Let's look at the formula for the volume of a sphere:
Volume = (4/3) (pi) (radius)³ .
If you multiply the radius of a sphere by 'anything',
then the volume gets multiplied by (anything)³ .
Going the other direction, if you multiply the volume by
'something', then the radius gets multiplied by ∛(something).
In this question, the ratio of the volumes is 3 .
So the ratio of the radii (radiuses) is ∛3 = about 1.442 (rounded)
Answer:
1) 7 Miles
2) $750
3) I did not get what it was asking, sorry.
Step-by-step explanation:
1) It is 5 dollars per mile.
You can divide 35 by 5 to get to 7 miles.
2) You find the constant by dividing one of the pairs, in this example, I chose the first row of numbers.
Divide $100 by 4, which will get you $25 per session.
Multiply 30 by 25 which will get you $750
If 39 is 3/5 of all the people then you can divide it by 3 (=13) and multiply is by 5 (= 65)
