Answer:
360m3
Step-by-step explanation:
Equation:
v=l*w*h
v=(120)(2)(1.5)
V=360m3
Cross multiply:-
9 * x = 2 * 8
x = (2 * 8) / 9 = 16/9 or 1 7/9 answer
Answer:
130

Answer:
Hope that this is helpful.
Step-by-step explanation:
-3(2x-1)^2+12x^2
= -3[(2x-1)(2x-1)]+12x^2
=-3[2x(2x-1)-1(2x-1)]+12x^2
=-3(4x^2-2x-2x+1)+12x^2
=-3(4x^2-4x+1)+12x^2
=-12x^2+12x-3+12x^2
=(-12x^2+12x^2) +12x-3
=0+12x-3
=12x-3
Answer:
Step-by-step explanation:
50 X 4= 200
90 X 5=450
50 X 5=250
200 + 250 = 450
Therefore it takes 5 hours for train B which is the train moving at 90 km per hr to catch up to train A.
