Find the angle labeled X in the diagram:
A.
50
B.
82
C.
98
D.
102
Correct Answer B. 82
Explanation The angle labeled X can be found by subtracting the given angles from 180 degrees, since the sum of the angles in a triangle is always 180 degrees. Subtracting 50, 98, and 102 from 180 gives us 82, which is the measure of angle X.

Amelia buys a crate of 30 eggs for $20. If she sells each egg for 75 cents, state whether she made a profit or a loss and calculate the percentage (profit or loss).
Correct Answer Profit 12.5 %, profit 12.5%, Amelia made a profit of 12.5%, She made a profit of 12.5%, Profit = 12.5%
Explanation Amelia made a profit of 12.5% because the selling price of each egg is greater than the cost price. To calculate the percentage profit, we can use the formula: (Profit/Cost Price) * 100. In this case, the profit is $20 * 12.5% = $2.50. So, the percentage profit is ($2.50/$20) * 100 = 12.5%.

A man buys a car for $40,000.00. Every year the value of the car depreciates by 10%. What is the car worth after 3 years?
Explanation The car depreciates by 10% every year, which means its value decreases by 10% each year. After the first year, the car is worth 90% of its original value, which is $40,000.00 * 0.9 = $36,000.00. After the second year, the car is worth 90% of its second-year value, which is $36,000.00 * 0.9 = $32,400.00. After the third year, the car is worth 90% of its third-year value, which is $32,400.00 * 0.9 = $29,160.00. Therefore, the car is worth $29,160.00 after 3 years.

The Venn diagram below shows sets A and B, where A represents the set of items in Andy's schoolbag and B represents the set of items in Melissa's schoolbag. Find A n B (A intersect B)
Correct Answer {pencil, blue ink pen, reading book, math book, copy book}, pencil, blue ink pen, reading book, math book, copy book, pencil blue ink pen reading book math book copy book
Explanation The correct answer is {pencil, blue ink pen, reading book, math book, copy book}. This is because the intersection of sets A and B represents the items that are common to both Andy's and Melissa's schoolbags. In this case, all the items listed are present in both sets A and B, so the intersection is equal to the original sets.

Correct Answer B. {color pencils, black ink pen, toy car, crayons, markers, red ink pen, coloring book, pencil, blue ink pen, reading book, math book, copy book}
Explanation The correct answer {color pencils, black ink pen, toy car, crayons, markers, red ink pen, coloring book, pencil, blue ink pen, reading book, math book, copy book} represents A U B because it includes all the elements from both set A and set B. Set A includes {color pencils, black ink pen, toy car, crayons, markers, red ink pen, coloring book} and set B includes {pencil, blue ink pen, reading book, math book, copy book}. The union of set A and set B will include all the elements from both sets, resulting in the given answer.

35/700 expressed as a percentage is:
A.
50%
B.
0.5%
C.
5 %
D.
0.05%
Correct Answer C. 5 %

13501 + 2793 equals
A.
15293
B.
15294
C.
16293
D.
16294
Correct Answer D. 16294
Explanation To find the sum of 13501 and 2793, we add the corresponding digits from right to left. Starting from the rightmost column, 1 plus 3 equals 4. Moving to the next column, 0 plus 9 equals 9. Continuing this process, we have 5 plus 7 equals 12. Therefore, we write down 2 and carry over the 1. Finally, in the leftmost column, we have 1 plus 2 plus 2 equals 5. Thus, the correct sum is 16294.

2 x (5 - 1) + 3 - 1 / 5 =
A.
2 3/5
B.
2
C.
10 4/5
D.
9
Correct Answer B. 2
Explanation To solve this expression, we follow the order of operations (PEMDAS/BODMAS), which stands for Parentheses/Brackets, Exponents/Orders, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right).
First, we simplify inside the parentheses:
5 - 1 = 4
Then, we apply multiplication and subtraction within the parentheses:
2 * 4 = 8
Next, we simplify the subtraction outside the parentheses:
8 + 3 - 1 = 10
Now, we perform division:
10 / 5 = 2
Therefore, the value of the expression is 2.

1.35 x 2.1 =
A.
2.385
B.
3.35
C.
2.35
D.
2.835
Correct Answer D. 2.835
Explanation The correct answer is obtained by multiplying 1.35 by 2.1. This can be done by multiplying the digits individually and then adding the decimal places. Multiplying 5 by 1 gives 5, and multiplying 5 by 2 gives 10. Adding the decimal places gives 1.0. Multiplying 3 by 1 gives 3, and multiplying 3 by 2 gives 6. Adding the decimal places gives 0.6. Adding the two results together gives 5.6. Therefore, the correct answer is 2.835.
