To find the best estimate for the percentage just divide 64/75 and you should get 85.3% and you can round that to 85%.

Use the quadratic formula to determine the exact solutions to the equation <br> 6x^2 + 4x - 3 = 0
mezya [45]
To solve quadratics, the most correct and effective way, in my opinion, is the quadratic formula:

{\displaystyle x={\frac {-b\pm {\sqrt {b^{2}-4ac}}}{2a}}.}<span><span>

Plugging it in, we get:

</span></span>\frac{-4\pm \sqrt{16+72} }{12}  =  \frac{-4\pm 2\sqrt{22}}{12} =  \frac{-2\pm \sqrt{22} }{6}

So the final answer is:

\frac{ \sqrt{22}-2 }{6} and \frac{-2- \sqrt{22} }{6}

The main tank has a radius of 70 feet. What is the volume of the quarter-sphered sized tank? Round your answer to the nearest wh
Misha Larkins [42]
Volume of a sphere with radius of 70 feet is:
V =  \frac{4}{3} * \pi * r^{3}

where r is that radius

Because we need quarter sized tank of that radius we need to divide formula for volume by 4

Than we get:
V =  \frac{1}{3} * \pi * r^{3}

V = 359188,76

Rounded:
V = 359189
