Re: [計量] PP-T1-DS-214
※ 引述《rnrn ()》之銘言：
: The cost of a square slab is proportional to its thickness and also
: proportional to the square of its length. What is the cost of a square slab
: that is 3 meters long and 0.1 meter thick?
正方形木板的價錢是跟他的厚度成比例的,也跟他的長度成比例.
問一個長3公尺.厚0.1公尺的多少錢
: (1) The cost of a square slab that is 2 meters long and 0.2 meter thick is
: $160 more than the cost of a square slab that is 2 meters long and 0.1 meter
: thick.
一個2公尺長,0.2公尺厚的木板比一個2公尺長,0.1公尺厚的木板多160塊
: (2) The cost of a square slab that is 3 meters long and 0.1 meter thick is
: $200 more than the cost of a square slab that is 2 meters long and 0.1 meter
: thick.
一個3公尺長,0.1公尺厚的木板比一個2公尺長,0.1公尺厚的木板多200塊
: 嗯! 其實我是看不太懂題目的意思
: 請大家幫我解答 謝謝^^
答案是C嗎? 要兩個選項才能知道價錢跟長,厚的比率各是多少
應該是這樣吧 希望有回答到你的問題~~~
