Answer:
it's C
Step-by-step explanation:
i took the test and got it right
Quantity of animal feed in the barn initially = 96 kg
Fraction of animal feed that was wasted = 1/10 of initial quantity
Quantity of animal feed wasted= (1/10) *96 = 9.6 kg
Quantity of animal feed left = Quantity of animal feed initially - Quantity of animal feed wasted
Quantity of animal feed left = 96-9.6= 86.4 kg
Answer: 86.4 kg of animal feed was left in the barn.
This would be 4/9 since You can divide both by ten and nothing else after that due to the fact that they both end in 0 and are multiples of 10 making the answer 4/9
Answer:
Suppose the next case.
You want to buy an object from another state or country, you know that the cost of this object is C, and for bringing it from another place, you need to pay a tax, such that you do not know the exact value of the tax, you know that this can be between 3% and 9%.
Then the tax can be written as:
6% ± 3%
then the error is 3%, this means that the percent error is:
(3%/6%)*100% = 50%
Then you know that there is an error of 50% in the tax.
This can be helpful so you can estimate the maximum and minimum cost of tax that you will pay for this purchase.
Also there are a lot of situations where the percent error give us a lot of information.
"a measure of 10 cm with an error of 1 cm"
The percent error is: (1cm/10cm)*100% = 10%
And in a measure of 3cm with an error of 1cm we have:
(1cm/3cm) = 33.33%
In both cases we have the came error, but different percent error.
Then the percent error also tell us how much the error affects our measure.
