What does k equal if <br>485= 1/((k)(5.99x10^-3))
Verizon [17]
k\ne 0

485=\frac{1}{(k)(5.99*10^{-3})}\\\\ \frac{485}{1}= \frac{1}{0.00599k}\\\\ 485*0.00599k=1\\\\ k=\frac{1}{485*0.00599}\\\\k\approx 0.3442

The product of two consecutive room numbers is 420. find the room numbers.
marissa [1.9K]
Hello : 
the  consecutive room numbers are : n , n+1
n(n+1) =420
n²+n -420 = 0 
the discriminant delta = b² - 4ac       ( a = 1  and b =  1  and   c = - 420
delta = (1)²-4(1)(-420) =1681= 41²
n = (-1 -41)/2    ( refused negatif number)
or 
n = (-1+41)/2 =20
<span> the room numbers.are : 20  , 21</span>
