Which pipe configuration can deliver more water to

Stels [109]

Answer: One 8-cm pipe (Its is greater than the total area of of two 4-cm pipes)

Step-by-step explanation:

The area of a circle can be calculate with this formula:

$A=\pi r^2$

Where "r" is the radius of the circle.

We need to calculate the area of 8-cm pipe. In this case:

$r=8cm$

Then, substituting the radius into the formula, we get:

$A=\pi (8cm)^2\\\\A=201.06cm^2$

Now we must calculate the area of the two 4-cm pipes.

Since they are two pipes, the formula is:

$A=2\pi r^2$

In this case:

$r=4cm$

Then, substituting into the formula, we get:

$A=2\pi (4cm)^2\\\\A=100.53cm^2$

Therefore, since the area of one 8-cm pipe is greater than the total area of of two 4-cm pipes, we conclude that the pipe configuration that can deliver more water to residents is:

One 8-cm pipe

How do i solve (ax+bx)/3=c in terms of a and b and c

elena-s [515]

The problem is already in terms of c.
ax+bx/3=c

ax+bx=3c
x(a+b)=3c
a+b=3c/x
a=3c/x +b or b=3c/x -a
