BRAInly whats the difference between isolation and separation?
For the las ttime yeahhh, yeahhh,
Im sitting here reminiscing now why we kis.sing b.aby, I gave you top of the line, I know you miss it baby.
I got alot on my mind why don't you listen ba.by?
If you can turn back the time you would've listened ba.by.
You would've listened to the words I swear, yo s.h/i/t would be out in the curve I s.w.ear, I s/w.ear to God you had some nerve I s/we.ar, but that's for listening to them birds out there,I put up with your bu/l/ls.hi.t for the last time, who would of thought that we were f/u/c/ki.ng for the last time (it was the last timmmeee) it was the last time, who would of thought that we were fu/c/k/ing was the last time
I got this s/,h,it yeah I got problems with com/mi/ment ba.b/y,
I apo/logized to you I should have listened ba.by, I wasn't in lo.ve

Answer:
(x - 2)² + (y - 6)² = 4
Step-by-step explanation:
Equation of a circle is given by,
(x - h)² + (y - k)² = r²
Here, (h, k) is the center of the circle
r = Radius of the circle,
From the graph attached,
Center of the circle → (2, 6)
Radius of the circle = 2 units
Therefore, equation of the circle will be,
(x - 2)² + (y - 6)² = 2²
(x - 2)² + (y - 6)² = 4
The three inside angles (A,B and C) of a right-angled triangle are in the ratio 7:18:11. Th smallest angle is 35. Work out angles A, B and C
Answer:
<A = 35degrees
<B =90degrees
<C = 55degrees
Step-by-step explanation:
Given the ratios of a triangle as 7:18:11
Total ratio = 7+18+11
Total ratio = 36
Since the smallest angle is 35degrees, hence <A = 35degrees
Get angle B;
<B = 18/36 * 180 (sum of angle in a triangle is 180degrees)
<B = 1/2 * 180
<B = 90degrees
Get angle C;
<C = 11/36 * 180
<C = 11 * 5
<C = 55degrees
Hence the value of A, B and C are 35, 90 and 55 degrees repectively

Statement 1 and statement 3 contradict
======================================================
Explanation:
We'll start with statement 1 and try to build to statement 3, and you'll find that a contradiction happens.
If angle 1 and angle 2 are supplementary, then that must mean [tex]m \angle 1 + m \angle 2 = 180[/tex] because the angles can be combined to form a straight angle.
Add the measure of angle 3 to both sides
[tex]m \angle 1 + m \angle 2 = 180\\\\m \angle 1 + m \angle 2+m\angle 3 = 180+m\angle 3[/tex]
The left side matches with the left side in statement 3, but the right side is a bit off. That [tex]m\angle 3[/tex] term needs to be zero, so that the right side boils down to simply 180. However, statement 3 specifically mentions that angle 3 is nonzero. So angle 3 is some positive value.
That's why choice C is the answer.
------------------
Here's an example:
Let's say angles 1 and 2 are 50 and 130 degrees. The order doesn't really matter, but I'll make angle 1 to be the smaller angle.
This means,
[tex]m \angle 1 + m \angle 2 = 180\\\\50 + 130 = 180\\\\[/tex]
So we've made statement 1 to be true. The angles 50 and 130 are indeed supplementary.
Now let's add some nonzero value to both sides. This will represent the measure of angle 3. If we add say 10 degrees to both sides, then,
[tex]50 + 130 = 180\\\\50 + 130+10 = 180+10\\\\50 + 130+10 = 190\\\\m\angle 1 + m\angle 2 + m\angle 3 = 190\\\\[/tex]
we don't get 180 like we want in the equation of statement 3. This is where the contradiction happens, more or less. One right side is 180, the other right side is 190. The 190 will change if you use some other value for angle 3, but hopefully you can see that it's impossible to add up angles 1 through 3 to get 180. It's only possible if angle 3 were zero degrees.
We can think of it like angles 1 and 2 hog up all the oxygen, and use up 180 points of it, leaving no air for angle 3 to breathe so that's why angle 3 must be 0. Furthermore, it means that a triangle is not possible if exactly two angles are supplementary.
----------------------
Extra info:
Statements 1 and 2 can coexist just fine without any contradictions happening. If angle 1 is 110 degrees, then that makes angle 2 to be 70 degrees (110+70 = 180). That rules out choice A.Statements 2 and 3 are just fine as well, for similar reasoning as above. We can plug in 110 for angle 1, then subtract that from 180 to get 180-110 = 70. Then from here, just ensure that angles 2 and 3 add to 70. So there are infinitely many ways to do this. Choice B can be ruled out.Choice D is ruled out because we found choice C to be the answer, ie the contradicting two statements.Answer:
C) l and lll

