Your answers are highlighted below. Question 1A shopping center counts the number of shoppers it has every day. On Wednesday it had 4,103 shoppers. On Thursday it had 1,626 shoppers, on Friday it had 6,123 shoppers, and on Saturday it had 7,398 shoppers. Which number below represents the best estimate of the total amount of shoppers at the mall for these four days?
Question 1 Explanation:The correct answer is D.
Round the amount of shoppers for each day to the nearest five hundred.
4,103 is rounded to 4,000
1,626 is rounded to 1,500
6,123 is rounded to 6,000
7,398 is rounded to 7,500
Then add: 4,000 + 1,500 + 6,000 + 7,500 = 19,000
Terri is going to clean her house. She uses 2 buckets of water in each room downstairs, and there are 7 rooms downstairs. She uses 3 buckets of water in each room upstairs, and there are 5 rooms upstairs. How many buckets of water will she need in total?
Question 2 Explanation:The correct answer is C.
Find the total for downstairs: 2 buckets per room × 7 rooms = 14 buckets of water for downstairs
Then find the total for upstairs: 3 buckets per room × 5 rooms = 15 buckets of water for upstairs
Finally, add the two together to get the total: 14 + 15 = 29
Pedro has a large vegetable garden in his back yard. He needs to apply 6 quarts of fertilizer every four days. Approximately how much fertilizer will he need per month?
Question 3 Explanation:The correct answer is A.
Find the rate per day first: 6 quarts ÷ 4 days = 1.5 quarts per day
Then multiply by 30 days to get the answer: 1.5 quarts × 30 days = 45 quarts
Ahmed is trying to figure out how much food he needs for his birthday party. He knows that each of his guests will eat 3 slices of pizza. If each pizza has 8 slices and there are going to be 14 people at the party including Ahmed, how many pizzas will he need?
Question 4 Explanation:The correct answer is C.
Determine the amount of slices he needs in total:
14 people × 3 slices per person = 42 slices needed
Then divide by the amount of slices per pizza to determine the amount of pizzas he needs:
42 slices needed ÷ 8 slices per pizza = 5.25 pizzas needed
It is not possible to buy part of a pizza, so we have to round up to 6 pizzas.
The correct answer is B.
When converting a fraction to a decimal, you can treat the line in the fraction as the division symbol:
75 /450 = 75 ÷ 450
Then do the division: 75 ÷ 450 = 75 ÷ 450.000 = 0.166
The ratio of A's to B's for the graduating class was 6 to 7. If the total number of students in the class who got A's or B's was 117, how many students got A's?
Question 6 Explanation:The correct answer is B.
For your first step, add the subsets of the ratio together:
6 + 7 = 13
Then divide this into the total:
117 ÷ 13 = 9
Finally, multiply the result from the previous step by the subset of A's from the ratio:
6 × 9 = 54 A's in the graduating class
An employee receives the following performance review scores: 89, 65, 75, 68, 82, 74, 86. What is the mean of his scores?
Question 7 Explanation:The correct answer is D.
To find the mean, add up all of the items in the set and then divide by the number of items in the set.
There are 7 numbers in the set, so perform the calculation as follows:
(89 + 65 + 75 + 68 + 82 + 74 + 86) ÷ 7 =
539 ÷ 7 = 77
The correct answer is D.
When you see the absolute value signs, we need to make the number inside the signs positive.
For example: | –15| = 15
Substitute the values for x and y to solve.
| xy | =
| –10 × 14 | =
| –140 | =
140
The answer correct is B.
Remove the parentheses and group like terms together. Then perform the operations to solve.
(3a 2 + 4ab + 2b 2 ) + (7a 2 – ab – 6b 2 ) + (8a 2 – 5ab – 4b 2 ) =
3a 2 + 4ab + 2b 2 + 7a 2 – ab – 6b 2 + 8a 2 – 5ab – 4b 2 =
3a 2 + 7a 2 + 4ab + 2b 2 + 7a 2 – ab – 6b 2 + 8a 2 – 5ab – 4b 2 =
3a 2 + 7a 2 + 4ab + 2b 2 – ab – 6b 2 + 8a 2 – 5ab – 4b 2 =
3a 2 + 7a 2 + 8a 2 + 4ab + 2b 2 – ab – 6b 2 + 8a 2 – 5ab – 4b 2 =
3a 2 + 7a 2 + 8a 2 + 4ab + 2b 2 – ab – 6b 2 – 5ab – 4b 2 =
3a 2 + 7a 2 + 8a 2 + 4ab – ab + 2b 2 – ab – 6b 2 – 5ab – 4b 2 =
3a 2 + 7a 2 + 8a 2 + 4ab – ab + 2b 2 – 6b 2 – 5ab – 4b 2 =
3a 2 + 7a 2 + 8a 2 + 4ab – ab – 5ab + 2b 2 – 6b 2 – 5ab – 4b 2 =
3a 2 + 7a 2 + 8a 2 + 4ab – ab – 5ab + 2b 2 – 6b 2 – 4b 2 =
(3a 2 + 7a 2 + 8a 2 ) + (4ab – ab – 5ab) + (2b 2 – 6b 2 – 4b 2 ) =
18a 2 – 2ab – 8b 2
Question 10 If 5(x – 1) = 20, then x = ? Question 10 Explanation:The correct answer is A.
Expand the equation:
5(x – 1) = 20
(5 × x) + (5 × –1) = 20
5x – 5 = 20
Deal with the integer.
