What is a graph?In Mathematics, a graph can be defined as a type of chart that is typically used for the graphical representation of data points on both the horizontal and vertical lines of a cartesian coordinate, which are the x-coordinate (x-axis) and y-coordinate (y-axis).
Additionally, the graph of any proportional relationship is always modeled by a straight line with the data points passing through the origin (0, 0).
In this scenario, we can reasonably and logically deduce that all of the data points in this graph are represented by the red symbols.

The residents of a city voted on whether to raise property taxes. The ratio of yes votes to no votes was 5 to 4. If there were 6183 total votes, how many yes votes were there?
The number of yes votes on whether to raise property taxes, using proportions, was of 3345, considering that 6183 total votes.
What is a proportion?A proportion is a fraction of a total amount, and equations are built with these fractions and the rates in the context of a problem to find the desired measures in the problem using basic arithmetic operations such as multiplication and division.
One application of proportions is for ratio problems, as one ratio between two amounts a and b is given by the division of a by b, and over the total, these rates are:
Fraction of a: a/(a + b).Fraction of b: b/(a + b).The ratio of yes votes to no votes was 5 to 4, hence the fraction of yes votes is given as follows:
5/(5 + 4) = 5/9.
The total number of votes was of 6183, hence the number of yes votes is calculated as follows:
5/9 x 6183 = 3435 total yes votes.

What is triangle?
A triangle is a polygon with three edges and three vertices. The sum of all the angles of a triangle is 180 degrees. Mathematically -
∠x + ∠y + ∠z = 180°
The sum of two sides of a triangle is greater then the third side. Mathematically -
a + b > c
There are different types of triangles such as -
equilateral triangle , scalene triangle , isosceles triangle etc.
Given are the sides of triangle as AB = 18cm, BC = 18cm, AC = 16cm.
The given triangle is a isosceles triangle with two sides equivalent. Angles opposite to these sides will be equal. So, we can write -
2∠x + ∠y = 180°
from the figure, it can be seen that angle B is 5.38 degrees.
2∠x + 5.38 = 180
2∠x = 174.62
∠x = 87.31°
Therefore, the angle measurements are 5.38°, 87.31° and 87.31°.

Lance Whittingham IV specializes in buying deep discount bonds. These represent bonds that are trading at well below par value. He has his eye on a bond issued by the Leisure Time Corporation. The $1,000 par value bond pays 4 percent annual interest and has 18 years remaining to maturity. The current yield to maturity on similar bonds is 12 percent. Use Appendix B and Appendix D for an approximate answer but calculate your final answer using the formula and financial calculator methods.
a. What is the current price of the bonds?
b. By what percent will the price of the bonds increase between now and maturity? (Round "PV Factor" to 3 decimal places, intermediate and final answers to 2 decimal places. Omit the "%" sign in your response.) Price increases by %
a) The current bond price (present value) is $420.03.
b) The percentage by which the price of bonds will increase between now (current) and maturity (18 years) is 138%.
How is the bond price determined?The current bond price represents its present value.
The present value is the discounted future cash inflows.
We can compute the present value using an online finance calculator as follows:
N (# of periods) = 18 years
I/Y (Interest per year) = 12$
PMT (Periodic Payment) = $40 ($1,000 x 4%)
FV (Future Value) = $1,000
Results:
PV = $420.03
Sum of all periodic payments = $720.00
Total Interest = $1,299.97
Percentage increase in bond price = [(Future value - Present value)/Present value x 100]
= 138% [($1,000 - $420.03)/$420.03 x 100]
Thus, the present value of the bonds $420.03 will grow by 138% at maturity.

