Step-by-step explanation:
Rate of growth equals 420/100 = 4.2 times per hour
So after t=three hours,
size of culture = 100*(4.2)^t = 100*4.2^3=7408.8 bacteria,
round to nearest unit 7409 bacteria after three hours (after initial size of 100).
Answer:
$2220
Step-by-step explanation:
Step one
Given data
Principal= $2000
rate= 1.1%= 0.011
time= 10 years
<u>Required</u>
<u>The final amount A</u>
Step two;
For simple interest, the final amount is given as
A=P(1+rt)
substitute
A=2000(1+0.011*10)
A=2000(1+0.11)
A=2000(1.11)
A=2220
$2220
Suppose the number is y >>>>>So y/2 +2y/3 <14
multiply both sides by 6>>>>>>>>>. 6y/2 +6x2y/3 <14x6
3y + 4y < 84
7y <84
y <84/7
y < 12
Answer:

Answer:
13.9
Step-by-step explanation:
Use Pythagorean Theorem:
Both of the lengths given are the legs,
13.5^2 + 3.2^2 = c^2
182.25 + 10.24 = c^2
192.49 = c^2
13.87 = c
