Answer:

Step-by-step explanation:
The perimeter of a polygon is simply sum of the lengths of all sides of the polygon.
Therefore, we can find this polygon's perimeter by adding up the length of each of its sides:

Since there is a lot to keep track of, I'd recommend picking any side and moving clockwise/counter-clockwise until you get all sides.
Answer: $623
Step-by-step explanation:
calculation of Finance charge due on October 14
(+) $ 559 due on sep 14, $ 559 * (19.5*31) / (100 * 365) = $ 9.20
(+) purchase $ 289 on sep 19, $ 289 * (19.5*26 ) / (100 * 365) = $ 2.42
(+) finance charge on sep 28, $ 18 *(19.5*17 ) / (100 * 365) = $ 0.17
(-) Repayment on 25 sep , $ 250 * (19.5*20 ) / (100 * 365) = (2.745)
Total finance charges from 14 sep to 14 oct = $ 9.7= appr. 10
Amount due on 14 October = $559+$289+$15+$11.855- $250
= $ 623
H= 12.4
I assume this is a rectangular prism. the formula is V=l*w*h
plug-in the known values
<span>V=3758.75 W=24.25 L=12.5
</span><span>3758.75 =24.25*12.5*H multiply terms
</span><span>3758.75=303.125H divide both sides by 303.125
12.4=H</span>
W +Y =5000
20/100 x W= 30/100 X Y
W/5=3Y/10
10W=15Y
W=15Y/10=3Y/2
3Y/2+Y=5000
3Y+2Y=10,000
5Y=10,000
Y=2000
AND HENCE W=3 x2000/2=3000
Answer:
(x, y) = (3, 5)
Step-by-step explanation:

Solving by elimination here again, there are 2 good options available. Either multiply the whole bottom equation by -1 to cancel the x, or by 2 to cancel the y. I'll do the latter:

Add from top to bottom:

Now, with the value of x, solve for y in either of the equations. I'll choose the second one here:

(x, y) = (3, 5)
