Help me please. I dknt understand math I’m du. mb

A mixed number is a whole number with a proper fraction together.

With that definition, keep the 2. It is already a whole number.

0.81 is the part you need as a proper fraction. 0.81 can be read as 81 hundredths or 81/100.

So combine the two: 2 81/100 is 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 )
