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.
I’m not sure but u multiply 2.5 by 3.8 to get amount she has to pay for GB. Since it free texts so 2.5 • 3.8 = $9.5 plus $15 which give $24.5
I could be wrong..
She will knit (1/2)*(3/5) = 3/10 of the scarf today.
