Answer: 0.9
Step-by-step explanation:
V=(1/3)hpir^2
v=130
h=13
r=x
130=(1/3)(13)pix^2
times both sides by 3
390=13pix^2
divide both sides by 13
30=pix^2
divide both sides by pi
30/pi=x^2
sqrt both sides
x≈3.09
radius is abou 3 units
Step-by-step explanation:
7.50= (1 + x/100 ) × 5.50
7.50/ 5.50 = 1+x/100
x/100 = 0.36
x= 36.36%
Answer:
1130040
Step-by-step explanation:
so what your going to do is it sounds like 3 turns = 3 hours so 1 turn= 1 year so theres 8760 hours in a year so thats going to be 8760 turns now multiply thar by 129 and you get your awnser.
Number 1 is 0.2 and 0.4
number 2 is 0.53 and 0.56
number 3 is on the 0.3
number 4 is 1/3
number 5 is a little bit before the 0.7 mark
