Eighty-four is what percent of 212? 3.962% 39.62% 2.52% 25.2%

Option B, 39.62%

Step-by-step explanation:

We have to find 84 is what percent of 212.

For this we will put 84 in the numerator and 212 in the denominator to find the fraction first.

Then we will multiply this fraction by 100 to get the percentage.

Fraction of 84 to 212 =

                                  =  

Now the percentage will be

                                        = 39.62%

Option B, 39.62% is the correct answer.

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)
