Best ResponseYou've already chosen the best response.0Kelly was building a bed for her dollhouse. She used her bed, which is 4 feet × 6 feet, as a guide. She scaled down the dimensions of her bed by a factor 1 over 5. What are the dimensions of the model bed she built? 0.8 foot × 1.2 feet 0.4 foot × 0.6 foot 0.08 foot × 0.12 foot 0.04 foot × 0.06 foot

Best ResponseYou've already chosen the best response.1hint: you have to multiply the dimensions of the bed of Kelly by a factor 1/5= 0.2

Best ResponseYou've already chosen the best response.0The seventhgrade class is building target areas for a PE activity. The bases for the game will be circular in shape. The diameter of each circle is 5 feet. Approximately how many square feet of the turf need to be painted for a base circle? Use 3.14 for π and round your answer to the nearest tenth. 15.7 square feet 19.6 square feet 42.8 square feet 78.6 square feet

Best ResponseYou've already chosen the best response.0Im thinking it's 6ft∗π it's 9.4 6ft*pi/2=9.42=9.4 @Astrophysics

Best ResponseYou've already chosen the best response.1Where is the 6ft coming from? Do you really think that is true, check your answer choices, it's not even an option

Best ResponseYou've already chosen the best response.1You're just looking for the area of a circle \[A = \pi r^2\] where r is the radius, which is half the diameter.
