What do you call a quadrilateral that has exactly 1 pair of parallel sides?

Oh, dude, that's an easy one. So, like, a quadrilateral with exactly 1 pair of parallel sides is called a trapezoid. It's like a fancy word for a shape that's a bit lopsided, you know? So, yeah, next time you see a wonky four-sided figure, just be like, "Hey, that's a trapezoid!"

What is the largest perfect square factor of 11280?

To find the largest perfect square factor of 11280, we need to factorize 11280 into its prime factors, which are 2, 2, 2, 3, 5, 11, and 17. To find the perfect square factor, we pair up the prime factors into their squares, which gives us 2^2 and 3^2. Therefore, the largest perfect square factor of 11280 is 2^2 * 3^2 = 36.

The diameter of the injection cylinder is 8 inches the diameter of the screw is 2.5 inches what is the Intensification Ratio?

Well, isn't that just a happy little question! To find the Intensification Ratio, we simply divide the diameter of the injection cylinder by the diameter of the screw. So, in this case, the Intensification Ratio would be 8 inches divided by 2.5 inches, which equals 3.2. Happy calculating!

Is it possible to make a plus or minus sign on a ti 84?

Well, sweetheart, it's not rocket science. To make a plus sign on a TI-84 calculator, you simply press the "+" key. And to make a minus sign, you press the "-" key. It's as easy as pie, so go ahead and crunch those numbers with confidence.

Did you hear about the antelope who was getting dressed when he was trampled by a herd of buffalo?

The answer to this riddle is: Well, as far as we know this was the first self dressed stamped antelope.

130 Horsepower is how many Miles Per Hour?

Horsepower is a unit of power that measures how much work an engine can do. It is not directly convertible to miles per hour, which is a unit of speed. The relationship between horsepower and miles per hour depends on various factors such as the weight of the vehicle, the efficiency of the engine, and the gearing ratio. In general, a vehicle with 130 horsepower can reach different speeds depending on these factors.

What shape has two pairs of perpendicular sides?

A rectangle is the shape that has two pairs of perpendicular sides. In a rectangle, opposite sides are equal in length and parallel, while adjacent sides are perpendicular to each other. This geometric property makes rectangles ideal for applications such as architecture, engineering, and mathematics.

All the numbers from 1 to 99 are multiplied together Use a pattern to determine the last digit of the product?

As the numbers 1 to 99 are multiplied together, one factor of the product will be 10 which means the last digit must be 0 (a zero).

Without working out the product, it can be seen that every multiple of 5 in the original numbers can be paired up with an even number (that is not a multiple of five) and multiplied together (which produces a multiple of 10) which are all factors of the product together; thus the product will ends with that number of zeros: there are 19 multiples of 5 in the numbers 1-99, so the last 19 digits of the product are all 0 (zero).

How find equilalent ratios?

  1. First, factor out each term.
  2. Reduce the most common factors if necessary.

Example:

2 / 4 = ½

Then, the equivalent ratios to 2 / 4 can be anything that follow this form k / (2k).

What is the name of a 306 angle?

Oh, dude, a 306 angle is called an "acute angle." It's like when you're trying to squeeze into a tight parking spot but you're just not quite perpendicular to the curb. So yeah, it's like less than 90 degrees, but still enough to make you go, "Oh man, I gotta adjust this."

Does (8 -1) make the equation y -9x -1 true?

Well, let's take a moment to look at this equation together. If we substitute 8 for x in the equation y - 9x - 1, we get y - 9(8) - 1. Simplifying that gives us y - 72 - 1. So, the expression becomes y - 73. It seems like there might have been a little mistake in the equation, but that's okay! Let's keep practicing and learning together.

How do you convert from diameter to centimeter?

A diameter is a straight line passing from side to side through the center of a body or figure, especially a circle or sphere. It can be measured in centimeters, but it doesn't convert to them.

Perhaps you meant decimeter. Divide centimeters by 10 to get decimeters.

What word becomes its opposite by changing one letter position?

Oh, dude, you're hitting me with a classic riddle! The word you're looking for is "united." If you switch the position of the letter "i" with the letter "n," you get "untied." It's like magic, but with letters.

How many 3 4 are in 4 whole?

Restate the question: How many times does (3/4) go into 4 wholes?

Answer: divide 4 by (3/4). To divide by a fraction, flip the fraction and multiply. Make the 4 into a fraction by putting a '1' underneath:

(4/1)(4/3) = 4x4/1x3 = 16/3 = 5 1/3.

You can take 3/4 away from 4, 5 1/13 times

(If this isn't your question, try asking it another way.)

What is expanded form for 0.349?

In expanded form, 0.349 is written as 3/10 + 4/100 + 9/1000. This representation breaks down the decimal number into its individual place values, with the numerator representing the digits and the denominator representing the place value position.

What does 11 divide by?

Well, isn't that a happy little question! When you divide 11 by another number, it's like sharing a big, beautiful cake into equal slices. In this case, 11 can be divided by numbers like 1, 11, and even itself, creating a sense of harmony and balance in the mathematical world. Just remember, no matter how you divide it, each slice is special and important in its own way.

Is -4 a solution to the inequality x greater than or equal to 4?

No, -4 is not a solution to the inequality x ≥ 4. In order for -4 to be a solution, it must make the inequality true when substituted for x. Since -4 is less than 4, it does not satisfy the condition of being greater than or equal to 4. Therefore, -4 is not a solution to the inequality x ≥ 4.

Find the sale price of a 130.00 pair of shoes at a 15 percent discount?

Oh, what a delightful question! To find the sale price of those lovely shoes, simply multiply the original price ($130.00) by the discount percentage (15%). Then, subtract that amount from the original price to reveal the discounted price. Remember, mistakes are just happy accidents in the world of math!

What do you get when you cross a computer and a shark?

When you cross a computer and a shark, you get a play on words known as a pun. In this case, the answer would be a "byte" shark, as a byte is a unit of digital information in computing. This type of wordplay relies on the similar sounds or spellings of the words being combined to create a humorous or clever result.

What is the difference between 17 and 8?

The difference between 17 and 8 is 9. This is because subtraction is the operation used to find the difference between two numbers. When 8 is subtracted from 17, the result is 9. In mathematical terms, the equation would be written as 17 - 8 = 9.

What is the least common multiple of 64 and 7?

Well, honey, the least common multiple of 64 and 7 is 448. It's the smallest multiple that both 64 and 7 can divide into evenly. So, there you have it, darling. Math can be a real hoot sometimes!
