Answer: 6.87
Step-by-step explanation:
21.2 / 145.65
Move to the decimal to the right 1 time to make 21.2 to 212 and 145.65 to 1456.5.
Then you want to look for a number you can multipl 212 into the 1456.
In this case, 212 times 6 because it equals 1272.
If you multiply 212 times 7, you get 1484 (which is over the number of 1456 { we dont want that}).
Then you continue multiplying the number until you get to 0, or in other words, a remainder. In which I got, 6.870
How do you calculate the area of a circle within a circle?
To calculate the area of a circle within a circle, you can use the following formula Area = πr^2 - πr1^2
How do you calculate the area of a circle within a circle?Where,r is the radius of the larger circler1 is the radius of the smaller circlePi, which is roughly equivalent to 3.14159, is a mathematical constant.The area of a circle is given by the formula πr^2, where r is the radius of the circle.In the case of a circle within a circle, the area of the larger circle can be found by using this formula with the radius of the larger circle.The area of the smaller circle can also be found using the same formula, but with the radius of the smaller circle.The difference between the areas of the two circles represents the area of the circle within the circle.To find the area of the circle within the circle, simply subtract the area of the smaller circle from the area of the larger circle.It's important to note that this formula assumes that the smaller circle is fully contained within the larger circle, with no overlap.If there is overlap between the two circles, a different method may need to be used to calculate the area of the circle within the circle.To learn more about area of circle refer:

Decreasing the sample size, while holding the confidence level the same, will do what tothe width of your confidence interval?a.make it bigger b.make it smaller c.it will stay the same d.cannot be determined from the given information
Decreasing the sample size, while holding the confidence level the same, will make the width of your confidence interval bigger. So option a. is correct.
The width of a confidence interval is a measure of the degree of uncertainty in the estimate of the population parameter. It is determined by the sample size, the confidence level, and the standard deviation of the population.
When the sample size decreases, the standard deviation of the sample estimate increases, making the width of the confidence interval larger. This reflects the increased uncertainty in the estimate of the population parameter.
Therefore, decreasing the sample size while holding the confidence level the same will result in a wider confidence interval.

find parametric equations for two circles c1 and c2 in space such that ¥c1 and c2 have the same radius; ¥c1 and c2 intersect at the points p(2,1,1) and q(2,1,1) and nowhere else.
The parametric equations for the two circles are
c1(t) = R cos(t) i + R sin(t) (0, 1, 0) + (2, 1, 1),c2(t) = R cos(t) (1, 0, 0) + R sin(t) (0, 1, 1)/√2 + (2, 1, 1).How to find the parametric equationsA general parametric equation for a circle can be given as:
c(t) = R cos(t) i + R sin(t) j + k,
where
R is the radius and (i, j, k) is a unit vector perpendicular to the plane of the circle.We can find two unit vectors perpendicular to the plane containing points p and q:
v1 = (1, 0, 0) and v2 = (0, 1, 1)/sqrt(2)
Thus, the two circles c1 and c2 with radius R and intersecting at p and q can be represented as:
c1(t) = R cos(t) i + R sin(t) (0, 1, 0) + (2, 1, 1),

The negation of the statement “for all x, there exists a y such that x is greater than y” can be expressed as “there exists an x such that for all y, x is less than or equal to y”. This negation is written as ∃x∀y(x ≤ y). This is done by switching the existential and universal quantifiers, and inverting the inequality sign.

The magnitude of sum of the given two vectors is 5 .
Describe a vector.A vector is an entity that possesses both magnitude and direction.
Ordinary quantities that are given with direction are called vectors; in other words, a vector quantity is any magnitude that is given with a direction. Scalar quantities refer to any quantity that is defined without any direction. In physics, vector quantities have a significant impact.
Examples of vectors include displacement, velocity, acceleration, force, and others that show both the direction and the size of a quantity.

What is the measure of angle W ?
Answer:
Angle W is 100 degrees
---------------------------------
Angle W is the exterior angle of the given triangle.
We know that exterior angle is the sum of remote interior angles.
It gives us:
W = 33 + 67 = 100how many degrees are there on both the celsius and kelvin temperature scales, between the normal freezing and boiling points of water?
There are 100 degrees between the normal freezing and boiling points of water.
On the Celsius temperature scale, the difference between the normal freezing point (0°C) and the normal boiling point (100°C) of water is 100°C - 0°C = 100°C.
Celsius, also called centigrade, scale based on 0° for the freezing point of water and 100° for the boiling point of water.On the Kelvin temperature scale, the equivalent temperatures for the normal freezing and boiling points of water are 273.15 K and 373.15 K, respectively. The difference between these two temperatures on the Kelvin scale is 373.15 K - 273.15 K = 100 K.

There are 13! x 4 possible sequences where all cards of the same suit are together, and 13! possible sequences where all the clubs are together.
A standard deck of 52 cards contains 4 suits: spades, hearts, diamonds, and clubs.
(a) To find how many sequences have all cards of the same suit together, we need to find the number of sequences where all the cards of the same suit are together.
There are 4 possible suits, and each suit contains 13 cards.
So, the number of sequences where all the cards of the same suit are together is 13! x 4.
(b) To find how many sequences have all the clubs together, we need to find the number of sequences where all the clubs are together.
There are 13 clubs, and each club card can be placed in any order.
So, the number of sequences where all the clubs are together is 13!
Therefore, there are 13! x 4 possible sequences where all cards of the same suit are together, and 13! possible sequences where all the clubs are together.

5 bananas and 1 apple (F)
For the second question, Andre's statement is incorrect. The first type of bus holds 50 people and the second type of bus holds 56 people. In total, 3 of the first type of bus and 3 of the second type of bus can only hold 3 * 50 + 3 * 56 = 318 people. However, there are 280 elementary school students and 40 adults, which is a total of 280 + 40 = 320 people. Hence, Andre's statement is incorrect.
For the third question, the reason why equations A and B are not equivalent is because the variables in Equation B are expressed in a different form than in Equation A. Equation A shows the relationship between the variable x and the constant value 13 and 48, while Equation B only shows the relationship between the variable x and the constant value 35. To determine if they are equivalent, we need to solve both equations for x and compare the solutions. Solving Equation A gives us x = (48 + 13) / -5 = 5.6. Solving Equation B gives us x = 35 / 5 = 7. Since the solutions are different, the equations are not equivalent.

exact shape function of tapered bar element
In FEM, nodal displacement is calculated using the matrix equation shown below: [K] is the global stiffness matrix, [u] is the displacement (solution) vector, and [F] is the vector of forces.
Describe function.A function is something that connects an input to an output.
Then, they are interpolated over entire elements using shape functions, which are essentially polynomials of different orders. Although quadratic shape functions, like a quadratic curve, are becoming common, linear shape functions, like a straight line used to approximate a distance between two locations, are the most fundamental. Even higher order shape functions (like cubic) exist, but they are rarely used in practical settings. The calculation of an element's stress uses Gauss Points rather than nodes. You can look up the GP locations for any given kind of element, but for the purposes of this discussion, let's just talk about singles.
Since [K] is the global stiffness matrix, [u] is the displacement (solution) vector, and [F] is the vector of forces, the matrix equation presented below is used to determine nodal displacement.

Answer:
48°
Step-by-step explanation:
A/C, 6x - 4 + 8x - 18 + 5x - 7 = 180°
or, 19x - 29 = 180°
or, x = 209 ÷ 19 = 11
