x = 112

This is because

4/7x = 64

7/4 x 4/7 = 64/1 x 7/4

1x= 448/4

x = 112

Hey there!

To solve this, divide 64 and 4/7 . . .

64 = 64/1

4/7 = 4/7

64 x 7 = 448

1 x 4 = 4

Simplifying 448/4 . . .

448/4 = 112 <--------

112= x
x = 112

Hope this helps you.
Have a great day!

Find the complex fourth roots \[-\sqrt{3}+\iota \] in polar form.

____ [38]

Let $z=-\sqrt3+i$ . Then

$|z|=\sqrt{(-\sqrt3)^2+1^2}=2$

$z$ lies in the second quadrant, so

$\arg z=\pi+\tan^{-1}\left(-\dfrac1{\sqrt3}\right)=\dfrac{5\pi}6$

So we have

$z=2e^{i5\pi/6}$

and the fourth roots of $z$ are

$2^{1/4}e^{i(5\pi/6+k\pi)/4}$

where $k\in\{0,1,2,3\}$ . In particular, they are

$2^{1/4}e^{i(5\pi/6)/4}=2^{1/4}e^{i5\pi/24}$

$2^{1/4}e^{i(5\pi/6+2\pi)/4}=2^{1/4}e^{i17\pi/24}$

$2^{1/4}e^{i(5\pi/6+4\pi)/4}=2^{1/4}e^{i29\pi/24}$

$2^{1/4}e^{i(5\pi/6+6\pi)/4}=2^{1/4}e^{i41\pi/24}$

A test is worth 140 points. Ten percent of those points are from one short-answer question. How many points is the short-answer

Vlada [557]

If the total amount of points in a test is 140, and we want to find 10% of those points, we can do the following to figure out how much points the question is worth...

140 points x 10% = 140 x 0.1 = 14 points for the short-answer quesion.
