Answer:
62 cubic yards
Step-by-step explanation:
<em>This is conversion from feet to yards.</em>
<u>Step 1: Write the ratio of yards to feet.</u>
Yard : Feet
1 : 3
<u>Step 2: Find out the volume of mould</u>
1 : 3
x : 186
<em>Cross multiply</em>
3x = 186
x = 62 yards
Therefore, 62 cubic yards of concrete is needed in order to fill the mould.

Step 1) Distribute everything in parentheses by <em>8</em><em>.</em>
<em>16w-8-4w=-116</em>
Step 2) Combine like terms
<em>12w-8=-116</em>
Step 3) Add <em>8</em><em> </em>to both sides
<em>1</em><em>2</em><em>w</em><em>=</em><em>-</em><em>1</em><em>0</em><em>8</em>
Step 4) Divide
Answer: <em>-</em><em>9</em>
The equation of a circle is (x - h)² + (y - k)² = radius²
where the center is represented by (h, k).
So to plug in:
(x - (-2))² + (y - 1)² = radius²
(x + 2)² + (y - 1)² = radius²
To find the radius, you can do the distance formula OR (and I suggest this one) use common sense. The center and point given have the same Y-value meaning they are in a horizontal line. Because of this, you can just find the distance between them (AKA your radius) by doing the absolute value of their difference:
|- 4 - (-2)| = |- 4 + 2| = |-2| = 2
Just to show order doesn't matter:
|- 2 - (-4)| = |- 2 + 4| = |2| = 2
Your radius is 2. Plug this into your equation and simplify.
(x + 2)² + (y - 1)² = (2)²
Your answer is:
(x + 2)² + (y - 1)² = 4
