Answer & Step-by-step explanation:
For this problem, we have to find the equations that have a value of 10 for the variable y. Immediately, we can eliminate some answers. We can eliminate A, D, and E because they all have a different value for the variable y. So, that leaves us with answer choices B and C.
In order to check to see if we are correct, let's plug in 10 for the y in answer choices B and C.
<u>B: </u>
8 = 18 - y
8 = 18 - 10
8 = 8
<u>C:</u>
60 = 6y
60 = 6(10)
60 = 60
So, as you can see, we are correct and we have successfully found the correct answer to the given problem.

Answer:
1/250 W/m² or 0.004 W/m² or 4 mW/m²
Step-by-step explanation:
The cargo worker is (50 m)/(1 m) = 50 times the reference distance. The intensity varies as the inverse of the square of the distance, so will be ...
(1/50)²×(10 W/m²) = 10/2500 W/m² = 1/250 W/m²
This might be more conveniently written as 4 mW/m².
5 x 3 = 15
30 x 3 = 90
15+90=105
so that person paid $105 for that day
