The angles ∠4 and ∠6 are found to be supplement angles.
What are termed as the supplement angles?Supplementary angles are the ones that total 180 degrees. Angles 130° and 50°, for example, are supplementary angles since the sum of 130° and 50° equals 180°. Complementary angles, on the other hand, add up to 90 degrees. When the 2 supplementary angles are joined together, they create both a straight line and an angle.It should be noted, however, that the two supplementary angles are not required to be adjacent to each other. As a result, any two angles could be supplementary if their total amount is equal to 180°.For the given question;
∠5 ≅ ∠6 ( both are congruent means equal)
As, ∠4 and ∠5 are forming on the straight line. Thus,
∠4 + ∠5 = 180 (linear pair)
But, ∠5 ≅ ∠6 , replacing ∠5 with ∠6 .
∠4 + ∠6 = 180 supplement angles.
Thus, ∠4 and ∠6 are found to be supplement angles.

8. Stavros has 22 coins in his piggy bank, all dimes and quarters. Altogether, the
coins are worth more than $3.40. At least how many coins are quarters? At most,
how many of the coins are dimes?
Answers
Stavros has 9 at least quarters and 13 at most coins.
Define inequality.In mathematics, inequalities specify the connection between two non-equal numbers. Equal does not imply inequality. Typically, we use the "not equal sign (≠)" to indicate that two values are not equal. But several inequalities are utilized to compare the numbers, whether it is less than or higher than.
Given Data
Stavros has 22 coins in his piggy bank, all dimes and quarters. Altogether, the coins are worth more than $3.40.
He only has quarters and dimes in his possession. For quarters and dimes, assign variables.
Let x = the quantity of dime
Let y = the quantity of quarters.
Create an inequality and equation to depict the scenario.
We can use an equation because he has exactly 22 coins.
x + y = 22
He has more than $3.40 in his total, thus we can apply an inequality.
0.10x + 0.25y > 3.40
To figure out how many of each coin he possesses, we apply the substitution approach. In order to express the inequality in terms of x, substitute the equation into the inequality.
0.10x + 0.25(22 - x) > 3.40
The inequality can now be resolved.
0.10x + 5.5 - 0.25x > 3.40
-0.15x + 5.5 > 3.40
-0.15x > -2.1
x > 14
In an equation where we divide by a negative coefficient, We reverse the sign in inequality.
x < 14
Stavros has a maximum of 13 dimes.
The value of x can then be substituted into the equation since an equation provides you the most precise and minimal value you can have.
y = 22 - 13
y = 9
Stavros has 9 quarters and 13 dimes.

Answer:
30.2 meters
Step-by-step explanation:
The key is to realize that a 30 60 90 triangle can be constructed and the height of the house can be found from there. It may be helpful to draw a diagram.
I will use the diagram attached for reference to this solution.
Remember that the answer is asking for y, or the length of DE.
The angle CAB is 30 degrees, and the angle ACB is 90 degrees
The length of CB is 25 * sqrt3
Since ACB is a 30 60 90 triangle, and we know the length of one of the sides, the length of the other sides can be calculated.
CB is the shortest length, and so the middle length, AC, is sqrt(3) times longer than the length of the shortest length, CB
CB's length * sqrt 3 = AC's length = 25 * sqrt3 * sqrt3
AC = 75
length of A to F (I can't combine the letters a and f because then brainly thinks i'm swearing ) = 75 + x = 107
x = 32
Since length of BE = length of CF,
32 = BD + DE = 1.8 + y
y = 30.2 meters

And why there two possible solutions to the equation, X over 2 = 100?
Answers
There are two possible solutions because a power is involved. This can be shown in the graph. When we graph to the power of 2, we get a parabola. This gives us two x-intercepts, giving us two answers.
And why is this? When you square a negative number, you get a positive number since a negative times a negative is a positive.
Example: 2 * 2 equals 4, and -2 * -2 also equals 4. This means both 2² and (-2)² are equal to 4.
This means that we will get a positive and negative number value that both equal the same thing when being squared, which is why you get two possible solutions to this equation.

