A is the answer Hope this helps

Hey,
So since a dozen is 12, three dozens is 36.
If 36 cookies = 9 $ we have to divide both sides of equation with 36.
so 1 cookie = $ and 
So a cookie equals to $ and since equals to 0.25, the answer is A) $0.25
Hope this helps, and don't forget to choose the brainliest answer please :)

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 )
