Answer:

B

Step-by-step explanation:

First find the circumference of the circle with radius of 9 inches:

C=2\pi r=2\pi \cdot 9=18\pi \ inches

The full angle has 360°, so, to find the length of the arc DE, you can write:

360^{\circ}\ - \ 18\pi \\ \\145^{\circ}\ - \ x

which yields a proportion:

\dfrac{360}{145}=\dfrac{18\pi}{x}\\ \\360x=145\cdot 18\pi\\ \\x=\dfrac{145\cdot 18\pi }{360}=\dfrac{145\pi}{20}=7.25\pi\approx 22.8\ inches

Bumek [7]
The answer should be b. because 4(4) = 16 and that’s closer to 18.4 than the others.

Which equation can pair with 3x + 4y = 8 to create a consistent and independent system?
Hunter-Best [27]
There isn't any choices given in this problem but I can give you a tip to answer these kinds of problem. When you say independent, it means that the equation cannot be algebraically altered to result to 3x + 4y = 8. So the equation 6x + 8y = 16 is not an independent equation since when you divide each side by 2 it will result to 3x + 4y =8. You get the idea. <span />
