ORDER OF OPERATIONS
step 1. first do operations that accur within_____________.
step 2. then evaluate_________.
step 3. then do_________and_______from left to right.
step 4. finally, do______and_______from left to right.
here are your choices in alphabetical order:
addition
division
exponents
multiplication
parenthesis
subtraction
ask someone or just try to figure it out. post another message with this equation and i will figure it out
For 1. we do operations within () first.
Your step 2. might be exponents, but I'm not sure, there should be something in your text telling you what needs to be done there.
You should know that multiplication, division...addition,subtraction come last.
These are important rules you must know to do algebra well.
i always remember order of operations with the phrase PEMDAS: parentheses, exponents, multiplication, division, addition, and subtraction.
during a science experance mary measures the temp. every 10 min.at 9:00 she recordes 80 degrees. and at 9:10 she recordes 96 degrees what % does the temp. increase during the 10 min. interval from 9:00 to 9:10?
Parentheses
Exponents
Multiplication and division in the order that they appear
Addition and subtraction in the order that they appear
My teachers have a sentence to help me remember this Please Excuse My Dear Aunt Sally
19-4+3÷7=18
To find the percentage increase in temperature during the 10-minute interval from 9:00 to 9:10, you can use the following formula:
Percentage increase = (Change in temperature / Initial temperature) * 100
Let's calculate it step by step:
Step 1: Find the change in temperature.
Change in temperature = Final temperature - Initial temperature
Change in temperature = 96 degrees - 80 degrees
Change in temperature = 16 degrees
Step 2: Find the percentage increase.
Percentage increase = (16 degrees / 80 degrees) * 100
Percentage increase = 0.2 * 100
Percentage increase = 20%
Therefore, the temperature increased by 20% during the 10-minute interval from 9:00 to 9:10.
To find the percentage increase in temperature during the 10-minute interval from 9:00 to 9:10, follow these steps:
Step 1: Calculate the difference in temperature.
Subtract the initial temperature at 9:00 (80 degrees) from the final temperature at 9:10 (96 degrees):
96 degrees - 80 degrees = 16 degrees
Step 2: Calculate the percentage increase.
Divide the difference in temperature by the initial temperature and multiply by 100 to obtain the percentage:
(16 degrees / 80 degrees) * 100 = 20%
Therefore, the temperature increased by 20% during the 10-minute interval from 9:00 to 9:10.
