Answer:

Step-by-step explanation:

800 tiles

Step-by-step explanation:

Area of the tiles = Length × Breadth

= 13 × 7

= 91 cm²

Area of the rectangular region = Length × Breadth

= 520 × 140

= 72800 cm²

Therefore the number of tiles needed to cover the rectangular region

= Area of the rectangular region ÷ Area of the tiles

= 72800 cm² ÷ 91 cm²

= 800 tiles

Hope it helps

grin007 [14]

9514 1404 393

Answer:

  12 dimes

Step-by-step explanation:

Let q represent the number of quarters. Then the number of dimes is 16-q and the total value is ...

  0.25q +0.10(16 -q) = 2.20

  0.15q +1.60 = 2.20 . . . . . . . simplify

  0.15q = 0.60 . . . . . . . . subtract 1.60

  q = 4 . . . . . . . . . . . divide by 0.15

  16-q = 12

There are 12 dimes in the collection.
