Answer:
Depends on which place you're rounding to:
Step-by-step explanation:
Rounded to the tenths place (one number after the decimal point):
x = -6.6, -9.4
Rounded to the hundredths place (two numbers after the decimal place):
x = -6.59, -9.41
Rounded to the thousandths place (three numbers after the decimal place):
x = -6.586, -9.414
I don't think you'd need to round to the ten-thousandths place. If you do lemme know and I'll edit my answer. But you should know if the next digit is 5 or greater like in 15 you'd round up. If it's less than 5, you round down.
Answer:
So the annual percent of decay is: 7.77%
Step-by-step explanation:
If the value of a car was $18000 in 2006, and in 2016 it was worth $4000 it means, it lose 77.77% of its value in 10 years.
To calculate the percentage of decay we use the rule of three:
If the price of the car in 2006 ($18000) represents 100%, then, how much does $4000 represents?
4000*100/18000 = %22.22
Now, we know that $4000 represents 22.22% the original value, so it lose 100% - 22.22% = 77.77% of its value.
So the annual percent of decay is: 77.77% / 10 = 7.77%
