To find the common ratio, divide the 2nd term by the first term
-16 / 32 = -0.5....this means u multiply each number by -0.5 to find the next number
8 * -0.5 = -4 <==
-4 * - 0.5 = 2 <==
2 * -0.5 = -1 <==
answer D
Irrational numbers can be written as decimals but not as fractions.
0.144 is a decimal, but it can also be written as 18/125. So this is a rational number.
√0.144 is equal to 0.3794733192. It cannot be expressed into a fraction. So, this is an irrational number.
√0.0144 is equal to 3/25. So, this is a rational number.
I hope I was able to help you. Have a good day.
Given :
Every square meter of ceiling requires 10.75 tiles.
To Find :
Number of tiles required at :
Ceiling area Number of tiles
1
10
100
Solution :
For, 1 :
Number of tiles required, n = 10.75 tiles.
For, 10 :
Number of tiles required, n = 10.75 × 10 = 107.5 tiles.
For, 100 :
Number of tiles required, n = 10.75 × 100 = 1075 tiles.
Hence, this is the required solution.
