Leg <em>a</em> = <em>x</em>

Leg <em>b</em> = 5

Hypotenuse <em>c</em> = 8

<u>Step 2: Solve for </u><em><u>x</u></em>

  1. Substitute [PT]:                     x² + 5² = 8²
  2. Isolate <em>x</em> term:                       x² = 8² - 5²
  3. Exponents:                            x² = 64 - 25
  4. Subtract:                               x² = 39

A person has 100 notes of Rs. 10 and Rs. 20 each. He went to a shop and bought items for Rs. 220. In how many ways can he pay th
Alekssandra [29.7K]

There are 12 ways he can pay this amount using the notes he has the answer is 12.

<h3>What are permutation and combination?</h3>

A permutation is the number of different ways a set can be organized; order matters in permutations, but not in combinations.

Let x be the number of Rs10 notes and y be the Rs20 note

10x + 20y = 220

The whole number of x and y which satisfy the above equation:

x = 0, y =11

x = 2, y =10

x = 4, y =9

x = 6, y =8

x = 8, y =7

x = 10, y =6

x = 12, y =5

x = 14, y =4

x = 16, y =3

x = 18, y =2

x = 20, y =1

x = 22, y =0

Total number of ways = 12

Thus, there are 12 ways he can pay this amount using the notes he has the answer is 12.
