Answer:

  m = 2k/v

Step-by-step explanation:

Identify the coefficient of m (v/2) and multiply by its inverse (2/v).

  (2/v)k = (2/v)m(v/2) . . . . multiply both sides of the equation by 2/v

  2k/v = m . . . simplify

  m = 2k/v

Type the correct answer in the box. Use numerals instead of words. If necessary, use / for the fraction bar. In the equation√n+5
Yuki888 [10]

Answer:

n = 59

Step-by-step explanation:

The given equation of n is \sqrt{n + 5} - \sqrt{n - 10} = 1 and we have to solve it for n.

\sqrt{n + 5} - \sqrt{n - 10} = 1 ........... (1)

⇒ \frac{(n + 5) - (n - 10)}{\sqrt{n + 5} + \sqrt{n - 10}} = 1  

{Rationalizing the numerator}

⇒ \sqrt{n + 5} + \sqrt{n - 10} = 15 .............. (2)

Now, adding (1) and (2) we get

2\sqrt{n + 5} = 16

⇒ n + 5 = 64 {Squaring both sides}

⇒ n = 59 (Answer)

What is the measure of angle NOP
White raven [17]

For any inscribed quadrilateral, the opposite angles add to 180

(angle PMN) + (angle NOP) = 180

(8x-24) + (4x) = 180

12x-24 = 180

12x-24+24 = 180+24  ..... add 24 to both sides

12x = 204

12x/12 = 204/12 ..... divide both sides by 12

x = 17

angle NOP = 4x

angle NOP = 4*17

<h3>angle NOP = 68 degrees</h3>

45% of a number is 180. Find the number
KonstantinChe [14]

Answer:

81

Step-by-step explanation:

The term "of" can be translated to multiplication in problems like this.

So it's essentially saying multiply 45% to 180 and give me the result.

45% can be written as 45/100 in fractions (45 percent, where cent means 100 and per means division). 45/100 can be written as 0.45 in decimal form.

Now the problem reads 0.45 X 180. Using a calculator, we can solve this and the result comes out to be 81
