Suppose 15% of x equals 20% of y. What percentage of x is y? A 5
B 35
C 75
D 133 1/3
E 300

.15x = .20y, the answer is C bc y is 3/4 of X. We can assume X = 1. And bc Y is 3/4 of X , Y would be 3/4 or .75 . So .15(1)=.20(.75) or .15=.15. Hope this helps

Hope i can you!

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 )
