20 goes in to 8 2.5 times
It's an equation with no solution.
A solution is the number that 'x' must be in order to
make the equation a true statement.
Subtract 3x from each side, and you have -1 = +7
There's NO value for 'x' that can make that statement true.
So the equation has no solution.
Answer:
<em>Line 2 ║ Line 3</em><em> </em>
Step-by-step explanation:
y = mx + b
~~~~~~~~~~
Line 1: <em>y = - 7x + 6</em>
Line 2: x + (1/3)y = - 6 ⇔ <em>y = - 3x - 18</em>
Line 3: <em>y = - 3x - 8</em>
Line 4: y + 7 = (-1/7)(x + 4) ⇔ <em>y = </em><em> x - </em>
= ⇒ <em>Line 2 ║ Line 3 </em>
Firstly, calculate for the radius from the given circumference. The equation for circumference (C) is,
C = 2πr ; r = C/2π
Substituting the given circumference,
r = 50ft/2π = 25/π ft
The area for the solving the surface area of a sphere is calculated through the equation,
SA = 4πr² = 4π(25/π)² = 795.77 ft²
Therefore, the surface area is approximately 795.77 ft².
