All you need to do is put 45 over 100 to make it 45/100, then simplify down until you get your answer. The answer is 9/20 though. There may be better ways, but that's how I do it.

If the equation y² - (K-<br>2y + 2k +1 = 0<br>with equal roots find the value of k​
777dan777 [17]

Answer:

y² - (K-  2)y + 2k +1 = 0

equal roots means D=0

D= b^2 - 4ac

a=1, b= (k-2), c= 2k+1

so,

(k-2)^2 - 4(1)(2k+1) = 0

=> k^2 +4 - 8k -4 = 0

=> k^2 -8k = 0

=> k^2 = 8k

=> k= 8k/k

=> k = 8

Therefore the answer is k= 8

Hope it helps........

Keisha wants to meet for 90 minutes so far she has read 30% of her goal how much longer does she need to read to reach her goal
sladkih [1.3K]

Answer:

30% of 90             

30% x 90              

30/100 =3/10              

3/10 x 90 = 270/10          

270 = 27     

90 - 27 = 63          

Keisha has to read 63 more minutes to reach her goal.
