The answer is 21 because if you subtract 17 from 17 and 38 you get 21. Z=21.
Morse code is essentially the same as binary. That is, there are two "digits", a dot or a dash.
There are 26 letters in the English alphabet. Clearly, we can't just use one dot or dash, since that could only encode 2 letters at the most. We can't use two symbols because that could only encode 4 letters at the most. Similarly, 3 symbols means

letters at most.
We have to select the smallest power of 2 that exceeds or is equal to 26. In this case,

, so we would have to use up to 5 symbols to encode each letter in the alphabet.
Answer:
<u>9 inches are 1/4 or 0.25 yards and we used inches in the numerator and yards in the denominator for our ratio.</u>
Step-by-step explanation:
1. Let's review the information given to us to answer the question correctly:
1 yard = 36 inches
2. In converting 9 inches to yards, what unit (omit the number) would you place in the numerator of your ratio?
This is the ratio for calculating the answer:
36/1 = 9/x
36x = 9 *1
36x = 9
x = 9/36
x = 1/4 or 0.25 yards
<u>9 inches are 1/4 or 0.25 yards and we used inches in the numerator and yards in the denominator for our ratio.</u>
You need to multiply the base by the height.
Six hundred ninty three thousand, five thousand six hundred ninty nine
Three hundred fourty thousand two thousand and eighty nine
I’m confused on the comma for the last 2?
