Write each percent as a fraction and as a mixed number or fraction 325% 480% 0.6%
ExtremeBDS [4]

325%=3.25 which is \frac{325}{100} or 3\frac{25}{100} which can be reduced to 3\frac{1}{4}

480%=4.80 which is \frac{480}{100} or 4\frac{80}{100} which can be reduced to 4\frac{4}{5}

0.6%=0.006 which is \frac{3}{500}

I hope this helps.

2x + y 2 =6<br> 3x-2y2 = -5
Yuliya22 [10]

Answer:

  (x, y) = (1, ±2)

Step-by-step explanation:

To solve this pair of equations, one can add the second equation to twice the first:

  2(2x +y^2) +(3x -2y^2) = 2(6) +(-5)

  4x +3x = 12 -5 . . . . simplify a bit

  7x = 7 . . . . . . . . . . . collect terms

  x = 1  . . . . . . . . . . . . divide by 7

Then y can be found from the first equation:

  y^2 = 6 -2x = 6 -2(1) = 4

  y = ±√4 = ±2

The solutions are ...

  (x, y) = (1, -2)   or   (1, 2)

Which shows all the exact solutions of sin^2 x + 3cos x - 1 = 2?
Zarrin [17]

Answer:

x = 2k\pi is the solution of this equation.

Step-by-step explanation:

This question is related to trigonometric equations.

The given equation is,

sin^{2} x + 3cos x - 1 = 2

We have to find the solutions of this equation.

Put sin^{2}x  = 1 - cos^{2}x

1 - cos^{2}x + 3cosx - 1 = 2

cos^{2}x -3cosx+2 = 0

For this equation only cosx = 1 is possible solution.

Cosx = 1 happens when x is a multiple of 2\pi

So x = 2k\pi is the solution of this equation.
