Answers
Answer:
1 and 2 is adjacent. 1 and 3 are vertical. 3 and 4 are adjacent. 2 and 4 are vertical angles.
Angles ∠1 and ∠2 as well as angles ∠3 and ∠4 are linear and supplementary angles. And angles ∠2 and ∠4 as well as ∠1 and ∠3 are vertically opposite angles.
What is an angle?Angle is the space between the line or the surface that meets. And the angle is measured in degree. For complete 1 rotation, the angle is 360 degrees.
Supplementary angle - Two angles are said to be supplementary angles if their sum is 180 degrees.
Vertically opposite angle - When two lines intersect, then their opposite angles are equal.
Linear angle - If the total of two angles is 180 degrees, they are said to be linear angles.
Angles ∠1 and ∠2 are linear and supplementary angles.
Angles ∠1 and ∠3 are vertically opposite angles.
Angles ∠3 and ∠4 are linear and supplementary angles.
Angles ∠2 and ∠4 are vertically opposite angles.

So, [tex] \widehat{AB} \:\&\: \widehat {BA}[/tex] are semicircular arcs.
[tex] \therefore m\widehat {AB} =m\widehat {BA} = 180\degree [/tex]
[tex] \because \: m\widehat {BC} = m\widehat {BA} - m\widehat {CA} [/tex]
[tex] \therefore \: m\widehat {BC} = (180-92)\degree [/tex]

-25-2x=3x
I know the answer to the problem but i´m not sure how to move the constant (-25) to the other side. When you move the constant to the right side the equation should be -2x=3x+25. How do you move a constant to the other side?
Answers
In this case I believe you would add 25 to both sides. The -25 +25 would cancel out and then +25 would be on the right.

Scientists measure a bacteria population and find that it has 10,000 organisms. Five days later, they find that the population has doubled. Which function f could describe the bacteria population d days after scientists first measured it, assuming it grows exponentially?
Answers
Answer:
f(x)= 10,000(2)^x
Step-by-step explanation:
Exponential equations can be modeled by a(r)^x where a is the initial amount, r is the difference, and x is how many units the equation should be squared by.
A function that describes the bacteria population after d days would be,[tex]\bold{f(d) = 10000\times(1+0.15)^d}[/tex]
What is an exponential growth?An exponential growth function is a function that grows at a constant percent growth rate.
What is an exponential growth function?f(t) = a×(1 + r)^(t)
where f(t) = exponential growth function
a = initial amount
r = growth rate
t = number of time intervals
For given example,
initially a bacteria population (a) = 10,000
Five days later, they find that the population has doubled.
d = 5, f(5) = 20,000
Assuming it grows exponentially, we find the growth rate of a bacteria population by using the formula of exponential growth function.
[tex]\Rightarrow f(d) = a\times(1 + r)^{d}\\\\\Rightarrow f(5) = 10000\times (1+r)^5\\\\\Rightarrow 20000=10000\times (1+r)^5\\\\\Rightarrow 2=(1+5)^5\\\\\Rightarrow 1+r=\sqrt[5]{2}\\\\\Rightarrow 1+r = 1.15\\\\\Rightarrow r = 1.15-1\\\\\Rightarrow \bold{r = 0.15}\\\\\Rightarrow \bold{r=15\%}[/tex]
This means, the exponential growth function would be,
[tex]\bold{f(d) = 10000\times(1+0.15)^d}[/tex], where d represents number of days.

Answer:
11 73/78 ≈ 11.9359 (not 14)
Step-by-step explanation:
The similarity statement tells us ...
QS/QR = FG/FH
QS = QR·FG/FH
13x -14 = 154(55/60) = 847/6
Adding 14 = 84/6, we have ...
13x = 931/6
x = 931/78 = 11 73/78 . . . . . . . divide by 13
__
Comment on the question
You get a nice integer answer for x if the similarity statement is written ...
∆FGH ~ ∆QRS . . . . . . . note the letters are in alphabetical order
Then you have ...
QS/QR = FH/FG
13x -14 = 154(60/55) = 168
13x = 182
x = 14
This nice answer to a nice similarity statement leads us to believe the question has an error in it.
We suspect you are expected to provide x=14 as the answer, even though that is NOT the answer to the question as written. You may want to discuss this with your teacher.

How many ounces of a 28% alcohol solution and a 40% alcohol solution must be combined to obtain 51 ounces of a 32% solution?
Answers
Answer:
Number of ounces of 28% alcohol = x = 34 ounces
Number of ounces of 40% alcohol = y = 17 ounces
Step-by-step explanation:
Let us represent the
Number of ounces of 28% alcohol = x
Number of ounces of 40% alcohol = y
Our system of equations =
x + y = 51 ..... Equation 1
x = 51 - y
28% × x + 40% × y = 32% × 51
0.28x + 0.4y = 16.32......Equation 2
We substitute 51 - y for x
0.28(51 - y) + 0.4y = 16.32
14.28 - 0.28y + 0.4y = 16.32
- 0.28y + 0.4y = 16.32 - 14.28
0.12y = 2.04
y = 2.04/0.12
y = 17
Solving for x
x = 51 - y
x = 51 - 17
x = 34
Therefore,
Number of ounces of 28% alcohol = x = 34 ounces
Number of ounces of 40% alcohol = y = 17 ounces

Answer: 63
Step-by-step explanation:
All triangles' angles added up should be 180 degrees, so 70+47=117 and 180-117=63.
180 = a+b+c
180 = 47 + 70 + c
180 - 47 - 70 = c
