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

Volunteers for a political campaign gave out 21/38 of their fliers. They gave out the remaining 612 fliers in another neighborho

dmitriy555 [2]

The volunteers gave 1368 fliers in total.

Step-by-step explanation:

Given,

Fliers given by volunteers in first neighborhood = $\frac{21}{38}$

Remaining fliers = 612

Fraction of remaining fliers = $1-\frac{21}{38}=\frac{38-21}{38}$

Fraction of remaining fliers = $\frac{17}{38}$

Let,

x be the total fliers given by volunteers.

$\frac{17}{38}\ of\ x=612$

$\frac{17}{38}x=612$

Multiplying both sides by $\frac{38}{17}$

$\frac{38}{17}*\frac{17}{38}x=612*\frac{38}{17}\\\\x=\frac{23256}{17}\\\\x=1368$

The volunteers gave 1368 fliers in total.

Root of 108 is between______ and ______

natita [175]

Without using a calculator I would say the root is between 10 and 11

How I found the answer:
I know 10 * 10 = 100
I know 11 * 11 = 121
So the root of 100 = 10 and the root of 121 = 11 so that means the root of 108 is somewhere between 10 and 11, which the root of 108 = 10.3923
