A mother decides to teach her son about a letter each week. She will choose a letter from the name of the day. For example, on Saturday she might teach about the letter S or the letter U, but not the letter M.

1. What letters are possible to teach using this method? (There are 15.)
2.What 4 letters that can't be taught using this method?
3. On Tuesday, the mother writes the word on a piece of paper and cuts it up so each letter is on a separate piece of paper. She mixes up the papers and picks one. What is the probability that she will choose the with the letter Y? Explain.

127

whether it's diameter, or radius, i believe if i remember correctly from school, every amount has to always add up to 180. so if you take 53, and starting adding, long story short, taking 127 and adding it to 53, gives you 180.

139 divided by a number

step-by-step explanation:

i think its a.

hope this

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
