Intensity=k/(distance)² where k is a constant
8000=k/2²
8000=k/4
k=32000
If distance is 11 miles, Intensity=k/11²
=32000/121
=264.46units
≈264units
Answer:
C.
Step-by-step explanation:
Integers are rational numbers.
A + B = m/q + n/p = (mp + nq)/pq
The range is the biggest number minus the smallest so 26 and 45. The answer is 19, C
Answer:
18
Step-by-step explanation:
10 +3 =13 +5 =18
so that is how you get the answer 18 it's simple really
Probability of a rock song would be 2/7 ( 2 rock songs out of 7 total songs)
Probability of a country song after that would be 3/6 (3 country songs out of 6 songs left) this can be reduced to 1/2
The probability of both = 2/7 x 1/2 = 2/14 = 1/7
