Total power generated by wind worldwide doubles every 3 years. In a particular year, the world wind-generating capacity was abou

NeTakaya

This is a problem of doubling time, the general formula for doubling time is

N = A(2)^( t /d)
where N is the future wind generating capacity in thousand MW
A is the initial wind generating capacity which is 95,000 MW
d is the time it will double, which is 3 years
t is the time in the future in years

N = 95(2)^( t / 3) is the formula for t<span>he continuous growth rate and give a formula for wind generating capacity W W (in thousand megawatts) as a function of t t , the number of years in the future</span>

Working alone Ryan can dig a 10ft by 10ft hole in five hours castel can dig the same same hole in six how long would it take the

Sergeeva-Olga [200]

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 $\dfrac{1}{z}$ = $\dfrac{1}{x}$ + $\dfrac{1}{y}$

Or, $\dfrac{1}{z}$ = $\dfrac{1}{5}$ + $\dfrac{1}{6}$

<u>Taking LCM</u>

Or, $\dfrac{1}{z}$ = $\dfrac{6 + 5}{30}$

Or, $\dfrac{1}{z}$ = $\dfrac{11}{30}$

Or, z = $\dfrac{30}{11}$ 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
