A wall is 7 feet 8 inches in height; four vertical pieces of wallpaper are needed to cover the wall.Assuming there is no waste, what is the minimum length that a roll of wallpaper must be to cover the wall?
Answer(s): D
If there are four pieces of wallpaper, each 7 feet, 8 inches long, the total length of the wallpaper is 4 × 7 feet, 8 inches, or 28 feet, 32 inches. Since 12 inches = 1 foot, 32 inches = 2 feet, 8 inches. Thus, 28 feet, 32 inches = 30 feet, 8 inches.
We bought 5 pounds of cashew nuts worth $1.80 per pound, mixed with 4 pounds of peanuts worth $1.62 per pound.What is the value per pound of the mixture?
Answer(s): A
5 pounds of cashew nuts at $1.80 per pound is worth 5 × $1.80 = $9.00 4 pounds of peanuts at $1.62 per pound is worth 4 × $1.62 = $6.48.The total value of the 9-pound mixture is $9.00 + $6.48 = $15.48. The value of the mixture per pound is found by dividing the total value by the number of pounds.$15.48 / 9 = $1.72
In a clothing factory, 5 workers finish production of 6 garments each per day, 3 others turn out 4 garments each per day, and 1 worker turns out 12 per day.What is the average number of garments produced per worker per day?
Answer(s): B
5 workers making 6 garments each = 30 garments per day3 workers making 4 garments each = 12 garments per day1/9 workers making 12 garments = 12/54 garments per dayAdd the number of workers and the number of garments per day.9 workers make 54 garments per day.To find the average number of garments per worker per day, divide the number of garments per day by the number of workers.54/9 = 6 garments per worker per day.
A man makes a 255-mile trip by car. He drives the first 2 hours at 45 miles per hour.At what speed must he then travel for the remainder of the trip in order to arrive at his destination 5 hours after he started?
The distance traveled by driving at 45 mph for 2 hours is 2 × 45, or 90 miles.The remainder of the 255 mile trip is 255 - 90, or 165 miles.To finish the trip in 5 hours, the man has 5 - 2, or 3, hours still to drive.To find the rate of travel for a distance of 165 miles driven in 3 hours, divide the distance by the time.165/3 = 55 miles per hour
