<em>Ten games</em> will be played.
The first team can be any one of 5 . For each of those, the opponent can be any one of the other 4 .
Number of ways to pair them up = (5 x 4) = 20 ways .
<em>BUT</em> ... Whether the Reds play the Blues, or the Blues play the Reds, it's the SAME GAME. Each possible game shows up twice in the list of 20 ways. So there are really only 10 different pairs ==> <em>10 games</em> .
ThermalThermal relief valve installed in a Hydraulic system will have the highest pressure setting.
<h3>What is the hydraulic system? What are the types of hydraulic systems ? </h3>
Hydraulic system function and perform tasks through using a fluid that is pressurized . There are two types of hydraulic systems open loop hydraulic systems and closed loop hydraulic system . In open loop ,when the actuating mechanism is idle ,there will be fluid flow but no pressure.
Closed loop system use an additional pump called charge pump or feed pump.
Thermal relief valve is Designed to protect the pump and operators in circumstances when the pump is running and the discharge outlets have been closed .

Answer:
48 hours
Explanation:
Using the formula,
R/R' = 2ᵃ/ᵇ..................... Equation 1
Where R = Original amount, R' = Radioactive remain, a = Total time, b = half life.
Given: b = 24 hours,
Let: R = X, then R' = X/4.
Substitute into equation 1
X/(X/4) = 2ᵃ/²⁴
4 = 2ᵃ/²⁴
2² = 2ᵃ/²⁴
Equating the base and solving for a
2 = a/24
a = 24×2
a = 48 hours.
Hence the time = 48 hours
