Answer:
<em>It will take 26.34 minutes for the population to reach 5 times its initial value</em>
Step-by-step explanation:
<u>Exponential Growing</u>
The population of bacteria grows at a rate expressed by the equation:
Where t is in minutes.
We need to know when the population will reach 5 times its initial value. The initial value can be determined by setting t=0:
Now we find the time when the population is 5*256=1,280. The equation to solve is:
Dividing by 256:
Taking natural logarithms:
Applying the logarithm properties:
Solving for t:
It will take 26.34 minutes for the population to reach 5 times its initial value
Answer: 1.1
1.01 x 1.1 = 1.111
I hope this is good enough:
This problem asks for the surface area of the box, since the contact paper covers the outside (like wrapping paper). The box is 11 x 8 x 9, its length, width, and heighth respectively. And the formula for the surface area of the box is
SA = 2(lw + wh + hl)
SA = 2(11*8 + 8*9 + 9*11)
SA = 2(88 + 72 + 99)
SA = 2(259)
SA = 508 square inches
We are told the contact paper costs eight cents a square inch.
508 square inches x 8 cents / square inch
= $41.44 (the square inches divide out)
Thus, Erin spent $41.444 on contact paper.
So 1 and 1/3 times 5/6
first convert 1 1/3 into improper fraction (x/y)
1 1/3=3/3+1/3=4/3
4/3 times 5/6=(4 times 5)/(3 times 6)=20/18=10/9
the answer is 10/9 or 1 and 1/9 or 1 1/9
