The equation of the sphere is
.. (x -8)^2 +(y +7)^2 +z^2 = 10^2
Then the bottom hemisphere has the equation
.. z = -√(100 -(x -8)^2 -(y +7)^2)
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
My answer is 35 because if you do 3 times 7 then 2 times 7 which equals 21 and 14 then add and you get 35. well that's my answer
