Express the ratio 45 seconds to 30 minutes as a fraction in simplest form. a. 3 c. 40 d. 1

 c  40

Step-by-step explanation:

1 minute = 60 seconds

30 minutes = 1800 seconds

45/1800 = 9/360 = 1/40 = 40

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)
