Andrea uses 9.8 pints of white paint and blue paint to paint her bedroom walls. 1 4 of this amount is white paint, and the rest is blue paint. How many pints of blue paint did she use to paint her bedroom walls?

7.35

Step-by-step explanation:

Andrea uses 9.8 pints of white and blue paints to paint her bedroom walls

1/4 of this amount is white paint

= 1/4 × 9.8

= 0.25×9.8

= 2.45

Therefore the amount of blue paint can be calculated as follows

9.8-2.45

= 7.35

Hence 7.35 are blue paint

b) k’(6, 4); l’(3, 3)

step-by-step explanation:

a 270° clockwise rotation maps every point (x, y) to (y, -x). (it negates the x-coordinate and then switches it and the y-coordinate.)

this means the endpoints of the side congruent to kl, k' and l', would be mapped as:

k'(-4, 6)→(6, 4)

l'(-3, 3)→(3, 3)
