Arc cd located on circle a has a central angle of 135 the radius is the circle is 24 centimeters what is the length of arc cd

kherson [118]

$\textit{arc's length}\\\\ s = \cfrac{\theta \pi r}{180}~~ \begin{cases} r=radius\\ \theta =\stackrel{degrees}{angle}\\[-0.5em] \hrulefill\\ r=24\\ \theta =135 \end{cases}\implies s=\cfrac{(135)\pi (24)}{180}\implies s=18\pi ~cm$

WORTH 100 POINTS WORTH 100 POINTS WORTH 100 POINTS WORTH 100 POINTS HELPPPPP

LenKa [72]

Answer:

x - 4y = 22

Step-by-step explanation:

Given line:

x - 4y = 20

Convert the equation into slope-intercept form:

x - 4y = 20
4y = x - 20
y = 1/4x - 5

It has a slope of 1/4.

Parallel lines have equal slopes.

Find the parallel line lines that passes through the point (2, - 5):

y = 1/4x + b

Substitute x and y values to work out the value of b:

- 5 = 1/4*2 + b
- 5 = 1/2 + b
b = - 5 - 1/2
b = - 11/2

The line is:

y = 1/4x - 11/2

Covert this into standard form:

y = 1/4x - 11/2
4y = x - 22
x - 4y = 22

The Oliver Company plans to market a new product. Based on its market studies, Oliver estimates that it can sell up to 5,500 uni

Ghella [55]

For the Oliver Company to break even, the total revenue must equal the sum of the variable costs and the fixed cost. Mathematically, this can be represented as: Total revenue = 0.4*(Total revenue) + (Fixed Costs) Let the number of units sold be x. then, 7*x = 0.4*(7*x) + 6300 Thus, x = 6300/(0.6*7) = 1500 units. Thus the company will have to sell 1500 units to break even.

Elena-2011 [213]

A function for this would be m = 50 + 4.25t. The $50 is the one time thing. We must multiply the tips by 6. 4.25 * 6 = 25.50. 50 + 25.50 is 75.50. Joe would make $75.50 after 6 hours.
