Ariella is selling tickets to a play. adult tickets cost $12.25 and children's tickets cost $8.75. the total amount of money she collects from ticket sales is at least $90.let x represent the number of adult tickets sold. let y represent the number of children's tickets sold. enter an inequality that represents the situation.

List the elements of the set in roster notation. (enter empty or ∅ for the empty set.) {x | x is a letter in the word hippopotamus}

Hurry and answer this! circle x with a radius of 6 units and circle y with a radius of 2 units are shown which steps would prove the circles similar? translate the circles so they share a common center point, and dilate circle y by a scale factor of 4. translate the circles so the center of one circle rests on the edge of the other circle, and dilate circle y by a scale factor of 4. translate the circles so they share a common center point, and dilate circle y by a scale factor of 3. translate the circles so the center of one circle rests on the edge of the other circle, and dilate circle y by a scale factor of 3
