Answer:
BCA = 65
Step-by-step explanation:
Answer:
it times 4
Step-by-step explanation:
so each time you would multipley by 4
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
The third answer
1 quarter, 6 dimes, 1 nickel, 7 pennies
