Percent means literally per one-hundred...

p/100=13/20 multiply both sides by 100

p=1300/20

p=65%

The angles of a pentagon are in ratio
ivanzaharov [21]

Answer:

  216°

Step-by-step explanation:

The ratio of the sum of smallest and largest to the total of all angles is ...

  (9 +15)/(9 +10 +12 +14 +15) = 24/60 = 0.4

__

The total of all angles in an n-gon is 180°(n -2), so the total of all angles in a pentagon is ...

  180°(5 -2) = 540°

Then the sum of smallest and largest angles is ...

  0.4(540°) = 216°

Answer:  The answer is NOT Letter B

C. y = 1/4x^2

Step-by-step explanation:  I used math.way

A.    y = x^2  = Rewrite in vertex form and use this form to find the vertex ( h , k ) .  ( 0 , 0 )    =Find the vertex form.  y = x 2

B.    y = 1/4x^2 + 1  = Rewrite in vertex form and use this form to find the vertex  ( h , k ) .   ( 0 , 1 )    =Find the vertex form.   y = 1 /4 ⋅ ( x + 0 ) 2 + 1

C.    y = 1/4x^2  = Rewrite in vertex form and use this form to find the vertex  ( h , k ) .   ( 0 , 0 )  =Find the vertex form.   y = 1 /4 x 2

D.    y = 1/4( x - 2)^2 + 1  = Rewrite in vertex form and use this form to find the vertex  ( h , k ) .   ( 2 , 1 )    = Already in vertex form.   y = 1 /4 ( x − 2 ) 2 + 1

The areas of the squares adjacent to two sides of a right triangle are shown below. What is the area of the squares adjacent to
Gelneren [198K]

Answer:

<em>11 square units</em>

Step-by-step explanation:

Find the diagram attached

First we need to find the side length of the square with known areas.

Area of a square = L²

L is the side length of the square

For the green square

44 = L²

Lg = √44

For the purple square

Ap = Lp²

33 = Lp²

Lp = √33

Get the length (L) of the unknown square using pythagoras theorem;

Lg² = L²+Lp²

(√44)² = L²+(√33)²

44 = L²+33

L² = 44-33

L² = 11

Since Al = L²

<em>Hence the area of the square adjacent to the third side of the triangle is 11 square units</em>
