If a recipe uses 3 ½ cups of flour for ½ the recipe, how much flour is needed for the entire recipe?

It needs 7cups of flour

3 1/2+ 1/2.

If you make the mixed number an improper fraction by multiplying the whole to the denominator and then add the numerator. This would be your new numerator, but then keep the original denominator. But since this is working with halves you could easily do this

1/2+1/2= 1 3+1= 4 cups of flour for the whole recipe

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 )
