The lines are perpendicular
Step-by-step explanation:
4x-2
+2
so that leaves 4x
divide by four
x = 1
Answer: The total number of games sold by the GameStop is 14. That is 5 games of $43 and 9 games of $30.
Step-by-step explanation:
Considering some games of $43 were sold and others for $30 were also sold in arriving at the total of $485 sold.
If 5 games of $43 were sold it gives $215.
To get the difference, you subtract the amount sold for $43 from the total.
$485 - $215 = $270
To arrive at how many $30 games were sold;
$270 ÷ $30 per game = 9 games
Therefore, 5 games of $43 combined with 9 games of $30 gives a total of 14 games.
I think I know what it forms - a cone!!
I'm guessing that the angles at the end are 10 degrees so that would make angle CAB equal 5 degrees.
Line AB would be the radius of the "upper cone".
Line BC is 12/2 or 6
tangent (A) = BC / AB
tangent (5) = 6 / AB
AB = 6 / tan(5)
AB = 6 / 0.087489
AB =

68.58 which is the radius of the "upper cone".</span></span></span>
Cone Volume = (PI * radius^2 * height) / 3
Cone Volume = (PI * 68.58 * 68.58 * 6) / 3
Cone Volume =

29,551
That is just the "upper cone volume. So, we multiply </span></span></span><span><span>

29,551 * 2
and get 59,102 which is the volume of the entire solid.
