Perpendicular lines form 90 degree angles.
Letter C.
49 is the answer cjfuvvryssokskdoxofo
next three are n+2, n+4, and n+6
four consecutive odd have sum 56
n + n+2 + n+4 + n+6 = 56
4n + 12 = 56
4n = 44
n = 11
the numbers are 11, 13, 15, and 17
Answer:
20 X 40 = 800 (split into 2 fourths) = 40
Step-by-step explanation
20 x 40 = 800;
For 2 necklaces she can split 800 into fourths.
800 - 40 = 80. (1 fourth)
80 - 40 = 40 (2 fourths)
40 - 40 = 0 (3 fourths)
She could split 800 into 2 fourths to get a number more than 0 and less then 42.
The best estimate of rounding 42 is 40. Because 40 is closer to 42.
