The main three units of temperature are- Celsius(C), Fahrenheit(F) and Kelvin(K). We can convert one from the other by using specific formulas. The formula to convert Fahrenheit to Celsius is {eq}F= \dfrac{9}{5}C+32 {/eq}.The formula to convert Kelvin to Celsius is {eq}K=C+...
“Where” 是对地点进行提问的疑问词,例如 “Where is your book?”(你的书在哪里?),温度不是关于地点的概念,所以 B 选项也不符合。分析选项 C:“What” 可以用来对事物的性质、内容等进行提问,在这里 “What is the temperature?”(温度是多少?),回答 “40 degrees” 是合理的。因此,正确答案是 C。
If an angle is 60 degrees and another angle is 30 degrees, what is the sum of these two angles? A. 80 degrees B. 90 degrees C. 100 degrees D. 120 degrees 相关知识点: 试题来源: 解析 B。解析:60 度加 30 度等于 90 度,这道题考查角度加法的基本运算,需要注意计算准确。
