The distance between two towns on a map measures 4.8cm. If the scale of the map is 1:250000 what would the actual distance be?
Archy [21]

The actual distance will be 12 km.

<u>Explanation</u>:

The scale of the map is 1:250000

1 cm in the map represents 250000 cm.

250000cm=2500 m=2.5 km

the measurement in the map is 4.8 cm

since 1 cm represents 250000 cm or 2.5 km

The actual distance represented by 4.8 cm on the map = 4.8*250000 cm =1,200,000 cm=12000 m=12 km

Who inspired the French people with a sense of nationalism during the Hundred Years’ War? A. Gutenberg B. Charlemagne C. Martin
lara [203]

Answer:

<h2>D. Joan of Arc</h2>

Explanation:

Joan of Arc was a French peasant who claimed she'd had visions of saints and an angel that told her to help restore France from domination by the English.  

Joan of Arc came to the scene at a critical time in 1429.  The northern half of France was essentially under the control of the English.  There was contention over who was truly the French king after Charles VI had died in 1422.  His son, the prince Charles, was a claimant to the throne. But the English contended their boy king, Henry VI, should rule over France.

In January 1429, Joan (age 17) came to the court of the prince, Charles, and convinced him of her mission from God.  Within a few months, she had rallied the people of France and helped to break the control of the English over large sections of French territory.  She ultimately was captured by a group of French nobles who were allied with the English, was handed over to the English, and was burned at the stake (in 1431).  But she had done much to unite the French people around a sense of common patriotism and national aspirations.
