To calculate the percentage increase:
First: Find out the difference (increase) between the two numbers you are comparing.
It is computed by: Increase = New Number - Original Number
Second: Divide the increase by the original number and multiply the answer by 100.
It is computed by: % increase = Increase ÷ Original Number × 100.
So in the problem:
First step:Increase = 1000 – 100
Increase = 900
Second:
% increase = 900 / 100 x 100%
increase = 900% increase
B)
así que si usted toma el número sesenta dos entonces se obtiene cuarenta y seis
Answer:
A and B are correct
Step-by-step explanation:
Answer:
Number of carbon atoms present in the sample are 391.
Step-by-step explanation:
We are given that,
Ratio of carbon to hydrogen atoms = 1 : 4
It is given that a sample of methane consists of 1564 hydrogen atoms.
Let the carbon atoms in the sample = x
So, we have the relation,
i.e.
i.e.
i.e. x= 391
Hence, the number of carbon atoms present in the sample are 391.
