Two concentric circles are expanding in such a way that the radius of the inner circle is
increasing at the rate of 10 cm/sec and that of the outer circle at the rate of 7 cm/sec. At a
certain time, the radii of the inner and the outer circles are respectively 24 cm and 30 cm.
At what time, is the area between the circles increasing or decreasing? How fast?​

Perry has a garden. 1/2 of his garden is planted with tomatoes. 1/3 of his garden is planted with peppers. the remaining part of his garden is planted with flowers. what fraction of perry’s garden is planted with flowers?

How many solutions does the nonlinear system of equations graphed bellow have?

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.
