She would save 54.45 because addding them up individually before the plan would cost 184.49 and to find the difference all you have to do is subtract 184.49-129.99 and that would tell you how much she saved
Out of 30 students, if you add up 11, 16, and 3, you get 30. Which means there is no remainder and there are no students that did not like either sport.
Hello from MrBillDoesMath!
Answer:
283 degrees
Discussion:
A circle has 360 diverges so summing up all the angles gives:
360 = (7y - 7) + (20y-11) + (4y + 6) => combine like terms
360 = (7y + 20y + 4y) + (-7 - 11 + 6) =>
360 = 31y - 12 => add 12 to both sides
372 = 31y =>
y = 372/31 = 12
measure arc ABC =
360 - measure arc (7y-7) =
360 - (7*12-7) =
360 - (77) = 283
Thank you,

4 binary digits have 2^4 = 16 combinations.
The combinations with exactly one 1 are: 1000, 0100, 0010 and 0001. So 4 out of 16 codes have exactly one 1.
The chances of that are 4/16 = 1/4.
16/99
8/9
2/9
do the last three have a decimal in the start?
