Twelve glass beakers have a solution of hydrochloric acid of different quantities. the amount of solution, in milliliters, in each glass beaker is shown.

{15, 10, 16, 6, 20, 8, 22, 14, 9, 13, 27, 25}

what is the range in the quantity of hydrochloric acid?

21

Step-by-step explanation:

the range is the highest minus the lowest

27-6=21

Option C

Step-by-step explanation:

By the property of a rectangle,

"All interior angles of a rectangle measure 90°"

Therefore, m∠ABC = 90°

By applying cosine rule in the right triangle ABC,

cos(∠CAB) =

cos(25°) =

AC =

AC =

AC = 19.86

Therefore, Option C will be the answer.
