Tickets for a tour of a city cost $5. A tour will only happen when a total of at least 20 tickets and no more than 45 tickets have been sold. The income from ticket sales, y, when there are x tickets sold for the tour can be modeled using a linear function. For one tour, what is the range of the function for this situation? F 0 ≤ y ≤ 20
G 20 ≤ x ≤ 45
H 0 ≤ x ≤ 20
J 100 ≤ y ≤ 225

Nick has box brads. he uses 4 brads for the first project. nick let’s b represent the original number of brads and finds that for the second project, the number of brads he uses is 8 more than half the difference of b and 4. write an expression to represent the number of brads he uses for the second project.

Someone answer asap for ! the boiling point of water at an elevation of 0 feet is 212 degrees fahrenheit (°f). for every 1,000 feet of increase in elevation, the boiling point of water decreases by about 2°f. which of the following represents this relationship if b is the boiling point of water at an elevation of e thousand feet? a. e = 2b - 212 b. b = 2e - 212 c. e = -2b + 212 d. b = -2e + 212

In the diagram, ab is tangent to c, ab = 4 inches, and ad = 2 inches. find the radius of the circle.