In the proportional relationship table, x would represent distance and y, weight.
The complete table is given in the explanation below.
What is a Proportional Relationship?If two variables that have quantities that vary proportionately are x and y, then the constant of proportionality that lies between both varies can be calculated as k = y/x. The equation for the proportional relationship would be expressed as y = kx.
x represents distance (cm)
y represents weight (newtons).
Using the pair of value that is given in the table, (20, 28), the constant of proportionality, k, would be:
k = y/x = 28/20
k = 1.4
The equation would be y = 1.4x.
Use the equation to complete the table by substituting the value of each missing variables:
Row 2, when x = 55:
y = 1.4(55)
y = 77
Row 3, when y = 140:
140 = 1.4x
140/1.4 = x
100 = x
x = 100
Row 4, when x = 1:
y = 1.4(1)
y = 1.4
The table would be:
Distance (cm) Weight (newtons)
Row 1 20 28
Row 2 55 77
Row 3 100 140
Row 4 1 1.4

Alan has 229 songs on a playlist. He's categorized them in the following manner: 11 rock, 21 Latin American, 46 gospel, 30 country, 39 rap, 25 classical, and 57 pop. If Alan begins listening to his playlist on shuffle, what is the probability that the first song played is a rock song?
=================================================
Work Shown:
11 rock songs
229 total
11/229 is the probability of randomly selecting a rock song. The fraction doesn't reduce since 11 and 229 have no factors in common (other than 1).
If you wanted to convert to decimal form, then 11/229 = 0.04803 approximately. This converts to about 4.803%

-8b+ 2 + 6b = -3b + 7
Answer:
b = 5
Step-by-step explanation:
Add 8b to both sides :
2+6b = 5b+7
Subtract 5b from both sides :
2+b = 7
Subtract 2 from both sides :
b = 5
Let's check :
-8(5) + 2 +6(5) = -3(5) + 7
-40 + 2 + 30 = -15 + 7
-38 + 30 = -8
-8 = -8
Correct
Hope this helped and have a good day
Answer:
b = 5
Step-by-step explanation:
to solve this you must first combine like terms
-8b + 2 + 6b = -3b + 7
combine (add) -8b and 6b
that makes -2b
-2b + 2 = -3b + 7
now add 3b to both sides to put b on one side
-2b + 2 + 3b = -3b + 3b + 7
b + 2 = 7
now subtract 2 to both side
b + 2 - 2 = 7 - 2
b = 5

Susie is visiting the U.S. from Mexico. One day she stopped by a market and found a stall selling tomatoes for 0.83 dollars per pound. If 1 peso was worth 0.053 dollars that day, how much did the tomatoes cost in pesos per kilogram?
First fill in the two blanks on the left side of the equation using two of the ratios. Then write your answer rounded to the nearest hundredth on the right side of the equation.
The value of given ratio is 34.45 peso/kg as the given ratio are : 1 peso/0.053 dollar, 0.053 dollar/1 peso, 1 kg/2.2 lbs, 2.2 lbs/1 kg, 0.83 dollar/1lbs.
What is ratio?An ordered pair of numbers a and b, written as a / b, is a ratio if b is not equal to 0. A proportion is an equation that sets two ratios at the same value. For instance, you could write the ratio as follows: 1: 3 if there is 1 boy and 3 girls (for every one boy there are 3 girls). The ratio can be defined as the number that can be used to represent one quantity as a percentage of another. Only when the two numbers in a ratio have the same unit can they be compared. Ratios are used to compare two things.
Given ratio,
1 peso/0.053 dollar
0.053 dollar/1 peso
1 kg/2.2 lbs
2.2 lbs/1 kg
0.83 dollar/1lbs * 2.2 lbs/1 kg* 1 peso/ 0.053 dollar = 34.45 peso/kg
The value of the given ratio is 34.45 pesos per kilogram because the ratios are 1 peso/0.053 dollar, 0.053 dollar/1 peso, 1 kg/2.2 lbs, 2.2 lbs/1 kg, 0.83 dollar/1lbs.

Juan must add a volume of 7 cubic feet for the enlarged sandbox.
How much sand must we add to an enlarged sandbox?
The volume occupied by the sandbox (V), in cubic feet, is represented by the volume formula for a parallelpiped:
V = w · l · h
Where:
w - Width, in feetl - Length, in feeth - Height, in feetJuan wants to know the additional amount of sand required for the enlarged sandbox. If we know that the initial volume is equal to a cubic foot and each length is double, then we find that the resulting volume for sandbox is:
V' = (2 · w) · (2 · l) · (2 · h)
V' = 8 · (w · l · h)
V' = 8 · V
V = 8 ft³
The addition of sand is found by the following subtraction:
