Answer:
1,675.516
Step-by-step explanation:
The formula for a cone is V = pi r^2 h/3.
Plugging in the values of the radius and height, V = pi 10^2 16/3
Solving, you get:
V = pi 100 5.3333333
V = 1,675.516

Answer:
x=7
Step-by-step explanation:
Start by distributing the 3:
(3)(x)+(3)(−2)=22-x
Now we have:
3x−6=−x+22
Add x to both sides:
3x−6+x=−x+22+x
Now we have:4x−6=22
Add 6 to both sides:
Add x to both sides.
3x−6+x=−x+22+x
4x−6+6=22+6
Now we have
4x=28
Divide both sides by 4
x=7
For simplicity sake, let's call Train A "A" and Train B "B".
A + B = 192
A > B
A - B = 120
192 ÷ 2 = 96
96 ± 120 ÷ 2 = 96 ± 60 = 156, 36
Train A weighs 156 tons and Train B weighs 36 tons :)
