Step-by-step explanation:
x + y = 72
x - y = 40
x = y + 40
so, the first equation is then
y + 40 + y = 72
2y + 40 = 72
2y = 32
y = 16
x = y + 40 = 16 + 40 = 56
300÷2=150 per min, 6750÷45=150, 150 feet per min
Answer:
Volume of cube = 64 m^3
Let the sides of cube = x
So volume = x^3 = 64
It's length is scaled up by a factor of 5.
Each side of the cube will become = 5x
New volume = (5x)^3 = 125 x^3 = 125×64 = 8000 m^3
New volume is 8000 m^3.
