Answer:
We conclude that it would take 4.5 minutes to fill the full barrel.
Step-by-step explanation:
It is stated that it took 3/4 of a minute to fill a barrel 1/6 full of water.
- It means if it took 0.75 minutes to fill the 1 part out of 6 parts.
It is conditioned that the water continues at the same rate.
so
Total parts of a barrel = 6
It takes 0.75 minutes to fill the 1 part of a barrel
Thus, multiply 0.75 by 6 will determine the total time in minutes to fill all the 6 parts of a barrel (or a full barrel).
i.e.
0.75 × 6 = 4.5 minutes.
Therefore, we conclude that it would take 4.5 minutes to fill the full barrel.
Answer:
a = 94
b = -66√3

Given z = 
![(-1-i\sqrt{3})^6=[(-1-i\sqrt{3})^3]^2](https://tex.z-dn.net/?f=%28-1-i%5Csqrt%7B3%7D%29%5E6%3D%5B%28-1-i%5Csqrt%7B3%7D%29%5E3%5D%5E2)
![=[-(1+i\sqrt{3})^3]^{2}](https://tex.z-dn.net/?f=%3D%5B-%281%2Bi%5Csqrt%7B3%7D%29%5E3%5D%5E%7B2%7D)
![=[(1+i\sqrt{3})^3]^2](https://tex.z-dn.net/?f=%3D%5B%281%2Bi%5Csqrt%7B3%7D%29%5E3%5D%5E2)
![=[(1)^3+(i\sqrt{3})^3+3(1)^2(i\sqrt{3})+3(1)(i\sqrt{3})^2]^2](https://tex.z-dn.net/?f=%3D%5B%281%29%5E3%2B%28i%5Csqrt%7B3%7D%29%5E3%2B3%281%29%5E2%28i%5Csqrt%7B3%7D%29%2B3%281%29%28i%5Csqrt%7B3%7D%29%5E2%5D%5E2)
[(a + b)³ = a³ + b³ + 3a²b + 3ab²]
= [1 + 3i² + 3i√3 + 9i²]²
= [1 - 3 + 3i√3 - 9]²
= [-11 + 3i√3]²
= (11)² -2(3i√3)(11) + (3i√3)²
= 121 - 66i√3 + 27i²
= 121 - 66i√3 - 27
= (94 - 66i√3)
Comparing it with (a + bi),
a = 94 and b = -66√3
Hi! so in order to do this problem, you need to figure out what percent 76 is of 80. you can do this by dividing 76 by 80! so just do 76/80, and convert to a percent!
