Answer:
t = 31s
Step-by-step explanation:
................
Explanation:
ratio of two cubes: 2 : 5
Perimeter of one face of cube: 4 × side
For small cube: 4 × 2 = 8
For big cube: 4 × 5 = 20
Ratio of perimeter of one face: 8 : 20 = 2 : 5
Total surface area of cube: 6a²
For small cube: 6(2)² = 24
For big cube: 6(5)² = 150
Ratio of total surface area: 24 : 150 = 4 : 25
Volume of cube: a³
For small cube: (2)³ = 8
For big cube: (5)³ = 125
Ratio of volume: 8 : 125
Answer:
q = -5
q = 5
Step-by-step explanation:
Since there is no constant value. This must be a special case.
So,
(q+5)(q-5)
q = -5
q = 5
Split 60 minutes into 3 groups. 20+20+20=60 minutes. 20 minutes
