Applying the rule that a number is divisible by 9 if the sum of its digits is divisible by 9, we find that 504 and 882 from the list (115, 504, 968, 646, 882) are divisible by 9.
To identify numbers that are divisible by 9, we can follow this rule: A number is divisible by 9 if the sum of its digits is divisible by 9. So, applying this rule to the numbers given (115, 504, 968, 646, 882), we find:
115: 1+1+5 = 7, which is not divisible by 9.
504: 5+0+4 = 9, which is divisible by 9. So 504 is divisible by 9.
968: 9+6+8 = 23, which is not divisible by 9.
646: 6+4+6 = 16, which is not divisible by 9.
882: 8+8+2 = 18, which is divisible by 9. So 882 is divisible by 9.

feet, how many such tiles will he need?
A) 144, B) 1152, C) 1728, D) 9216, E) 20736
Plz help me with this problem.. :-(
The number of tiles required to completely cover the floor is A) 144.
We know the perimeter of any 2D figure is the sum of the lengths of all the sides except the circle and the area of a rectangle is the product of its length and width.
We know the area of a rectangle is (length×width).
Given, His room is a rectangle, measuring 12 feet by 18 feet,
Therefore, The area of the room is
= (12×18) sq feet.
= 216 sq feet.
Also given one measures 3/4 inches by 2 inches.
Therefore the area of one tile is,
= [3/4×(2)] sq inches.
= 3/2 sq inches.
So, The number of tiles requires is the area of the room divided by the area of one tile which is,
= (216/(3/2)).
= 216×(2/3).
= 144 tiles.
