Answer:
The time taken by both when they work together is 2 hours 42 minutes .
Step-by-step explanation:
Given as :
The time taken by Ryan to dig 10 ft by 10 ft hole = x = 5 hours
The time taken bu Castel to dig 10 ft by 10 ft hole = y = 6 hours
Let The time taken by both when they work together = z hours
<u>According to question</u>
The time taken by both when they work together = time taken by Ryan to dig 10 ft by 10 ft hole + time taken bu Castel to dig 10 ft by 10 ft hole
i.e =
+
Or, =
+
<u>Taking LCM</u>
Or, =
Or, =
Or, z = hours
∴ z = 2 hours 42 minutes
So, The time taken by both when they work together = z = 2 hours 42 min
Hence, The time taken by both when they work together is 2 hours 42 minutes . Answer

The LED which would glow brightest is LED C with the greatest current and voltage
The LED which would be the most dim is LED B with low voltage and consequently low current.
<h3>How to determine the current</h3>The formula for finding current
I = V/R
Where v = voltage
R = resistance
A. V = 12V
R = 4. 7 + 15 = 19. 7 kΩ = 19700 Ω in series
×
A
B. V = 9V
R = 4. 7 + 1 = 4. 7 kΩ = 4700Ω in series
×
A
C. V= 12V
1/R = =
×
R = = 310. 56 Ω
A
It is important to note that the brightness of a bulb depends on both current and voltage depending on whether the bulb it is in parallel or series.
The LED which would glow brightest is LED C with the greatest current and voltage
The LED which would be the most dim is LED B with low voltage and consequently low current.
