10 3/5 = 10 6/10 and 11 1/2 = 11 5/10
Answer:
1: 30 degrees
Step-by-step explanation:
In Physics, we have the law of reflection. This law states that when light rays hit the smooth surface of mirror or any smooth polished surface, the angle of incidence is equivalent to the angle of reflection.
Mathematically:
Angle of incidence = Angle of reflection
From the above question, the angle of incidence is on a smooth plane mirror = 30°
Since:
Angle of incidence = Angle of reflection
30° = 30°
Therefore, based on the law of reflection, the Angle of reflection = 30°
The answer is C.
The y-intercept is 1, the slope is -1/3, and the shaded area is under the graph because y is LESS than -x/3 + 1.
Answer:
1/12 + 3/12 = 4/12 (or 1/3)
Step-by-step explanation:
we want to express
1/12 + 1/4 as 1/12 + something / 12
1/12 + 1/4 = 1/12 + something/12
we already have the 1/12 part, so we're left with
1/4 = something / 12
first, we can calculate (denominator we want) / (denominator we have) = 12/4 = 3
then, we want to multiply our current value (1/4) by our result of the multiplication divided by itself.
3/3 = 1
1/4 = 1/4 * 1 = 1/4 * 3/3 = 3/12
thus, our second value is 3/12
we then have 1/12 + 3/12
if we have the same denominators, we can simply add the numerators up
1/12 + 3/12 = (1+3)/12 = 4/12
