我用英文打题目,最好可以帮我用英文回答,(是数学题)
The Smithsonian Institute wants to have a model of the Statue of Liberty constructed.The Smithsonian wants the model to be 50 feet tall and 10 feet wide.The original statue is approximately 150 feet tall and 30 feet wide.(这个是信息,下面两题才是题目)
A)The torch on the original statue is approximately 15 feet tall.Use this information to find the height of the torch on the model.Show your work.
B)The gift shop at the Smithsonian wants to sell a much smaller model of the statue in its store.The gift shop calls for a model that is only 3 inches wide.Use this information to find the height of the gift shop's model.Show your work and explain your thinking.
A) as you know,the original statue is about 150 feet and the model should be 50 feet,so the proportion is 3:1,now that the torch is 15 feet,the model should be 5 feet.
B)the proportion between height and width is 5:1,so the height should be 15 inches.
再问: B)呢?
