This is PEMDAS as well as order of operations and or parentheses, exponents, multiplication, division, addition, and subtraction. Multiplication and division go together, so you do whichever one comes first. Same goes to addition and subtraction. A way to remember the order is Please Excuse My Dear Aunt Sally.
Answer:
C. 48.
Step-by-step explanation:
If the mean is 12, then 12 must be 2x, 3x, 4x, and 3x divided by 4.
--> 
--> 
--> 
--> x=4
Add: 2x+3x+4x+3x=8+12+16+12=48
Answer:
Your answer would be 254.47
Step-by-step explanation:
Here, you can use this formula A=πr2
No, you cannot use the Associative properties with either subtraction and division, because it will not end to the same result. 14-8 is not the same as 8-14, and 24/4 is not the same as 4/24, but for example 3+2 is the same as 2+3.
Answer:
3.98 cm, 602.18 cm²
Step-by-step explanation:
<u>Given:</u>
<u>To find:</u>
<u>Solution:</u>
- V = πr²h
- h = V/πr² = 800/(π8²) = 3.98 cm
- S = 2πr (r+h) = 16π(8+3.98) = 602.18 cm²
