There are 17280 ways 5 letter words can be made from "math is fun" if each word must have 2 consonants and 3 vowels.
Permutation and Combination:
In mathematics, permutation refers to the process of putting all members of a set into a particular order or order. In other words, if the set is already ordered, the permutation of its elements is called permutation. Substitutions occur in more or less noticeable ways in almost every field of mathematics. They often occur when different orders are considered in a particular finite set.
Combining is a way of selecting items from a collection, and (unlike permutation) the order of selection does not matter. In smaller cases you can count the number of combinations. Combining refers to combining n things, taken k times at once, without repetition.
In the word " MATH IS FUN"
The number of Vowels = 03
The number of Consonant = 06
Total Number of words = 09
and, total number of words in even place = 04
The Number of ways = ⁴C₃ = 4 × 3 × 2 ×1/ 3×2×1
= 4
Now,
The vowels can be arranged among themselves in 3! = 6 ways and 5 consonants can fill the remaining 6 places in 5! ,
i.e., 6× 5 × 4× 3× 2× 1 = 720
Therefore,
Total Number of ways = 4 × 6× 720

Cannot be answered because of incomplete data.
It is not possible to determine the number of cubes that can be shipped in this box for $7.95 without more information about the size and weight of the cubes. The weight constraint of ten pounds and the size constraint of 18 cm x 18 cm x 18 cm box only applies to the overall package and not to the individual cubes. The weight and volume of the individual cubes would need to be taken into account in order to determine how many could fit within the package while still adhering to the weight and size constraints.
The correct question should be:

6. 21 and 22 form a linear pair. If m/1 = (5x + 9) and m/2 = (3x + 11), find the measure of
each angle.
7. 21 and 22 are vertical angles. If mZ1 = (17x + 1) and m/2 = (20x-14), find m22.
8. ZK and ZL are complementary angles. If mZK = (3x + 3) and mL = (10x-4), find the
measure of each angle.
Answer:
Since 21 and 22 are vertical angles, they are congruent. Therefore, m/1 = m22.
Using the equation m/1 = (17x + 1) we can find the measure of the angle m22.
m22 = (17x + 1)
Since ZK and ZL are complementary angles, the sum of their measures is 90 degrees.
mZK + mL = 90
Using the equations mZK = (3x + 3) and mL = (10x-4) and substituting them in the equation, we can find the measure of each angle.
3x + 3 + 10x - 4 = 90
13x - 1 = 90
13x = 91
x = 7
Therefore, mZK = (3x + 3) = (3(7) + 3) = 24 and mL = (10x-4) = (10(7) - 4) = 66

WILL MAKE BRAINLIEST! Find the solution to the system of equations. Round to the nearest tenth if necessary.
Answer:
The solution to the system of equations g(x) = x - 1 and f(x) = x^2 - 5 is the point where the two functions intersect, which is the point (1,0).
To confirm this, we can substitute x = 1 into each equation and see that they both equal 0:
g(1) = 1 - 1 = 0
f(1) = 1^2 - 5 = -4 + 1 = -3 = 0
So (1,0) is the solution to the system of equations.
What is meant by absolute term?
The absolute value or modulus |x| of a real number x is the non-negative value of x without regard to its sign.
The absolute value is always a positive value and not a negative number. so those numbers are called absolute values.
It is represented as |a|, which defines the magnitude of any integer ‘a’.
It defines removing any negative sign in front of a number and thinking of all numbers as positive.
Absolute value is a term used in mathematics to indicate the distance of a point or number from the origin (zero point) of a number line or coordinate system.
When x itself is negative (x<0), then its absolute value is necessarily positive

Answer: 183.49 gallons (D)
Step-by-step explanation:
Okay you are trying to find how many gallons of water the water cooler can hold.
So start by using the formula for the volume of a cylinder.
V = πr^2h
First find the radius, which is half the diameter.
The diameter is 2.5 so divide that by 2 to find the radius.
2.5/2 = 1.25
Now that you know the radius, times it by itself:
1.25 x 1.25 = 1.5625
Now multiply 1.5625 by the height, which is 5.
1.5625 x 5 = 7.8125
Now multiply 7.8125 by 3.14
7.8125 x 3.14 = 24.53125
And finally, multiply 24.53125 by 7.48
24.53125 x 7.48 = 183.49375 gallons
Now round to the nearest hundredth:
183.49 gallons

