Answer:
2.195%
Step-by-step explanation:
Assuming that both planets are a sphere, we have to:
26590 * 28% = 7445.2
7445.2 miles would be the diameter of the moon, now to calculate the volume, we know that the radius is half the diameter, so:
r2 = d2 / 2 = 7445.2 / 2 = 3722.6
and the radius of the planet would be:
r1 = d1 / 2 = 26590/2 = 13295
now the volume of the planet we know is equal to:
v1 = 4/3 * pi * r1 ^ 3
and the volume of the moon would be:
v2 = 4/3 * pi * r2 ^ 3
We want to calculate the percentage by volume, therefore:
v2 / v1 = 4/3 * pi * r2 ^ 3 / 4/3 * pi * r1 ^ 3
v2 / v1 = 3722.6 ^ 3/13295 ^ 3
v2 / v1 = 0.021952
that is, the volume of the moon represents 2.195%
Answer:
51
Step-by-step explanation:
<h2>12+18=30</h2><h2>30+21=51</h2>
Answer:
175 minutes which would be 10500 seconds
Step-by-step explanation:
first you would multiply 25 by 7 and convert the minutes into seconds
Start by distributing the 4:
12-8x=15
Add 8x to both sides of the equation and subtract 15 from both sides:
8x=-3
divide both sides by 8 to get the value of x:
x=-3/8
The function that has a range limited to only negative numbers is Square Root.
<h3>Can one has the range of a function to be negative?</h3>
The function of this kind is known to be a kind of radical function that is said to have even index e.g. a square root. and thus, this radicand is one that can have a negative value for some or for the values of x.
Note therefore, that The function that has a range limited to only negative numbers is Square Root and thus it is correct.
