Answer: NO (222 SEATS IS LESS THAN 255 SEATS )

Step-by-step explanation:

1 first-class section

The first-class section has 14 seats.

5/7 are being used = 5/7 * 14 seats = 10 seats

Unused seats = 14 seats - 10 seats = 4 seats

1 business-class section

The business-class section has 64 seats.

5/16 are being used = 5/16 * 64 seats = 20 seats

Unused seats = 64 seats - 20 seats = 44 seats

4 economy-class sections

Each economy-class section has 108 seats.

Each economy-class section has 108 seats.

5/9 in each section are being used  = 4 * ( 5/9 * 108) = 240 seats

Unused seats in 4 economy - class section = 4*108 - 240 = 192 seats

Total seats in an airbus = 1 first-class section + 1 business-class section + 4 economy-class sections

Total seats in an airbus = 14 + 64 + 432 = 510 seats

used seats in an airbus = 1 first-class section + 1 business-class section + 4 economy-class sections

used seats in an airbus = 10+20 +  192 = 222 seats

half of total seats = 510/2 = 255 seats

used seat = 222 seats

222 seats < 255 seats

Thus NO

Answer:

The hexagon has an area of 220.6 square units.

Step-by-step explanation:

You can solve this by realising that the hexagon can be divided into 6 equilateral triangles of the same area.

The area of the triangle is the same as a rectangle of the same width and height, but divided by two, and we're told that the width of the side is 9.2, and the height is eight.  So the total area of the hexagon is:

6 × (9.2 × 8) / 2

= 9.2 × 24

= 220.6

So the hexagon has an area of 220.6 square units.
