Tennis balls are packed into a square box 12 in. on one side. the tennis balls can be touching, but they can't be compressed. the remaining space is filled with packing beads.

how many tennis balls can be packed onto the box? (note: the diamenter of a tennis balls is 2.5 in.)

what is the volume occupied by the packing beads?

Adriveway is 60-feet long by 6-feet wide. the length and width of the driveway will each be increased by the same number of feet. the following expression represents the perimeter of the larger driveway: (x + 60) + (x + 6) + (x + 60) + (x + 6) which expression is equivalent to the expression for the perimeter of the larger driveway? a) 2(x + 66) b) 4x + 33 c) 4(x + 33) d) 4(x + 132)

Asmall business produces and sells balls. the fixed costs are $20 and each ball costs $4.32 to produce. each ball sells for $8.32. write the equations for the total cost, c, and the revenue, r, then use the graphing method to determine how many balls must be sold to break even.

What is the solution to this system of equations? y= 2x - 3.5 x - 2y = -14
