There are 2,100 bacteria in a circular petri dish. The dish has a radius of 40 millimeters. What is the approximate population d
1 answer:
Answer:
B) 0.42
Step-by-step explanation:
population density=number of people/square units
we plug in 2,100 for the first one but we don't know the second one for that we need the area which is A=π so the radius is 40 millimeters so
=1600 1600*π=5024
2,100/5024=0.417 round it up and it is 0.42
so B) 0.42 is the answer

Answer by JKismyhusbandbae: expression 2 and expression 1
Look at the four expressions. Simplify any expressions that can be simplified to see which two are equivalent.
8v × 30v = ( 8 × 30) × ( v × v) =
Since expression 2 can be simplified to expression 1, they are equivalent.
It will take 0.4 seconds to get to the home plate.
Given:
The speed of the pitch thrown by Justin is 100 miles per hour
The distance of home plate from the pitching rubber is 60.5 feet
To find:
The time taken by a pitch to reach the home plate
Solution:
The distance home plate from the pitching rubber = d = 60.5 feet
The speed of pitch thrown by Justin = s = 100 miles/hr
The time taken by a pitch to reach the home plate = t =?
The speed of the moving object is given by dividing the distance covered from the time taken to cover that distance.
In an hour there are 3600 seconds, then in 0.000114583 hours will be:
It will take 0.4 seconds to get to the home plate.

Step-by-step explanation:
We can solve the first equation, f of -3. The value of the function f is , and plugging in -3 gets us
, this results in 10 divided by negative 2, which is negative 5.
Now, we must solve g of negative one third. The function g is defined as . Plugging in negative one third into the question gets us
9 times negative one third is -3, and -3 minus 15 is -18. The absolute value of -18 is 18.
Now, we must solve h of negative 2, and h is defined as . Plugging in negative 2, we have
. Negative 8 times negative 2 is positive 16, and 16 minus 3 is 13. The answer is the square root of 13
