\frac{18000}{x} = 150 \quad \Rightarrow \quad x = 120 \] 4. 由此可得玉兰树单价为: \[ 1.5x = 1.5 \times 120 = 180 \] 5. **验证**: - 银杏树数量:\( 12000 \div 120 = 100 \)棵 玉兰树数量:\( 9000 \div 180 = 50 \)棵 总数量:\( 100 + 50 = 150 \)棵,与题目...
【解析】写出积是12000的不同算式 $$ 1 2 \times 1 0 0 0 = 1 2 0 0 0 $$ $$ 1 2 0 \times 1 0 0 = 1 2 0 0 0 $$ $$ 1 2 0 0 \times 1 0 = 1 2 0 0 0 $$ $$ 1 2 0 0 0 \times 1 = 1 2 0 0 0 . $$ 故答案为:12,1000;120,100;1200,10;12000,1.【乘...
The bend radius of an optical fiber must be at least 10 times larger than its diameter. Install or remove optical fibers carefully to avoid damages to fiber connectors. If a fiber connector is dirty, use an alcohol swab or a piece of air-laid paper to gently wipe the fiber connector in...
\[ 12000 \text{公里} = 12000 \times 1000 \text{米} = 12,000,000 \text{米} \]接下来，我们可以考虑一些实际的例子来帮助理解这个距离。例如，地球赤道的周长约为40075公里，因此12000公里大约是地球赤道周长的三分之一：\[ \frac{12000 \text{公里}}{40075 \text{公里}} \approx 0.3...
