One day, david hands out flyers to 7 people. the next day, each person copies the flyer and hands them out to 7 people. the following day, these people copy their flyer and hand them out to 7 people.

how many people now have flyers?

On the first day, David hands out flyers to 7 people. So 7 people have flyers.
The Next day, each person of this 7 people hands flyers to 7 other people: So it's 7*7 = 49. So 49 people have now flyers.
The following day, each of this 49 people gives flyers to 7 people: So it's 49*7=343.

So At last, 343 people have now flyers.

Hope this Helps! :)

Add them all together then u will get your answer

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 )
