9 is 36 percent of what number?

25

Step-by-step explanation:

25 times 0.36 is 9

9 divided by 0.36 equals 25

25

Step-by-step explanation:

let the number be x

36% of x = 9

(36/100) * x = 9

removing the bracket

36x/100 = 9

multiply both sides by 100

36x = 9 x 100

36x = 900

divide both sides by 36

36x/36 = 900/36

x = 25

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)
