The diameter of the circle C/13
The formula provides the circumference of a circle.
The circumference of any shape in mathematics designates the path or limit that surrounds the shape. In other words, the circumference, sometimes referred to as the perimeter, aids in figuring out how long the contour of a shape is. The size and perimeter of a circle are, as we all know, its two most important properties.
C = pi * d, where d is the diameter and c is the circumference.
C = pi * 13 gives the diameter as 13.
Subtract 13 from each side, C/13 = d.
Dimensions are C/13.

Answer:
52.5
Step-by-step explanation:
Since ABCD is a parallelogram, we know that angle ABC and angle ADC are congruent, and since angle ABC is 105, angle ADC is also 105. Since ADC lies on a line, which is 180 degrees, we can calculate ADE by doing 180 - 105 = 75
Next, we must realize that since ED is equal to AD, then angle AED is congruent to DAE. So now we have the three angles for triangle ADE
x (angle AED), x(angle DAE) and 75(angle ADE)
Since we know that a triangle has 180 degrees, we just formulate the following:
2x + 75 = 180
2x = 105
x = 52.5

What is meant by quotient?The quotient is the number we get when we divide two numbers. For instance, in the case of 8 4 = 2, where the division result is 2, it is the quotient. The divisor is 4, and the dividend is 8.
The remnant is the amount that does not wholly enter the divisor, whereas the quotient is the number of times a division is completed to the fullest extent possible. By way of illustration, 42 is the quotient and 1 is the remainder when 127 is divided by 3 to provide 42 R 1.

Answer:
3⅛ ÷ 1⅔ = 1.9083969465648855.
Step-by-step explanation:
To arrive at this answer, we can first convert 3⅛ and 1⅔ to fraction form.
3⅛ can be written as 3 + 1/8, which is equal to 3 + 1/8 = 25/8.
Similarly, 1⅔ can be written as 1 + 2/3, which is equal to 1 + 2/3 = 5/3.
Therefore, 3⅛ ÷ 1⅔ is equal to (25/8) ÷ (5/3) = (25/8) * (3/5) = (325)/(85) = 75/40 = 1 + 35/40 = 1 + 35/40 = 1.875.
This is the exact result, but if you want to round to the nearest hundredth, the result would be 1.91.
Solve for x.
3 1/2 ≥ 1.4x
A. x ≥ 2 1/2
B. x ≤ 2 1/2
C. x ≥ 4 9/10
D. x ≤ 4 9/10
To solve for x, we need to get x by itself on one side of the equation. To do this, we can start by subtracting 1.4x from both sides of the equation. This gives us:
3 1/2 - 1.4x ≥ 0
Next, we can simplify the left side of the equation to get:
7/2 - 7/5x ≥ 0
Now we can divide both sides of the equation by -7/5 to get:
-5/2x ≤ -7/2
Finally, we can multiply both sides of the equation by -2/5 to get:
x ≥ 4 9/10
Therefore, the solution is x ≥ 4 9/10, which corresponds to answer choice C.
Answer:
x ≥ 4 9/10 C:)

A high school student working part time as a shelf stocker had a gross income of $6675 last year. If his federal tax rate was %10 and his state tax was 3% what was the amount withheld from his Pat last year in federal tax, state tax, and FICA combined?
A. 867. 75
B. 667. 50
C. 200. 25
D. 1378. 39
The total amount withheld from the student's pay last year in federal tax, state tax, and FICA is $667.50 + $201.25 = $868.75
What is percentage?Percentage is a way of expressing a number as a fraction of 100. It is often denoted using the symbol "%" (percent sign). Percentages are used to express how much of something there is in relation to the whole. For example, if a student answers 80% of the questions correctly on a test, it means they answered 80 out of 100 questions correctly.
What is tax?A tax is a financial charge imposed by a government on individuals, businesses, or other entities to raise revenue for government spending. Taxes are typically based on a percentage of income or sales, and can be levied on various forms of income, including wages, salaries, and profits. The purpose of taxation is to fund government programs and services, such as roads, schools, and national defense. Taxes can also be used to redistribute wealth and influence economic behavior.
The amount withheld from the student's pay last year in federal tax is $6675 x 0.1 = $667.50
The amount withheld from the student's pay last year in state tax is $6675 x 0.03 = $201.25
The total amount withheld from the student's pay last year in federal tax, state tax, and FICA is $667.50 + $201.25 = $868.75
So the answer is A. 867.75

