students are measuring an object with a mass of 38. If one student measures it as 41, what is the percent of error?

42.4

step-by-step explanation:

convert to decimal

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)

no because mercury has a density of 13.6 grams per centimeter squared while gold has 19.32 grams centimeter squared
