Answer:
i don't know sorry . and study well to make your future good
You would add 4.40 to 55.50 to get 59.90. because the sales tax is 8% which is 0.08 cents and multiply that by 55 to get 4.40
I wrote down the answer cuz it’s just easier to read that way:)
The answer would be n=37 because…
40+n=77
subtract 40 on both sides, cancelling it out on the left side and 77-40=37 so:
n=37
Let A = arc length of circle
A = 2πr•(degree/360°)
A = 2π(12)(150°/360°)
A = 24π(150°/360°)
Calculate the right side to find A and you're done. Take it from here.
