Step-by-step explanation:
In a petri dish, a certain type of bacterium doubles in number every 40 minutes.
There were originally 64 or 2 to the 6th power, bacteria in the dish. After 120 minutes, the number of bacteria has doubled 3 times, multiplying by 2 to the 3rd power
Now the population of bacteria is is 2 to the 6th power times 2 to the 3rd power. Expressed as a power, how many bacteria are in the petri dish after 120 minutes?
A. 2 to the 9th power
B. 2 to the 18th power
C.4 to the 9th power
D. 2 to the 3rd power
Answers
Answer: i dont bs , its 2 to the 9th power. i just got %100 on this quiz. 1.3.5 math
Step-by-step explanation:
There are 2 to the 9th power bacteria are in the petri dish after 120 minutes.
Thus, option (A) is correct.
After 120 minutes, the number of bacteria has doubled 3 times, multiplying by 2 to the 3rd power.
Initially, there were 64 bacteria which is equal to [tex]2^6[/tex].
After the first doubling,
= [tex]2^6 * 2^3[/tex]
= [tex]2^9.[/tex]
After the second doubling, the number becomes
= [tex]2^9 * 2^3 \\[/tex]
[tex]= 2^{12[/tex]
After the third doubling, the number becomes
= [tex]2^{12} * 2^3[/tex]
= [tex]2^{15[/tex].
So, after 120 minutes, there are [tex]2^9[/tex] bacteria in the petri dish.
Thus, option (A) is correct.

Hello! :)
2(3x − 5) + 5 = 5x + 13 Simplify both sides of the equation
(2)(3x) + (2)(−5) + 5 = 5x + 13 Distribute
6x + −10 + 5 = 5x + 13
(6x) + (−10 + 5) = 5x + 13 Combine like terms
6x + −5 = 5x + 13
6x − 5 = 5x + 13
6x − 5 − 5x = 5x + 13 − 5x Subtract 5x from both sides
x − 5 = 13
x − 5 + 5 = 13 + 5 Add 5 to both sides
x = 18 (ANSWER)

Which is the solution to this equation 8x -5(x-3) = 18
Answers
Answer:
Step-by-step explanation:
Distribute the -5 to the parenthesis to get:
[tex]8x-5x+15=18\\8x-5x=3\\3x=3\\x=1[/tex]
Answer:
x = 1
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
8x−5(x−3)=18
(Distribute)
8x+−5x+15=18
(Combine Like Terms)
3x+15=18
3x+15=18
Step 2: Subtract 15 from both sides.
3x+15 −15 = 18 −15
3x=3
Step 3: Divide both sides by 3.
3x/3= 3/3
x = 1

Find an equation parallel to y=-5 and passing through (-2, -9)
What is the equation (answer in standard form)
Answers
Answer:
[tex]y=-9[/tex]
Step-by-step explanation:
We want to find an equation of a line that is parallel to y=-5 and also passes through (-2,-9)
Note that y=-5 is a horizontal line.
This means that in order to be parallel to our old line, our new line must also be horizontal.
So, the equation of our new line will be whatever y-coordinate is being used from our point.
Our point is (-2,-9).
The y-coordinate is -9.
So, the equation of our horizontal line is:
[tex]y=-9[/tex]
This is in standard form.
And we're done!

Answers
Answer:
∠BAC = 122°
Step-by-step explanation:
From your notes, you know that ...
∠APB = 90°
12y° = 90°
y = 90/12 = 7.5
Then angle ACP is ...
∠ACP = (4y -1)° = (4(7.5) -1)° = 29°
Angle BAC is the ape.x angle of isosceles triangle BAC, whose base angles are 29°. Hence, ...
∠BAC = 180° -2(29°)
∠BAC = 122°

Answers
Answer:
Neither
Step-by-step explanation:
-12x + 3y = 3
y = 4x + 1
y = mx + b
The second equation given is set up in the correct form already (y = 4x + 1)
We have to convert the first equation into the same format
-12x + 3y = 3
Isolate the y
3y = 3 + 12x
Divide the 3 from the y and the other side
y = 1 + 4x
y = 4x + 1
This is the same as the first equation
They can only be parallel if their slope (m or 4 in this case) is the same and their y-intercepts (b or 1 in this case) are different. Since the equations are the exact same and do not fit the y-intercept criteria for parallel, they cannot be parallel. If they were perpendicular, their lines must cross. This means they have to contain reciprocals or opposite slopes. Our slope here for both of them is 4 or 4/1. Since neither are the opposite (which would be 1/4), it is not perpendicular. Therefore, the answer is neither

Which College entrance exam has the least amount of math problems to work?

Step-by-step explanation:
The two main college entrance exams are the SAT and ACT which are used for almost all colleges in the United States. Between these two the SAT has a lesser focus on math in general. Instead, the SAT tends to focus more on word problems and the process taken to solve them. This does not mean that it has no math at all, there is still a math section on the SAT's but it is not as extensive as in the ACT's.
