N A resistor is a device that has a designed resistance to the
passage of electric current. Resistors are said to be
connected in parallel if they share a common terminal for
each of their ends. If you have only two resistors in parallel,
total resistance R can be calculated as a function of the
two individual resistors a and b:
ab
R =
a + b
Rearrange the formula to find b.

Solve the triangle. a = 21°, c = 105°, c = 5

Tom is the deli manager at a grocery store. he needs to schedule employee to staff the deli department for no more that 260 person-hours per week. tom has one part-time employee who works 20 person-hours per week. each full-time employee works 40 person-hours per week. write and inequality to determine n, the number of full-time employees tom may schedule, so that his employees work on more than 260 person-hours per week. graph the solution set to this inequality.
