For this case we have to:
x: Represents the unknown number
y: Represents the exponent of base 10
So, considering a system of equations we have:

From the first equation we have:

Substituting in the second equation:

We choose the positive value:

So, the number is 0.4.
So:

Thus, the exponent is 5.
Answer:
Yara use 0.4 and
Answer:
300
Step-by-step explanation:
6 × 10¹ ÷ 2 × 10-¹
= 300
no of aluminium is 300 times more than that of gold
It is given that Sylvia sells x number of bottles and Sam sells three times as many bottles as Sylvia sold to his co-workers.
So, number of bottles Sam sold is 3x.
It is also given that, number of remaining bottle Sylvia and Sam have same.
So,
24 - x = 36 - 3x
3x - x = 36 - 24
2x = 12
x = 6
Therefore, Sylvia sells 6 bottles.
Hence, this is the required solution.
10.5^2 + 20.8^2 = 110.25 + 432.64 = 542.89
23.3^2 = 542.89
Right triangle
------------------------
20.1^2 = 524.41
6^2 + 20.1^2 = 36 + 404.01 = 440.01
Not a right triangle
