The number of bags of mulch that is needed to cover the playground is 3,605 bags.
<h3>How many bags of mulch is needed?</h3>
The first step is to determine the volume of the surface of the city playground. The volume is the product of the length, width and height of the playground.
Volume = length x width x height
4 x 40.5 x 66.75 = 10,813.50 inches³
The second step is to determine the number of bags of mulch that is needed to cover the surface of the playground.
Number of bags of mulch = volume of the playground / volume one bag can cover
10,813.50 inches³ / 3 = 3,604.5 bags ≈ 3,605 bags

Answer:
275 minutes 12 seconds
Step-by-step explanation:
Given that :
slowest running time per mile = 9 minutes and 14 seconds
fastest running time per mile = 7
minutes and 58 seconds.
To estimate the time taken to run 16 miles ;
Obtain the Average of the two run times :
(9 minute 14 seconds) + (7 minutes 58 seconds) = 17 minutes 12 second
Hence it takes an average of 17 minutes 12 seconds per mile
Time taken to run 16 miles :
((17 * 60) + 12) * 16 = 16512 seconds
16512 / 60 = 275 minutes 12 seconds

Answer:
The migration of the African-Americans to Harlem in the USA empowered the African-Americans in the society in the early 1900s. This was one of the greatest accomplishments of the African-Americans in history.
Explanation:
The "Harlem Renaissance" was originally called the "New Negro Movement." During the "Reconstruction Era," many of the African Americans felt a newfound empowerment in the society. They started leaving the South, where most of them were enslaved and maltreated. Many of them moved to other places such as "Harlem" in New York City. It became an ideal destination for many "Negros" and their number increased over time.<u> This then became an African-American neighborhood</u>.
African-Americans started producing plays with actors of their descent. Several Negro poets emerged describing the life of the African-Americans. Negros became more literate and able when it comes to expressing themselves in the society. They even had their own newspaper known as<em> "The New Negro Movement."</em>
