2. If you used the 23 cm basketball as your Moon sphere, how big

1 answer:

6 0

Ok so I heard this question a few times already and couldn't remember how it went so I decided to put my brain to the test, I used my algebra to use and complete it.

If the Earth were shrunk down to the size of a basketball (radius:4.69 inches) the Moon would be a tennis ball (radius: 1.2768 inches, to be exact) 23.5 feet away.

The Sun would be a 42.6-foot sphere (source) located 1.7 miles away.

The closest star, Proxima Centauri, would still be 463,151 miles away – almost twice the distance of the actual moon."

Identify the percent of change as an increase or decrease 38 staples to 55 staples find the percent of change round to the neare

erik [133]

Answer:

The percent of change is 44.7%

Step-by-step explanation:

Given that:

38 staples to 55 staples

As the number of staples are increased, therefore, the percent will also increase.

Difference = 55 - 38 = 17 staples

Percent of change = $\frac{Difference}{Original\ number}*100$

Percent of change = $\frac{17}{38}*100$

Percent of change = 0.447*100

Percent of change = 44.7%

Hence,

The percent of change is 44.7%
