On call= 3.5 hours: $10 talk time= 1/2 hour: $1.25 wich company offers the best deal? explain your answer

If this is asking which company is cheaper then that would be talk time because 1/2 an hour costs $1.25 so if you double that it’s 2.50 then double that and you get 5.00. Add 2.50 one more time and you get 7.50 then add 1.25 and you get 8.75. In the end talk time will be cheaper by $1.25

Answer: d. 39 cmin the diagram, the approximate length of the minor arc de is 39 centimetres.step-by-step explanation: the formula for the length of an arc in a circle is as displayed below.let the length of the minor arc de = xx = 2( pi )r × angle of sector / 360°from this, we will substitute the values given from the problem into the formula to obtain the length of the minor arc de.x = 2( pi )r × angle of sector / 360°r = radius = 25cmpi as an approximate value = 3.14angle of sector = 120°x = 2( 3.14 )( 25 ) × 120° / 360°x = 157 × 1 / 4x = 39.25x = 39 ( rounded to the nearest whole number as an approximate value )
