The concept to answer this question can be bought from physics.
The Snell's law of refraction says that, the ration of sine of angle of incidence to the the sine of angle of refraction is constant for a given media.
This means;
(sinθ1)/(sinθ2) = k
Where θ1 = angle of incidence and
θ2 = angle of refraction
k = constant
(sinθ1)/(sinθ2) = k
sinθ2 = k/sinθ1
= k/sin25
= k/0.422618261
= 2.366k
The angle of refraction, θ2 = anti-sin(2.366k)
Answer:
12
Step-by-step explanation:
12 = 2 digits
1 + 2 = 3
1 < 2
Answer:
no.
Step-by-step explanation:
The survey has too small of a group to be random.
10. >, because there are 16oz in a lb
11. =, because there are 36 inches in a yd.
12. 13qts, because you multiply the 16 oz by the 26 mugs. Then you can divide by 32 since that's how many oz are in a qt
