Step-by-step explanation:
Here is a helpful method I taught my students in my mini lesson...
For you to remember, 22= 4, and 32= 9. Hence the answer to the root of 8 lies between the numbers 2 and 3. However, since the square of 3 equals to 9 which is larger than 8, the root 8 value lies in between the number 2.8 and 2.9.
The 3 represents a whole number.
The .62 is representing 62% of a number, and the three is the whole number.

A is c=75 B is a=120 C is b= square root of 75 and D= square root of 245
Let k be a constant of proportionality. We can use the given information to write two equations:
24 = k/5 and 12 = k/10.
Solving for k gives k = 120 in both cases.
Let R be the unknown resistance when the current is 15 amperes:
15 = 120/R.
R = 120/15
R = 8 ohms.
