Answer:
<u>A. 52 green beads; 39 yellow beads</u>
Step-by-step explanation:
See the attachment. If we take the ratios of 4, 2 , and 3, they add to 9. The
Green (G), Blue (B), and Yellow (Y) will have 4/9, 2/9 and 3/9 each of the total beads, 117.
G: 52 Beads
B: 26 Beads
Y: 39 Beads
Answer:
<h2>The hurricane's speed was 200kmph</h2>
at average
Step-by-step explanation:
The way how we can find this is <em>simple</em>. If we look at the graph, we see that in 1 hour, the hurricane traveled at a constant rate of 200kmph
Hence, the hurricane's average speed was 200kmph
Answer:
126 different symbols can be represented in Morse code
Step-by-step explanation:
We need to sum up the number of sequences using one single place, two places, three places, four places and so on until sequences of six places (dots and dashes).
For each case we use the fundamental counting principle.
For one single place we may have 2 possible sequences (a dash or a dot)
For two places (example: .. or ._) we may have 2*2 sequences, since each place may be filled with either dash or dot (2 possible ways) and then we multiply the ways each place can be filled, thus
Similarly, for three places we may have 2*2*2 sequences, thus
For four places we may have 2*2*2*2 sequences, thus
And so on.
So, notice the total up to arrangements of six symbols, is:
Answer:
first statement
Step-by-step explanation:
∠ 2 = ∠ 6 ( Alternate angles )
∠ 1 = ∠ 5 ( Alternate angles )
Thus Δ ABC ~ Δ EDC by the AA postulate
