Answer:
5 cm
Step-by-step explanation:
The volume (V) of a cuboid is calculated as
V = lbh ( l is length, b is breadth and h is height )
Here l = 20, h = 12, V = 1200 and b is to be found, thus
20 × b × 12 = 1200, that is
240b = 1200 ( divide both sides by 240 )
b = 5
Answer:
The bike costs $130.
Step-by-step explanation:
1) 200 x 0.35 = 70
2) 200 - 70 = 130

Answer: 4 litres of air is held in Braydon’s tank.
Step-by-step explanation:
The law relating pressure to volume is the Boyle's law. It states that the volume of a given mass of gas is inversely proportional to its pressure as long as temperature remains constant. It is expressed as
P1V1 = P2V2
Where
P1 and P2 are the initial and final pressures of the gas.
V1 and V2 are the initial and final volumes of the gas.
From the information given,
V1 = 6 litres
P = 220 psi
P2 = 330 psi
Therefore,
6 × 220 = 330V2
V2 = 1320/330 = 4 litres
