Area = (1/2) × base × height = (1/2) × 6 × 8 = 24.
Question 30
If x^2 = 81, what is the positive value of x?
The positive square root of 81 is 9 because 9 × 9 = 81; the negative root is -9.
Question 31

With an even count, the median is the average of the two middle values: (5 + 9) / 2 = 7.
Question 38
If 5x = 45, what is x?
Divide both sides by 5 to isolate x: 5x = 45 becomes x = 45 / 5 = 9.
Question 39

Use the formula distance = rate × time: 60 miles per hour × 2.5 hours = 150 miles.
Question 47
Which quantity is greater: 0.4 or 1/3?
1/3 ≈ 0.333, which is less than 0.4.
Question 48
Which integer between 20 and 30 is divisible by both 3 and 4?
24 is divisible by 3 and by 4; the other choices are not.
Question 49
What is 3/5 + 1/10?
3/5 = 6/10, and 6/10 + 1/10 = 7/10.
Question 50
What is the probability of rolling a 6 on a fair six-sided die?
One favorable outcome out of six equally likely outcomes gives 1/6.
Question 51
12 is what percent of 48?
Divide the part by the total: 12 / 48 = 0.25, and multiplying by 100 gives 25%.
Question 52
If 2x - 6 = 10, what is x?
Add 6 to both sides to get 2x = 16, then divide by 2 to find x = 8.
Question 53
What is the circumference of a circle with radius 5?
The circumference of a circle is 2π times the radius: 2π × 5 = 10π.
Question 54
What is the slope of the line through (0, 0) and (4, 8)?
Slope is the change in y divided by the change in x: (8 - 0) / (4 - 0) = 2.
Question 55
What is the sum of 7 and 13 divided by 5?
Add the numbers in the numerator first: (7 + 13) / 5 = 20 / 5 = 4.
Question 56
What is 40% of 250?
Convert 40% to 0.40 and multiply: 250 × 0.40 = 100.
Question 57
If n is an odd integer, which of the following must be even?
Adding 1 to an odd integer always produces an even integer.
Question 58
What is the greatest common factor of 18 and 24?
The largest factor shared by 18 and 24 is 6.
Question 59
What is 0.125 written as a fraction?

5 + 5, 20 / 2, and 2 × 5 all equal 10.
Question 64
Which of the following are multiples of 6?
12, 18, and 24 are all multiples of 6, so each one is divisible by 6 without a remainder.
Question 65
Which words mean a small amount or supply?
Scarce, sparse, and meager all describe a small amount, so they are similar in meaning even if the context differs.
Question 66
Which words are closest in meaning to "zeal"?
Zeal means great energy or enthusiasm, so enthusiasm and passion fit.
Question 67
Which descriptions suggest a positive correlation in a scatterplot?
Positive correlation means values increase together, shown by an upward trend.
Question 68
Which expressions are equivalent to 2(x + 3)?
Distributing gives 2x + 6, and multiplication is commutative, so (x + 3) × 2 is also equivalent.
Question 69
Type the value of x if 3x = 27.
Divide both sides by 3 to isolate x: 3x = 27 becomes x = 27 / 3 = 9.
Question 70
Type the mean of 5, 10, and 15.
The mean is the sum divided by the count: (5 + 10 + 15) / 3 = 30 / 3 = 10.
Question 71
Type 2/5 as a decimal.
Multiply the numerator and denominator by 2 to get 4/10, which equals the decimal 0.4.
Question 72
Type the area of a square with side length 6.
The area of a square is side squared: Area = 6 × 6 = 36 square units.
Question 73
Type the next term in the sequence 3, 6, 12, 24.
The pattern multiplies each term by 2: 6, 12, 24, so the next term is 24 × 2 = 48.
Question 74
Type the slope of the line y = 4x - 2.
In the slope-intercept form y = mx + b, the coefficient m is the slope, so m = 4 here.
