Determine where each point is located in the coordinate plane. Place a check in the appropriate box for each point. (3,4 ) (-3,2) (-4,-5) (5,-4) (-5,0) (0,4)

Let r = 3. what is the value of r + 58?

The volume of a sphere is increased by 6%. calculate the corresponding percentage increased in it area.

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.
