Find the selling price of each item.<br> 57) Original price of a puppy: 339.50<br> Discount: 55
densk [106]

Answer:

The selling price of the puppy is $284.50.

Step-by-step explanation:

In the present case, the puppy's original selling price is $ 339.50. At this price a discount of $ 55 is made, that is, that amount is subtracted from the original price, modifying the sale price.

Therefore, since 339.50 - 55 results in 284.50, the puppy's sale price goes from $ 339.50 to $ 284.50, taking the aforementioned discount.

Jess and Wes used to race each other when they were younger. Jess could cover 8
marshall27 [118]

Answer:

160 meters

Step-by-step explanation:

Let call dj  distance run by  Jess    and   dw  distance run by Wes

By Jess courtesy Wes will be  60 meters ahead of Jess

Let call t the time in which both runners are at the same point, which in fact is when both distances are equal

dj  =  8 m/sec * t        and    dw  =  60  +  5 m/sec * t

Then we make  dj = dw

8*t  =  60 + 5*t

3*t  =  60

t = 20 sec

Now passed 20 sec  dj   =   8 * 20   = 160 m

and   dw = 60 + 5*20   dw  =  160 m

Which of the following represents the translation of M (8,-2) along vector&lt;-5, 1 &gt; and its reflection
Ulleksa [173]

Step-by-step explanation:

M(8.-2), M'(x,y) , $$\overrightarrow{v} =(-5,1)

$$\overrightarrow{MM'} = $$\overrightarrow{v}

--> x - 8 = -5 --> x= 3

---> y+2 = 1 --> y =-1

so M'(3,-1) and its reflection y-axis is (-3,-1)
