Answer: 55 degrees
Step-by-step explanation:
a+90+35=180 ==> a straight line measures 180 degrees and the angles a, a right angle, and 35 lie on that line. A 180 degree angle is called a straight angle. Also, if there is a tiny box in between an angle, that means that the angle is a right angle.
a+125=180
a+125-125=180-125
a=180-125
a=55 degrees

The equation that represents the linear relationship between the x- values and y-values in the table is y = 6x - 5 .
What is a linear equation?
An algebraic equation of the form y=mx+b is referred to as a linear equation. m is the slope, and b is the y-intercept, and all that is involved is a constant and a first-order (linear) term. The variables in the preceding equation are y and x, and it is occasionally referred to as a "linear equation of two variables."
The equation y = 6x - 5 can represent the linear relationship between the x- values and y-values because it satisfies all the given values for x and y.

Solve each equation. Check each solution. 11/3x - 1/3 = -4/x²
The solutions of the given equation 11/3x - 1/3 = -4/x² are x = -1 and x = 12
In this question, we have been given an equation.
11/3x - 1/3 = -4/x²
We need to solve given equation.
⇒ 11/3x - 1/3 = -4/x²
⇒ (33 - 3x)/9x = -4/x²
⇒(33 - 3x)/9 = -4/x
⇒ x(33 - 3x) = -36
⇒ -3x² + 33x + 36 = 0
⇒ x² - 11x - 12 = 0
⇒ x² - 12x + x - 12 = 0
⇒ x(x - 12) + 1(x - 12) = 0
⇒ (x - 12)(x + 1) = 0
⇒ x - 12 = 0 or x + 1 = 0
⇒ x = 12 or x = -1
Now we need to check above solutions.
Substitute x = 12 in given equation.
⇒ 11/3(12) - 1/3 = -4/(12)²
⇒ 1/3 (11/12 - 1) = 1/3(-4/48)
⇒ -1/12 = -1/12
⇒ LHS = RHS
Now substitute x = -1 in given equation.
⇒ 11/3(-1) - 1/3 = -4/(-1)²
⇒ -12/3 = -4/1
⇒ -4 = -4
⇒ LHS = RHS
Therefore, the solutions of the given equation 11/3x - 1/3 = -4/x² are x = -1 and x = 12

The length of the roller coaster track from the top of a hill to the bottom of the hill is 125 feet at a 53°C angle with the vertical. If the position at the top of the hill is (x, y) , use function notation to describe the translation to the bottom of the hill. Round to the nearest foot.
(x + 100, y - 75) is the function notation used to characterise the translation to a bottom of the hill.
What is defined as Pythagorean Theorem?The Pythagorean theorem states that the sum of a squares on a legs of a right triangle equals the square on hypotenuse (this same side opposite this same right angle)—or, in recognizable algebraic notation, a² + b² = c².
Now, as per the given question;
From the shown diagram,
AC = b
Ab = c
We must find the coordinates of a point B. If C(x,y), then the coordinates of points A and B are:
A(x, y−b) and B(x+c, y−b)
We need to figure out b and c. To find c, we should use sine function.
sinC = perpendicular/hypotenuses
sinC = c/BC
Thus, c = BC sinC
c = 125sin53°
=125⋅0.79863551
c ≈100
To find b, we are using the Pythagorean Theorem.
BC² = AC² + AB²
125² = b² + 100²
b² = 125² - 100²
b = √5625
b = 75
The coordinates of a point B are as follows:
B(x+c, y−b)
B(x+100, y−75).
Therefore, the translation to the bottom of the hill defined by the function notation is B(x+100, y−75).

