Answer:

Similarity statement is a little mixed up.

Step-by-step explanation:

Your similarity statement is a little off. The order in the statement DOES MATTER.  For example angle E corresponds with angle V or T (∠V≅∠T). These would be correct...

  • CDEF similar TUVS
  • CDEF similar TSVU
  • CDEF similar VSTU
  • CDEF similar VUTS

                    ...**

  • FEDC similar UTSV
  • FEDC similar STUV**

**There are a lot but the first letter of the first polygon corresponds with the first letter of the second polygon and so on. That is the only way this statement is true. There are about a 96 different combinations for this so any one would work.

The similarity ratio is the same thing as asking "what value would make the first polygon congruent to the second"? In this case 1(x) = 4, x = 4. Therefore the ratio is 4, or 4/1 (if asked can also be written as 4:1. THE ORDER IS ALSO VERY IMPORTANT.

Answer:

a) $525 CAD

b) $168.30 per day

c)  $38.05

Step-by-step explanation:

a)  <u> 1 USD </u> = <u>  500  </u>

    1.05CAD      x

cross-multiply:  x = $525 CAD

b) 504.90 / 3 = 168.30 per day

c)  <u> 1 USD </u> = <u>   x   </u>

    1.05CAD   39.95

cross-multiply: 1.05x = 39.95

x = 39.95 / 1.05

x = $38.05 USD

A circular swimming pool has diameter 60 feet and is centered in a fenced-in square region measuring 80 feet by 80 feet. a concr
borishaifa [10]
If I read the question correctly, the information about the 80x80 fencing and the grass region are all irrelevant information. 

In order to find the area of the side walk we are going to use the formula A=pi(r^2) where r = the radius. The diameter of the pool is 60 feet and the the sidewalk is 5 feet bigger all around meaning we had 5 feet to both sides of this 60 feet giving you an overall diameter of 70 feet (or 60 + 5*2). To find the radius take half of the diameter. 70/2 = 35. 

Now we plug in 35 to the equation. A = Pi(35^2) = 1225pi. Leave your answer like this as we are not finished and will need to round at the end for an accurate answer. This is NOT the end, that number is the area of the sidewalk AND the pool.

The sidewalk is not a full circle, just a border so we now have to find the area of the actual pool and subtract it from this 1225pi for the sidewalk's area. Same formula, Area = pi(r^2). The diameter of the pool is 60 meaning the radius is 30 (or 60/2). Plug into the equation, pi(30^2) = 900pi.

Now do 1225pi - 900pi to get 325pi. Break out your calculator and hit the approximation button. 325pi is approximately 1021.018 if rounded to 3 decimal places.

The area of the 5-foot wide sidewalk encircling the pool is approximately 1021.018 square feet.
