Part a) julio makes a scale drawing of the kitchen floor to determine how many square feet of flooring he needs to buy . the scale of his drawing is 1 inch: 4 feet. (the length is 4 1/2 and the width is 3 3/8) what is the actual are of julio's kitchen floor? part b) julio makes a scale drawing of part of the kitchen wall to design a tile pattern. he will use gray tiles and white tiles to form the pattern shown. the length of each square in the drawing represents 1/2 foot on the actual kitchen wall. (there are 14 gray tiles and 10 white tiles) if julio uses 2-inch by 2-inch tiles, how many tiles of each color will he need?

1. an economy consists of three workers: larry, moe, and curly. each works 10 hours a day and can produce two services: mowing lawns and washing cars. in an hour, larry can either mow one lawn or wash one car; moe can either mow one lawn or wash two cars; and curly can either mow two lawns or wash one car. a. calculate how much of each service is produced under the following circumstances: a. all three spend all their time mowing lawns. b. all three spend all their time washing cars. c. all three spend half their time on each activity d. larry spends half of his time on each activity, while moe only washes cars and curly only mows lawns b. using your answers to part a, draw a production possibilities frontier and label points a, b, c, and d on your graph. explain why the production possibilities frontier has the shape it does. c. are any of the allocations calculated in part a inefficient? explain.

4. (10.03 mc) the equation of line cd is y = −2x − 2. write an equation of a line parallel to line cd in slope-intercept form that contains point (4, 5). (4 points) y = −2x + 13 y = negative 1 over 2 x + 7 y = negative 1 over 2 x + 3 − 2x − 3
