55.27 is the same as 55 ____' 12".
choli [55]
<span><span>27100</span>(60)=<span>815</span>=16<span>15</span></span> The 16 is how many minutes you have. If you were not given the seconds, we would have to say that we have a remainder of (1/5) of a minute. Since 1 minute is (1/60), one-fifth of that is (1/300). Now we would need to see how many seconds that gives us. 1 second is (1/3600) of a degree, so we would need to divide (1/300) by (1/3600). Doing this gives us: <span><span><span>1300</span>÷<span>13600</span>=<span>1300</span>(3600)=12</span></span>

Please help i have no idea what are the excluded values to the equation y = 5 / (x^2 - 7x 10)?
Kryger [21]
Hello,

The excluded values are the roots of the denominator.

x²-7x+10=x²-2x-5x+10=x(x-2)-5(x-2)=(x-2)(x-5)

Roots of the denominator are x=2 and x=5
