increase?
12. A culture of bacteria in the lab doubles every 6 minutes. Assume the growth follows a continuous exponential
model and you start with only 2 bacterium.
Using an appropriate exponential base, if this pattern continues to be applicable, find the time in
which the number of bacteria would reach 109. (Round to the nearest minute.)
Answer:
18 minutes
Step-by-step explanation:
if you divide 109 by 6, ya get 18.166666-
You have 200 bottles of Medicine. 99% contain Medicine A; the rest, Medicine B. How many bottles of Medicine A do you need to use/empty to get Medicine A to 98%?
Answer:
I need to empty 2 bottles to get Medicine A to 98% of the total bottles
Step-by-step explanation:
The first step is to find out what 99% of 200 is. This will give us how many bottles of "Medicine A" are present.
99% of 200 is 198. This means that there are 198 bottles of Medicine A present.
The next step is to find out what 98% of 200 is. This will give us the number of bottles of "Medicine A " that will be left remaining.
98% of 200 is 196. There neede to be 196 bottles left after I have taken out and emptied a few bottles of Medicine A.
The last step is to subtract 196 from 198 bottles, to get the number of bottles that I need to empty.
This will be 198 - 196 = 2 bottles
I need to empty 2 bottles to get Medicine A to 98% of the total bottles

PLS SOMEBODY ANSWER IM DESPERATE I NEED AN ANSWER OMGGGG I WILL GIVE BRAINLIEST JUST ANSWERR!!! maria earns $4.76 an hour at the local supermarket. each week, 25% of her total pay is deducted for taxes. in addition, she pays $25 a week, after taxes, in union dues. if she wants her takehome pay to be at least $100 a week, how many hours must she work? show work pls :)
Step-by-step explanation:
Let x be the number of hours Maria work per week.
We have 0.75 * $4.76x - $25 >= $100.
Therefore 0.75 * $4.76x >= $125,
$4.76x >= $166.66
x >= 35.014
Hence Maria have to work at least 36 hours per week.
The point (–5, 6) is located in which quadrant?
A coordinate plane.
Answer:
The point (-5, 6) is located in the second quadrant
Step-by-step explanation:
Answer:
The second quadrant.
Step-by-step explanation:
To plot (-5, 6), we move back 5 units, and up 6, this places us in the second quadrant. Look at the image attached for a labeled coordinate plane.

2y + 3y = 4 - 6 - 13
Answer:
y=-3
Step-by-step explanation:
2y+3y=4−6−13
2y+3y=4+−6+−13
(2y+3y)=(4+−6+−13)
5y=−15
5y=−15
y= −3
Answer:
y = -10
Step-by-step explanation:
You add 2y and 3y, you'd get 5y from it. You do 4-6-13 which is -15.
So 5y = -15.
You subtract 5 from the y side and add 5 to the -15.
So basically:
5y = -15
-5 & +5
y = -10

Step-by-step explanation:
Vertical Angles: Find the Supplementary Angles (photo provided)
Answer:
105°
Step-by-step explanation:
The given angles are vertical and congruent , then
8x - 21 = 6x + 3 ( subtract 6x from both sides )
2x - 21 = 3 ( add 21 to both sides )
2x = 24 ( divide both sides by 2 )
x = 12
Then
6x + 3 = 6(12) + 3 = 72 + 3 = 75°
Supplementary angles sum to 180° , thus
supplementary angle = 180° - 75° = 105°

Complete the square for the following equation x^2-18x
Answer:
Multiple answers would work
Step-by-step explanation:
From the subtraction sign before the 18x, we can infer that one of the equations has a negative number. So, know we have this:
(x-?) (x+?)
There are multiple answers this could be,
(x-18) (x)
(x-20) (x+2)
You get where I am going...
If you went with the first on (x-18) (x), then you wouldn't have to add anything.
(x-20) (x+2) = x^2 - 18X - 40.
To be honest this one stumped me. Some just have multiple answers. My guess is that you have to fill out the boxes so maybe the first answer wouldn't work.
Sorry I couldn't give a concise answer. Though their probably is one obivious answer that I am missing.
Answer:
I think its 16, 32, or 36.

What are the answers to the last two questions?
Answer:
[tex](-1)(x+3)(x-2)[/tex]
Step-by-step explanation:
Factoring
We are given a trinomial:
[tex]-x^2-x+6[/tex]
The following steps are done to factor the trinomial.
1. Confirm there are no common factors: No common factors (given)
2. Factor out -1:
Multiply all the terms by -1 and take -1 out:
[tex]\boxed{(-1)(x^2+x-6)}[/tex]
3. Factor
[tex]x^2+x-6 = (x+p)(x+q)[/tex]
We have to find two numbers p and q whose product is -6 and the sum is 1. Those numbers are 3 and -2 (in any order):
Factoring:
[tex]x^2+x-6 = (x+3)(x-2)[/tex]
The final factoring is:
[tex]\boxed{(-1)(x+3)(x-2)}[/tex]
2. Express each of the following as a rational number in the form of p/q
Where q≠0
Step-by-step explanation:
We need to find each of the following as a rational number in the form of p/q
(a) (3/7)² (b) (7/9)³ (c) (-2/3)⁴
Solution,
(a) (3/7)²
[tex](\dfrac{3}{7})^2=\dfrac{9}{49}[/tex]
(b) (7/9)³
[tex](\dfrac{7}{9})^3=\dfrac{7\times 7\times 7}{9\times 9\times 9}\\\\=\dfrac{343}{729}[/tex]
(c) (-2/3)⁴
[tex](\dfrac{-2}{3})^4=\dfrac{-2\times -2\times -2\times -2}{3\times 3\times 3\times 3}\\\\=\dfrac{16}{81}[/tex]
Hence, this is the required solution.

Step-by-step explanation:
Answer:
11/2
Step-by-step explanation:
Sum of angles in a triangle = 180°
84 + x +59 +x + 31 =180°
84+54+31+x+x = 180°
169 + 2x = 180°
2x = 180 - 169
2x = 11
x = 11/2

Joleen is a sales associate in a clothing store. Each week she earns $250 plus a commission equal to 3% of her sales. This week her goal is to earn at least $460. What is the dollar amount of the sales that she must have to reach to get to her goal? Provide work.
Answer:
She must have to reach $7000 sales to get to her goal.
Step-by-step explanation:
Consider the provided information.
Let her weekly sales is represented by [tex]x[/tex].
Each week she earns $250 plus a commission equal to 3% of her sales. so this can be written as:
[tex]250+\frac{3}{100}x[/tex]
Her goal is to earn at least $460. It means she needs to earn more than or equal to $460.
[tex]250+\frac{3}{100}x\geq 460[/tex]
Now simplify it.
[tex]0.03x\geq 460-250[/tex]
[tex]0.03x\geq 210[/tex]
[tex]x\geq 7000[/tex]
She must have to reach $7000 sales to get to her goal.
Answer:
She must have to reach $7000 sales to get to her goal.

Step-by-step explanation:
Slope of the line using two pairs of values from the table, (-2, 5) and (2, 2):
[tex] slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{2 - 5}{2 - (-2)} = \frac{-3}{4} [/tex]
