Arc XY located on circle A has a length of 40 centimeters. The radius of the circle is 10 centimeters. What is the measure of the corresponding central angle for XY in radians?
The measure of the corresponding central angle for XY in radians is; 229.1°
What is the angle subtended by the arc?We know that an arc is a part of the entire perimeter of a circle.
Radian is defined as a unit of plane angular measurement that is equal to the angle subtended by the circle at the center by an arc that is of the length equal to the radius.
We also know that the circle as a whole contains 2π radians. Now, at first we are required to find the perimeter of the circle.
Perimeter of the circle is given by the formula 2πr.
Thus, perimeter of the circle = 2πr = 2π * 10 =20π = 62.851cm
Hence value of arc in radians = 40/62.851 * 2π = 0.636 x 2 π = 1.272π
Radian can be converted to degree by multiplying the radian measure by 180/π
Therefore, angle subtended by arc in degrees =1.272 π * 180 /π =229.1 °
Hence the angle subtended by arc is 229.1°

#15: m∠NST = ____°
need answer
Answer:
∠ NST = 59°
Step-by-step explanation:
∠ NST and ∠ LSN form a right angle , that is
∠ NST + ∠ LSN = 90
3x - 1 + 2x - 9 = 90
5x - 10 = 90 ( add 10 to both sides )
5x = 100 ( divide both sides by 5 )
x = 20
Then
∠ NST = 3x - 1 = 3(20) - 1 = 60 - 1 = 59°

First order equations include linear equations. In the coordinate system, the linear equations are defined for lines. A linear equation in one variable is one in which there is a homogeneous variable of degree 1 (i.e., only one variable). Multiple variables may be present in a linear equation. Linear equations in two variables, for example, are used when a linear equation contains two variables. Examples of linear equations include 2x - 3 = 0, 2y = 8, m + 1 = 0, x/2 = 3, and 3x - y + z = 3.

A 7 cm string that is fastened at both sides is plucked. what is the wavelength of the n = 4 standing wave?
The wavelength of the n = 4 standing wave is 3.5cm.
Standing Waves:
A standing wave is a stationary wave, which means that the wave oscillates in time but the peak amplitude does not move in space. This can happen in a stationary medium from an interference due to two waves traveling in opposite directions. For a harmonic wave, the string's displacement in the y-direction from the x-position and time t can be calculated by using the expression
y(x ,t)=2Asin(2πxλ)cos(ωt)
where A is the maximum displacement in the y-direction, λ
is the wavelength, and ω is the angular frequency. Given a taut string of length L, and assuming the the driving force is at x=0, the boundary conditions are
y(0,t)=0y(L, t)=2Asin(2πLλ)cos(ωt)=0
Given the latter boundary condition, a standing wave occurs when sin(2πLλ)=0=sin(nπ). The condition for the standing wave is then of the form n=2Lλ.
The condition where the standing wave occurs is given by the expression n=4Lλ, where n is a positive integer value, L is the string length, and λ is the wavelength. We calculate the wavelength of an n=4 standing wave as follows:
λ=4Ln=4(7 cm) / 2
= 14 /2
= 3.5cm.

One bar of candy A and two bars of candy B have 768 calories. Two bars of candy A and one bar of candy B contain 783 calories. Find the caloric content of each candy bar.
Answer:
Bar A : 266 calories; Bar B : 251 calories
Step-by-step explanation:
Assume bar A's caloric content is "a" and bar B's caloric content is "b".
1. a + 2b = 768
2. 2a + b = 783
Add both equations together.
3. 3a + 3b = 1551
Divide both sides by 3.
4. a + b = 517
Subtract equation 4 from equation 1.
5. a + 2b - a - b = 768 - 517
Evaluate.
6. b = 251
Subtract b's value from equation 2.
7. 2a + b - b = 783 - 251
Evaluate.
8. 2a = 532
Divide both sides by 2.
9. a = 266

