What is the x of 2/3x squared minus 6x plus 15

iogann1982 [59]

(2/3)x^2 -6x + 15 = 0
Using the quadratic formula:
x = [-b +-sq root(b^2 - 4 *a*c)] / 2a
x= [--6 +-sq root(36 -4*(2/3)*15] / 2*(2/3)
x= [6 +-sq root 36 -40] / (4/3)

x1 = 4.5 + (2i / (4/3))
x1 = 4.5 + 1.5i
x2 = 4.5 - (2i / (4/3))
x2 = 4.5 - 1.5i

Michael's rock collection is 27% igneous rock. Half of his collection is sedimentary rock, while the rest is metamorphic rock. H

rjkz [21]

Answer:

23% of Michael's rock collection is metamorphic rock.

Step-by-step explanation:

We are given the following in the question:

Percentage of igneous rock in the collection = 27%

Percentage of sedimentary rock in the collection = 50%

Remaining rocks are metamorphic rock.

Total collection = 100%

Percentage of metamorphic rocks =

$=100\%-(27\%+50\%)\\=100\%-77\%\\=23\%$

Thus, 23% of Michael's rock collection is metamorphic rock.
