100/6
120/100 x = 20
x = 100/6 = 50/3
Answer:
To find the volume in terms of pi, leave pi in the formula rather than converting it to 3.14. Multiply the radius times the radius. For example, if the radius of your sphere equals 19 inches, multiply 19 by 19 to get 361 square inches.
First: 4/10 aka 2/5
Second: 3/9 aka 1/3
126.5 years
Step-by-step explanation:
N(t) = 384(1.13)^t
2,000,000,000 = 384(1.13)^t
(1.13)^t = 2,000,000,000/384
log [(1.13)^t) = log (2,000,000,000/384)
t × log 1.13 = log (2,000,000,000/384)
t = [log (2,000,000,000/384)]/(log 1.13)
t = 126.5
