Magic Realm, Inc., has developed a new fantasy board game. The company sold 15,000 games last year at a selling price of $20 per game. Fixed expenses associated with the game total$182,000 per year, and variable expenses are $6 per game. Production of the game is entrusted to a printing contractor. Variable expenses consist mostly of payments to this contractor. 1. Prepare a contribution format income statement for the game last year and compute the degree of operating leverage. 2. Management is confident that the company can sell 18,000 games next year (an increase of 3,000 games, or 20%, over last year). Compute: a. The expected percentage increase in net operating income for next year. b. The expected total dollar net operating income for next year. (Do not prepare an income statement; use the degree of operating leverage to compute your answer.)

"England's green and pleasant land" tempted invaders and conquerors-first the Celts, then Romans, Saxons, Danes, and Normans. Why would the question of succession to the throne have been of paramount importance to the people who first heard these tales recited?

(a) How many significant figures are in the numbers 99 and 100.? (b) If the uncertainty in each number is 1, what is the percent uncertainty in each? (c) Which is a more meaningful way to express accuracy of these two numbers: significant figures or percent uncertainties?

How many significant figures do the following number has: $214$?

Draw a pair of similar figures with areas that have a ratio of $4: 1$. Explain.

In this activity, you will use what you know about dilations to determine if figures are similar.

1. Determine if the figures are similar. If they are similar, state the scale factor and the center of dilation that maps Figure 1 onto Figure 2.

How does the use of population figures strengthen the case Las Casas is presenting?

The height of a computer screen is 31.25 cm, and its width is 47 cm. (a) Is the area of the screen known to one, two, three, or four significant figures? (b) Calculate the area of the screen, giving your answer with the correct number of significant figures.

Isoperimetric problem The isoperimetric problem is to prove that of all plane geometric figures with the same perimeter (isoperimetric figures), the circle has the greatest area. Show that no rectangle has both the same area and the same perimeter as any circle.

How many significant figures are shown in number 902.10? If this is intermediate, explain why.

How many significant figures are shown in number 0.02173? If this is intermediate, explain why.
