The speed of the current in a river is 6 miles per hour
<em><u>Solution:</u></em>
Given that,
Speed of boat in still water = 20 miles per hour
Time taken = 3 hours
Distance downstream = 78 miles
To find: Speed of current
<em><u>If the speed of a boat in still water is u km/hr and the speed of the stream is v km/hr, then: </u></em>
Speed downstream = (u + v) km/hr
Speed upstream = (u - v) km/hr
<em><u>Therefore, speed downstream is given as:</u></em>
We know that,
Speed downstream = (u + v)
26 = 20 + v
v = 26 - 20
v = 6 miles per hour
Thus speed of the current in a river is 6 miles per hour
The correct option is 4. PSU.
The hardware part that would be checked next is PSU.
<h3>What is Power Supply Unit PSU?</h3>
An internal piece of IT hardware is known as a power supply unit (PSU). Despite their name, power conversion devices, or PSUs, do not really supply power to systems.
Some key features of PSU are-
- A power supply specifically transforms alternating high voltage current (AC) to direct current (DC) and regulates the DC output voltage to the precise tolerances needed for contemporary computing components.
- There is, however, a PSU substitute that may be utilized in specific circumstances.
- Electrical power can be transported inside network cables using Power over Ethernet (PoE), freeing the device from being bound to an outlet.
- Because PoE can deliver wireless access points wherever it is most convenient and uses less room for wiring, it is perfect for systems that need greater flexibility.

Answer:
<h2>Model B</h2>
Step-by-step explanation:
The model needs to show 1.8 because 2 x 0.9 = 1.8. Model B is the only model that shows this.

Answer:
x = -5
Step-by-step explanation:
-5(1 - 5x) +5(-8x - 2) = -4x – 8x
First lets simplify each side of the equation.
-5+25x-40x-10 = -4x-8x
Combine like terms
-15x-15=-12x
Add 15x to both sides (addition property of equality)
-15=3x
Divide each side by 3 (division property of equality)
x=-5
The answer is x = -5
