Answer:
115 bacteria
Step-by-step explanation:
The function that gives the number of bacteria in a science experiment is:
f(x) = 30(1.4)^x
Where x is the number of days
After 4 days (x = 4), the number of bacteria will be:
f(4) = 30 * (1.4)^4
f(4) = 39 * 3.8416
f(4) = 115.248 = 115 (To the nearest whole number)
The number of bacteria after 4 days is 115.
We have to deal with the distance in more detail
If the turtle is 11 times faster than the snail, the amount of distance he will cover is 11 times more.
d/(360 - d) = 1/11
11d = 360 - d
12d = 360
d = 30 The Snail covers 30 meters. The turtle covers 11*30 = 330 meters.
Answers
Rate of snail = 30 meters / 40 minutes = 3/4 meter / minute
Rate of turtle = 330 meters / 40 minutes = 8.25 meters / minute.

Answer: 1/2
Step-by-step explanation:
The numbers that are less than 6 are 1, 2, 3, 4, and 5. Thus simply means that there are 5 numbers that are less than 6.
The probability that she chooses a number less than 6 will then be:
= 5/10
= 1/2
