Answer:
2800 tiles
Step-by-step explanation:
Each tile has an area of (0.05 m)² = 0.0025 m². Then the number of tiles required to cover 7 square meters is ...
(7 m²)/(0.0025 m²/tile) = 2800 tiles
It will take 2800 tiles to cover the entryway.
Two squares root. Because 3 * 3 = 9 and -3 * -3 = 9.
Answer:
Please, see attached picture
Step-by-step explanation:
We can easily solve this question by using a graphing calculator or any plotting tool.
The equation is
f(x) = (1/4)*(4)^(x)
Which is an exponential function, that grows rapidly to infinity as x increases.
1+3+5+7+...+999 =
= 1+2+3+4+...+500
+1+2+3+...+499
= 2·(1+2+3+...+499) + 500
= 2·(499·500)/2 + 500
= 499·500 + 500
= 500·(499 + 1)
= 500·500
= 250.000
