Answer: B
Step-by-step explanation:
The Black Plague or Black Death was spread from Asia to Europe through trading barges or ships. Since a lot of people in Asia contracted the plague, it was natural the rats on the ship also carried the disease. Where the ships landed, rats or their fleas hiding on humans would come with the travelers. While European countries were fighting wars during the plague, it mostly halted because of the sharply increasing deaths from the disease. Religion was used more for trying to cure the Black Death, and ironically there was more food and land for the survivors since there were less mouths to feed.
Answer:105.2
Step-by-step explanation:
Answer: 12 friends.
Step-by-step explanation:
the data we have is:
Mei Su had 80 coins.
She gave the coins to her friends, in such a way that every friend got a different number of coins, then we have that:
The maximum number of friends that could have coins is when:
friend 1 got 1 coin
friend 2 got 2 coins
friend 3 got 3 coins
friend N got N coins
in such a way that:
(1 + 2 + 3 + ... + N) ≥ 79
I use 79 because "she gave most of the coins", not all.
We want to find the maximum possible N.
Then let's calculate:
1 + 2 + 3 + 4 + 5 = 15
15 + 6 + 7 + 8 + 9 + 10 = 55
now we are close, lets add by one number:
55 + 11 = 66
66 + 12 = 78
now, we can not add more because we will have a number larger than 80.
Then we have N = 12
This means that the maximum number of friends is 12.
