Answer:
V=4/3*πr^2 is the same as V=four-thirds pi &(7) cubed
Step-by-step explanation:
Hey there!
The answer to your question is z > -4
We can solve this like it is an equation, with one exception. When you divide or multiply by a negative number, in an inequality, you have to flip the inequality sign.
-2z - 3 < 5 add 3 to both sides
-2z < 8 divide both sides by -2, and flip the inequality sign
z > -4
Good luck! Hope it helps, and have a great day!
Yes both rates are equivalent
Answer:
Therefore
![75\div 5 - [(9-7)\times 3 ]\times 2 = 3](https://tex.z-dn.net/?f=75%5Cdiv%205%20-%20%5B%289-7%29%5Ctimes%203%20%5D%5Ctimes%202%20%3D%203)
Step-by-step explanation:
To Find:
Value of expression
75 ÷ 5 - [( 9 - 7 ) × 3 ] × 2
Solution:
PEDMAS rule
It explains the order of operations to solve an expression.
According to Pedmas rule, if an expression contains brackets ((), {}, []) we have to first solve or simplify the bracket followed by of (powers and roots etc.),
then division, multiplication, addition and subtraction from left to right.
P - parenthesis
E- exponent
D/M - Div or Multiply which ever comes first
A/S - Add or Sub which ever comes first.
So first we will solve the Parenthesis we get
Step 1. Parenthesis operation
75 ÷ 5 - [( 2 ) × 3 ] × 2
Step 2. Parenthesis operation
![75\div 5 - [(2)\times 3 ]\times 2](https://tex.z-dn.net/?f=75%5Cdiv%205%20-%20%5B%282%29%5Ctimes%203%20%5D%5Ctimes%202)
Step 3. Division
![15 - [6]\times 2](https://tex.z-dn.net/?f=15%20-%20%5B6%5D%5Ctimes%202)
Step 4. Multiplication

Step 5. Subtraction
3
Therefore
![75\div 5 - [(9-7)\times 3 ]\times 2 = 3](https://tex.z-dn.net/?f=75%5Cdiv%205%20-%20%5B%289-7%29%5Ctimes%203%20%5D%5Ctimes%202%20%3D%203)
