What is 25% of 50? Is it,
A- 200
B- 10
C- 25
D- 12.5

Describe the 2 algebraic methods you can use to find the zeros of the function f(t)=-16t^2+400.

Which of the following are accepted without proof in a logical system? check all that apply.

If m∠abc = 70°, what is m∠abd? justify your reasoning.  using the addition property of equality, 40 + 70 = 110, so m∠abd = 110°.  using the subtraction property of equality, 70 − 30 = 40, so m∠abd = 30°.  using the angle addition postulate, 40 + m∠abd = 70. so, m∠abd = 30° using the subtraction property of equality.  using the angle addition postulate, 40 + 70 = m∠abd. so, m∠abd = 110° using the addition property of equality.
