72 minutes
convert 8 hours to minutes ⇒ =8 × 60 = 480 minutes
15% of 480 = 0.15 × 480 = 72 minutes
<span>If you want to convert 15.1 into a fraction, you can do it like this:
15 <span>equals to 15</span>/1 <span>and </span>0.1 <span>equals to 1</span>/10
<span>The result is 15</span> 1/10.
If you want to make it a pure fraction, you have
to make one additional step:
<span>because you want to add 15/1 and 1/10, you
have to get the same denominators, so 15/1 changes to 150</span>/10.
<span>Now, you can add </span>150/10 and 1/10<span>.
The result is </span>151/10<span>.

Step-by-step explanation:
Answer:
(x-1) and (x-5)
Step-by-step explanation:
option a .......
= 3 - 3cos x - 2(1- cos^2 x)
= 2cos^2 x - 3cos x + 1
=(cos x -1)(cosx - 1/2)
now cos x = 1 or cos x= 1/2
draw a graph we get = + ve values
hence .. 0 ,180,360 and 60,240, degrees in range x<2pi
