Answer:
16 rolls of ribon
Step-by-step explanation:
C = Dπ
d = r x 2
d = 100 x 2
d = 200
C = 200 x 3.14
C = 628
628 / 40 = 15.7
she should buy 16 rolls
If you flip over the x-axis A' would be (1, -1) (just change the sign on the x)
Then rotate 180 reverse the points to get A'' at (-1, 1)
Answer: the last three statements are true.
Step-by-step explanation:
Just look and compare the 2 trapezoid. They are the same.
the gcf of 40 and 60 is 2.
-steps:
40: 1, 2, 4, 5, 8, 10, 20, and 40
60: 1, 2, 3, 6, 11, 22, 33, and 66
in the factors of both numbers only number 2 is the common number, so 2 is the gcf of 40 and 66
