Huck finn can paint a fence in 5 hours. after some practice, tom sawyer can now paint the fence in 6 hours. how long would it take huck and tom to paint the fence together?

2.72 hours

Step-by-step explanation:

Data provided:

Time taken by Huck Finn to paint the fence = 5 hours

Time taken by Tom to paint the fence = 6 hours

Now,

Fence painted in 1 hour by Huck Finn = of total fence

and,

Fence painted in 1 hour by Tom = of total fence

Therefore,

Total fence painted together by Huck and Tom in 1 hour = +

or

Total fence painted together by Huck and Tom in 1 hour =

or

Total fence painted together by Huck and Tom in 1 hour =

Hence,

Time taken by Huck and Tom to together paint the fence =  

= 2.72 hours

d 25 pi/6

step-by-step explanation:

the diameter is 10 inches

the radius is 1/2 of the diameter or 5 inches

the area of the circle is

a = pi r^2

  = pi 5^2

  = 25 pi

the slice is 60 degrees of the entire circle.

60 degrees out of 360   60/360 = 1/6

the area of the slice is 1/6 of the circle

a slice = 1/6 a circle

a slice = 1/6 * 25 pi

2(2x + 3) = -4 + 2(2x + 5)

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 6

4x - 6 + 6 = 4x - 6 + 6

4x = 4x

x = x
