1. Which of the following is the value below rounded to the nearest thou-
sandth? 34,582.29176
a. 35,000.00000
b. 34,582.29200
c. 34,582.29100
d. 34,582.29000 :::: b. 34,582.29200
2. Half a circle. Diameter = 10 (r=5 for half)
Which of the following is the accurate calculation of the perimeter of the object
above? (use 3.14 for pi)
a. 20.7 cm
b. 41.4 cm
c. 39.3 cm
d. 25.7 cm :::: d. 25.7 cm
This is the calculation of half the circumference of the circle (10 x 3.14/2) added to the
length of the diameter (5 x 2).
,3. The shopper at a local grocery store weighs a bag of apples. the weight is
2.4 pounds (lb).Which of the the following is the weight of the apples? ( NOTE : 1 lb
= 16 oz)
a. 14.4 oz
b. 19.2 oz
c. 28.8 oz
d. 38.4 oz :::: d. 38.4 oz
x/2.4lb = 16oz/1lb
Another way to solve this problem is to multiply 2.4 X 16 ounces.
4. The sum of two numbers is 20. Which of the following equation states that
the product of one number and the square of the other number is 50?
a. x^2(x + 20) = 50
b. x(20 + x)^2 = 50
c. x(x - 20)^2 = 50
d. x^2(20 - x) = 50 :::: d. x^2(20 - x) = 50
Let x equal one number, then 20 - x equals the other number. The phrase "the product
of one number and the square of the other is 50" could be represented by either x2(20
- x) = 50 or x(20 - x)2 = 50.
, 5. A $75 sweater is discounted by $15.Which of the following is the percent of
the discount?
a. 15%
b. 20%
c. 80%
d. 85% :::: b. 20%
To determine the percent of the discount, take the discount amount ($15) and divide
by the original price ($75). This equals 0.2, which is equivalent to 20%.
6. 8 - 12z = 92 solve the equation for z. Which of the following is correct?
a. -81/3
b. 7
c. -7
d. 81/3 :::: c. -7
This is the result of subtracting 8 from both sides of the equation, then dividing the
remaining values by -12. The quotient is negative, because a positive divided by a
negative results in a negative value.
7. A box has a length of 2 1/2 feet, a width of 3 1/3 feet, and a height of 4 1/4
feet.The formula for volume is length X width X height.Which of the following is
