7 pipes fill a tank in 50 minutes. How many minutes does it take if there are 11 pipes?
Alekssandra [29.7K]

Answer: With 11 pipes, you need 31.82 minutes to fill the tank.

Step-by-step explanation:

Let's define R as the rate at which one single pipe can fill a tank.

We know that 7 of them can fill a tank in 50 minutes, then we have the equation:

7*R*50min = 1 tank

Whit this equation, we can find the value of R:

R = 1 tank/(7*50min) = (1/350) tank/min.

Now that we know the value of R, we can do the same calculation but now with 11 pipes.

Then the time needed to fill the tank, T, is such that:

11*(1/350 tank/min)*T = 1 tank

We need to isolate T.

T = 1 tank/(11*(1/350 tank/min)) = 31.82 min

With 11 pipes, you need 31.82 minutes to fill the tank.

The definition of a circle uses the undefined term _______.
Alecsey [184]

Answer:

C. Plane  

Step-by-step explanation:

One definition of a circle is: "It is the set of all points in a plane that are at a given distance from a fixed point."

The undefined term is the word "plane."

You could define a plane as a flat surface with zero thickness and extends infinitely in all directions, but it isn't in the definition of a circle.

Euclid defined a plane as "a surface that lies evenly with the lines on it" before he defined a circle, so the meaning was understood.

A, B, and D are wrong. They aren't mentioned in the definition.
