Answer:
Step-by-step explanation:
V of a cube is s^3
V = 512
s = cube root of (V)
s = cube root of 512 cm^3
s = 8
The area of one face of the cube is s^2
s = 8
Area 1 face = 8^2
Area of 1 face = 64 cm^2

Answer:
x = 16.5
Step-by-step explanation:
2x + 3y = 73.50
5x + 2y = 109.50
(2x + 3y = 73.5) -5
(5x + 2y = 109.5) 2
-10x - 15y = -367.5
10x + 4y =219
-11y = -148.5
y = 13.5
2x + 3(13.5) = 73.50
2x + 40.5 = 73.5
2x = 73.5 - 40.5
2x = 33
x = 16.5
Answer:90minutes
Step-by-step explanation:
Speed=distance/time
Speed=40miles per hour, distance=60miles
40=60/t
Cross multiply
40t=60
Divide both sides by 40
40t/40=60/40
t=1.5 hour =90minutes
Answer:
x=7
Step-by-step explanation:
