Answer:

11. 2/5 = 40/100 = 40% 12. 29/50 = 58/100 = 58%

Step-by-step explanation:

To convert the given fraction to a fraction of 100, cross-multiply and divide.

2 × 100 = 200 / 5 = 40

Then, whenever you have a number over 100, all you need to do to get the percentage is find the numerator and add a percent sign at the end of the number.

40 ⇒ 40%

Repeat this with the second question.

29 × 100 = 2900 / 50 = 58 ⇒ 58%

Answer:

$x=\frac{\pi}{4}$ and $x=-\frac{3\pi}{4}$

Step-by-step explanation:

We are given that sin x+cos x=cos 2x

We have to solve the given equation for $0\leq x\leq 2\pi$

$sin x+cos x=cos^2x-sin^2x$

Because $cos 2x=cos^2-sin^2$

$sinx+cos x=(sinx +cos x)(sinx-cos x)$

$1 =sin x-cos x$

$sin x=cos x$

$\frac{sinx }{cos x}=1$

$tan x=1$

$tan x=\frac{sinx}{cos x}$

$tan x=tan\frac{\pi}{4}$

$x=\frac{\pi}{4}$

Tan x is positive in I and III quadrant

In III quadrant angle $\theta$ replace by $\theta -\pi$

Therefore, $tan x=tan (\frac{\pi}{4}-\pi)=tan\frac{\pi-4\pi}{4}=tan\frac{-3\pi}{4}$

$x=-\frac{3\pi}{4}$

Help!! 68 POINTS!! !!!!!! math!! look at picture!

-Dominant- [34]

Follow the a² + b² = c² formula

The hypotenuse always equal the c
a and b can be the other two numbers and are interchangeable

plug in 5 and 6 into a and b

(5)² + (6)² = c²
simplify
25 + 36 = c²
add
c² = 61
isolate the c, root both sides
c² = 61
√c²= √61
c = √61

Roots are Irrational numbers, and so D) irrational number should be your answer

hope this helps
