3/5 is the correct answer for sin s
<u>Answer:</u>
<em>Equation is 4x-6(6x-1) = -11
</em>
<u>Step-by-step explanation:</u>
<em>The set of equations given are
</em>
<em>6x-y=1
</em>
<em>4x-3y=-11
</em>
A pair of linear equations in <em>two variables x and y is given</em> in the set of equations. If there are two variables we require two equations to find the <em>value of variables</em>. Substitution is one among the methods used to solve pair of linear equations in two variables.
Here we have to <em>determine the value of y</em> from the first equation and then substitute it in the second equation.
<em>6x-y=1
</em>
<em>y=6x-1
</em>
<em>Substituting this value in second equation 4x-6y=-11 </em>
<em>we get </em>
<em>4x-6(6x-1) = -11
</em>

Answer:
6042915 balls.
Step-by-step explanation:
Volume of a ping pong ball is;
V = (4/3)πr³
diameter of ping pong ball is given 4cm = 0.04 m
Radius; r = 0.04/2 = 0.02 m
V = (4/3)π(0.02³)
V = 0.00003351032 m³
Room is 9.5 meters long, 7.5 meters wide, and 3 meters high.
Volume; V = 9 × 7.5 × 3 = 202.5 m³
Number of ping pong balls that will fit into the room = volume of room/volume of ping pong balls = 202.5/0.00003351032 = 6042914.540956151
Approximately 6042915 balls.
