The <em><u>correct answer</u></em> is:
They had no placeholding zero.
Explanation:
Our numbering system is one of few known to have a numeral for zero. Mayans did; however, theirs never traveled the world. Babylonians were thought to have a mark for nothing, but it was more for punctuation than numerals. Neither the Romans nor the Egyptians had a number for 0 either.
Zero is key to our system of numbering, as it helps us hold place as well as representing nothing. Without it, it is easier to represent problems in words.
The answer to the question
Answer:
24 individuals
Step-by-step explanation:
Since we are given the actual costs as well as the final total then we can calculate the total number of people that attended the party by doing the following. We first subtract the fixed cost of $120 by the total cost of the party, and then we divide the remainder by the cost per person, which would give us the number of people who attended (x) ...
($480 - $120) / $15 = x
$360 / $15 = x
24 = x
Finally, we can see that a total number of 24 individuals attended the party
Answer:
20.5 : 61.5
Step-by-step explanation:
1:3
1 + 3 = 4
82 ÷ 4 = 20.5
ratio of 1:3
1 × 20.5 = 20.5
3 × 20.5 = 61.5
20.5 : 61.5
