Answers that are way off the answer you came up with can automatically be eliminated because those are most likely trick answers people can fall for. Rounding or estimating can ensure your answer by a slight chance.

The answer above is not going to get you anywhere.

Most of the time you should estimate when you have a long decimal.

The area of an equilateral triangle is LaTeX: 108\sqrt[]{3}\:ft^2 108 3 f t 2 . What is the length of one side of the triangle?
Temka [501]
The length of one side is 12√3.

We know that the area of a triangle is given by the formula:

A=1/2(b)(h)

We can substitute the area in:
108√3 = 1/2(b)(h)

Let b be the side of the equilateral triangle.  To find the height, we will use the Pythagorean theorem.  We know that the height bisects the base, so we will call that leg of the right triangle formed (1/2b).  Since the triangle is equilateral, we will call the hypotenuse b as well.  We now have:

(\frac{1}{2}b)^2+h^2=b^2&#10;\\&#10;\\\frac{1}{4}b^2+h^2=b^2&#10;\\&#10;\\\frac{1}{4}b^2+h^2-\frac{1}{4}b^2=b^2-\frac{1}{4}b^2&#10;\\&#10;\\h^2=\frac{3}{4}b^2&#10;\\&#10;\\\sqrt{h^2}=\sqrt{\frac{3}{4}b^2}&#10;\\&#10;\\h=\frac{\sqrt{3}}{2}b

We will now substitute this in the formula for area we had above:
108√3=(1/2)(b)(√3/2b)
108√3=√3/4b²

Multiply both sides by 4:
(108√3)×4=(√3/4b²)×4
432√3=√3b²

Divide both sides by √3:
432√3/√3 = √3b²/√3
432=b²

Take the square root of both sides:
√432=√b²

Simplifying the radical, we have 12√3.

PLEASE HELP!!!!! What values complete each statement? Enter your answers in the boxes. (16‾‾‾√)2 = _ in simplest form. By the Po
mario62 [17]

We are given expression: (\sqrt{16})^2.

Square root in exponent form is power \frac{1}{2}.

Therefore, \sqrt{16} = 16^{1/2}.

Now, replacing square root of 16 by 16^{1/2} in original expression we are given, we get

(\sqrt{16})^2 = (16^{1/2})^2 = (16)^2/2 = 16.

Therefore,

<h3> (\sqrt{16})^2= 16 in simplest form. By the Power of Power rule, (16^{1/2})^2=16^{2/2} . So, 16^{1/2} must equal\sqrt{16} in radical form.</h3>
