Which of the following is equivalent to the radical expression below when
Ratling [72]

Answer:

B in the photo

Step-by-step explanation:

another way to write the problem:

square root is also taking the 1/2 power:

(4x)^{1/2} * (x+7)^{1/2} \\

since they are raised to the same power:

(4x * (x+7))^{1/2}\\(4x^2 + 28x)^{1/2}\\\\=\sqrt{4x^2 + 28x}

Suppose you fill the cone with water and empty the water into the cylinder. how many times will you empty the water from the con
Taya2010 [7]
<h3>Answer:  A) 3 times</h3>

=========================================================

Explanation:

Recall that from a previous screenshot you posted, that

\text{Volume of Cone} = \frac{1}{3}*\left(\text{Volume of Cylinder}\right)

If we multiply both sides by 3 and swap both sides, then we end up with

\text{Volume of Cylinder} = 3*\left(\text{Volume of Cone}\right)

So that's why we need 3 cups of water, if each cup is the cone in the diagram. Keep in mind that the height of the cylinder and the cone must be same. The two radius values must be the same as well. You don't need to have r = h be true.
