Does the construction demonstrate how to bisect a segment correctly by hand?
Yes, the compass was kept at the same width to create the arcs for points C and D.
Yes; a straightedge was used to create segment CD.
O No: the compass was not kept at the same width to create the arcs for points C and D.
O No; a straightedge was used to create segment CD.

i would be happy to . most people on would also love to i'm sure. if you just want someone who has done algebra before and want a little more personal relationship than just begging strangers for , i can certainly be of service. i do have college myself so i might not be 24/7.

b, i believe, but not sure.

step-by-step explanation:

ending amount = beginning amount / (2^n)

where "n" = number of half-lives (or elapsed time / half-life)

ending amount = 50 mg / (2 ^10 / 5.3)

ending amount = 50 mg / (2 ^ 1.8867924528)

ending amount = 50 m / 3.6981210597

ending amount = 13.5203794557 mg

or about 13.5 mg remain
