ⇒   y  =  26.66 hr
