The perimeter of a quarter circle is 32.13 what is the quarter circles radius
Answers
Follow below steps:
The problem involves finding the radius of a quarter circle given its perimeter. The perimeter of a full circle is known as its circumference, represented by the formula C = 2πr for a circle of radius r. However, for a quarter circle, only 1/4 of this circumference plus twice the radius (the straight sides of the quarter circle) constitutes the perimeter. Therefore, the perimeter (P) can be expressed as P = (πr)/2 + 2r.
Given that the perimeter is 32.13, we use the formula to set up the equation 32.13 = (πr)/2 + 2r. To solve for r, combine the like terms to get (2 + π/2)r = 32.13 and then isolate r by dividing both sides of the equation by (2 + π/2). Using the approximate value of π = 3.14159, you continue with the arithmetic to find the exact value of the radius.
Remember that precision is important in mathematics. When providing an answer, consider the number of significant figures supplied in the given data and maintain the same level of precision in the final answer.
The radius of the quarter circle is 20.48 units.
To find the radius of a quarter circle given its perimeter, we can start by understanding the formula for the perimeter of a circle.
The perimeter of a full circle is given by [tex]\( P = 2\pi r \)[/tex], where [tex]\( r \)[/tex] is the radius of the circle. Since we are dealing with a quarter circle, the perimeter would be one-fourth of the perimeter of a full circle.
The radius of the quarter circle as [tex]\( R \)[/tex]. Then, the perimeter of the quarter circle is [tex]\( \frac{1}{4} \times 2\pi R = \frac{\pi R}{2} \)[/tex].
The perimeter of the quarter circle is 32.13 units, we can set up the equation:
[tex]\[ \frac{\pi R}{2} = 32.13 \][/tex]
To solve for [tex]\( R \)[/tex], isolate it by multiplying both sides of the equation by [tex]\( \frac{2}{\pi} \)[/tex]:
[tex]\[ R = 2 \times \frac{32.13}{\pi} \][/tex]
[tex]\[ R \approx 20.48 \][/tex]

In the diagram below, AC is perpendicular to BD. Find X.
Answers
6x = 90 + 15
6x = 105
x = 105/6
x = 17.5
Answer: The correct option is
(D) 17.5.
Step-by-step explanation: Given that in the diagram shown, AC is perpendicular to BD, where
[tex]m\angle BEC=(6x-15)^\circ,\\\\m\angle AED=(3y+12)^\circ.[/tex]
We are to find the value of x.
Since AC is perpendicular to BD and they are intersecting each other at the point E.
So, all the four angles made by this intersection are right angles.
That is, angle BEC is also a right angle.
Therefore, we get
[tex]m\angle BEC=90^circ\\\\\Rightarrow (6x-15)^\circ=90^\circ\\\\\Rightarrow 6x-15=90\\\\\Rightarrow 6x=105\\\\\Rightarrow x=\dfrac{105}{6}\\\\\Rightarrow x=17.5.[/tex]
Thus, the required value of x is 17.5.
Option (D) is CORRECT.
What is the solution to this equation?
–5(s – 30) = –10
Answers
Reorder the terms: -5(-30 + s) = -10 (-30 * -5 + s * -5) = -10 (150 + -5s) = -10
Solving 150 + -5s = -10 Solving for variable 's'.
Move all terms containing s to the left, all other terms to the right.
Add '-150' to each side of the equation. 150 + -150 + -5s = -10 + -150
Combine like terms: 150 + -150 = 0 0 + -5s = -10 + -150 -5s = -10 + -150
Combine like terms: -10 + -150 = -160 -5s = -160 Divide each side by '-5'. s = 32
Simplifying s = 32
s-30=2
s=32

Explain how to estimate the product of 18.3(6.37).
Answers
the general rule for estimating is to look at the digit to the right of the digit you want to estimate. Estimating or rounding to the nearest whole number means looking at the digit to the right of the decimal. if you see a digit greater than 5,round up, an if it's less than 5, round down. we would go to the right of 18.3 which would be (6.37), so we're going to to round that to the nearest whole number which would be 7 because it's more than 5. this shows how you estimate 18.3 an (6.37) hope this helps have a good day♡

