Math Trivia

To find the time taken, divide the distance by the speed: Time = Distance / Speed Time = 320 miles / 80 miles per hour Time = 4 hours

"Like fractions" are fractions that have the same denominator. In the context of the given options:   10.5 and 12: These are not fractions; they are decimal numbers.   1.8 and 4: These are not like fractions because they have different denominators.   1/100 and 9/4: These are not like fractions because they have different denominators.   2/3 and 1/3: These are like fractions because they share the same denominator, which is 3. The fractions 2/3 and 1/3 are like fractions because they represent parts of a whole divided into three equal parts.

Negative numbers are all less than zero. Zero is not a negative number, but it is less than any positive number. Therefore, zero is the correct answer as it is the only option that is not a negative number.

A mixed number is a combination of a whole number and a fraction. It is written in the form of a whole number followed by a fraction, such as 3 1/2. The whole number represents the number of whole units, while the fraction represents the part of a whole unit. Therefore, the correct answer is "A Whole Number And A Fraction."

The equation 3 x 3 = 9 represents multiplication, where the number 3 is being multiplied by itself. The product is the result of the multiplication, which in this case is 9.

An octagon is a polygon with eight sides. It is a shape that has eight straight sides of equal length. Therefore, the correct answer to the question "Which polygon has eight sides?" is octagon.

The kilometer is the largest unit of measurement among the options given. It is larger than a meter, decimeter, and centimeter. The kilometer is a unit used to measure longer distances, while meter, decimeter, and centimeter are used for shorter distances. Therefore, the kilometer is the correct answer as it represents the largest unit of measurement in this context.

Meter is a measure used for distance. It is a unit of length in the metric system and is commonly used to measure the distance between two points. It is a fundamental unit of measurement and is widely used in various fields such as engineering, physics, and everyday life.

If an item costs $1.29 and you pay with two $1 bills, you would get $0.71 in change. To calculate this, subtract the cost of the item ($1.29) from the amount you paid ($2.00). The difference is $0.71, which is the correct answer.

The correct answer is 180 Watts because if a lamp uses three 60-watt bulbs, the total power required is calculated by multiplying the wattage of each bulb by the number of bulbs. Therefore, 60 watts multiplied by 3 bulbs equals 180 watts.

To earn $3.50 by selling cups of lemonade at $0.25 each, you need to divide the total earnings by the price per cup. In this case, $3.50 divided by $0.25 equals 14 cups. Therefore, you must sell 14 cups of lemonade to earn $3.50.

The formula a^2 + b^2 = c^2 is known as the Pythagorean theorem. This theorem states that in a right-angled triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides. This fundamental relationship in geometry was discovered by the ancient Greek mathematician Pythagoras.

During the severe winter, all but 11 cattle died, leaving only 11 remaining. The initial number of cattle the farmer had, which was 35, is not relevant to the question as it is specified that all but 11 died. Therefore, the correct answer is 11 cattle remaining.

The pattern is increasing by 3 each time. Starting from 3, adding 3 gives 6, then adding 3 again gives 9. Therefore, the next number in the pattern would be 12.

There are 12 inches in 1 foot, so to find the number of inches in 6 feet, you multiply 6 by 12, which equals 72.

A circle is defined as having 360 degrees, which is a convention that has been established in geometry. This measurement allows for easy division of a circle into equal parts, such as quadrants, halves, or thirds. This standardization simplifies calculations and measurements involving circles, making it a widely accepted and practical choice.

The correct answer is obtained by first multiplying 8 and 9 to get 72, then subtracting 2 from the result to get 70.

The square root of a number is the value that, when multiplied by itself, gives the original number. In this case, the square root of 4 is 2 because 2 multiplied by itself equals 4.

10 squared is equal to 100 because when a number is squared, it means that number is multiplied by itself. In this case, 10 multiplied by 10 is 100.

When a number is squared, it means that the number is multiplied by itself. In this case, 9 squared is equal to 9 multiplied by 9, which equals 81.

The team's winning percentage is calculated by dividing the number of games won by the total number of games played and then multiplying by 100. In this case, the team won 80 out of 160 games (80 + 80), resulting in a winning percentage of 50%. This can be expressed as 0.5 when rounded to three decimal points.
