Step-by-step explanation:
Notice that both equation has a 2f term in them
solve for 2f for both eqs.
2f= 736-6n
2f= 920-10n
since they both equal to 2f, yo can set them equal to each other
736-6n = 920-10n
and solve for n if you want
To find the volume of this sphere you use the equations 4/3 times pi times r^3
For this question it would look like this 4/3 * 3.14 * 8^3=v
The answer is v = 2144.66058
Answer:
1) 24
2) 36
3) 144
Step-by-step explanation:
Order of operations are the operations in which you must complete multiple-operation equations.
Here's an acronym to help you remember the order of operations.
PEMDAS:
- Exponentiation (exponents)
----------------------------------------------------------------------------------------------------------------
7 × 3 + (18 - 9) ÷ 3
First, as stated by the order of operations, solve what is in parenthesis.
7 × 3 + (18 - 9) ÷ 3
7 × 3 + 9 ÷ 3
-------------------------------------------------------------------------------------------------------------
There are no exponents.
Further, we solve the multiplication problem(s).
7 × 3 + 9 ÷ 3
21 + 9 ÷ 3
-------------------------------------------------------------------------------------------------------------
Moreover, we solve the division problem(s).
21 + 9 ÷ 3
21 + 3
-------------------------------------------------------------------------------------------------------------
Lastly, we solve the remaining addition problem(s).
21 + 3
24
-------------------------------------------------------------------------------------------------------------
Now, we solve the remaining equations using order of operations (PEMDAS).
(7 × 3) + (18 - 9 ÷ 3)
21 + (18 - 9 ÷ 3)
21 + 18 - 3
39 - 3
36
-------------------------------------------------------------------------------------------------------------
7 × (3 + 18) - 9 ÷ 3
7 × 21 - 9 ÷ 3
147 - 9 ÷ 3
147 - 3
144