Answer:
Step-by-step explanation:
1. We know it travels 346 meters in a second, we now need to multiply 346 by 20. This equals 6920
2. Sound travels 5971 meters per second. We need to multiply this by 12 to find the distance it travels in 12 seconds. 71652 meters
3. We know sound travels 5971 meters per second in stone and 5000 meters per second from the chart. We need to find the difference between these and multiply that by 17 to find the distance covered in 17 seconds.
5971-5000=971
971*17=16507
Sound travels 16507 more meters in 17 seconds through stone than it would travel in aluminum
Write an equation of the line through each pair of points. Use point-slope form.(-1/2, -1/2) and (-3,-4)
The equation of the line in point-slope form, which passes through the pair of points located at (-1/2 , -1/2) and (-3 , -4), is y + 1/2 = 7/5(x + 1/2).
The equation of a line can be expressed in three different forms: standard form, slope-intercept form, and point-slope form.
The standard form of an equation of a line is expressed as ax + by = c, where a and b, if all possible must be integers, are the coefficients of variable x and y, respectively, and c is a constant. Meanwhile, slope-intercept form is given by the formula y = mx + b, where m is the slope of the line and b is the y- intercept. On the other hand, given the slope m and a point on the line (x , y), we can express the equation in point-slope form, (y - y1) = m(x - x1).
Getting the slope of the two points: (-1/2 , -1/2) and (-3 , -4).
m = (y2 - y1)/(x2 - x1)
m = (-4 - -1/2)/(-3 - -1/2)
m = (-7/2)/(-5/2)
m = 7/5
Using the point slope form, plug in the values of the slope and one point to set up the equation.
(y - y1) = m(x - x1)
where m = 7/5 and (x1 , y1) = (-1/2 , -1/2)
(y - -1/2) = 7/5(x - -1/2)
y + 1/2 = 7/5(x + 1/2)

Find the sum of each finite arithmetic series. 8+9+10+. . . . . . +15
The sum of finite arithmetic series 8+9+10+. . . . . . +15 is 92
Suppose we are given an arithmetic series:
a(1) + a(2) + ... + a(n)
Then the sum is:
S(n) = n/2 (a(1) + a(n))
Where: a(1) = first term
a(n) = nth term
The given series is:
8+9+10+. . . . . . +15
We need to find n such that a(n) = 15.
Recall that in an arithmetic sequence:
a(n) = a(1) + (n -1) . d
where d = difference between 2 consecutive terms.
Substituting a(1) = 8, and d = 9 - 8 =1 into the formula:
a(n) = 8 + (n -1) . 1
15 = 7 + n
n = 8
Substitute n = 8 into the sum formula:

Question 1
A pair of running shoes is on sale for $125.99. If the sale price is discounted 9% from the original price, what is the
original price?
Answer:
$138.45
Step-by-step explanation:
The original price was 100% of the original price since 100% is the whole thing.
The price was discounted by 9%.
100% - 9% = 91%
That means the discounted price is 91% of the original price.
Let x = original price.
91% of x = $125.99
0.91x = 125.99
x = 125.99/0.91
x = 138.45
Answer: $138.45
What is the solution of the system of equations? x+3y = 5 , -2x - 4y = -5.
The solution of the system of equations involving x + 3y = 5 and -2x - 4y = -5 is (-5/2 , 5/2).
A system of linear equations is a set of two or more equations which includes common variables. To solve system of equations, we must find the value of the unknown variables used in the equations that must satisfy both equations.
There are three methods that can be used to solve system of linear equations.
1. Elimination
2. Substitution
3. Graphing
Using substitution method, given two linear equations in x and y,
x + 3y = 5 (equation 1)
-2x - 4y = -5 (equation 2)
Using the first equation, find the value of one variable, lets say x, in terms of the other.
x + 3y = 5 (equation 1)
x = 5 - 3y
Substitute the equation of x to the second equation.
-2x - 4y = -5 (equation 2)
-2(5 - 3y) - 4y = -5
-10 + 6y - 4y = -5
Combining all terms containing the variable y on one side and the constants on the other side of the equality, and solving for y.
-10 + 6y - 4y = -5
6y - 4y = -5 + 10
2y = 5
y = 5/2
Substitute the value of y in the equation of x.
x = 5 - 3y
x = 5 - 3(5/2)
x = 5 - 15/2
x = -5/2
Hence, the solution of the given system of equations is (-5/2 , 5/2).

If Edgar is a high school senior who has great grades and just received a notification that he was awarded a few scholarships in the amounts of $4,500, $7,500, and $750 while his expected tuition with books and fees is $25,000, then the amount of money Edgar will need to pay for the rest of his education bill is equal to $12,250.
The amount of money Edgar will need to pay can be determined by the subtraction of the total tuition with books and fees from the total amount of scholarships awarded to Edgar.
The total amount of scholarships awarded to Edgar can be determined by the sum of all of the scholarships.
Total amount of scholarships = 4500 + 7500 + 750
Total amount of scholarships = $12,750
Now the amount that Edgar will need to pay for the rest of his education bill can be determined by subtraction.
Amount to be paid by Edgar = Tuition with books and fees - Total amount of scholarships
Amount to be paid by Edgar = 25,000 - 12750
Amount to be paid by Edgar = $12,250
Hence, the amount of money Edgar will need to pay for the rest of his education bill is calculated to be $12,250.
