Answer:because...
Step-by-step explanation:
they are the same size and both can reflect on eachother .
Write down the decimal divided by 1, like this: decimal 1. Step 2: Multiply both top and bottom by 10 for every number after the decimal point. (For example, if there are two numbers after the decimal point, then use 100, if there are three then use 1000, etc.) Step 3: Simplify (or reduce) the fraction.
Step-by-step explanation:
the price is 5 per tile ?
the area of the rectangular room is
12×6 = 72 m²
each m² has 100×100 = 10000 cm²
so, we have for the total area in cm²
72 × 10000 = 720000 cm²
one tile has 10×2 = 20 cm²
so, how many tiles will we need ?
720000 / 20 = 72000 / 2 = 36000 tiles.
so, if truly 1 tile costs 5 Rupees, then we have
36000 × 5 = 180000 Rupees as total costs.
<h3>Answer:</h3>
<h3>Explanation:</h3>
You can try the choices to see which one works. The differences between an values double each time. They have the sequence 1, 2, 4, 8. So, you know that choices A) and D) do not work. They show the difference to be constant at 1 or 8. Since the differences are multiplied by 2, C) is a reasonable choice. Trying that, we find it describes the sequence perfectly:
a2 = 2·2 -1 = 3
a3 = 2·3 -1 = 5
a4 = 2·5 -1 = 9
a5 = 2·9 -1 = 17
___
Trying choice B on the last term, we have
... a5 = 3·a4 -3 = 3·9 -3 = <em>24 ≠ 17</em>