5x – 5 + 5 = 20 + 5
5x = 25
Divide by the coefficient to solve.
5x ÷ 5 = 25 ÷ 5
x = 5

9) Determine the midpoint of the line that connects (−6, 3) and (2, −7).
10) The perimeter of a rectangle is 64 meters. If the width were increased by 2 meters and the length were increased by 3 meters, what is the perimeter of the new rectangle?
Here is an example of the kinds of solutions we provide with our college math placement test download.
The answer is: 2.498
You will be able to use scratch paper on the test. When you are working out the solution, you have to align the decimals by adding zeros where necessary like this:
The answer is: 29.484
Remember to position the decimal correctly after performing the multiplication.
The decimal is placed three numbers from the right hand side of the result because 7.02 has 2 decimal places and 4.2 has got only 1 decimal place.
So you simply have to add these together to determine where to put the decimal in the final product.
The multiplication is done as follows:
The answer is: 1/3
The total amount of time that all of the potential volunteers are going to work will be equal to 100%. We can simplify 100% to 1 for purposes of making an equation to solve the practice problem.
In order to make the equation, we will assign S to Shannon and T to Terry. The work to be done by the other volunteers will be represented letter V.
Therefore, the equation needed to solve the problem is:
Now substitute with the fractions that have been provided:
Then find the lowest common denominator (LCD) of the fractions.
1/2 is equal to 3/6 (1/2 × 3/3 = 3/6), so the LCD is 6.
Now substitute 3/6 for 1/2 in the equation:
Then simplify this as follows: 2/6 ÷ 2/2 = 1/3
The answer is: 4
First of all, you need to multiply the items in the parentheses:
Next, isolate the integers to one side of the equation:
6x − 3x − 12 + 12 = 0 + 12
Then solve for x:
You will often see algebraic expressions in this format on the exam:
These kinds of algebra problems are called binomials – “bi” since they have two terms inside each of the pairs of parentheses.
First, expand the equation like this:
Then you have to multiply the terms from each of the pairs of parentheses in the following order:
FIRST: Take the first term from each set of parentheses and multiply them to get a product.
OUTSIDE: Now look at the first set of parentheses and take the first term from there, and then look at the second set of parentheses and take the last term form there.
In other words, these terms are positioned on the outer edge of each set of parentheses so they are on the outside.
INSIDE: Now find the product of the second term from the first pair of parentheses and the first term from the second pair of parentheses.
This is called the inside because the terms are situated together at the inner part of the equation.
LAST: Now you need to multiply the final or last terms in each of the pairs of parentheses.
TO SOLVE: Then we add all of the above parts together to get:
The First-Outside-Inside-Last method of multiplying binomials is sometimes referred to with the acronym “FOIL”.
You will see several “FOIL” method questions on the test, so we are giving you another chance to practice “FOIL” below.
Then add the four above products together like this to get the answer to this test question:
This practice test item covers exponent laws.
In order to solve these problems, you need to determine whether the base numbers in each part of the equation are the same. 8 is the base number in this equation.
Since the base numbers are the same, we need to subtract the exponents and leave the base number unchanged.
Remember that if you see multiplication of exponents, you need to add the exponents.
The answer is: 120 permutations
To determine the amount of permutations of size S that can be derived from a set of N items, you need the permutations formula:
In this question N = 6 since there are six items in the letter set Q R W X Y Z.
S = 3 because the problems is asking you to find three-letter permutations.
The exclamation point means that you have to multiply the number by every integer that precedes it.
(6 × 5 × 4 × 3 × 2 × 1) ÷ (6 − 3) =
(6 × 5 × 4 × 3 × 2) ÷ (3 × 2 × 1)=
Remember that the formula for permutations is distinct from the formula for combinations.
Permutations consider the order of the items in each set, but combinations do not.
So, A B C and B C A are different permutations.
However, A B C and B C A are the same combination.
The answer is: (−2, −2)
The midpoint formula is (x1 + x2) ÷ 2 , (y1 + y2) ÷ 2
Note that x1 means the value of x from the first set of coordinates, while x2 represents the value of x from the second set of coordinates.
The line connects (−6, 3) and (2, −7).
Now use the formula above to determine midpoint x:
Then use the other part of the midpoint formula to determine midpoint y:
The answer is: (−2, −2)
The answer is 74 meters.
Step 1 – Set up equations for the areas of the rectangles both before and after the change.
Express the width as the variable W and the length as variable L.
Remember that perimeter is calculated as two times the width plus two times the length, so the formula for perimeter is 2W + 2L = P
So the equation we need before the change is:
Step 2 – Isolate variable W to one side of the equation:
2L − 2L + 2W = 64 − 2L
2W ÷ 2 = (64 − 2L) ÷ 2
Step 3 – Then set up the equation that will calculate the perimeter of the rectangle after the changes to its dimensions.
P = 2(L + 3) + 2(W + 2)
We add 3 to the length and 2 to the width because width is increased by 2 meters and length is increased by 3 meters, according to the facts in the question provided.
Step 4 – Now substitute 32 − L from the W = 32 − L from the “before” equation above into the W in the equation below to arrive at the final solution:
P = 2(L + 3) + 2(W + 2)
P = 2(L + 3) + 2(32 − L + 2)
P = (2L + 6) + 2(34 − L)
P = 2L + 6 + 68 − 2L
