Answer:
165
Step-by-step explanation:
Here we have to use the ratio.
Both earth and Pluto are in similar shapes.
To find the number of sphere the size of Pluto does it take to have the same volume, we need to divide the earth's volume by Pluto's volume.
= Earth's volume/Pluto's volume
= 4/3 π (6371)^3 ÷ 4/3 π (1161)^3
Cancelling out 4/3 π both in the numerator and in the denominator, we get
= (6371)^3 ÷ (1161)^3
= 258596602811 ÷ 1564936281
= 165.24
Approximately 165 spheres the size of Pluto to cover the earth volume.
Thank you.
When an exponent is raised to another exponent, you can multiply the powers to simplify them.
3/8*3/4
<em>*Multiply numerators*</em>
3*3=9
<em>*Multiply denominators*</em>
8*4=32
x^9/32
Hope this helps!!
The kind of probability is being used when one calculates the probability that a randomly selected adult who works from home and has a bachelor's degree or higher is <em>relative frequency.</em> This probability is based on actual measurements, like a survey. Using this method will enable us to calculate for the probability of each variable occurring, or a combination of two or more variables with respect to the number of trials in the sample.
