During the summer, Kurt works on his uncle's goat farm. One of Kurt's many chores is to milk the goats. The proportional relationship between the number of hours milking, x, and the number of goats milked by Kurt, y, can be modeled by the equation y = 6x. If Kurt milked 21 goats, how many hours did it take? A) 3 B) 3.5 C) 4 D) 4.5 2) The ratio of boys to girls in the Science Club is 3:5. If there are 60 girls, how many boys are there? A) 23 B) 36 C) 38 D) 45 3) A house on a floor plan is 10.5 inches long and 6.5 inches wide. If the scale used is 0.5 inch = 2 ft, how long is the actual house? A) 13 ft B) 21 ft C) 26 ft D) 42 ft 4) What is the multiplicative inverse of −18? A) − 1 18 B) 1 18 C) 17 18 D) 18 5) Evaluate the expression. 7 + 2 × [3 × (3 + 2)2] A) 112 B) 157 C) 375 D) 675 6) A building's basement is 12 feet below ground. If the total length of the building from basement to roof is 62 feet, what is the building's elevation above ground? A) 38 feet B) 50 feet C) 62 feet D) 74 feet 7) Write an equation that gives the proportional relationship of the graph. A) y = 1 6 x B) y = 6x C) y = 7x D) y = 42x 8) A wedding cake has a diameter of 12 inches. The cake decorator needs to know how many strawberries he will need to put around the outside, so he needs the circumference. What is the circumference? Leave the answer in terms of π.
