B the smallest piece of cloth that she can make two squares from is one
that is two squares wide. So if twice the width of the square is the

Answer:
feet : Shark is 72 feet below sea level.
Step-by-step explanation:
Let x represent depth of the shark.
We have been given that the submarine’s depth was twice the depth of the shark. This means that depth of submarine would be 
.
We have been given that a submarine was 144 feet below sea level, so submarine's elevation would be 
.We can represent this information in an equation as:
To find shark's position, we need to solve for x.
Therefore, feet represents shark's elevation, which represents that shark is 72 feet below sea level.
Answer:
20°C
Step-by-step explanation:
Quantity if heat energy supplied is expressed as;
Q = mcΔt
m is the mass = 3kg
Δt is the temperature rise
Q = 5400J
c = 900 J/kg °C
Substitute
5400 = 3(90)Δt
5400 = 270Δt
Δt = 5400/270
Δt = 20°C
Hence the temperature rise is 20°C
