Answer:
The volume of new sphere is 3.375 times greater than the volume of old sphere
Step-by-step explanation:
Let r be the radius of old sphere. This old sphere is dilated by a scale factor of 1.5 to create a new sphere, so the radius of new sphere is R=1.5r.
The volume of the sphere can be calculated using formula

Hence,

5x if x= 2/5 . 5/1x 2/5= 10/5= 2
5/x = 5/5= 1
8/3_ 1 = 8/3- 3/3= 5/3
1/2+ 3/4 = 2/4+3/4= =5/4
Answer:
Rational: 0.51 and 0.52
Irrational: sqrt(.26) and sqrt(.27)
Answer:
60th caller.
the 12th caller would hit a number divisible by 20 at 60.
12,24,35,48,60
7x-x=19-7
6x=12
x=2
