In a biology lab, 500 bacteria reproduce by splitting. Every hour, on the hour, each bacterium splits into two bacteria.
Answer:hour 1 500, hour 2 1000, hour 3 2000 , hour 4 4000
Step-by-step explanation:
After 1 hour 500 bacteria split into 500 bacteria.
After 2 hour 500 bacteria split into 1000 bacteria.
After 3 hour 500 bacteria split into 1500 bacteria.
After 4 hour 500 bacteria split into 2000 bacteria.
Given that,
In a biology lab, 500 bacteria reproduce by splitting.
Every hour, on the hour, each bacterium splits into two bacteria.
We have to find,
Find the number of bacteria after 4 hours.
According to the question,
Let us assume n = the number of bacteria at a given hour.
Total number of bacteria = 500
At the end of 1 hour each of the 500 bacteria after an hour is split in to 2 bacteria. So, at the end of 1 hour = n(1) = 1 × 500 = 500 After 1 hour 500 bacteria split into 500 bacteria.At the end of the 2 hour, each of the 500 bacteria will split in to 2 more bacteria. So, n(2) = 2 x 500 = 1000 bacteria After 2 hour 500 bacteria split into 1000 bacteria.At the end of the 3 hour, each of the 500 bacteria will split in to 2 more bacteria. So, n(3) = 500 x 3 = 1500 bacteria After 3 hour 500 bacteria split into 1500 bacteria.At the end of 4 hours, each of the 500 bacteria spilt into 2 more bacteria.
So, n(4) = 4 × 500 = 2000 bacteria
After 4 hour 500 bacteria split into 2000 bacteria.

Riley is saving up to buy a new television. She needs a total of $1,150.89. Riley has saved $200.13 already and earns $79.23 per
week at her job. How many weeks does Riley need to work to save enough money to buy the new television?
A. 12
B. 13
C. 11
D. 10
Answer:
A. 12
Step-by-step explanation:
$1,150.89 - $200.13 = $950.76
$950.76 / $79.23 weekly = 12 weeks
To check:
12 weeks x $79.23 = $950.76
$950.76 + $200.13 = $1,150.89
please help! What is the product in the form ax^2+bx+c
Answer:
a=2, b=2, c=-12
Step-by-step explanation:
Since it's in factor form, you would first distribute using foil to get [tex]2x^{2} -4x+6x-12[/tex] and then combine like terms when necessary. In this case, the fully simplified version is [tex]2x^{2} +2x-12[/tex]. Therefore your a is 2, b is 2, and c is -12.

Answer:
angle ABC is 130 degrees
Step-by-step explanation:
This is the quickest and simplest way to gind the answer.
Angle CBD and angle ABC are linear pairs. Linear pairs are supplementary meaning angle CBD and angle ABC equal 180 degrees. Since angle CBD is 50 degrees and you know both angles need to add up to 180 degrees all you need to do is subtract 180 from 50 degrees.

Answer:
x=1.46875 or x=1.5
Step-by-step explanation:
1st step subtract 1.8 on both sides
-9.6x=-14.1
2nd step divide -9.6 on both sides
x=1.46875
or
x=1.5

How does a quadratic function relate to volleyball and what aspects of quadratic functions are there?
Answer:
Volleyball players want to keep their serves as close to the net as possible, so the ball travels for a shorter period of time. Say a volleyball player serves the ball across the court. If we can model this situation with the function y=-0.006(x−21)2+9, where x is the distance from the player and y is the height, then we can determine if the ball clears the net and lands in bounds 61 feet away1. It may be helpful to analyze this situation graphically, and we consider how to do that in this section.

Which expression shows the prime factorization of 180?
22 X 32 X 5
2 X 32 X 52
2 X 3 X 5
22 X 3 X 52
Answer:
1- 3520
2- 3328
3- 30
4- 3432
Step-by-step explanation:
========================================================
Explanation:
To find the prime factorization, we'll start by dividing 180 by the smallest prime number
Divide 180 by 2 to get 180/2 = 90
Divide that by 2 to get 90/2 = 45
Then note how 45/2 = 22.5 isn't a whole number, so that means we move onto the next prime number 3
45/3 = 15
15/3 = 5
The denominators we used, in order, were: 2, 2, 3, 3
This means that 2*2*3*3 is part of the factorization. We can condense that to 2^2*3^2
The last term 5 is the final missing piece of the factor puzzle
Meaning, 2^2*3^2*5 = 180
I recommend you use a calculator to confirm this.

Ast year at rt university the ratio of the number of students accepted to the number of students applying for admission was 2 to 7 rt niversity accepted 630 students last year how many students applied to the rt university last year
Answer: 2205
Step-by-step explanation:
Ratio of the number of students accepted to the number of students applying for admission = 2:7
Number of students accepted = 630 students
Number of students that applied will then be represented by x. This will be:
2/7 = 630/x
2 × x = 630 × 7
2x = 4410
x = 4410/2
x = 2205
The number of students that applied to the university was 2205

Jabal and Michael are walking to school and agree to leave their homes at the same time.
Jabal leaves his house walking 2.5 meters per second, Michael leaves his house walking 6 meters per second
Jabal's house is 15 meters closer to school than Michael's house, therefore he is starting 16 meters closer than Michael
After how long are the boys walking together? Use any strategy you'd like to solve
Answer:
We can write the position equation as:
P(t) = speed*time + initial position.
If we define Jabal home as the 0 of the position, then Jabal's initial position is 0m
And we know that his speed is 2.5 m/s, then his position equation is:
Pj(t) = (2.5 m/s)*t
We know that Michael speed is 6m/s, and we also know that his house is 15m further away from school than Jabal's one, then Michael's initial position is -15m
Michael's position equation is:
Pm(t) = (6m/s)*t -15 m
The boys will be walking together when they meet, and this will happen when their positions are the same, this means that:
Pj(t) = Pm(t)
That is the equation we need to solve for t.
(2.5 m/s)*t = (6m/s)*t -15 m
15m = (6m/s)*t - (2.5 m/s)*t = (3.5 m/s)*t
15m/(3.5 m/s) = t = 4.28 seconds.
The boys will walk together after 4.28 seconds.
This is an expression 3.2.t Evaluate the expression when t = 1

Based on this data, what is a reasonable estimate of the probability that Nate scores 8-11 points next basketball game?
Answer:
[tex]Probability = \frac{8}{25}[/tex]
Step-by-step explanation:
Given
See attachment for graph
Required
Determine the probability of getting a score of 8 - 11 points in the next game
From the attachment, the frequency of the class 8 - 11 is:
[tex]Class\ 8 - 11 = 8[/tex]
Also, from the attachment, the total frequency is:
[tex]Total = 3 + 5 + 8 + 6+2+1[/tex]
[tex]Total = 25[/tex]
The required probability is:
[tex]Probability = \frac{n(8 - 11)}{Total}[/tex]
[tex]Probability = \frac{8}{25}[/tex]
