Dina has a circular table. she wants to paint around the edge of the table. If the table has a radius of 3.5 feet, how long is the part of the table she will be painting?
The length of the part of the table that Dina will be painting is 21.991595 feet.
What do you mean by Circumference?Circumference refers to the distance around the edge of a circle. It is the length of the perimeter of a circle and is defined as the product of the circle's radius and its constant pi (π). The formula for the circumference of a circle is:
C = 2πr
where C is the circumference, π is approximately equal to 3.14, and r is the radius of the circle.
The circumference of a circle is an important concept in geometry, trigonometry, and engineering, as it provides a measure of the size and shape of a circular object. Circumference is used in many applications, such as determining the size of wheels, gears, and other circular objects, as well as in the calculation of areas and volumes of circular shapes.
To find the length of the part of the circular table that Dina will be painting, we need to find the circumference of the circle.
Circumference = 2 * π * r
Where r is the radius of the circle. In this case, the radius is 3.5 feet, so:
Circumference = 2 * π * 3.5
Circumference = 2 * 3.14159 * 3.5
Circumference = 21.991595 feet (to 4 decimal places)
So, the length of the part of the table that Dina will be painting is 21.991595 feet.

rest are other pets,
such as birds,
hamsters, and lizards
Part A What fraction of all the animals are not dogs and cats? Explain
how you found your answers.
The fraction of all the animals that are not dogs and cats is 9/40 or 0.225.
How is the fraction determined?The fractions of the dog and cat populations are summed and subtracted from 1, which represents the total population of the animals.
The fractions can also be expressed as decimals using division operations. They can also be depicted in percentages by multiplying the division quotients by 100.
Fractions of Animal Populations in the Shelter:
Dogs = 2/5
Cats = 3/8
2/5 + 3/8 = 31/40
The lowest common factor of 5 and 8 is 40.
Other pets = x
x = (1 - 31/40)
x = 9/40
Thus, since 2/5 of the animal populations are dogs and 3/8 are cats, the rest of the pets, including birds, hamsters, and lizards can be represented fractionally as 9/40.

DEBATE Mrs. Ramirez will divide her class of 24 into two teams for a debate. She writes the numbers 1 through 24 on individual pieces of paper and distributed them randomly, one to each student. The students with even numbers will be part of the red team and the students with odd numbers will be part of the blue team.
If a student is on the blue team, what is the probability that he or she was given the number 19?
Answer:
1/12
Step-by-step explanation:
Total Number of pieces of paper = 24
Total Number of pieces of paper with an odd number on it= 24/2 = 12
Total Number of pieces of paper with Number 19 = 1
Probability of a student on blue team having the Number 19 would be = Number of paper pieces with Number 19/Total number of pieces of paper with an odd number = 1/12
We take only the pieces of paper with an odd number on it as we already know the student is in the blue team so they had to have an odd number.

Use algebraic methods to find as many intersection points of the following curves as possible. Use graphical methods to identify the remaining intersection points. R = 6 sin theta and r = 6 cos theta the intersection point(s) is/are_______
(Type an ordered pair. Type exact answer for each coordinate, using phi as needed. Type the coordinate for theta in radians between 0 and phi. Use a comma to separate answers as needed)
The intersection points are (6, 6) and (-6, -6).
What is Intersection points?
The point at which two lines or curves intersect is referred to as the point of intersection. The point at which two curves intersect is crucial because it is the point at which the two curves take on the same value.
The given curves are the polar equations of two circles with radii 6. To find their intersection points, we can set the two equations equal to each other and solve for Ф.
6 sin(Ф) = 6 cos(Ф)
Dividing both sides by 6 and rearranging terms, we get:
tan(Ф) = 1
This equation has infinitely many solutions, but we are only interested in those that lie in the interval [0, π/2].
Ф = π/4 satisfies this condition and corresponds to the point (6, 6) in Cartesian coordinates.
Since the two curves are circles, they are symmetrical about the origin. Therefore, we can deduce that the other intersection point is (-6, -6).
Therefore, the intersection points are (6, 6) and (-6, -6).

Let f(x) = √x-5 for x ≥ 5
Find f^-1(2)
Answer: To find the inverse of the function f(x), we need to switch the roles of x and y, so that x becomes the dependent variable and y becomes the independent variable. Then, we need to solve for x in terms of y.
Let y = √x - 5, then x = y^2 + 5.
To find f^-1(2), we need to substitute 2 for y in the equation x = y^2 + 5:
x = 2^2 + 5 = 9
So f^-1(2) = 9.
This means that the inverse of f(x) at 2 is 9. In other words, if f(x) = 2, then x = 9.

Deborah is x years old and Syria is y years old . the sum of their ages is 58 if the area is 4 years younger than Syria find the ages of both women
Answer:
Deborah is 27 years old and Syria is 31 years old.
Step-by-step explanation:
Let's say Deborah's age is x and Syria's age is y.
From the given information, we know that:
x + y = 58 (the sum of their ages is 58)
Also, the difference between their ages is 4, which means:
y - x = 4
We can use these two equations to find the values of x and y.
First, we'll solve for y:
y = x + 4
Substituting this value of y into the first equation:
x + (x + 4) = 58
Expanding the left-hand side:
2x + 4 = 58
Subtracting 4 from both sides:
2x = 54
Dividing both sides by 2:
x = 27
So Deborah is 27 years old and Syria is y = 27 + 4 = 31 years old.
