The number of squares on a chess or checker board is 64 and to find the square root of 64 which is 8*8=64 so the answer is 8
Answer:
5 seconds
Step-by-step explanation:
When the ball returns to its original height, it will be 96 ft from the ground. That means we want to solve for t ...
h(t) = 96
96 +80t -16t^2 = 96
16t(5 -t) = 0 . . . . subtract 96 and factor
This equation is true for t=0 and for t=5.
After 5 seconds, the ball will pass the top of the building on the way down.
Find the total area of the room
109 * 103 = <span>11227 inches^2
the tile takes up 3*3 = 9 inches^2
11227/9 = </span><span>1247.4
You need 1247 tiles and 0.4 of a tile.
Or you could just get 1248 and cut the last tile a bit :P
Hope this helps :)</span>
