Select the correct answer<br> Solve this equation<br> X+4/6x = 1/x

laila [671]

Answer:

A) x = 0, 2

Step-by-step explanation:

(x + 4) / 6x = 1 / x

this is a proportion, so you can cross-multiply and get:

x(x + 4) = 6x

x² + 4x = 6x

x² - 2x = 0

x(x - 2) = 0

x = 0

x - 2 = 0 so, x = 2

Given each of the following areas, what would be the radius of each circle? a. A = 530.66 m2 b. A = 907.46 sq. ft. c. A = 379.94

ra1l [238]

Area for a circle is $A= \pi r^2$ . We will fill in each area and then solve for the radius. $530.66m^2= \pi r^2$ and $\frac{530.66m^2}{3.14}=r^2$ . ∴ $169=r^2$ and r = 13. For b, $907.46ft^2= \pi r^2$ and $\frac{907.46ft^2}{3.14}=r^2$ . $289=r^2$ , ∴ r = 17. For c, $379.94mi^2= \pi r^2$ , and $\frac{379.94mi^2}{3.14}=r^2$ . ∴, $121=r^2$ and r = 11. For d, $1962.5cm^2= \pi r^2$ , and $\frac{1962.5cm^2}{3.14}=r^2$ . ∴, $625=r^2$ so r = 25. And there you have it!
