Step-by-step explanation:
(5.6) × 1/8
Here the unit fraction is 1/8
multiply 5.6 times 1
so its 5.6. then divide the decimal by 8
we know that 8 times 7 is 56
so 56 divide by 8 is 7
we have decimal point 1 number to the left
so we move decimal point 2 place left
Hence 5.6 divide by 8 is 0.7
Answer: 0.7
Answer:
The population is of 500 after 10.22 hours.
Step-by-step explanation:
The rate of change of the population of a certain organism is proportional to the population at time t, in hours.
This means that the population can be modeled by the following differential equation:
In which r is the growth rate.
Solving by separation of variables, then integrating both sides, we have that:
Applying the exponential to both sides:
In which K is the initial population.
At time t = 0 hours, the population is 300.
This means that K = 300. So
At time t = 24 hours, the population is 1000.
This means that P(24) = 1000. We use this to find the growth rate. So
So
At what time t is the population 500?
This is t for which P(t) = 500. So
The population is of 500 after 10.22 hours.
Answer:
<h2>C.</h2>Step-by-step explanation:
Look at the pictures.
x - sausage
y - bacon
A. 20 pounds of sausage and 90 pound of bacon
x = 20 → y = 100 > 90
B. 40 pound of sausage and 40 pound of bacon
x = 40 → y = 75 > 40
C. 60 pound of sausage and 80 pound of bacon
x = 60 → y = 50 < 80
D. 80 pound of sausage and 20 pound of bacon
x = 80 → y = 25 > 20
