The answer is: $19.56
4 * $4.89= $19.56
Here, I’ve answered this question before:
Standard form is Ax + By = C where A and B are coefficients to x and y respectively
So we have to move y to the right side and 3 to the left side, because 3 is the constant in this case, and therefore the C of our equation.
Since the sign changes after moving them over the equation, y and 3 will both be negative
-3 = 1x - y
It helps to draw a picture so you can visualize it better.
For the rug, since the area = 144, what two numbers multiplied give you 144? You might already know that 144 is a perfect square, so 12 x 12 = 144. 12 is the length of each side of the rug.
√144 = 12
12 + 3 = 15. (Add 3 because the rug only covers a portion of the floor. The entire floor = the length of the rug + the part that isn't covered)
15 x 15 = 225 ft squared (Multiply both sides of the floor to get the area.)
225 ft squared - 144 ft squared = 81 ft squared <-- your answer
(ANSWER IS): 24% I’m pretty sure this is the correct answer
Answer:
![xy^\frac{2}{9} = x*\sqrt[9]{y^2}](https://tex.z-dn.net/?f=xy%5E%5Cfrac%7B2%7D%7B9%7D%20%3D%20x%2A%5Csqrt%5B9%5D%7By%5E2%7D)
Step-by-step explanation:
Given
![xy^\frac{2}{9}](https://tex.z-dn.net/?f=xy%5E%5Cfrac%7B2%7D%7B9%7D)
Required
The equivalent expression (see attachment)
We have:
![xy^\frac{2}{9}](https://tex.z-dn.net/?f=xy%5E%5Cfrac%7B2%7D%7B9%7D)
Split
![xy^\frac{2}{9} = x*y^\frac{2}{9}](https://tex.z-dn.net/?f=xy%5E%5Cfrac%7B2%7D%7B9%7D%20%3D%20x%2Ay%5E%5Cfrac%7B2%7D%7B9%7D)
Apply the following laws of indices
![y^\frac{m}{n} = \sqrt[n]{y^m}](https://tex.z-dn.net/?f=y%5E%5Cfrac%7Bm%7D%7Bn%7D%20%3D%20%5Csqrt%5Bn%5D%7By%5Em%7D)
So, we have:
![xy^\frac{2}{9} = x*\sqrt[9]{y^2}](https://tex.z-dn.net/?f=xy%5E%5Cfrac%7B2%7D%7B9%7D%20%3D%20x%2A%5Csqrt%5B9%5D%7By%5E2%7D)
<em>Hence (d) is correct</em>
