Step-by-step explanation:
Volume of square pyramid
= (Base length)² * (Height/3).
Therefore we have 8 = 2² * (h/3).
=> 8 = 4 * (h/3), h/3 = 2, h = 6.
Hence the height is 6 feet. (1)
Answer:
n=-6
Step-by-step explanation:
5n-42=12n
5n=12n+24
5n-12n=42
-7n=42
divide each side by -7
n does =-6
Gravity is inversely proportional to the square of the distance.
In English:
Your weight at the Earth's surface and your weight 850 miles above the Earth's surface decreases by a factor of
(4,750 / 3,900) ^ 2 =
<span>
<span>
<span>
1.483399080
</span>
</span>
</span>
So your weight would decrease by (your weight /
<span>
<span>
<span>
1.483399080
</span>
</span>
</span>
)
If you weigh 180 pounds, at 850 miles above the Earth your weight is
180 /
<span>
<span>
<span>
1.483399080
</span>
</span>
</span>
which equals

<span>
<span>
121.3429362515

that means he earn $15 in one hour
The solution of the system of equation is (-2 ,2).
<h3>What is a System of Equation ?</h3>
A system of equation is defined as the equation that have a common solution.
The system of equation is
x+y = 0
y = 2x+6
2x-y = -6
3x = -6
x = -2
y = 2
The graph of both the equations are plotted and the common point is the solution of the equations.
The solution of the system of equation is (-2 ,2).
