When line sets have been altered, they may not be treated as self-contained systems of their own?

Answers

First of all, you may alter line sets. When you do, the nitrogen charge is released into the atmosphere.
You can then pressure the lines with a tracing gas in order to check if there are leaks in the connections you've made.
After the test is complete, you have to evacuate the line set before opening the valves to start the system.

Knowing this, we can say that line sets, when altered, may NOT be treated as self-contained systems of their own is a FALSE statement.

For what side length(s) is the area of an equilateral triangle equal to 30 cm?? Only enter the number, in centimeters, rounded to two decimal places. A cm ►

Answers

Answer: The sides length are 8.32 cm

Step-by-step explanation:

An equilateral triangle has all his sides of the same lenght, so we assume that the triangle has an L lenght in his sides.

The area of a triangle isArea = (base * height)/(2)where the base is L, the Area is 30 and an unknown height.

To determine the height, we cut the triangle in half and take one side. By simetry, one side has a base of (L)/(2), a hypotenuse of L and a the unknown height.  

Then we apply the Pythagoras theorem, this states that in a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides, or, hypotenuse = \sqrt{c^(2) + c^(2) }Where one c is (L)/(2) and the other is the height.

Then we find one of the c of the equation wich will be the height.

height = \sqrt{hypotenuse^(2)-base^(2) }

height = \sqrt{ L^(2) -(L)/(4) ^(2)}\nheight = \sqrt{( 3L^(2))/(4) } \n\nheight = (√(3)L )/(2)

Finally, we use the triangle area mentioned before an find the value of L.

30 = (L*(√(3)L )/(2) )/(2) \n\nL = \sqrt{(120)/(√(3) ) } \n\nL = 8.32 cm
