How can you decompose the composite figure to determine its area?
Anna007 [38]

For this case the first thing you should do is observe that the diameter of the four semicircles is the same.

Therefore, we can decompose the figure as follows:


1) We draw the diameters of the four semicircles to form a square.


2) We divide the figure into a square and four semicircles


3) The total area is the sum of the area of the square, plus the area of the 4 semicircles.

Step-by-step explanation:

Mobile cost in Spain = € 352.5

Mobile cost in Japan = ¥39856

Exchange rate = £1 = €1.41

                           £1 = ¥188

                       £ 1 ------------------ € 1.41

                        x  -----------------   €352.5

                       x = (352.5 x 1) / 1.41

                       x= £250

                      £1   ------------------  ¥188

                      x    ----------------- -¥ 39856

                     x = (39856 x 1) / 188

                     x = £212

Then, it was cheaper in Japan

-9+8k=7+4k(if there is no solution,type in ''no solution'') k= Answer
Shtirlitz [24]

Answer:

k = 4

Step-by-step explanation:

-9 +8k = 7+4k

Subtract 4k from each side

-9 + 4k = 7

Add 9 to each side

4k = 16

Divide by 4

k = 4

Plug in the value you got for k:

-9 + 8(4)  ?  7 + 4(4)

-9 + 32  ?  7 + 16

23  ? 23

23 = 23
