Swimsuit discounted 65% on sale for $20.30
tigry1 [53]
Hello there!

Knowing that you have a swimsuit of an original price of $20.30 that is discounted 65%, you can find the price of the swimsuit after the discount by first finding 65% of your original price. 

To find 65% of your original price, multiply 65% to 20.30:
0.65*20.30
=13.195

Now, subtract this amount from your original price:
20.30-13.195
=7.105

Finally, round to the nearest cent to get $7.11 dollars as your final answer.

Hope this helps and have a marvelous day! :)

Find the center, vertices, and foci for the ellipse 25x^2 + 64y^2 = 1600
Alisiya [41]

Answer:

The answer to your question is below

Step-by-step explanation:

Data

Equation               25x² + 64y² = 1600

Process

1.- Divide all the equation by 1600

                             25x²/1600 + 64y²/ 1600 = 1600/1600

-Simplify

                              x²/64 + y²/ 25 = 1

2.- Equation of a horizontal ellipse

                             \frac{x^{2} }{a^{2}} + \frac{y^{2}}{b^{2}} = 1

3.- Find a, b and c

    a² = 64             a = 8

    b² = 25             b = 5

-Calculate c with the Pythagorean theorem

                   a² = b² + c²

-Solve for c

                   c² = a² - b²

-Substitution

                   c² = 8² - 5²

-Simplification

                  c² = 64 - 25

                  c² = 39

-Result

                  c = √13

4.- Find the center

          C = (0, 0)

5.- Find the vertices

          V1 = (-8, 0)     V2 = (8, 0)

6.- Find the foci

          F1 = (-√13, 0)   F2 = (√13, 0)

Un paese contava 12000 abitanti all'inizio del 2007 durante l'anno i nati sono 1,7 % del totale degli abitanti e morti sono 2% c
grandymaker [24]

Step-by-step explanation:

12000 abitanti all'inizio del 2007

nati: 1.7% × 12000 = 204

morti: 2% × 12000 = 240

popolazione all'inizio del 2008: 12000 + 204 - 240 = 11964
