Dan's average speed score for the season is -1.

What is the arithmetic operations?

Arithmetic operations are mathematical operations that involve manipulating numbers to perform calculations. The four basic arithmetic operations are addition, subtraction, multiplication, and division.

To find Dan's average speed score for the season, we need to add up all his scores and divide by the total number of scores. We can do this as follows:

-1 + (-3) + 1 + (-1) + (-2) + 0 = -6

Dan's total score for the season is -6. To find his average score, we need to divide this total by the number of scores, which is 6 in this case:

-6 / 6 = -1

Hence, Dan's average speed score for the season is -1.

The answer of the question based on distance and width of the canyon is width of the trapezoid is approximately 67.43 feet.

A trapezoid is  quadrilateral ( four-sided polygon) that has two parallel sides and two non-parallel sides. The parallel sides are referred to as  bases of the trapezoid, while the non-parallel sides are called  legs. The distance between  two parallel sides is called  height or altitude of trapezoid.

The figure in the provided link is a trapezoid with parallel sides AB and CD, and non-parallel sides BC and AD.

Since AB and CD are parallel, we know that the length of the altitude is the same as the distance between them.

Let's call the width of the trapezoid "x". Then, we can use the following equation using the Pythagorean Theorem:

(AC)^2 = (BC)^2 + (AB - CD + 2x)^2

where AC is the diagonal connecting points A and C.

Substituting the given values, we get:

(AC)^2 = (35)^2 + (35 - 80 + 2x)^2

(AC)^2 = 1225 + (2x - 45)^2

(AC)^2 = 1225 + 4x^2 - 180x + 2025

(AC)^2 = 4x^2 - 180x + 3250

Now, we can use the distance formula to find the length of AC:

AC = sqrt[(A - C)^2 + (B - D)^2]

AC = sqrt[(35 + 35)^2 + 80^2]

AC = sqrt[4900 + 6400]

AC = sqrt(11300)

AC = 106.23 feet (rounded to two decimal places)

Substituting the value in  equation above, we will get:

(106.23)^2 = 4x^2 - 180x + 3250

11299.77 = 4x^2 - 180x + 3250

4x^2 - 180x + 8049.77 = 0

Solving the quadratic equation using quadratic formula, we will get:

x = [180 ± sqrt(180^2 - 4(4)(8049.77))] / (2(4))

x = [180 ± sqrt(129322.08)] / 8

x = [180 ± 359.44] / 8

We take the positive root, since x represents a length, and we get:

x = (180 + 359.44) / 8

x = 67.43 feet (rounded to two decimal places)

Therefore, the width of the trapezoid is approximately 67.43 feet.

Answer: The radius of the circle is 5 3/8 inches.

Step-by-step explanation:

The radius of the circle is half of the diameter. We can start by converting the mixed number diameter to an improper fraction:

10 3/4 = (10 × 4 + 3)/4 = 43/4

So, the diameter of the circle is 43/4 inches. The radius is half of this, which we can find by dividing by 2:

r = (43/4) ÷ 2 = 43/8

To simplify the fraction, we can divide the numerator and denominator by their greatest common factor (GCF), which is 1:

r = 43/8 = 5 3/8

Therefore, the radius of the circle is 5 3/8 inches.

Answer:5 3/4

Using linear equations, Tiffany was charged $10.77 for 8 minutes at the self-serve car wash.

Solving a linear equation involves determining the answer to a linear equation with one, two, three, or more variables. The answer to a linear equation is the value or values of the variable(s) that are part of the equation. In the elimination procedure, any coefficient is first made equal, then deleted. After elimination, the equations are solved to provide the other equation.

Given that, the car wash charges $5.25 to use its facilities, plus an additional $0.69 for each minute.

C = 5.25 + 0.69x

For 8 minutes:

C = 5.25 + 0.69(8)

C = $10.77

Hence, Tiffany was charged $10.77 for 8 minutes at the self-serve car wash.

Sketch of  ABC and drawn image after the translation (x,y) (x+4, y + 2) is mentioned below.

In mathematics, translation refers to the process of moving a geometric shape or object from one location to another without changing its size, shape, or orientation. This movement is typically described in terms of the distance and direction of the translation.

For example, a point on a coordinate plane can be translated by adding or subtracting a constant value to its x and y coordinates. Similarly, a line segment or polygon can be translated by moving each of its vertices by the same distance and in the same direction.

Mathematical translations can be represented using transformation matrices or vectors. A translation matrix is a square matrix that describes the movement of a point or object in a specific direction and distance. A translation vector is a one-dimensional vector that describes the direction and distance of the translation.

