Answer:
Empirical formula= COOH
Step-by-step explanation:
Molecular mass of the elements
Carbon= 12
Oxygen= 16
Hydrogen= 1
We divide the elements each with their molecular formula
Carbon= 2.4/12
Carbon= 0.2
Oxygen= 6.4/16
Oxygen= 0.4
Hydrogen= 0.2/1
Hydrogen= 0.2
Now we divide with the smallest result which is 0.2
Carbon= 0.2/0.2
Carbon = 1
Oxygen= 0.4/0.2
Oxygen= 2
Hydrogen= 0.2/0.2
Hydrogen= 1
So we have
Carbon 1, oxygen 2, hydrogen 1
Empirical formula= COOH
Answer:
11%
Step-by-step explanation:
A sales tax is placed on goods and services once the buyer and seller agree on what the exchange of currency is.
In this case you take the tax on the 1625 and not the 1803.75.
The buyer agreed to buy the item for 1625 and the seller agreed to sell it for that amount. So the tax goes on 1625.
Tax amount = total price - selling price
Tax amount = 1803.75 - 1625
Tax amount = 178.75
That's not what you want. You want the % of the tax.
% Tax = (Tax Amount / Selling Price) * 100
% Tax = (178.75 / 1625) * 100
% Tax = 0.11 * 100
% Tax = 11% Answer
Step-by-step explanation:
Let the length of the bridge be x
Since, triangles ADF and BCF are similar, ratio of their corresponding sides are equal.
Therefore,
60 / 144 = 40 / x
X (length of the bridge) = <u>96 m</u>
Answer:
3
Step-by-step explanation:
It should be 3 because when you look at it divide them all and each one gives you 3. If it's not then sorry.
