Answer: Ok!
Step-by-step explanation:
Here is website with great explaination but it has long and confusing words so im going to simplify it: It is a thought.co and search percent error
Lets choose an example: (9) The percent error formula is | Estimate-Acual | divided by Actual.
These lines / | / are absolute value lines so that means anything inside thoses are positive.
So let use (9), plugin values, |80-62| / 62 80-62=18 18/62= .29 To get percents you multiply that by 100 to get 29.03% or 29%
Lets do one more: I choose (16), let plugin value into the formula: Wait we have a fraction, you can't have fractions in percents so we just change it into a decimal. Continue: | 42.5-50| / 50. Ok, 42.5-50=-7.5 but with absolute value marks, it is just 7.5. so it is 7.5/50= 0.15 times 100 is 15%
Comment below if there are any questions that are confusing and I can just answer them there!
This question seems to be a good example of why we need to learn math!
P=present value
i=interest rate = 0.02 per year
time, t=1 year
we need P such that
interest = Pit ≥ 9.99
or
P(.0002*1) ≥ 9.99
=>
P ≥ 9.99/0.0002 = 49950
Answer: it takes a minimum balance of $49950 to cover a "below minimum balance fee" of $9.99.
Answer:
3 1/3 ÷ 4/5 = 25/6 =4 1/6
Result in decimals: 4.1666666666667
Answer:
3 pounds (1.36 kg) of coffee purchased.
Step-by-step explanation:
Since she started with $80 and ended with $58.01 we can find the total amount she spent by subtracting these amounts:
$80 - $58.01 = $21.99
This means that she spent $21.99 on coffee. If each pound cost $7.33, we can divide $21.99 by $7.33 to see how many pounds she bought:
21.99 / 7.33 = 3 pounds (1.36 kg) of coffee purchased.
Hope this helps you!
Have a good evening!