Q 5 a) calculate the value of d
Answer:
This is not possible.
Step-by-step explanation:
6 m = 600 cm
A triangle with a 600 cm leg and a 10 cm hypotenuse is impossible
If the 6 m should have been 6 cm, then:
Using the Pythagorean theorem:
base² = 10² - 6² = 100 - 36 = 64
base = √64 = 8
d² = 8² + 15² = 64 + 225 = 289
d = √289 = 17 cm , not meters

So, (2m + 4)(m + 5) is the factored form of 2m² +13m +20.
Define Factorial.The factorial of a non-negative integer n, represented by n! is the product of all positive integers less than or equal to n. It is the mathematical operation that is applied to a non-negative integer.It is also used in many areas of mathematics, including calculus and number theory, as well as in many areas of science, including physics, chemistry, and computer science.
What is variables and constants ?A constant has a fixed value and does not vary over time. For instance, the size of a shoe, a piece of clothing, or any other article of clothing will never alter. x+y = 8 is an algebraic equation, and 8 is a constant that cannot be altered. Variables are concepts that change or fluctuate throughout time.
To factor a trinomial of the form "ax² + bx + c," we can use the following steps:
First, we need to determine two numbers that multiply to give us "c" and add to give us "b." In this case, the two numbers are 4 and 5 because 4 x 5 = 20 and 4 + 5 = 9, which is equal to "13m".
Next, we can factor the trinomial into the form (ax + b)(cx + d) by grouping the middle term and the constant term together.
So, the factored form of the trinomial is (2m + 4)(m + 5)
So, (2m + 4)(m + 5) is the factored form of 2m² +13m +20.

What is the difference of the two polynomials 9x² 8x )-( 2x² 3x?
The difference of the two polynomials (9x² + 8x) - (2x² + 3x) is 7x² + 5x.
To find the difference of these two polynomials, we need to subtract the second polynomial from the first. This is done by subtracting each term of the second polynomial from the corresponding term of the first polynomial. In this case, we have:
(9x² + 8x) - (2x² + 3x) = (9x² - 2x²) + (8x - 3x) = 7x² + 5xSo, the difference of the two polynomials (9x² + 8x) - (2x² + 3x) is 7x² + 5x.
The terms that are being subtracted are the terms that have the same degree, meaning the same exponent of the variable.
It's worth noting that the order of subtraction doesn't change the result and that we can subtract polynomials of any degree and size, and it will work the same way.

Answer:
There was a discount of 20% on the pair of pants.
Step-by-step explanation:
10% of $34 would be $3.40 meaning 20% would be double, which is $6.80.

This approximates to roughly 6/7 = 0.8571
========================================================
Explanation:
Let's define the following
A = number of people who passed the test, and did the hwB = number of people who passed the test, but didn't do the hwC = number of people who failed the test, but did the hwD = number of people who failed the test, and didn't do the hwThere are 30 students in the class total. This must mean A+B+C+D = 30.
We know that "There were 7 students who failed the test and also did not complete the assignment", meaning we can say D = 7.
We can also say A+B = 21 because this is the entire group of people who passed the test (whether they did the hw or not).
This means:
A+B+C+D = 30
(A+B)+C+D = 30
(21) + C + 7 = 30
C+28 = 30
C = 30-28
C = 2
We have 2 people who failed the test, but did the hw.
Because 20 students did the hw, we know that
A+C = 20
A+2 = 20
A = 20-2
A = 18
We have 18 students who passed the test and did the hw. This is out of 21 students who passed. From here on out, we only focus on this group of students because of the phrasing "given that they passed the test". This means we know 100% that whoever we picked, they passed the test.
The probability we're after is therefore:
18/21 = (3*6)/(3*7) = 6/7
