2 m³ of soil containing 35% sand was mixed into 6 m³ of soil containing 15% sand. What is the sand content of the mixture?

Alex17521 [72]

.2 m^3 is 10 percent
.2 m^3 is 10 percent
.2 m^3 is 10 percent
.1 m^3 is 5 percent
therefore
.7m^3 is 35%

.6m^3 is 10%
.3 m^3 is 5%
so .9m^3 is 15 %

all in .9m^3 +.7m^3 = 1.6 m^3 will be sand

Using the quadratic formula to solve 11x²-4x=1 What are The values of X?

Anvisha [2.4K]

$11x^2 - 4x = 1$
$11x^{2} - 4x - 1 = 1 - 1$
$11x^{2} - 4x - 1 = 0$
$x = \frac{-(-4) \± \sqrt{(-4)^{2} - 4(11)(-1)}}{2(11)}$
$x = \frac{4 \± \sqrt{16 + 44}}{22}$
$x = \frac{4 \± \sqrt{60}}{22}$
$x = \frac{4 \± 2\sqrt{15}}{22}$
$x = \frac{2 \± \sqrt{15}}{11}$
$x = \frac{2 + \sqrt{15}}{11}\ \bold{or}\ x = \frac{2 - \sqrt{15}}{11}$
