A biology teacher plans to produce a twelve-question quiz, using a test bank consisting of 15 true/false questions 20 multiple choice questions, and 10 free response questions. (5 points) Suppose the teacher wanted the quiz to have exactly four questions of each type. How many different quizzes could be produced

the answer is 8

step-by-step explanation:

3.14 x 8x8

it is a. 4.2 because 7.6-3.4 gets the remaining length of 4.2. i might be wrong but i am pretty sure this is the answer.

maybe i can

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°