Find the probability of randomly selecting a blue, then a red marble from a bag of 5 red, 8 green, and 3 blue marbles when (a) you replace the first marble before drawing the second, and (b) you do not replace the first marble. Then, compare the probabilities. Round all answers to four decimal places, if necessary. a. The probability of selecting a blue, then a red marble when you replace the first marble before drawing the second is about . b. The probability of selecting a blue, then a red marble when you do not replace the first marble is . You are about times more likely to pick a blue, then a red when you do not replace the first marble.
Answer:
Below.
Step-by-step explanation:
Total marbles = 16
(a) Replacing the first marble:
Probability = 5/16 * 3/16
= 15/256
Not replacing the first marble:
Probability = 5/16 * 3/15
= 5/16 * 1/5
= 5/80
= 1/16.
Comparing the 2 values:
Probability of Not replacement / Replacement = 1/16 / 15/256
= 256 / 15* 16
= 16/15
Thus you are 16/15 = 1.0667 times more likely to pick a blue then a red when you do not replace the first marble.

What is the equation, in standard form, of a circle with center (−5, −9) and radius 7?
Enter your answer by filling in the boxes.
x__^2+y__^2=___
Answer:
Solution given:
Centre(h,k)=(-5,-9)
radius (r)=7
we have
Equation of a circle is;
(x-h)²+(y-k)²=r²
Substituting value;
(x+5)²+(y+9)²=7²
(x+5)²+(y-9)²=49 is a required equation of a circle.
Standard equation
(x-h)²+(y-k)²=r²(x+5)²+(y+9)²=7²(x+5)²+(y+9)²=49Based on the dotplot of the simulation results and the
random sample from last month's new driver's licenses,
which conclusion can be drawn?
The actual proportion of teenagers who do not smile
is only 8%.
It is clear that exactly 6 out of 10 teenagers will smile
in their driver's license photo.
If we continued to take more samples of 10
teenagers, the center of the distribution would shift to
6.
There is about an 8% chance that 4 or fewer
teenagers smiled for their photo. This is not unusual
and is not convincing evidence that the true probability
is less than 60%.

What is the value of n in the equation 3n + 2(n + 2) = 9n + 12? (4 points)
a. −4
b. −2
c. 2
d. 4
Can someone please give me a step by step I am really struggling <3
Answer: n = -2
Step-by-step explanation:
3n +2(n + 2) = 9n + 12
(simplify 2(n + 2)) =
3n + 2n + 4 = 9n + 12
(subtract 9n from both sides)
3n + 2n - 9n + 4 = 12
-4n + 4 = 12
(subtract 4 from both sides)
-4n = 8
(divide -4 from both sides)
n = -2
In a box containing 20 cans, 12 of the cans contain vegetables. In the box, 5 of the cans are dented, with 2 of the dented cans containing
vegetables
What is the probability that a randomly selected can in the box is dented or contains vegetables?
OA 65%
OB. 75%
OC. 95%
OD 85%
Answer: B.) 75%
Step-by-step explanation:
12 cans contain veggies and 5 cans are dented, since two of the dented cans contain veggies don't count those two. This means you'll add 12 and 3 which equals 15. 15 out of 20 is an example of three fourths or 75%.
Jolinda and her parents are discussing how to pay for her college education. The cost of tuition at the college Jolinda wants to attend is $7250 a year. Jolinda's parents can pay 70% of the tuition and Jolinda will have to pay the rest. She has one year to save enough money for the first year of college. What is the minimum amount of money she should save every month to reach this goal?
Answer:
$181.25
Step-by-step explanation:
Given data
Amount= $7250
The amount the parent will pay
=70/100*7250
=0.7*7250
= $5075
Hence the balance left for her to pay is
=7250 -5075
=$2175
Hence the least monthly amount is
=2175/12
=$181.25

Answer:
The answer is B
Step-by-step explanation:
Since we already know that angle A and D are congruent, if angles C and F were also congruent, we can prove the triangles are similar through AA, meaning the triangles have 2 sets of corresponding congruent angles. The other option D doesn’t work because if we were going off on using the sides as a way to prove similarly, than all 3 sides of one triangle would need to be proportional and corresponding to the other 3 of the other triangle (which is not given, so that info isn’t enough, option D only gives us 2 sides of each triangle)
