A tennis shoes regularly sells for $20.00. The store advertises a 15% discount. What is the sale price of the necklace in dollars?

Shoes with discount = $17

Necklace = Price * 0.85

Step-by-step explanation:

-If the tennis shoes store sells other things than shoes-

Shoes = $20.00

Discount = 15%

*Price expressed as a percentage*

Price without discount = 100%

Price after discount = 100% - 15%

Price after discount = 85%

*Normal price*

Price without discount = 20

Price after discount = 20 * 0.85

Price after discount = 17

a. -0.3 > -0.33

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl
