The percentage is 85 percent
see the attached figure to better understand the problem
we know that
The equilateral triangle has three equal sides
so
in the equilateral triangle ABC
![AB=BC=AC=16 units](https://tex.z-dn.net/?f=AB%3DBC%3DAC%3D16%20units)
the height of the triangle is the segment BD
in the right triangle BCD
Applying the Pythagorean Theorem
![BC^{2} =BD^{2}+DC^{2}](https://tex.z-dn.net/?f=BC%5E%7B2%7D%20%3DBD%5E%7B2%7D%2BDC%5E%7B2%7D)
solve for BD
![BD^{2}=BC^{2}-DC^{2}](https://tex.z-dn.net/?f=BD%5E%7B2%7D%3DBC%5E%7B2%7D-DC%5E%7B2%7D)
substitute the values
![BD^{2}=16^{2}-8^{2}](https://tex.z-dn.net/?f=BD%5E%7B2%7D%3D16%5E%7B2%7D-8%5E%7B2%7D)
![BD^{2}=192](https://tex.z-dn.net/?f=BD%5E%7B2%7D%3D192)
![BD=\sqrt{192}\ units](https://tex.z-dn.net/?f=BD%3D%5Csqrt%7B192%7D%5C%20units)
therefore
<u>the answer is</u>
the height of the triangle is ![\sqrt{192}\ units](https://tex.z-dn.net/?f=%5Csqrt%7B192%7D%5C%20units)
I think this is the answer
A)Cathy had $6 at first
B)Selena has $24 at first
Hi there!
Let’s take a look at the question.
One can of paint contains 2 2/5. We can make it easier by transforming the fraction (2 2/5) to a decimal (2.4). Now you have 2.4. Next, it says “one dozen”. One dozen refers to 12 cans. You’ll want to multiply 2.4 with 12.
Your answer is 28.8, or 28 4/5.
Hope this helps!
