Answer:
$0.80
Step-by-step explanation:
$16.40 ÷ 20.5 = 0.80
You can check your work by doing :
20.5 cm of wire × $0.80 = $16.40
Increasing: (-4,-4)
Decreasing: (4,-2)
Answer:

Step-by-step explanation:
Given
The attached graph
Required
Equations with higher unit rate
First, calculate the unit rate of the graph

Where:


So:



For the given options.
The unit rate is the coefficient of x
So: 
Going by the above definition of unit rate.




















The unit rates grater than the graph's from small to large are:


By using basic concept of percentage we got that minimum payment on Card E is 0.77 than on Card D.
<h3>What is percentage ?</h3>
Percentage is a number or ratio expressed as a fraction of 100.
Here given that
Marilyn has two credit cards, D and E. Card D has a balance of $691. 64, and Card E has a balance of $1,014. 22. The minimum monthly payment on Card D is 3. 57% of the total balance, and the minimum monthly payment on Card E is 2. 51% of the total balance
So minimum balance of Card D is 3.57 Percentage of $ 691.64

minimum balance of Card E is 2. 51 Percentage of $1,014. 22.

Now we can see that minimum balance of Card E is 25.49-24.69=0.77 extra that on D
By using basic concept of percentage we got that minimum payment on Card E is 0.77 than on Card D.

<h3><u>Given </u><u>:</u><u>-</u></h3>
- <u>We </u><u>have </u><u>given </u><u>in </u><u>the </u><u>question </u><u>that</u><u>, </u><u> </u><u>Robin </u><u>is </u><u>flying </u><u>a </u><u>kite</u><u>. </u>
- <u>She </u><u>ties </u><u>the </u><u>5</u><u>0</u><u> </u><u>foot </u><u>kite </u><u>string </u><u>to </u><u>the </u><u>ground </u><u>.</u>
- <u>The</u><u> </u><u>kite </u><u>is </u><u>flying </u><u>at </u><u>4</u><u>0</u><u> </u><u>feet </u><u>high </u>
<h3><u>To </u><u>Find </u><u>:</u><u>-</u></h3>
- <u>We </u><u>have </u><u>to </u><u>find </u><u>the </u><u>measure </u><u>of </u><u>the </u><u>angle </u><u>the </u><u>string </u><u>forms </u><u>with </u><u>the </u><u>group </u><u>that </u><u>is </u><u>angle </u><u>of </u><u>elevation</u><u>. </u>
<h3><u>Let's </u><u>Begin </u><u>:</u><u>-</u></h3>
<u>According </u><u>to </u><u>the </u><u>given</u><u> </u><u>question</u><u>, </u>
- Hypotenuse AC ( Distance of string from the ground) = 50 ft.
- Perpendicular height AB ( Distance of the kite from the ground) = 40 ft.
<h3><u>Therefore</u><u>, </u></h3>
<u>By </u><u>using </u><u>trigonometric </u><u>ratios</u><u>,</u><u> </u>
{ 

}
<u>The </u><u>Angle </u><u>of </u><u>elevation </u><u>will </u><u>be </u>
<u>[</u><u> </u><u>The </u><u>angle </u><u>that </u><u>is </u><u>formed </u><u>between </u><u>the </u><u>line </u><u>of </u><u>sight </u><u>and </u><u>base </u><u>of </u><u>the </u><u>triangle </u><u>is </u><u>called </u><u>angle </u><u>of </u><u>elevation </u><u>]</u>





Hence, The measure of the angle the string forms with the ground is 45.83° .
