The sum of 4 numbers is 83095 two of the numbers are 29854 and 17031 the third and fourth number are the same what is the third number?

Well, honey, if the sum of 4 numbers is 83095 and two of them are 29854 and 17031, then the sum of those two is 46885. Subtract that from 83095 and you get 36210. Since the third and fourth numbers are the same, divide that by 2 and you get 18105. So, the third number is 18105.

What quadrilateral has two pairs of equal lines one pair of equal angles and one reflex angle?

Oh honey, you're describing a kite. It's like geometry's version of a fashionable accessory - two pairs of equal sides, a pair of equal angles, and that one sassy reflex angle to keep things interesting. It's the quadrilateral that's all about balance and style.

What is the difference between Solve and Evaluate and Simplify?

Solve: Find a definite answer to X or Y or whatever.

Evaluate: Find out a definite answer to the equation.

Simplify: No definite answer.

To evaluate usually implies plugging in the values for the variables.

i.e. Evaluate 3x²+2 when x=5. The value of the expression (or its evaluation) is 77 ■

What is the area of a circle with the circumference 6.28?

To find the area of a circle when given the circumference, you can use the formula A = (C^2) / (4π), where A is the area, C is the circumference, and π is approximately 3.14159. In this case, with a circumference of 6.28, the area would be (6.28^2) / (4 * 3.14159) ≈ 5 square units.

How do you get to 21 by using 1 5 6 and 7?

To get to 21 using 1, 5, 6, and 7, you can calculate (6 + 5) x (1 + 7) = 11 x 8 = 88. This equation follows the order of operations (parentheses first, then multiplication) to achieve the desired result of 88.

What is the y intercept of 5x-2y40?

Impossible to tell, as you have not equarted it with anything.

However, if you mean 5x - 2y = 40

The algebraically rearranging

2y = 5x - 40

Divide both sides by '2'

Hence

y = ( 5/2) x - 20

The y-intercepy is when x= zero(0)

Substituting

y = ( 5/2)0 - 20

y = 0 -20

y = -20 The y-interncept.

Remember for ALL straight lines. of the form y = mx + c

'm' is the slope/gradient, and 'c' is the y-intercept.

What is a piece of evidence used to solve a mystery or problem?

A piece of evidence used to solve a mystery or problem is typically referred to as a "clue." Clues are specific details or information that provide insight into the situation at hand, helping to unravel the mystery or address the problem. These can include physical evidence, witness statements, documents, or any other relevant information that sheds light on the issue being investigated. Analyzing and interpreting clues is a crucial aspect of problem-solving and detective work.

What is longer a 220 yard or 200 meter?

A meter is longer than a yard, so 200 meters is longer than 220 yards. To convert yards to meters, you can use the conversion factor 1 yard is equal to 0.9144 meters. Therefore, 220 yards is approximately equal to 201.168 meters, making 200 meters longer than 220 yards.

How much does 15 go into 120?

Well, isn't that just a happy little math problem! If you take 120 and divide it by 15, you'll find that it goes in 8 times. Just imagine each 15 fitting neatly into 120, creating a lovely pattern of numbers. Remember, there are no mistakes in math, just happy little calculations.

How many numbers can you make with 4 digits used only once?

Because of the question's ambiguity, it is hard to tell exactly what is meant. However, to cover all possibilities:

If there are four numbers and each is used once, there are 4! = 4 x 3 x 2 x 1 = 24 different combinations.

If there are the 10 digits used to make a four-digit number, using each once, we have 10!/(10-4)! = 10!/6! = 10 x 9 x 8 x 7 = 5040 different combinations.

Or does he mean this?

If in class pupil 47 is opposite pupil 16 when the group is seated in a circle how many students are in the pe class?

To determine the total number of students in the PE class, we need to calculate the number of students between pupil 47 and pupil 16 in a circular seating arrangement. In a circle, the number of students between two individuals is equal to the total number of students minus the absolute difference between their positions. In this case, the total number of students in the PE class would be 31, calculated as the total (47) minus the difference between pupil 47 and pupil 16 (31).

What shapes have a perimeter of 15 and an area of 16?

Oh, what a happy little question! Let's think about shapes that could have a perimeter of 15 and an area of 16. One shape that comes to mind is a rectangle with dimensions 4 by 4. Another possibility is a square with sides of length 4. These shapes show us that there can be different ways to create beautiful combinations of perimeter and area.

Does algebra have the schwa sound?

The schwa sound is commonly found in unstressed syllables in English words, such as the second syllable of "sofa" or the second syllable of "banana."

What is the square root of 52 in radical form?

52=2*2*13

sqrt(52)=sqrt(2)*sqrt(2)*sqrt(13)

sqrt(52)=2*sqrt(13)

What is 8.004 in expanded form?

In expanded form, the number 8.004 can be written as 8 + 0.0 + 0.004. This breaks down the number into its individual place values: 8 for the whole number part, 0.0 for the tenths place value, and 0.004 for the thousandths place value. This representation helps to clearly show the value of each digit in the number.

What is 84.95 as a decimal?
