Which of the following is the percentage equivalent of 0.0016?
A. 16% B. 160% C. 1.6%
0.0016(100) = 0.16%
Curtis is taking a road trip through Germany, where all distance signs are in metric. He passes a sign that states the city of Dusseldorf is 45 kilometers away. Approximately how far is this in miles?
A. 42 miles
B. 37 miles C. 28 miles
45(0.62) = 27.9 approximately 28 miles
On a floor plan drawn at a scale of 1:100, the area of a rectangular room is 30 cm2. What is the actual area of the room?
A. 30,000 cm2
B. 300 m2
C. 3,000 m2
each centimeter represents one meter. Therefore, an area of one square centimeter on the drawing represents one square meter tin actuality.
- Since the area of the room in the scale drawing is 30 cm2, the room's actual area is 30 m2.
L/100 x W/100 = 30 cm2 lw/100 = 30 cm2
Area = 300,000 cm2
D. 0.16% {
ANS} - D. To derive a percentage from a decimal, multiply by 100:
D. 16 miles {
ANS} - C. one kilometer is about 0.62 miles,
D. 30 m2
{ANS} - D. Since there are 100 cm in a meter, on a 1:100 scale drawing,
300,000 cm2 x. 1m/100 cm x 1m/100 cm = 30m2
Mandy can buy 4 containers of yogurt and 3 boxes of crackers for $9.55. She can buy 2 containers of yogurt and 2 boxes of crackers for $5.90. How much does one box of crackers cost?
A. $1.75
B. $2.00 C. $2.25
The situation may be modeled by the system: 4x + 3y = 9.55
2x + 2y = 5.90
Multiplying the bottom equation by - 2 gives:
4x + 3y = 9.55 -4x - 4y = -11.80
Addition of the two equations gives - y = -2.25 or y = 2.25. Thus, one box of crackers costs $2.25
9.55-11.80 = -2.25 -y = -2.25
-y/-1 = -2.25/-1
y = 2.25
1. THE NEXT TWO QUESTIONS ARE BASED ON THE FOLLOWING INFORMATION:
Pernell's scores on her last five chemistry exams were 81, 92, 87, 89, and 94.
What is the approximate average of her scores? A. 81
B. 84
C. 89
D. $2.50
{ANS} - C.
D. 91 {
ANS} - C. To find the average of Pernell's scores, add them up and then
divide by the number of scores (5 in this case). In other words,
81 + 92 + 87 + 89 + 94 = 443 443/5 = 89
2. THE NEXT QUESTIONS ARE BASED ON THE FOLLOWING INFORMATION: Pernell's scores on her last five chemistry exams were 81, 92, 87, 89, and 94.
What is the medium of Pernell's scores? A. 87
B. 89
C. 92
The middle number represents the median -- in this case 81, 87, 89, 92, 94. The number 89 is in the middle, so it is the median.
Gordon purchased a television when his local electronics store had a sale. The television was offered at 30% off its original price of $472. What was the sale price that Gordon paid?
A. $141.60
B. $225.70 C. $305.30
is 141.60. (0.30)(472) = 141.60
472 - 141.60 = 330.40
Thus, Gordon paid $330.40 for the television.
