Determine what the next equation would be, and verify that it is indeed a true statement.50 - 9 = 41500 - 89 = 4115000 - 789 = 4211
A. 50,000 - 6,789 = 493,211 B. 500,000 - 6,789 = 43,211 C. 5000 - 6,789 = 43,211 D. 50,000 - 6,789 = 43,211
Solve the problem.Determine the measure of the angle in each point of the six-pointed star appearing on police badges and vehicles. (Hint: Inscribe the star in a circle, and use the following theorem from geometry: An angle whose vertex lies on the circumference of a circle is equal to half the central angle that cuts off the same arc. See the figure.)
A. 45° B. 60° C. 75° D. 90°
