Answer:

720 balls

Step-by-step explanation:

Can = 3 balls

Box = 4 cans = 4*3balls = 12 balls

Case = 6 boxes = 6* 12balls = 72 balls

10 cases = 10 *72balls = 720 balls

Answer: 720

Step-by-step explanation:

If there are 10 cases and 6 boxes in a case. Multiply 10 by 6 to get 60.

Then if there are 4 cans in a box. Multiply 4 by 60 to get 240.

Finally, if there are 3 tennis balls per can. Multiply 240 by 3 to get 720.

There are 720 Tennis Balls in 10 Cases.

Y = –x + 4
aliina [53]
Y = -x + 4.....so sub in -x + 4 in for y in the other equation

x + 2y = -8
x + 2(-x + 4) = -8
x - 2x + 8 = -8
x - 2x = -8 - 8
-x = -16
x = 16

y = -x + 4
y = -16 + 4
y = - 12

one solution (16,-12)

The approximate length of rail that needs to be replaced is 7.1 ft

<h3>Length of arc</h3>

Since the pool is circular, the approximate length that needs to be replaced is an arc of length, L = Ф/360° × πD where

  • Ф = central angle of rail section = 27° and
  • D = diameter of circular pool = 30 ft

<h3>Approximate length of rail</h3>

So, substituting the values of the variables into the equation, we have

L = Ф/360° × πD

L = 27°/360° × π × 30 ft

L = 3/40 × π × 30 ft

L = 3/4 × π × 3 ft

L = 9/4 × π  ft

L = 2.25 × π  ft

L = 7.07 ft

L ≅ 7.1 ft

So, the approximate length of rail that needs to be replaced is 7.1 ft
