Answer:the need to buy 3600 pencils.

Step-by-step explanation:

In 2005 the city agency spent $2000 to buy pencils at a cost of $5 a dozen. This means that the number of dozens of pencil that they bought in 2005 is

2000/5 = 400

There are 12 pencils in a dozen. Therefore, total number of pencils that they bought in 2005 is

400 × 12 = 4800 pencils

if the agency used 3/4 of these pencils in 2005, it means that the number of pencils that they used in 2005 is

3/4 × 4800 = 3600

The number of pencils left is

4800 - 3600 = 1200 pencils

If they use the same number of pencils in 2006, then the number of pencils that they have to buy is

4800 - 1200 = 3600 pencils

Michael timed a train using a clock. the train traveled a distance of half mile from t = 10 seconds to t = 55 seconds. what was
Alekssandra [29.7K]

Answer:

<em>58.7 ft/sec</em>

Step-by-step explanation:

The train traveled half a mile.

1 mile = 5280 ft

0.5 mile = 0.5 * 5280 ft = 2640 ft

A time from 10 sec to 55 sec is 55 sec - 10 sec = 45 seconds.

2640 ft in 45 seconds

speed = distance/time

speed = 2640 ft / 45 sec = 58.6666... ft/sec

Answer: speed = 58.7 ft/sec
