Lubov Fominskaja [6]

Answer:

The total number of visitors on Thursday was 400.

Step-by-step explanation:

So, we know that there were 220 visitors who were under the age of 12, and that the amount of visitors under the age of 12 was 55% of the total number of visitors. This means that 220 was 55% of the number of visitors. To find the total number of visitors, we divide the number of visitors under the age of 12 (220) by 0.55 (55%).

220/0.55 = 400

The total number of visitors on Thursday was 400.

I hope you find my answer helpful. :)

Please help me with this math problem

First and foremost that is a quadrilateral, because it is a 4-sided figure.  If it was a trapezoid it would have only 1 set of parallel lines.  So NOT a trapezoid.  It is a parallelogram because parallelograms have 2 pair of parallel lines.  It is not a rhombus because a rhombus has 4 equal length sides.  So it's not a square either.  It is not a rectangle either because rectangles have 4 right angles and this one does not.  So your choices are 1 and 3.
