Which pair of angles are supplementary?

1 answer:

3 0

Supplementary angles are angles that add up to 180 degrees, aka one straight line. The supplementary angles here are:

1 and 2, 1 and 3, 2 and 4, 3 and 4, 5 and 6, 6 and 8, 7 and 8, and 6 and 7. Well, those are the more obvious ones. 1 and 7 are supplementary because if you envision them next to each other, you’ll see that they create a straight line. So, with that logic, 3 and 5 are supplementary because when you put them together, they create a straight line

% = (Change/Original) * 100
= (2.9/15.9) * 100
= 0.182389937 * 100
= 18.2389937
= 18%

Answer:

Problem 7) C

Problem 8) B

Step-by-step explanation:

Recall that inverse variation has the form:

$\displaystyle y=\frac{k}{x}$

Where <em>k</em> is the constant of variation.

Problem 7)

We are given that <em>y</em> = 39 when <em>x</em> = 1/3. Thus:

$\displaystyle 39=\frac{k}{{}^{1}\!/ \!{}_{3}}$

Solve for <em>k: </em>

<em /> $\displaystyle k=\frac{1}{3}(39)=13$ <em />

<em />

Hence, our equation is:

$\displaystyle y=\frac{13}{x}$

Then when <em>x</em> = 26, <em>y</em> equals:

$\displaystyle y=\frac{13}{(26)}=\frac{1}{2}$

Problem 8)

We are given that <em>y</em> = 25 when <em>x</em> = -1/5. Thus:

$\displaystyle 25=\frac{k}{-{}^{1}\!/ \!{}_{5}}$

Solve for <em>k: </em>

<em /> $\displaystyle k=-\frac{1}{5}(25)=-5$ <em />

<em />

Hence, our equation is:

$\displaystyle y=-\frac{5}{x}$
