Honestly I just looked it up
The law of cosines states that:
c^2=a^2+b^2-2abcosC
You already have all the values for the variables with the exception of x so:
x^2=25+100-100cos60
x=√(125-100cos60)
x=√75
x≈8.66 to nearest one-hundredth...
Answer:
C
Step-by-step explanation:
Because a unit fraction is like 1/1 1/2 1/3 1/4 1/5
and all of those start with 1 so it is C. 1/32
Answer: Lol your in collage I don't believe it anyway the answer is 20 min on the dot
The first pipe operates at rate of (6600 L / 66 min) = 100 L/min.
The second pipe operates at a rate of (6600 L / 55 min) = 120 L/min.
Working together, both pipes operate at a total rate of 220 L/min.
Then the time it takes for both of them to fill the tank is
(6600 L) * (1/220 min/L) = 30 min
