The diagram of the sequence of circular and square tiles gives;

a) 49

b) 84

c) Will always be odd

<h3>Which method can be used to find the order of the sequence in the pattern?</h3>

Pattern 1

Number of square tiles = 1

Number of circular tiles = 8

Total number of tiles = 9

Pattern 2

Number of square tiles = 4

Number of circular tiles = 12

Total number of tiles = 16

Pattern 3

Number of square tiles = 9

Number of circular tiles = 16

Total number of tiles = 25

  • The number of square tiles required to make pattern <em>n </em>= n²

From the diagram, the number of circular tiles on the left or right side of the square tiles are 2 more than the number of square tiles, while the number of circular tiles on the top or bottom are the same as the number of square tiles, therefore;

  • Number of circular tiles = 2•(n + 2) + 2•n

a) The number of square tiles required to make pattern number 7 = 7² = 49

b) The number of circular tiles needed to make pattern number 20 = 2 × 20 + 2 × (20 + 2) = 84

c) The total number of circular tiles is always even while the number of square tiles has the same characteristics (even or odd) as the pattern number

  • Even + Odd = Odd
  • Even + Even = Even

When the pattern number is odd, the total number of tiles will always be odd. The correct option is therefore;

B. Will always be odd

A tree is leaning at a 5° angle from vertical, making an 85° angle with the ground. When the sun is at a 65° angle of elevation,
Vinvika [58]
D = 25 ft is the length of a shadow. L -  the length of a tree.
Two angles are 85° and 65° and the third is 180° - ( 65° + 85° ) =
= 180° - 150° = 30°.
We will use the Sine Law:
25 / sin 30° = L / sin 65°
25 / 0.5 = L / 0.9063
25 * 0.9063 = 0.5 L
22.6577 = 0.5 L
L = 22.6577 : 0.5
L = 45.3 ft.
Answer: the approximate length of the tree is 45.3 ft.
