The number of points Jim scored is 15 points.
The number of cars given the ratio of car to boat is 140 cars
How to solve algebraic expression?Number of points Kevin has = xNumber of points Jim has = 8 + xTotal points = 22Total points = Number of points Kevin has + Number of points Jim has
22 = x + (8 + x)
22 = x + 8 + x
22 = 2x + 8
22 - 8 = 2x
14 = 2x
divide both sides 2
x = 14/2
x = 7
Number of points Jim has = 8 + x
= 8 + 7
= 15 points
Part B:
Boat : car
2 : 5 = 56 : x
2/5 = 56/x
cross product
2 × x = 56 × 5
2x = 280
divide both sides by 2
x = 280/2
x = 140
Therefore, the number of points Jim scored is 15 points and the number of cars is 140

. The points (–5, 26) and (3, 26) are located on the same parabola. What is the equation for the axis of symmetry for this parabola?
The equation for given two points of parabola will be (x+1)^2=y-10.
What is parabola?
A parabola is a U-shaped plane curve where any point is at an equal distance from a fixed point (known as the focus) and from a fixed straight line which is known as the directrix.
In general, if the directrix is parallel to the y-axis in the standard equation of a parabola is given as:
y^2 = 4ax
If the parabola is sideways i.e., the directrix is parallel to x-axis, the standard equation of a parabola becomes,
x^2 = 4ay
Apart from these two, the equation of a parabola can also be y2 = -4ax and x2 = -4ay if the parabola is in the negative quadrants.
Now,

The drama club is selling tickets to their play to raise money for the show's expenses. Each student ticket sells for $6.50 and each adult ticket sells for $11. The auditorium can hold a maximum of 130 people. The drama club must make a minimum of $1100 from ticket sales to cover the show's costs. Also, they can sell at least 90 adult tickets. If x x represents the number of student tickets sold and y y represents the number of adult tickets sold, write and solve a system of inequalities graphically and determine one possible solution.
The graph for the inequality is attached below.
What is Inequality?Mathematical expressions with inequalities are those in which the two sides are not equal. Contrary to equations, we compare two values in inequality. Less than (or less than or equal to), greater than (or greater than or equal to), or not equal to signs are used in place of the equal sign.
Given:
Each student ticket sells for $6.50 and each adult ticket sells for $11.
let the number of student ticket sold be x and number of adult ticket sold be y.
so, the inequality is
x + y < 130
and, 6.5x + 11y >1100.
Solving the inequality we get
x= 73.33 and y = 56.667
Now, if they sell at least 90 adult tickets then they sell at most 40 children ticket.
Hence, the solution is (73.33, 56.667).

An air-conditioning and heating company has a fixed monthly cost of $3000. Furthermore, each service call costs the company $20.
Write an equation in slope-intercept form to represent the total cost for 1 month, y, if x service calls are made during the month.
y=
Answer:
For each service call cost of 20$ will be added to fixed cost of 3000$.
Step-by-step explanation:
The total cost for 1 month is the sum of the fixed monthly cost and the cost of all the service calls, so we can write the equation as:
y = 3000 + 20x
This equation is already in slope-intercept form, where "y" is the dependent variable, "x" is the independent variable, 3000 is the y-intercept (the point where the line crosses the y-axis, when x=0), and 20 is the slope of the line.
This equation can be interpreted as

The product of powers property: (a^m) * (a^n) = a^(m+n)The quotient of powers property: (a^m) / (a^n) = a^(m-n)The power of a power property: (a^m)^n = a^(m*n)The product of powers property states that when you multiply two numbers with the same base, you can add the exponents to find the result. For example, (2^3) * (2^4) = 2^(3+4) = 2^7
The quotient of powers property states that when you divide two numbers with the same base, you can subtract the exponents to find the result. For example, (2^5) / (2^3) = 2^(5-3) = 2^2
The power of a power property states that when you raise a power to another power, you can multiply the exponents to find the result. For example, (2^3)^2 = 2^(3*2) = 2^6

The table shows the length and width of proportional rectangles. Length (in inches) 4 6 12 16 width (in inches) 10 15 30 40 using the table, find the width of a rectangle that has a length of 24.
The width of a rectangle that has a length of 24 inches would be 60 inches.
According to the data, we can assume that all the rectangles in the table have the same ratio of measurement.
To find unknown width of the rectangle, we can use this equation:
A/B = C/D
Where:
A represents the length of the first rectangle
B represents the width of the first rectangle
C represents the length of the second rectangle
D represents the width of the second rectangle
In this case, we are going to use 12 as the length of the first rectangle, and 30 as its width.
12/30 = 24/D
12D = (30 x 24)
12D = 720
D = 60
Thus, the width of the rectangle that has a length of 24 inches is 60 inches.

A tunnel is constructed with a semielliptical arch. The width of the tunnel is 70 feet, and the maximum height at the center of the tunnel is 20 feet. What is the height of the tunnel 10 feet from the edge? round your answer to the hundredths place.
Considering the equation of an ellipse, it is found that the height of the tunnel 10 feet from the edge is of 14 feet.
The following is the equation for a horizontal ellipse of center with coordinates (h,k):
(x - h)²/a² + (y - k)²/b² = 1.
In relation to this issue, we have that:
The origin is where the center is.
Since the major axis is 70, 2a = 70 and a = 35.
The maximum height is 20, therefore b is equal to 20.
As a result, the ellipse's equation is as follows:
x²/35² + y²/20² = 1.
It is determined that x = 25 when the tunnel is 10 feet from the edge since 35 – 10 = 25; therefore, the height y is calculated as follows:
25²/35² + y²/20² = 1
0.51 + y²/20² = 1
y²/20² = 0.49
y² = 20² x 0.49
y =√(20² x 0.49)

What is value of x? enter your answer in the box. X = a triangle with vertices labeled as a, b, and c. Side b c is the base. A line segment is drawn from vertex a to base b c that bisects angle b a c into two parts marked with single arcs. Side a b is labeled as 8. Side a c is labeled as 12. Side b c is divided into two equal parts labeled as x plus 4 and 2 x plus 1.
The value of x calculated by using the Pythagorean theorem is equal to 6.
This can be found by using the Pythagorean theorem to solve for the length of side bc, which is the base of the triangle. By using the two given side lengths of 8 and 12, we can find that the length of the hypotenuse (bc) is equal to the square root of 8^2 + 12^2, which is equal to 16.
Since the base is divided into two equal parts, we can divide 16 by 2 and get 8. We then subtract the given length of 2x + 1 from 8 and get 7, which means x is equal to 6.