Answer:

Step-by-step explanation:
To do this, you know that Jake had a goal of getting $150 in the week. He was within $25 of reaching his goals. This means that he could have $25 less than or more than $150.
You can subtract 25 from 150 to get his minimum:

The translation is the process of moving the shape to left/right of up or down. During the translation process the shape and size of the graph will not change. In translation we are only changing the coordinates of the points of the shape.
Here it is translated 6 units up.
During the upward motion it will be positive
g(x) = f(x) + 6

What is exponential growth of population?Exponential growth occurs when a population's per capita growth rate remains constant regardless of population size, causing the population to grow faster and faster as it grows larger.
In exponential growth, the per capita (per individual) growth rate of a population remains constant regardless of population size, causing the population to grow faster and faster as it grows larger. In nature, populations may grow exponentially for a time, but they are eventually constrained by resource availability.
Given that,
P represents population, and
t the number of years of growth.
As we know,
P = [tex]a(b)^{t}[/tex]
[here 'a' is the initial amount of population and 'b' is the amount of growth or shrink]
To get 'b,' start at 1 and either add or remove the decimal growth rate depending on whether it is rising or decreasing.
In this case a = 17,000, it is the value of population at the time zero.
As the population decreases 4% each year, then b = 1-0.04 = 0.96

The cost of the entrance tickets to the zoo for 2 adults and 3 children is $78.80. the cost of the entrance tickets for 1 adult and 1 child is $33.10 . what is the cost of the entrance ticket for a child
Answers
The cost of the entrance ticket for a child is $12.80.
Using algebraic expression and equation, we can express each statement and determine the cost of the entrance ticket for a child
Let x = cost of the entrance ticket for a child
y = cost of the entrance ticket for an adult
If the cost of the entrance tickets to the zoo for 2 adults and 3 children is $78.80, then we can express this as:
3x + 2y = $78.80 (equation 1)
If the cost of the entrance tickets for 1 adult and 1 child is $33.10, then we can express this as:
x + y = $33.10 ⇒ x = $33.10 - y (equation 2)
Substitute equation 2 to equation 1 and solve for y.
3x + 2y = $78.80 (equation 1)
3($33.10 - y) + 2y = $78.80
$99.30 - 3y + 2y = $78.80
3y - 2y = $99.10 - $78.80
y = $20.30
Substitute the value of y to equation 2 and solve for x.
x = $33.10 - y (equation 2)
x = $33.10 - $20.30
x = $12.80
cost of the entrance ticket for a child = $12.80

What are inequality expressions?Inequality expressions are mathematical statements that are represented by variables, coefficients and operators where the opposite sides are not equal
How to solve the inequality expression?The inequality expression is given as
2(7-4k) > 12 or 5 < 0.2(15k + 10)
Open the brackets
So, we have
14 - 8k > 12 or 5 < 7.5k + 2

So, we have
- 8k > 12 - 14 or 5 - 2 < 7.5k
Evaluate the like terms
So, we have
- 8k > -2 or -3 < 7.5k
Divide both sides by the coefficient of k
So, we have
k < 0.25 or -0.4 < k

The equation that is parallel to y = -3x + 7 and passes through the point (2, -1) is y=-3x+5.
What is slope Intercept form?The slope intercept form in math is one of the forms used to calculate the equation of a straight line, given the slope of the line and intercept it forms with the y-axis.
y=mx+b
where m is the slope of the line and b is the y intercept.
The slope of the given equation,
y=-3x+7 is -3.
So, to write an equation parallel to the given equation and set of points, use point slope form and the slope of -3
y-y₁=m(x-x₁)
where (2,-1) are x₁, y₁
y-(-1)=-3(x-2)
y+1=-3(x-2)
Multiply with 3 on RHS side
y+1=-3x+6
We have to write in slope intercept form, so shift 1 to RHS.
y=-3x+6-1
y=-3x+5
As you can see, the slope of this line is -3
