The formula for the light bend would be n1*sin i= n2 * sin r
If you use "sin (90-x)= cos x" principle, you can change the sin in the equation into
n1*sin i= n2 * sin r
n1 * cos a= n2 * cos b
n2/n1= cos a/ cos b
Assuming the n constant is the ratio of the glass compared to water then the answer would be: cos a/ cos b
Just multiply it so multiply 59.89 x 4 and then for number 8 multiply 88.70 x 4
Answer:
there are four significant figures
Step-by-step explanation:
zeros to the right of a non zero digit are ambiguous
A gardener has 8 pounds of fertilizer. He packs the fertilizer into 5/8 pound bags. What is the maximum number of 5/8 pound bags he can pack?
so first you multiply 8 pounds times 5 from 5/8 which is 40/8 pounds bags
now how many 8s can fit in 40
40 divided by 8 =5
so he can pack 5 maximum bags
