It is known that 1 m is equal to 100 cm and that 1 km is also equal to 1000 m. Thus, the conversion may be done by the dimensional analysis and the use of proper conversion factors.
(86000 cm) x (1 m/ 100 cm) x (1 km / 1000 m) = 0.86 km
Therefore, the answer is 0.86 km.

Triss [41]

Answer: The original number of CDs is between 1000 and 1500.

Step-by-step explanation:

Since we have given that

Number of copies of a popular CD left to be sold in the store = 15

According to question, this is between 15 and 1.5% of the original number of copies of the CD in the store.

Let the original number of copies of the CD in the store be 'x'.

Now, 15 is equal to 1% of the original number of copies of the CD, it becomes

$1\%\ of\ x=15\\\\\frac{1}{100}\times x=15\\\\x=15\times 100\\\\x=1500$

Or if 15 is equal to 1.5% of the original number of copies of the CD, it becomes

$1.5\%\ of\ x=15\\\\\frac{1.5}{100}\times x=15\\\\\frac{15}{1000}x=15\\\\x=\frac{15\times 1000}{15}\\\\x=1000$

Hence, the original number of CDs is between 1000 and 1500.

ratelena [41]

Louis is walking at 4 mph. If Louis can walk 2 miles in 30 minutes, she can then walk 4 miles in an hour if you double the amount of time she is walking from 30 to 60, so you would also double the distance. She is walking at 4 miles per hour.