A local pizza shop has a membership program for frequent buyers. The membership
costs $20 per month and members get a discounted price of $2 per slice of pizza.
Alang purchased a membership to this pizza shop. How much would Alang have to
pay the pizza shop if he bought 17 slices of pizza this month? What would be the
monthly cost for a slices of pizza?
Answer:
$32
$22
Step-by-step explanation:
We know
Membership cost per month = $20
Price of a slice of pizza for members = $2
How much would Alang have to pay the pizza shop if he bought 17 slices of pizza this month?
The total cost of Alang on 17 slices of pizza = membership cost per month + prices of 17 discounted pizza
$20 + $2(6) = $32
What would be the monthly cost for a slice of pizza
The monthly cost of Alang a slice of pizza = membership cost per month + price of 1 discounted pizza
$20 + 2 = $22
So,
Alang would have to pay $32 if he bought 17 slices of pizza this month.
The cost of a slice of pizza is $22
find the slope m of the tangent to the curve y = 3/ x at the point where x = a > 0.
The slope m of the tangent to the curve will be m = -3/a^2.
Calculating the slope of the tangent line to the curve y = 3/x at a point where x = a > 0 is an important mathematical concept. To do this, we will first need to find the derivative of the curve y = 3/x.
Let's start by taking a look at the equation for the slope of a line: m = (y2-y1) / (x2-x1). We'll use this equation to find the slope of the tangent line at the point (a, 3/a).
To do this, we'll need to calculate the derivative of the given equation, which is y' = -3/x^2.
At the point (a, 3/a), the derivative is equal to -3/a^2. Therefore, the slope of the tangent line at the point (a, 3/a) is m = -3/a^2.

Complete loss of contact between articulating surfaces. Articular cartilages are damaged, ligaments tear, and the joint capsule is distorted
This is a condition known as ankylosis, and it describes a situation in which two bones lose their contact with each other.
What is ankylosis?Ankylosis can result from a variety of causes, including trauma, infection, or degenerative joint diseases. In cases of trauma, the articulating surfaces of the bones can be damaged, leading to a complete absence of contact between the two bones. Similarly, if an infection is present, the cartilage and ligaments of the joint can be destroyed, leading to ankylosis.
Finally, in cases of degenerative joint diseases, such as arthritis, the joint's articulating surfaces can be damaged, leading to a complete loss of contact between the two bones.
The symptoms of ankylosis vary depending on the severity of the condition. In mild cases, the patient may experience stiffness, pain, and reduced range of motion in the joint. In more severe cases, the joint may become completely immobile, and the patient may have difficulty walking or performing other activities.

A perpendicular force is applied to a beam. The maximum force is 12 kN. The resulted shear function is S(x) = - 2x²
When a perpendicular force is applied to static material (in this case, a beam), shearing forces occur.
Shearing force is calculated as the algebraic sum of all transverse forces acting on either side of a beam or frame section.
First, look at the ratio between forces (in y-direction) and x.
y/x = 12/3
y = 4x
Let S(x) = shear function.
Applying Newton's first law on y-axis:

The value of upper quartile is, 300.
The value of 7th decile is, 250.2.
The value of 35th percentile is, 100.
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
We have to given that;
The donations are as follows,
⇒ 50, 50, 50, 100, 100, 100, 150, 150, 200, 250, 250, 300, 300, 400, 500.
Now, We find the values as;
a) The upper quartile is,
⇒ Qₐ = a/4 (n + 1)
Here, n = 15
So, We get;
⇒ Q₃ = 3/4 (15 + 1)
= 3/4 × 16
= 12
So, Q₃ is in 12th position.
So, The value of Q₃ = 300
The value of 7th decile is,
⇒ D₇ = 7/10 (15 + 1)
= 7/10 × 16
= 11.2
Here, 11.2 is between the position 11th and 12th position which are 250 and 300 respectively.
Then, We get;
⇒ 300 - 250 = 50
Hence, The value of D₇ = 250 + 0.2
= 250.2
Now, The value of 35th percentile is,
⇒ Pₐ = a/100 (n + 1)
⇒ P₃₅ = 35/100 (15 + 1)
= 35/100 × 16
= 5.6
Here, 5.6 is between the 5th and 6th position which are 100 and 200 respectively.
Hence, P₃₅ = 100

a spherical glass bulb measures 31.5 mm in diameter. what is the volume of the bulb in cubic centimeters?
The volume of the spherical glass bulb is approximately 14.1 cubic cm.
To find the volume of a spherical glass bulb, we can use the formula for the volume of a sphere:
[tex]V = 4/3 * pi * r^3[/tex]
Where V is the volume, pi is a mathematical constant (approximately equal to 3.14), and r is the radius of the sphere.
We know the diameter of the bulb is 31.5mm and to find the radius of the sphere, we divide the diameter by 2.
So, radius (r) = 31.5mm / 2 = 15.75mm
Now we can substitute this value into the formula for the volume of a sphere:
[tex]V = 4/3 * pi * (15.75mm)^3[/tex]
We can convert the value of radius from mm to cm by multiplying it by 10^-3
[tex]V = 4/3 * pi * (15.75 * 10^{-3})^3[/tex]
Now we can calculate the value of V
V ≈ 14.1 cubic cm
Therefore, the volume of the spherical glass bulb is approximately 14.1 cubic cm.