To sketch the triangle ABC, we first plot the three given points on a coordinate plane:

We connect the three points to form triangle ABC:

    |

 6  |        C(0,5)

    |              /\

 3  |           /    \

    |          /        \

    |        /            \

    |      /                 \

    |    /__________\

    |A(-3,3)       B(1,-1)

    |

    |

    |

    |

    |

    |

        -3     -1    1     3

To find the image of the triangle under the translation (x,y) → (x+4, y+2), we add 4 to the x-coordinates and 2 to the y-coordinates of each point. This gives us the following new coordinates:

A(-3,3) → A'(-3+4, 3+2) = A'(1,5)

B(1,-1) → B'(1+4, -1+2) = B'(5,1)

C(0,5) → C'(0+4, 5+2) = C'(4,7)

We can now plot these new points and connect them to form the image of triangle ABC under the given translation:

    |

 9  |       C'(4,7)

    |             / \

 7  |          /     \

    |         /         \

 5  |      /             \

    |      /                 \

    |    /__________\

 3  |A'(1,5)       B'(5,1)

    |        

    |        

    |        

 1  |

The vertices of the translated figure are A'(1, 5), B'(5, 1), and C'(4, 7).

What is translation?

A translation in mathematics does not turn a shape; instead, it moves it left, right, up, or down. They are congruent if the translated shapes (or the image) seem to be the same size as the original shapes. They have only changed their direction or directions.

To translate the figure by (x+4, y+2), we add 4 to the x-coordinate and 2 to the y-coordinate of each vertex.

So the new coordinates of A' would be -

x-coordinate: -3 + 4 = 1

y-coordinate: 3 + 2 = 5

Therefore, A' has coordinates (1, 5).

The new coordinates of B' would be -

x-coordinate: 1 + 4 = 5

y-coordinate: -1 + 2 = 1

Therefore, B' has coordinates (5, 1).

The new coordinates of C' would be -

x-coordinate: 0 + 4 = 4

y-coordinate: 5 + 2 = 7

Therefore, C' has coordinates (4, 7).

The portfolio weight of Stock A is 0.625 for the given situation.

The percentage of a portfolio's investments that are assigned to each asset or security is shown by the portfolio weights. Investors can meet their chosen risk and return objectives by varying the weights of various assets in their portfolios. Portfolio weights are a key component of asset allocation and portfolio optimization methodologies since they are used to determine the expected return and risk of a portfolio.

Let w be the weight (proportion) of Stock A in the portfolio.

The weight of Stock B would be (1-w).

Given that, the portfolio has an expected return of 10.2 percent.

0.102 = w(0.117) + (1-w)(0.083)

w = (0.102 - 0.083)/(0.117 - 0.083) ≈ 0.625

The equation of the circle x² + y² - 8x - 6y + 16 = 0 in standard form is (x - 4)² + (y - 3)² = 3².

Given the equation of the circle ;

x² + y² - 8x - 6y + 16 = 0

To write the equation of a circle in standard form, we need to express it as:

(x - h)² + (y - k)² = r²

where (h, k) is the center of the circle and r is the radius.

To do this, we need to complete the square for both x and y terms in the given equation.

Starting with the x terms:

x² - 8x = x² - 8x + 16 - 16

= (x - 4)² - 16

Similarly, for the y terms:

y² - 6y = y² - 6y + 9 - 9

= (y - 3)² - 9

Substituting these results into the original equation, we get:

x² + y² - 8x - 6y + 16 = 0

(x - 4)² - 16 + (y - 3)² - 9 + 16 = 0

Simplifying, we get:

(x - 4)² + (y - 3)² - 9 = 0

(x - 4)² + (y - 3)² = 9

So the equation of the circle in standard form is:

(x - 4)² + (y - 3)² = 3²

Answer:

5a + 3b = 13

7a + 6b = 20

And solve for the values of "a" and "b" using algebraic methods like substitution or elimination.

Step-by-step explanation:

Solving for a and b in the system of equations:

5a + 3b = 13

7a + 6b = 20

We can multiply the first equation by 2 to get:

10a + 6b = 26

Then, we can subtract the second equation from this to eliminate b:

(10a + 6b) - (7a + 6b) = 26 - 20

3a = 6

Solving for a, we get:

a = 2

Substituting this value into the first equation, we can solve for b:

5a + 3b = 13

5(2) + 3b = 13

10 + 3b = 13

3b = 3

b = 1

Therefore, the solution to the system of equations is:

a = 2

b = 1.
