HELPPPPPPPPP i have the most trouble with math what’s the answer??
lakkis [162]

Answer:

Second Option

\frac{5\sqrt{11} +5\sqrt{3}}{8}

Step-by-step explanation:

To simplify the expression you must multiply the numerator and the denominator of the fraction by the conjugate of the denominator.

If you have an expression of the form

a -b then its conjugate will be a + b.

The result of that multiplication will be

a ^ 2 -b ^ 2

Therefore we have the expression

\frac{5}{\sqrt{11} -\sqrt{3}}

By multiplying by the conjugate of the denominator we have

\frac{5}{\sqrt{11} -\sqrt{3}}*\frac{\sqrt{11} +\sqrt{3}}{\sqrt{11} +\sqrt{3}}\\\\\\\frac{5(\sqrt{11} +\sqrt{3})}{(\sqrt{11})^2 -(\sqrt{3})^2}\\\\\\\frac{5\sqrt{11} +5\sqrt{3}}{11 -3}\\\\\\\frac{5\sqrt{11} +5\sqrt{3}}{8}

A sphere has a volume of approximately 113 cubic units. Which of the following best represents the radius of the sphere?
Kitty [74]

Answer:

H. 3 units

Step-by-step explanation:

In order to answer this question, we have to apply the formula for the sphere volume. The formula is:

V=\frac{4}{3} \pi r^{3}

Plugging the given number into V, we calculate that:

113 = \frac{4}{3}\pi r^{3}\\84.75 = \pi r^{3}   \\

If π=3.14, the radius is:

r ≈ 3 units.
