Type the correct answer in the box. Round your answer to the nearest hour. A scientist running an experiment starts with 100 bacteria cells. These bacteria double their population every 15 hours. Find how long it takes for the bacteria cells to increase to 300. Use the formula , where is the original number of bacteria cells, is the number after t hours, and d is the time taken to double the number. It takes 15 hours for the number of bacteria to increase to 300.
Answer:
so 15 hour for the 100 to become 200 and then it will become 400 in another 15 hours. but we need to find the time for 300 so it will take half of 15 hours
+ 15 hours for it to become 300 cells which is: 7 1/2 + 15 = 22 hours and 30 minutes

Find the 50th term of the following
arithmetic sequence 5, 9, 13, 17?
Answer:
201
Step-by-step explanation:
First you need to know the position to term rule and to find this you use a formula which is:
tn = an + b
Where tn is the term number, a is the difference between the other terms.
So the tposition to term rule here is 4n+1.
Then we substitute n for the value 50 making it 4(50) + 1 = 201.
201 is the 50th term
Write an absolute value equation with-1 and 5 as the solution.
Answer:
it is detailed solution. please mark brainlest.
Thank you have a nice day
The equation of the absolute function that has the solutions of -1 and 5 will be |x - 2| = 3.
What is an absolute function?The absolute function is also known as the mode function. The value of the absolute function is always positive.
The absolute function is given as
f(x) = | x |
The solutions of the absolute function are -1 and 5. Then the equation of the absolute function will be
x = -1, 5
Subtract -2 from both sides, then we have
x - 2 = -3, 3
Then apply Mode on both sides, then the equation will be
|x - 2| = 3
The equation of the absolute function that has the solutions of -1 and 5 will be |x - 2| = 3.

How do you convert 3.2 (2 repeating) as a fraction?
Answer:
3+2/9 = 29/9
Step-by-step explanation:
examples:
4/9 = 0.444444
8/9 = 0.888888
3/9 = 0.3333333
7/9 = 0.777777
1/9 = 0.111111111
2/9 = 0.22222222
80/99 = 0.808080
67/99 = 0.6767676767
44/99 = 0.4444444
12/99 = 0.1212121212
345/999 = 0.345345345
i think you get the point.
so we know 2/9 = 0.22222, so now just add a 3:
3+ 2/9 = 27/9 + 2/9 = 29/9

Plane P is a cross-section of the solid below. What shape is the cross section?
A. not enough information
B. rectangle
C. hexagon
D. pentagon
A rectangle exists as a quadrilateral with four right angles Option B. rectangles the cross section.
What is rectangle?
In Euclidean plane geometry, a rectangle exists as a quadrilateral with four right angles. It can also be described as an equiangular quadrilateral since equiangular compromises that all of its angles exist equal, or a parallelogram including a right angle. A rectangle with four sides of equivalent length exists as a square.
In mathematics, solid geometry or stereometry exists the traditional name for the geometry of three-dimensional, Euclidean spaces. Stereometry accords with the dimensions of volumes of different solid figures, including pyramids, prisms, and other polyhedrons; cylinders; cones; truncated cones; and balls bordered by spheres.
Hence,Option B. rectangles the cross section.

Solve the equation.
-(x + 2) – 2x = -2(x + 1)
x = [?]
Answer:
x = 0
Step-by-step explanation:
-(x + 2) – 2x = -2(x + 1)
-x-2-2x = -2x-2
-3x-2 = -2x-2
-3x+2x = -2+2
x = 0
Answer:
x = 0Step-by-step explanation:
-(x + 2) – 2x = -2(x + 1)
=> - x - 2 - 2x = -2x - 2
=> - 2 + 2 = - 2x + 2x + x
=> 0 = x or x = 0 (Ans)

i need to know whether it is the minimum or maximum function and what that number is as well as where x axis intercepts the quadratic graph . i need to know if there are any roots in the quadratic graph, and i need to know when y=1 , the value of x could be x= or x=
Answer:
The minimum value of this quadratic function is -4.
At the point (-4, 0), the x-axis intercepts with the quadratic graph.
There is 1 root of this quadratic equation.
Approximately, when y=1, the x value could be -5 or -3.
