A little Algebra, and we're home free!
We are given R = 20 and r2 = 75. We need to find r1.
The formula is 1/R = 1/r1 + 1/r2. Plug-in:
1/20 = 1/r1 + 1/75
1/20 - 1/75 = 1/r1
0.0366 = 1/r1
r1 = 1/0.03666
r1 = 27.272
Our answer is r1 = 27 ohms.
Answer:
I think the answer is 20....I'm so sorry if that is wrong :[
g=0.04 times d
Step-by-step explanation:
if you multiply 0.04 with every number under the d column then you’ll get the outcome of each number under g
Answer:
x > -1
Step-by-step explanation:





* Remember that,
if you have a negative sign (-) infront of the x you have to change the direction of the inequality sign.