Rewrite the given expression in the form 2^u where u is a constant or an algebraic expression.
1/2^5 = ? (Put the answer in exponential notation.)
Answers
To rewrite 1/2^5 in exponential notation, remember that 1/2^5 is the same as 2^-5. Therefore, 1/2^5 = 2^-5.
Rewrite the given expression in the form 2u where u is a constant or an algebraic expression.
To rewrite 1/25 in exponential notation, we need to understand that 1/25 is the same as (2-1)5. Using the property of exponents, we can rewrite this as 2-5, where -5 is the new exponent.
Therefore, 1/25 = 2-5, where u = -5.

Write the slope-intercept form of an equation of the line that passes through (2,-4) and (0,6)
Answers
In order to write the slope-intercept form, we have to have slope, and the y intercepts, just as it says in the name. In order to find slope with two points, we use our formula:
y2-y1/x2-x1 =
6-(-4)/0-2 = 6+4/-2 =
10/-2 = -5
Now that we know our slope is negative five, we can use one of those poins to model our slope intercept form, y= mx+b, using our slope, to solve for b, our y intercepts. We'll use (0,6).
We have:
6 = -2(0) + b
6 = 0 + b
6 = b
Now, since we have the slope and y intercept, we can write the equation:
y = -2x + 6
Hope this helps!
we know that
the equation of the line in the slope-intercept form is equal to
[tex]y=mx+b[/tex]

m is the slope of the line
b is the y-intercept of the line

[tex]mAB=-5[/tex]
with the slope m and the point B find the value of b

Ferris wheel is drawn on a coordinate plane so that the first car is located at the point (30,0). What are the coordinates of the first car after a rotation of 270° about the origin?
Answers
Answer:
1. option A is correct i.e., [tex]\(90^{\circ}[/tex].
2. option B is correct.
3. the coordinates of the car after a rotation of [tex]\(270^{\circ}[/tex] is (0,-30).
Step-by-step explanation:
1. The angle of rotation is [tex]\(90^{\circ}[/tex].
To calculate the angle of rotation we can use a protractor and measure the angle between two corresponding angles, using point C as a center.
2. Given: ΔPRS with coordinates P(-3,2), R(2,5) and S(0,0) is rotated through an angle of 270°, the new image will be as follows;
The formula for rotation through 270° is: (x,y) → (y,-x)
hence our image will be at point:
P(-3,2)→P'(2,3)
R(2,5)→R'(5,-2)
S(0,0)→S'(0,0)
from the above, the approximate image will be option B.
3. Given: Ferris wheel is drawn on a coordinate plane at the point P(30,0). The coordinates of the car after a rotation of [tex]\(270^{\circ}[/tex] is (0,-30).
Because the formula for rotation through 270° is: (x,y) → (y,-x).
So, point P(30,0)→P'(0,-30).

2. Remember that the domain of a function are the set of the x-values of the function; the range of a function are the set of y-values of the function. From our previous point, we can infer that the ordered pairs of the function are: (0,0), (3,24), (5,40), (7,56), (10,80), and (12,96). The y-values and hence the range of the function are: 0, 24, 40, 56, 80, 96. Remember that in the quadrant I both the x-coordinates and the y-coordinates are positive. Since all the coordinates of our points are positive, we can conclude that the correct answer is:

The solution to the equation is 6 if equation is 6(2x - 11) + 15 = 21 the answer is 6.
What is an arithmetic operation?It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has a basic four operators that is +, -, ×, and ÷.
We have a mathematical equation:
6(2x - 11) + 15 = 21
DIstributive property:
12x - 66 + 15 = 21
Subtraction property:
12x -51 = 21
Add 51 on both side:
12x -51 + 51 = 21 + 51
12x = 72 (adding like terms)
x = 6 (divide by 12 on both side)
Thus, the solution to the equation is 6 if equation is 6(2x - 11) + 15 = 21 the answer is 6.
