If the ratio of women to men attending a football game is 2 : 3, what percentage of the total attendees are men?

• 30%

• 40%

• 60%

• 66%

Answer explanation

The ratio of women to men is 2:3. This means for every 5 attendees (2 women + 3 men), 3 are men. To find the percentage of men, divide 3 by 5 and multiply by 100, resulting in 60%. Thus, the correct answer is 60%.

Which context can NOT be represented with the numbers 10 and -13?

• Analysse puts $10 in her savings account. The following day, she takes $13 out of her savings account.

• Dawn was at the pool this past summer. Dawn was on the diving block which was 13 feet above the pool surface and when she dove, she reached a depth of 10 meters before coming back up to the surface.

• Recently in Chicago, it was 10 degrees above 0. At night, the temperature fell to 13 degrees below 0.

• The NY Giants lose 13 yards on the first play. On the next play, the Giants gain 10 yards.

Answer explanation

Dawn's context cannot be represented with 10 and -13 because it mixes units (feet and meters) and does not reflect a net change like the other scenarios, which involve consistent numerical representations.

Which value for p makes this equation true? (12 × 52) = (12 × 50) + (12 × p)

• 50

• 2

• 12

• 52

Answer explanation

To solve for p, simplify the equation: (12 × 52) = (12 × 50) + (12 × p). This gives 624 = 600 + 12p. Subtract 600 from both sides: 24 = 12p. Dividing by 12, we find p = 2, which is the correct answer.

At a party, every person either ate cake or a cookie. 40% of attendees ate cake, and 15 people ate cookies. How many people were at the party in total?

• 25 people

• 30 people

• 20 people

• 35 people

Answer explanation

Let total attendees be x. 40% ate cake, so 0.4x ate cake. Since 15 ate cookies, we have 0.4x + 15 = x. Solving gives x = 25. Thus, there were 25 people at the party.

On a coordinate graph, points A (2, 5), B (-1, 5), C (-1, -2) and D (2, -2) are vertices of a rectangle. What is the area of the rectangle?

• 20 square units

• 21 square units

• 14 square units

• 13 square units

Answer explanation

To find the area of rectangle ABCD, calculate the length and width. The length (horizontal distance) is |2 - (-1)| = 3 units, and the width (vertical distance) is |5 - (-2)| = 7 units. Area = length × width = 3 × 7 = 21 square units.
