Target has a 42" HDTV that sells for $1,250 and is on sale for 15% off. After a sales tax of 6.5%, what is the final cost for the fancy TV? Round the final answer to the nearest penny.

$ 1,131.56

Step-by-step explanation:

1,250x85%=1,062.50

1,062.50x6.5=69.06

1062.50+69.06=1,131.56

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m
