What is the length of the hypotenuse of the triangle?

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.

Fast! find the length of cu. the triangles are similar. show your work.

Each unit cost 14p, how much would 942 units cost?
