The population of the city next year, after decreasing, will be 359,778
Here, we are given that the population of a city decreases by 1.7 percent per year.
This, means that the city's population will decrease by 1.7% in 1 year, (1.7 × 1.7)% in 2 years and so on.
The population of the city this year is given to be 366,000.
Thus, next year, the population will decrease by-
1.7% of 366,000
= 1.7/100 × 366,000
= 17/10 × 3,660
= 17 × 366
= 6,222
Thus, the city's total population next year will be-
366,000 - 6,222
= 3,59,778
Hence, the city's population to the nearest individual comes out to be 359,778.

Jerald is having drain issues at his home and decides to call a plumber. The plumber charges $35 to come to his house and $50 for every hour they work. If the plumber charges Jerald a total of $190, how many hours did the plumber work?
Write and solve an equation to determine the number of hours worked by the plumber.
50x + 35 = 190; x = 3.1 hours
50x − 35 = 190; x = 4.5 hours
35x + 50 = 190; x = 4 hours
35x − 50 = 190; x = 6.9 hours
The equation to determine the number of hours worked by the plumber is 190 = 35 + 50x and the number of hours is 3.1 hours option (A) is correct.
What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
It is given that:
Jerald is having drain issues at his home and decides to call a plumber.
The plumber charges $35 to come to his house and $50 for every hour they work.
Let x be the number of hours:
190 = 35 + 50x
50x = 155
x = 3.1 hours
Thus, the equation to determine the number of hours worked by the plumber is 190 = 35 + 50x and the number of hours is 3.1 hours option (A) is correct.

Frank is riding his bicycle for 6 hours at a speed of 9.6 kilometers per hour. For how many kilometers does he ride?
Solve the following inequality:
4c<14-3c
Answer: x < 2
Step-by-step explanation:
To solve this, we will isolate the variable c.
Given:
4c < 14 - 3c
Add 3c to both sides of the equation:
7x < 14
Divide both sides of the equation by 7:
x < 2
Find the value of r so the line that passes through the pair of points has the given slope. ( − 2 , 8 ) , ( r , 4 ) , m = − 1 2
The line that passes through the pair of points has the given slope. ( − 2 , 8 ) , ( r , 4 ) , m = − 1 2, then the intersection with the domain is r = -5/3.
The line that passes through the pair of points has the given slope is,
( − 2 , 8 ) , ( r , 4 ) and m = -12
What is Slope :Slope, numerical measure of a line's inclination relative to the horizontal. In analytic geometry, the slope of any line, ray, or line segment is the ratio of the vertical to the horizontal distance between any two points on it (“slope equals rise over run”).
m = rise/run
[tex]m=\frac{y_{2} -y_{1} }{x_{2}-x_{1} }[/tex]
Where,
m = slope
[tex](x_{1} ,y_{1} )[/tex] = coordinates of first point in the line
[tex](x_{2} ,y_{2} )[/tex] = coordinates of second point in the line
Then, we can find the [tex]m_{1}[/tex]
We can use these two values, ( − 2 , 8 ) , ( r , 4 )
x1 = -2
y1 = 8
x2 = r
y2 = 4
m = [tex]\frac{4-8}{r-(-2)}[/tex]
[tex]m = \frac{-4}{r+2}[/tex]
We can substitute m= -12 value into m= -(4/r+2)
So,
We can write,
-12 = [tex]\frac{-4}{r+2}[/tex]
We can find the domain,
If the fraction is defined, the dominator can not be equal to zero.
2 + r ≠ 0
Rearrange variables to the left side of the inequality,
r ≠ -2
Append the inequality as the domain,
r ≠ -2
We can solve the equation,
-12 = [tex]\frac{-4}{r+2}[/tex]
Multiply both sides of equation by the common denominator,
-12 (r+2) = -4(r+2)/ (r+2)
Reduce the fractions,
-12 (r+2) = -4
Apply the distributive property,
-12r - 24 = -4
Rearrange variable to the left side of the equation,
-12r = -4 + 24
Calculate the sum or difference,
-12r = 20
Divide both sides of the equation by the coefficient of variables,
r = - 20/12
r = -5/3
Therefore,
The intersection with the domain is r = -5/3, so the line that passes through the pair of points has the given slope. ( − 2 , 8 ) , ( r , 4 ) , m = − 12.

