33. Someone is reading a book that is 347 pages long. But he or she is already on page 203.Now, let’s find the percentage rate of the remaining number of pages. => 347 pages = 100% => 203 is the pages that he or she already read. Solve: => 347 – 203 = 144 pages left. Now, let’s find the percentage of 144 pages out of 347 pages => 144 / 347 = 0.41 => 0.41 * 100% = 41% Thus, he or she still need to read around 41% of the book

<u>Answer </u><u>:</u>

This figure consists of two shapes that are a rectangle and a square . We will first find the area of rectangle then the square then add them . Let's work on this together ,

  • Breadth of rectangle = 4 cm
  • Length of rectangle = 4 + 5 + 3
  • Length = 12 cm
  • Area of rectangle = 12 × 4
  • 48 cm²

Area of square ,

  • Side × Side
  • 5 × 5
  • 25 cm²

Total area of the figure ,

  • 48 + 25
  • 73 cm²

A polygon has an area of 225 square meters. If the area is tripled, how does each side length change?
krok68 [10]
Let me tell you the process so that you get to the answer
Remember first that the area of a regular polygon with x sides has  each of them a length which can be represented by y 

<span>A = 1/4 * xy^2 * Cot(180/x) </span>
<span>The purpose is to solve for y, so we get </span>
<span>y^2 = 4A/(xCot(180/x)) </span>
<span>y = √(4A/(xCot(180/x)))

The thing we need to change is A in the previous formula and with that we can use the equaation to be a constant. This could be represented by Z
</span><span>Z = √(4/(xCot(180/x)))
so
</span><span>Y = Z√A 
</span><span>If we increase area by a factor s, y increases by a factor of √x.
</span>So if you want to know the triple then you need to increase it by <span> √3 </span> <span>  </span>

I need help withy these questions.
Alekssandra [29.7K]
The little square means 90° and a straight line means 180° so 180 minus 68° minus 90° is 22° which leaves,
1) 112° and since you can flip 68° exacly the same on both sides it is a vertical angle which means
3)68.
4) 90°
