Which diagram represents a line of symmetry for the regular pentagon?
Answers
The correct answer is Pentagon 2 or B
Explanation:
In mathematics and related disciplines, a line of symmetry is a line that divides a figure, for example, a triangle, circle, or pentagon into two symmetrical or equal sides. This means you can fold the image following the line and both sides will be identical. This occurs in the second pentagon because the line that begins in the top of the figure divides it into two equal sides. Indeed each of the sides includes half of the base and two angles that coincide if you fold the figure following line.
Answer:
its b
Step-by-step explanation:
literally the only one you can fold in half

Use the fact that d = rt to write the system of equations that represents the scenario. Let x be the speed of Aro's paddling and let y be the speed of the river. Upstream: 5.2 = ( ) Downstream: 5.2 = ( )
Answers
Answer:
Answer: upstream: 5.2= (x-y) 5
Downstream: 5.2= (x+y) 2.5
Step-by-step explanation:
The equations for upstream and downstream motion for time [t] seconds are -
5.2 = (x - y) t
AND
5.2 = (x - y) t
What is the general equation of a Straight line?The general equation of a straight line is -
[y] = [m]x + [c]
where -
[m] is slope of line which tells the unit rate of change of [y] with respect to [x].
[c] is the y - intercept i.e. the point where the graph cuts the [y] axis.
The equation of a straight line in point slope form can be also written as-
[tex]y-y_{1}=m\left(x-x_{1}\right)[/tex]
We have the following problem -
Let x be the speed of Aro's paddling and let y be the speed of the river. Upstream: 5.2 = ( ) Downstream: 5.2 = ( )
We can write the equations for upstream and downstream motion for time [t] seconds as -
Upstream - (Opposing motion)
5.2 = (x - y) t
Downstream - (Supporting motion)
5.2= (x + y) (t/2)
Therefore, the equations for upstream and downstream motion for time [t] seconds are -
5.2 = (x - y) t
AND
5.2 = (x - y) t

Answers
Answer:
Independent: Amount of hours she works
Dependent: Amount of money she makes
Step-by-step explanation:
The independent variable is the part of the equation that changes. In this case the only thing that changes is how long she works, the amount of money she charges and what she is doing does not change.
The dependent variable is what you measure in the equation. In this case, the amount of money she makes depends on the amount of time she works.

A high school graduating class is made up of 351 students. There are 73 more girls than boys. How many boys are in the class?
Answers
Answer:
let x be the number of boys
given, the number of girls are 73 more than the number of boys, meaning number of girls is x + 73
also given is that x + x + 73 = 351
2x + 73 = 351
2x = 351 - 73
2x = 278
x= 139
There are 139 boys
There will be 139 + 73 = 212 girls
139 + 212 = 351 which is the total number of students
let x be the number of boys.
Given, that the number of girls is 73 more than the number of boys, meaning the number of girls is x + 73
also given is that
x + x + 73 = 351
2x + 73 = 351
2x = 351 - 73
2x = 278
x= 139
There are 139 boys
There will be 139 + 73 = 212 girls
139 + 212 = 351 which is the total number of students.

A town's population is 33.950. About 100 people move out of the town cach month. Each month, 125 people on average move into town. A nearby
town has a population of 35,700. It has no one moving in and an average of 150 people moving away every month. In about how many months will the
populations of the towns be equal? Pick the correct equation to model the situation. Then solve the equation and answer the question,
A. 125m-100m+35,700-33,950-150m
B. 125m-100m+33,950-35,700-150m

months
The towns will have equal populations in about
Answers
Question 2 you subtract 35700- 150 =35550 then - 150 from that until both of your problems are equal and that how u find the month it’s 10 months
The equaitons are y = 25m + 33950 and y = 150m + 35700. Then the number of months will be 10 months. Then the correct option is B.
What is a linear equation?A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.
The linear equation is given as,
y = mx + c
Where m is the slope of the line and c is the y-intercept of the line.
Let 'm' be the number of months and 'y' be the population. Then the equations are given as,
y = (125 - 100) m + 33,950
y = 25m + 33950 ...1
y = 150m + 35700 ...2
From equations 1 and 2, then we have
150m + 35700 = (125 - 100) m + 33950
125m - 100m + 33950 - 35700 - 150m = 0
175m = 1750
m = 10 months
The equaitons are y = 25m + 33950 and y = 150m + 35700. Then the number of months will be 10 months. Then the correct option is B.

How do I solve this ?
Answers
Answer:
Base is 5/6
Step-by-step explanation:
We calculate the area of a triangle by multiplying height to the base and that divided by two
Let's call the base X
5/36 cm^2 = 1/3 × X ÷ 2 multiply both sides of the equation by 2
2 × 5/36 = 1/3 × X ÷ 2 × 2
5/18 = X/3 now divide both sides by 3
5/18 ÷ 3 = X/3 ÷ 3
X = 5/6
