Answer:
15 times as long
Step-by-step explanation:
6 meters/0.4 meters is 15, so it is 15 times as long.
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:
<em>The required values are a = 29°, b = 20°</em>
Step-by-step explanation:
<u>Angles and Lines</u>
The image shows two lines crossing at a point where three angles are marked: 57°, 7b-17, and 2a-1.
It can be noted that 57° and 7b-17 are linear angles whose sum is 180°:
57° + 7b - 17° = 180°
Solving for b:
7b = 180° + 17° - 57°
7b = 140°
b = 140°/7 = 20°
b = 20°
It can also be noted that 57° and 2a-1 are vertical angles (opposite angles). Vertical angles are congruent, thus:
57° = 2a - 1°
Adding 1:
2a = 58°
a = 29°
The required values are a = 29°, b = 20°
<span>For the answer to the question above, according to Weber's law, the perceptible differences are proportional to the initial perception. So, with just a 10% increase in area was perceptible, but an increase of 1-9% in the area is considered imperceptible. The 9% increase in area reflected by 200 to 218 would be perceived as the same size as before.
The <u><em>answer is 218</em></u></span>
