Answer: 200
Equation: 175 × 5 + 225 × 5 ÷ 10 = 200
Explanation: to find the average, you add up all the numbers, then divide by how many numbers there are.
I do not understand what your asking. Tell me the question.
The volume of a sphere is
V_s = 4/3 * pi * r_s^3
The volume of a cone is
V_c = 1/3 * pi * h * r_c^2
Since we know that the two volumes are equal, we can say
V_s = V_c
4/3 * pi * r_s^3 = 1/3 * pi * h * r_c^2
Let us now isolate r_c, the radius of the cone:
4/3*r_s^3 = 1/3 *h*r_c^2
sqrt((4*r_s^3)/h) =r_c = 12 cm
So the radius of the cone is 12 cm
Answer:
Quadratic Equations! Yes!
Step-by-step explanation:
Now, there are three methods to solving this:
1.Quadratic Formula
2.Factoring
3. Completing the square
Now, Based on the answers, I think it would be better if we used Quadratic Formula, as you cannot get the answer easily with factoring, and I'm a bit rusty on completing the square.
So, Quadratic Formula! To solve it using this method, we have to find x using this:
(the +- before the square root means it could be both positive or negative)
Where a, b are coefficients and c is a term(in a quadratic equation form:
)
So, we just have to input the stuff from our equation into the formula!

Now, we can simplify the square root of 32 into 4 times the square root of 2

And, we can divide 2 from it all!

So, there you have it! The Answer is C, or 3.
Hope this helps!
