A washer and a dryer cost $562 combined. The washer costs $88 less than the dryer. What is the cost of the dryer?
Yanka [14]

Answer:

<em>Let the dryer cost x.</em>

<em>Then, the washer costs (x+87)</em>

<em> </em>

<em>Together, they cost  (x) + (x+87) = 787</em>

<em>         2x+87 = 787</em>

<em>            2x = 700           [subtract 97 from both sides]</em>

<em>             x = 350             [divide both sides by 2]</em>

<em> </em>

<em>The dryer cost $350.</em>

<em> </em>

<em>Check:   The washer cost $437.  Together, they cost $787  [good to check, right?]</em>

<em></em>

<em><u>Hope this helps...</u></em>

A certain virus is dying off at a rate of 18% per hour. Initially there were
djyliett [7]

Answer:

3 strain would still alive after 48 hours

Step-by-step explanation:

Initial population of virus = 40000 grams

A certain virus is dying off at a rate of 18% per hour.

We are supposed to find  how much of the  strain would still be alive after 48 hours

Formula : N(t)=N_0(1-r)^t

N_0=Initial population

N(t)= Population after t hours

r = rate of decrease = 18% = 0.18

t = time = 48 hours

So,the  strain would still be alive after 48 hours=40000(1-0.18)^{48}=2.91 \sim 3

Hence 3 strain would still alive after 48 hours
