The cost of a dinner is divided equally among 12 diners.Each diner pays $12.50 for his or her portion. what was the cost of the
dinner?
2 answers:
$150
Answer: $150
Step-by-step explanation:
We can simplify 12.50 to 12.5, because the zero is behind the decimal point, and has nothing after it.
We multiply 12.5 (the cost of each portion) by 12 (the amount of portions) to get the total cost. If you are allowed to use a calculator you can just plug in the numbers, as so:
12.5 x 12 = 150
If not, and you need to show work, It'll look like the image I attached.
If you're unsure, you can use division to check your answer.

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:
