Since the side of the square frame is 15x, the area of the frame in whole would be:

(15x)² = 225x²

Now if we subtract out the circle mirror with a radius of 5x, we get:

225x² - πr²
225x² - π(5x)²
225x² - π25x²

We can factor out a 25x² and get:

25x² (9 - π)

Mrs.Margul paid $125 to have her hair colored and cut if she tips her hairdresser 15% what is her total bill
pantera1 [17]

Answer:

143.75

Step-by-step explanation:

The tip is the cost times the tip rate

tip = cost * rate

The cost is 125  and the rate is 15%

tip = 125 * 15%

Change this to decimal form

tip = 125 *.15

    = 18.75

The total bill is the cost plus the tip

total bill = cost + tip

             = 125 + 18.75

             = 143.75

20/12=15/x find x plz help
Ganezh [65]

Answer:

x = 9

Step-by-step explanation:

To find x, we first have to solve the equation given in the question:

\frac{20}{12} = \frac{15}{x}

20x = 15 \cdot 12

x = \frac{180}{20}

x = 9

Therefore, x = 9.

Hope this helped!
