|
200 lbs per sq ft |
1) 200 x 200 = 40000 2) 4000 tons x 2000 lbs = 8000000 3) 8000000/40000 = 200

In order to check on a shipment of 500 articles, a sampling of 50 articles was carefully inspected. Of the sample, 4 articles were found to be defective. On this basis, what is the probable percentage of defective articles in the original shipment? |
8% |
The sample size is 50. Four defects were found in the sample. The number of defective articles divided by the sample size (4/50) tells us how much of the sample was defective (0.08, or 8%). If 8% of the sample was defective, it is probable that the percentage of defective articles in the complete original shipment is also 8%. |

Two office workers have been assigned to address 750 envelopes. One addresses twice as many envelopes per hour as the other. If it takes five hours for them to complete the job, what was the rate of the slower worker? |
50 envelopes per hour |
Let x equal the number of envelopes addressed in 1 hour by the slower worker, and let 2x equal the number of envelopes addressed in 1 hour by the faster worker. Together, they address 3x envelopes in an hour. (3x)(5) = 750 15x = 750 x=50

A room measuring 15 feet wide, 25 feet long, and 12 feet high is scheduled to be painted shortly. If there are two windows in the room, each 7 feet by 5 feet, and a glass door, 6 feet by 4 feet, then the area of wall space to be painted measures: |
866 sq ft |
First, let's find the area of one of the long walls: 25 ft. × 12 ft. = 300 sq. ft. Since there are two long walls, the total area of the long walls is 300 × 2 = 600 sq. ft. |

A pound of margarine contains four equal sticks of margarine. The wrapper of each stick has markings that indicate how to divide the stick into eight sections, each section measuring one tablespoon. If a recipe calls for four tablespoons of margarine, the amount to use is: |
1/8 lbs |
Each stick of margarine is 1/4 lb. Each stick consists of eight sections or tablespoons. Four sections or tablespoons are (1/2)(1/4) = 1/8 lbs |
|
|
The price of a $100 item after successive discounts of 10% and 15% is:
|
$76.50 |
$100 × 0.10 = $10.00, and $100 – $10 = $90, the price after the initial 10% discount. Then: $90 × 0.15 = $13.50, and $90.00 – $13.50 = $76.50, the price after the additional 15% discount. |

|
A certain governmental agency had a budget last year of $1,100,500. Its budget this year was 7% higher than that of last year. The budget for next year is 8% higher than this year's budget. Which of the following is the agency's approximate budget next year? |
$1,271,738 |
$1,100,500 × 0.07 = $77,035, and $1,100,500 + $77,035 = $1,177,535, this year's budget. For next year: $1,177,535 × 0.08 = $94,203, and $1,177,535 + $94,203 = $1,271,738 |

If the weight of water is 62.4 pounds per cubic foot, the weight of the water that fills a rectangular container 6 inches by 6 inches by 1 foot is: |
15.6 lbs |
1/2 foot × 1/2 foot × 1 foot = 1/4 cubic foot
***note: all dimensions must be in the same unit. 6 inch = 1/2 of 12 inches (1 ft)*** |
|
|
If there are red, green, and yellow marbles in a jar and 20% of these marbles are either red or green, what are the chances of blindly picking a yellow marble out of the jar? |
4 out of 5 |
If 20% are either red or green, 80% are yellow. The chance of blindly picking a yellow marble is 4 out of 5 (80%). |

When 550 gallons of oil are added to an oil tank that is 1/8 full, the tank becomes 1/2 full. The capacity of the oil tank is most nearly:
|
1470 gals |
(1/8x) + 550 = (1/2x) 550 = (x/2) - (x/8) 550 = (3/8)x x = 550 (8/3) x = 1467 |
|
|
If an aircraft is traveling at 630 miles per hour, how many miles does it cover in 1200 seconds?
|
210 miles |
1200 sec / 60 sec = 20 mins 20 mins / 60 sec = 1/3 630 x (1/3) = 210 miles
***must remember to change everything to the right unit***

If your watch gains 20 minutes per day and you set it to the correct time at 7:00 a.m., the correct time when the watch indicates 1:00 p.m. is:
|
12:55 pm |
The interval between 7:00 a.m. and 1:00 p.m. is 6 hours, or 1/4 of a day, and 1/4 of 20 minutes equals 5 minutes. Subtracting 5 minutes from a watch reading of 1:00 p.m. equals 12:55 p.m. |
|
|
It takes a runner 9 seconds to run a distance of 132 feet. What is the runner's speed in miles per hour? (5280 feet equal 1 mile) |
10 |
The distance is (132/5280) = 1/40. The hours is (9/3600) = 1/400. Traveling 1/40 mile in 1/400 hour, the runner moves 1 mile in 1/10 hour, or 10 miles in 1 hour, or 10 miles per hour. |
|
|
About how many meters will a point on the rim of a wheel travel if the wheel makes 35 rotations and its radius is one meter?
|
220 |
The circumference is multiplied by the number of rotations to get the distance traveled. |
|
|

9 |
A natural number that has no other factors except 1 and itself is a prime number. Nine is divisible by 1, 3, and 9. |
|
|

|
The sum of the angle measures of a pentagon is:
|
540 |
(number of sides – 2) × 180 = sum of angles. So: |
|
|

The volume of a cylinder with a radius of r and a height of h is:
|
(πr^2)h |
|

|
The cube root of 729 is equal to the square of: |
3 |
The cube root of 729 is 9 (because 93 = 9 x 9 x 9 = 729). In turn, 9 is the square of 3 (because 32 = 3 × 3 = 9). |
