least common multiple of the given three numbers can be found out as follows
first have to divide all three numbers by factors that are common for all three
so first divide 55, 75 and 115 by 5
55/5 = 11
75/5 = 15
115/5 = 23
there are no common factors shared by 11, 15 and 23
so the factors are 5, 11 , 15 and 23
so to find the least common multiple
we have to find the products of the factors
5 x 11 x 15 x 23 = 18 975
least common multiple is 18 975
Answer:
Formula:
Plug in values: radius = 9.3
Volume: 1072.476π cubic units
Step-by-step explanation:
The formula to find the volume of a sphere is , where r = radius. In this case, we leave the volume of sphere in terms of pi.
- The only value we can plug in is the radius. In this case, the radius is 9.3 units.
Now, we can solve for the volume:
Answer:
6
Step-by-step explanation:
2x+4=16
2x=12
x=6
This is the number of combinations of 2 from 23
23C2 = 23! / 2! 21!
A quick way to do this is 23*22 / 2 = 253
