Ray has enough money to purchase the t-shirt and the Jordans on sale.

Step-by-step explanation:

Regular cost of Jordans  =$

Cost of Jordan's T-shirt = $

Total cost  = $ + $ = $

Discount offered on purchase of T-shirt = $

Price after discount = $ - $ =$

Sales tax = %

Tax to be added = $ = $

Final price = $ + $ =$

Amount Ray has = $

∴ Ray has enough money to purchase the t-shirt and the Jordans on sale.

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

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.
