<h2>Answer:</h2>

The new volume that the gas occupy is:

                       20 cubic meters

<h2>Step-by-step explanation:</h2>

Boyle’s law states that the volume of a gas varies inversely with applied pressure.

This means that there exist a constant k such that:

v=\dfrac{k}{p}\\\\i.e.\\\\pv=k

where v is the volume of the gas and is the pressure applied.

This means that if firstly the volume and pressure exerted are:

v_1\ and\ p_1 respectively.

and afterwards the pressure applied and the volume of the gas is:

p_2\ and\ v_2 respectively.

Then by the inverse relation we have:

p_1v_1=k\\\\and\\\\p_2v_2=k\\\\i.e.\\\\p_1v_1=p_2v_2

From the data in the question we have:

v_1=60\ m^3\ ,\ p_1=1\ atm\ ,\p_2=3\ atm

Hence, we have from equation (1)

1\times 60=3\times v_2\\\\i.e.\\\\60=3v_2\\\\i.e.\\\\v_2=\dfrac{60}{3}\\\\i.e.\\\\v_2=20\ m^3

In each part, a and b represent the length of a leg of a right triangle, and c represents the length of its hypotenuse. Find the
Pie

Answer:

c=13 and a=20

Step-by-step explanation:

Here you need to use the Pythagoras theorem :

c²=a² + b²

c = √a² + b²

c = √(12)²+(5)²

c= √144+25

c = √169

c = 13

2) c²=a²+b²

    b= √c²-b²

    b= √(29)²-(21)²

    b = √400

    b = 20

In 2 you change your formula just so that it can be easier and just calculate your length straight forward but you can also just do it in the original equation
