The water level in a rectangular swimming pool measuring 50 feet by 25 feet is to be lowered by 6 inches. How many gallons of water must be removed? (1 cu ft = 7.5 gallons)
[ "250", "4687.5", "750", "100" ]
B
6 inches = 1/2 feet (there are 12 inches in a foot.), so 50*25*1/2=625 feet^3 of water must be removed, which equals to 625*7.5=4687.5 gallons. Answer: E.

For an employee to qualify for early retirement at a certain company, the sum of the employee’s age and years of service must be at least 76, If Sue was K years old when she was hired by the company, what is the minimum age at which she could possibly qualify for early retirement?
[ "(76-K)/2", "K+38", "2K+38", "(76+K)/2" ]
D
Let y be the years of service at the company. After y years of service, Sue's age will be K + y. Sue can retire when (K+y) + y = 76 y = (76 - K)/2 Then Sue's age will be K + y = K + (76 - K)/2 = (76+K) / 2 The answer is C.

[ "4 - pi", "2pi - 4", "pi^2 - 2", "2 - pi/4" ]
B
Drawing a diagram, we see that the radius of the circle equals the side of the square. The area of intersection is: pi*r^2/4 - (r^2-pi*r^2/4) = pi*r^2/2 - r^2 = 2pi - 4 The answer is B.
