<span>8x^2 - 2x - 1 = 0
(2x - 1)(4x + 1) = 0
2x - 1 = 0; x = 1/2
4x + 1 = 0;x = -1/4
answer

I might be incorrect. Buttt I believe this might be the answer.
The way is write it is
Minute hand length ~ 36•1.5= 54
In 45 minutes the minute hand with be at the 8 hour marker
The whole clock is equal to 360° so each hour is represented by 30°. I found that by dividing 360 by 12. (Due to how many hours are on the clock)
There is 9hour markers between 11 and 8.
So there’s a 270° distance between the minute hand and 45 minutes.
I found this by timing 9 by 30
Answer:
the answer is 28 degrees
Step-by-step explanation:
all you do is subtract 180-128 since this is a supplementary angle and not a complimentary one.
Answer:
C.
Step-by-step explanation:
The pythagorean theorem shows a^2+b^2=c^2.
a=8, b=15, c= the unknown distance
8^2+15^2=c^2
20 + 0.08x = 16 + 0.13x
20 - 16 = 0.13x - 0.08x
4 = 0.05x
x = 80 minutes
20 + 0.08(80) = 16 + 0.13(80)
20 + 6.4 = 16 + 10.4
$26.40
