match the numbers with the correct label. i will MARK YOU BRAINLIEST if your right, only answer if you know what your doing!!! :

Answer:

a = 1/7, b = 0.2, c = 3/9

Step-by-step explanation:

$0.2=\frac{2}{10} = \frac{1}{5}$

$\frac{1}{7}$

$\frac{3}{9}=\frac{1}{3}$

$\frac{1}{5} > \frac{1}{7}$ placing it farther along the number line, making 0.2 the red label (b)

$\frac{1}{7}$ is the smallest fraction that you are given, so it will be closest to 0, making it the blue label (a)

$\frac{1}{3} > \frac{1}{4}$ so $\frac{3}{9}$ is the green label (c)

Needed quickly like asap

Artemon [7]

It is 18/20 and in simplest form it is 9/10.

Steps:
1.You have to add all the shirts, 2+7+11. This is 20, this will become your denominator

2. See what portion is NOT BLACK, the non black at 7 and 11, once you add these it becomes 18. 18 is now your numerator.

3. You now have the fraction 18/20 which you can simplify into 9/10

Hope this helps :)

Trig integrals. sqrt(1-cos2x)dx

Helen [10]

1 - cos 2 x = 1 - ( cos² x - sin² x ) = 1 - cos² x + sin² x = sin² x + sin² x =
= 2 sin² x
$\int { \sqrt{2sin ^{2} x} } \, dx = \sqrt{2} \int {sinx} \, dx =$
= - √2 cos x + C
