The classification of these numbers into smallest to greatest is -23, -√25, -1/3, 0, π, 4, √22, √400, 51.9, 2.8 * 10^3
<h3>How to classify these numbers into smallest to greatest?</h3>
To do this, we simply evaluate the number expressions
√22 = 4.690
π = 3.142
0 = 0
51.9 = 51.9
√400 = 20
-1/3 = -0.333
-√25 = -5
-23 = -23
4 = 4
2.8 * 10^3 = 2800
Next, we rearrange the numbers from the smallest to greatest
-23 = -23
-√25 = -5
-1/3 = -0.333
0 = 0
π = 3.142
4 = 4
√22 = 4.690
√400 = 20
51.9 = 51.9
2.8 * 10^3 = 2800
So, the classification of these numbers into smallest to greatest is -23, -√25, -1/3, 0, π, 4, √22, √400, 51.9, 2.8 * 10^3

6.37² x 3.1
First is Exponents (6.37²):
40.6 x 3.1
Then, Multiplication:
40.6 x 3.1 = 125.9.
To remember the order of operations, the term PEMDAS can be used. (Parentheses, Exponents, Multiplication, Division, Addition, Subtraction.)
You do the equation in the order of the letters.
Example:
(5-2)5 + 2² / 6 -1 = ?
First, Parentheses:
(3)5 + 2² / 6 - 1
Then, Exponents:
(3)5 + 4 / 6 - 1
Then, Multiplication:
15 + 4 / 6 - 1
Then, Division:
15 + 0.7 - 1
Then, Addition:
15.7 - 1
Then, Subtraction:
14.7
So that means, (5-2)5 + 2² / 6 -1 = 14.7
Answer:
$14.44
Step-by-step explanation:
So lets lay out the information:
The items cost: $13.94
Sales tax: 4%
Step 1, change the percent to a decimal:
To change a percent to a decimal, you move two (2) decimal places to the left. So 4% would be 0.04.
Step 2, figure out 4% of $13.94:
How we do this is we take the decimal and multiply it by $13.94.
0.04*$13.94= $0.55
Step 3, Add the tax amount to the regular amount:
$13.94+$0.55=$14.44
The item cost + sales tax is $14.44
