Find the geometric mean of 4 and 12
jonny [76]

Answer:

The Geometric Mean of 4 and 12 is 6.9

Step-by-step explanation:

Given Numbers are 4 and 12

To find : Geometric mean of the given No.

The Geometric Mean is a type of average where we multiply the nos. together and then take a square root (for two nos), cube root (for three nos) etc.

Formula for Geometric Mean is given by,

Geometric\,Mean\,of\,x_1\,,\,x_2\,,\,x_3..x_n=\sqrt[n]{x_1\times x_2\times x_3\times\,...\,\times x_n}

⇒ Geometric Mean of 4 and 12 = \sqrt{4\times12}

                                                     = \sqrt{48}

                                                     = 4\sqrt{3}

                                                     = 6.92820323028

                                                     = 6.9

Therefore, The Geometric Mean of 4 and 12 is 6.9

The half-life of aspirin is about 3 hours. If someone takes 700mg, how long will it take until less than 50mg is left in that pe
uranmaximum [27]
In 3 hours half of 700 would be 700/2=350

in 3 more hours, so 6 total, the half life would be 350/2 = 175

in 3 more hours, 9 total, the half life would be 175/2 = 87.5

in 3 more hours, 12 total, the live life would be 87.5 / 2 = 43.75

 so it would be 12 hours to have less than 50 mg