The graph shows how much snow fell after a certain amount of time measured in hours. 2. Do you think that there may be a proportional relationship between the number of hours and the amount of snow that fell? Explain your reasoning.
Due to different rates of change in each case, neither graph shows a proportional relationship.
When does a graph represents a proportional relationship?A graph represents a proportional relationship if the output variable y in the y-axis can be written as a product of the input variable x in the x-axis and the constant of proportionality k, as follows:
y = kx.
Item 1Between days 0 and 10, the plant grew by 4 centimeters.Between days 30 and 40, the plant grew by 8 centimeters.For the first case, the rate of change is of:
k = 4/10 = 0.4.
For the second case, the rate of change is of:
k = 8/10 = 0.8.
Different rates, hence cannot be written as proportional relationship.

which lines are parallel if angle 4 = angle 5? justify your answer
r and s are the parallel lines, if ∠4 equals ∠5.
Given,
The figure with,
Four lines: Line r, Line s, Line l and Line m.
Angles: ∠1, ∠2, ∠3, ∠4, ∠5, ∠6, ∠7 and ∠8
Here, we have to find the parallel lines when ∠4 = ∠5
Lets see:
Angle 1 and angle 4 are the same because the opposite angles created by two crossing lines are identical. As a result, angle 1 also equals angle 5.
The corresponding angles are identical when two parallel lines cross across a line. To put it another way, if r and s are parallel, the angles created when l intersects r and s are same. Angle 1 equals Angle 5, Angle 2 equals Angle 6, etc. We can infer that r and s are parallel since we know that angle 1 Equals angle 5.
So, we can conclude that if ∠4 equals ∠5, then r and s are the parallel lines.

2. The sum of two integers is -38,one of them is -22.Find the other.
3. In a competitive exam, Gopi gets 4 marks for each correct answer and -2 for each wrong answer. If he gives 32 correct answers and 8 wrong answers, what will be his total score?
7 × 12 = 72 satisfies the closure property of multiplication, the other integer when the sum is - 38 and one integer is - 22 will be - 16 and the total score for Gopi will be 112 marks.
1)
Closure property of multiplication:
It states that if two real numbers a and b are multiplied, then the product will be a real number as well.
We have 7 × 12 = 72
7, 12 and 72 all are real numbers.
So, it is a closure property under multiplication.
2)
Sum = - 38
a = - 22
We need to find b
a + b = - 38
- 22 + b = - 38
b = - 38 + 22
b = - 16
3)
1 correct answer = 4 marks
1 incorrect answer = - 2 marks
Number of correct answers = 32
Number of incorrect answers = 8
Total score = 32 × 4 + (- 2) × 8
= 128 - 16
= 112 marks.
Therefore, we get that, 7 × 12 = 72 satisfies the closure property of multiplication, the other integer when the sum is - 38 and one integer is - 22 will be - 16 and the total score for Gopi will be 112 marks.

Given that,
In the picture there is a scissor.
The scissor has intersecting lines with angles 1,2,3,4.
∠1=159° and ∠3 is 159°.
We have to find the angles ∠2 and ∠4.
Two straight lines that intersect at the same location are said to be intersecting lines. The junction point is the place where two intersecting lines meet. Four angles are created when two lines cross. The four angles added together always equal 360 degrees. There is a unique connection between the angles created when lines intersect.
The straight line has 180°
∠1+∠2=180°
159°+∠2=180°
∠2=180°-159°
∠2=21°
Now,
∠3+∠4=180°
159°+∠4=180°
∠4=180°-159°
∠4=21°
Therefore, the angle ∠2=21° and ∠4=21°.
