The current in a simple electric circuit varies inversely as the resistance. If the current is 20amps when the resistance is 5 o
hms, find the current when the resistance is 8 ohms
1 answer:
Answer:
0.5amps
Step-by-step explanation:
I is inversely proportional to resistance
I = k/R
k = I/ R
k = 20/5
k = 4
This means that, I = 4/R
So, when R = 8ohms,
I = 4/8
=0.5amps

Answer:
n = 19/18
Step-by-step explanation:
Given:
11/6 = n + 7/9
Find n
11/6 = n + 7/9
Subtract 7/9 from both sides of the equation
11/6 - 7/9 = n + 7/9 - 7/9
11/6 - 7/9 = n
(99-42) / 54 = n
n = 57/54
n = 19/18
Answer is -5.
Explanation- Since t equals 0. You put 0 in place of every t.
0(2)- 2(0)- 5 =
0-0-5= -5
Answer:
35 interviews
Step-by-step explanation:
1. Find the rate
21/3 = 7 people an hour
2. Find how much she can do in 2 hours
7 x 2 = 14 interviews
3. Add the 2 numbers
21 + 14 = 35 interviews
