I'm not at my desk and can't check it out right now.
But I think you should try 10 and -42 .
Use Photomath or desmo to give you the answer
First, find the difference between the original price and the reduced price;
65 - 45 = $20 difference
Then, divide the difference by the original amount;
20/65 ≈ 0.3077
Then, multiply this by 100 to convert the decimal into a percentage;
0.3077 * 100 = 30.77%
The percent of change would be about 30.77%
The length in standard notation is 2.17 + 8 = 10.17 ft
<h3>How to write in standard notation? </h3>
A standard notation is a form of writing a given number, an equation, or an expression in a form that follows certain rules.
For example 9.5 billions years can be represented as follows;
9,500,000,000 years.
Therefore, let's write 8 ft and 26 inches in standard form.
12 inches = 1 ft
26 inches = ?
cross multiply
length(ft) = 26 / 12
length(ft) = 2.16666666667
length(ft) = 2.17 ft
Therefore, the length in standard notation is 2.17 + 8 = 10.17 ft