Are any of the subsets of the real number system (real numbers, whole numbers, integers, rational
numbers, or irrational numbers) are closed under multiplication? Which onest Explain why
The collection of all rational and irrational numbers, represented by the letter R, is known as a real number. A real number can therefore be either rational or irrational.
The set of natural numbers N = {1, 2, 3, 4, 5, . . .}
The set of integers Z = {. . ., –3, –2, –1, 0, 1, 2, 3, . . .}
The set of rational numbers Q = {x: x = a/b; a, b ∈ Z and b ≠ 0}
The set of irrational numbers, denoted by T, is composed of all other real numbers.
Thus, T = {x : x ∈ R and x ∉ Q}, i.e., all real numbers that are not rational.
Some of the irrational numbers include √2, √3, √5, and π, etc.
Some of the apparent relations among these subsets are:

What is nominal rate of interest?In finance and economics, the nominal interest rate or nominal rate of interest is either of two distinct things: the rate of interest before adjustment for inflation; or, for interest rates "as stated" without adjustment for the full effect of compounding.
Given:
nominal rate of interest= 2%
expected inflation rate = 10 %
We know,
nominal rate = real interest rate + inflation rate
and, real interest rate= nominal rate - inflation rate
then,

a building in a city has a rectangular base. the length of the base measures 65ft less than three times the width. the perimeter of this base is 910ft. what are the dimensions of the base?
The dimension of the base of the rectangular building is 340 x 135ft.
Perimeter of Rectangle:
The definition of perimeter of the rectangle is the total length or distance of its boundary on all sides.
The general formula to calculate the Perimeter of a rectangle is,
P = 2(l + w)
Where,
l represents the length of the rectangle
w represents the width of the rectangle.
Given,
The building in a city has a rectangular base. the length of the base measures 65ft less than three times the width.
The perimeter of this base is 910ft.
Now, we need to find the dimensions of the rectangular base.
According to the given details, the values of
L = 3W - 65
W = W
P = 910
Apply the values on the formula, then we get,
=> 910 = 2 * (L + W)
=> 910/2 = (L + W)
=> 455 = L + W
Apply the value of L,
=> 475 = 3W - 65 + W
=> 475 + 65 = 4W
=> 540 = 4W
=> 540/4 = W
=> W = 135
Apply the value of W as 135, in order to get the value of L,
=> L = 3*135 - 65
=> L = 405
=> L = 340
Therefore, the dimension of the rectangular base is 340 x 135 ft.

Step-by-step explanation:
In an apartment building block there are apartments with 2 rooms and with 3 rooms. in the building there are 20 apartments and 45 rooms in total. how many appartments with 3 rooms are in the building?
Using algebraic expressions and equations to solve this problem, there are 15 apartments with 2 rooms and 5 apartments with 3 rooms.
An algebraic expression is a number, variable, or the combination of both and operational symbols. On the other hand, an equation is the equality of two expressions separated by "=".
If there are 20 apartments, we can write the equation for the sum of two different kind of apartments.
let x = number of apartments with 2 rooms
y = number of apartments with 3 rooms
x + y = 20 (equation 1)
If there are x apartments with 2 rooms and y apartment with 3 rooms and there are 45 rooms in total, we can express this as the equation:
2x + 3y = 45 (equation 2)
Rewriting equation 1 as an equation of y in terms of x,
x + y = 20 (equation 1)
y = 20 - x
Substitute this expression of y to equation 2, and solve for x.
2x + 3y = 45 (equation 2)
2x + 3(20 - x) = 45
2x + 60 - 3x = 45
-x = 45 - 60
-x = -15
x = 15
Substitute the value of x in either equation 1 or 2 and solve for y.
x + y = 20 (equation 1)
15 + y = 20
y = 20 - 15
y = 5
If x is the number of apartments with 2 rooms and y is the number of apartments with 3 rooms, then there are 15 apartments with 2 rooms and 5 apartments with 3 rooms.
