If Harry has 1,000,000 oranges, and gives 1/2 to Ginny, 1/4 to Hermione, and 1/8 to Ron, how many oranges does he have left.

Step-by-step explanation:

1000000÷2=500000

1000000×.25= 250000

1000000× .08=80000

1000000-500000-250000-80000=620000

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)
