Question
Chapter 76, Problem 1A
To determine
To show:
The right triangle that contains the angle T.
To show:
The right triangle that contains the given angles.
Expert Solution & Answer
Explanation of Solution
Given information:
A diagram with top view, front view and size view has given.
Calculation:
Rectangular solid form by the given blocks.
Top view, front view and side view are given for the solid pyramid. When these blocks are combined with each other than that form a rectangular solid, which contain angle R and angle T with some right angles.
Here angle MBO is right angle which is formed by top view.
Angle OBN is right angle which is formed by side view.
Angle R is formed at right-angle triangle MNB andright-angle triangle ONB in which angles are given.
Angle T is formed atright angle triangleBMO and right-angle triangle BMO.

Hanson Inn is a 96-room hotel located near the airport and convention center in Louisville, Kentucky. When a convention or a special event is in town, Hanson increases its normal room rates and takes reservations based on a revenue management system. A large professional organization has scheduled its annual convention in Louisville for the first weekend in June. Hanson Inn agreed to make at least 50% of its rooms available for convention attendees at a special convention rate in order to be listed as a recommended hotel for the convention. Although the majority of attendees at the annual meeting typically request a Friday and Saturday two-night package, some attendees may select a Friday night only or a Saturday night only reservation. Customers not attending the convention may also request a Friday and Saturday two-night package, or make a Friday night only or Saturday night only reservation.

A vast majority of Epsilon's customers make reservations through Epsilon's website, but a small percentage of customers make reservations via phone. Epsilon employs call-center personnel to handle these reservations along with any problems with the website reservation system and for the rebooking of flights for customers if their plans change or their travel is disrupted. Staffing the call center appropriately is a challenge for Epsilon's management team. Having too many employees on hand is a waste of money, but having too few results in very poor customer service and the potential loss of customers. Epsilon analysts have estimated the minimum number of call-center employees needed by day of week for the upcoming vacation season (June, July, and the first two weeks of August). These estimates are given in the following table. Day Minimum Number of…arrow_forward
