Her home is 3km far from the bicycle repair shop;
Her avg speed = 2*6*20/(6+20) = 60/13 km/h
d = r*t = (60/13)*(39/60)
d = 3 km;
What is Avg Speed?
In normal use and in kinematics, the speed (normally known as v) of an object is the significance of the change of its position over time or the value of the change of its role consistent with unit of time; it is for this reason a scalar amount.
The common speed of an item in an c programming language of time is the distance travelled by using the item divided by the length of the c program languageperiod
the instant pace is the restriction of the common speed because the length of the time c program languageperiod methods 0. velocity isn't similar to pace.

A town's population is 42,975 . About 125 people move out of the town each month. Each month, 175 people on average move into town. A nearby town has a population of 45,225. It has no one moving in and an average of 175 people moving away every month. In about how many months will the populations of the towns be equal? Write an equation to model the situation. Then solve the equation and answer the question.
The number of months when they will be equal is 45 months.
How to calculate the equation?The equation for the first town will be:
= 42975 + 125x
The equation for the second town will be:
= 45225 + 175x
The number of months when the populations of the towns will be equal will be:
42975 - 125x = 45225 - 175x
- 125x + 175x = 45225 - 42975
50x = 2250
x = 2250 / 50
x = 45

Do you think it would be better to use breaking apart in the distributive property or compensation to find the product of five times 328? explain why and show how to find the product.
Yes it would be better to use breaking apart in the distributive property or compensation to find the product of 5 x 328 .
what is distributive property?
This property states that multiplying the total of two or more addends by a number will produce the same outcome as multiplying each addend by the number separately and then adding or substracting the results together .like in subtraction A(B-C)= AB-AC
In other words, an equation of the type A (B+C) can be solved as A (B+C) AB+AC in accordance with the distributive property.
This characteristic also holds for subtraction.
5 x 328
= 5(300+28)
= 5 x 300 + 5 x 28
= 1500 + 140
= 1640
Hence, it would be better to use breaking apart in the distributive property or compensation to find the product of 5 x 328 .

Which of the following describes a situation in which the total distance a baseball player travels is zero meters from his starting point? (5 points)
Situation (B) best describes how a baseball player travels a total distance of zero meters from his starting point, that is, the player runs 3 meters forward and then 3 meters in the opposite direction.
What is the distance?Distance is a numerical or quantifiable measurement of the distance between two objects or points. The distance can refer to a physical length or an estimate based on other criteria in physics or everyday usage (e.g. "two counties over"). Because spatial thinking is a rich source of conceptual metaphors in human thought, the term is also frequently used figuratively to mean a measurement of the amount of difference between two common pieces (such as statistical distance between probability distributions or edit distance between text strings) or a degree of detachment (as exemplified by the distance between people in a social network). The concept of a metric space is used in mathematics to formalize most such notions of distance, both physical and metaphorical.According to the options:
Options (A), (C), and (D) is wrong as there the basketball travels some sought distance from the starting point. It is only in option (B) in which the total distance of the baseball player comes to 0 as he runs 3 meters forward and then runs 3 meters in the opposite direction.Therefore, situation (B) best describes that the total distance a baseball player travels is zero meters from his starting point that is, the player runs 3 meters forward and then runs 3 meters in the opposite direction.

The order of the points starting with a and going clockwise around the circle is;
a ⇒ c ⇒d ⇒b
Here,
Four points, a, b, c, and d, lie on a circle having a circumference of 17 units.
b is 5 units counterclockwise from a.
c is 3 units clockwise from a.
d is 11 units clockwise from a and 6 units counterclockwise from a.
We have to find, The order of the points starting with a and going clockwise around the circle.
What is Circumference of circle?
The circumference is the distance around a circle or any curved geometrical shape.
Now,
b is 5 units counterclockwise from a.
b ⇒ a
c is 3 units clockwise from a.
b ⇒ a ⇒ c
d is 11 units clockwise from a and 6 units counterclockwise from a.
d ⇒ b ⇒a ⇒ c ⇒d

The width of a rectangle measures (10p - 9q) centimeters, and its length measures
(7p+8q) centimeters. Which expression represents the perimeter, in centimeters,
of the rectangle?
The expression represents the perimeter, in centimeters, of the rectangle is P = 30q + 2p
Perimeter of a rectangleThe formula for calculating the perimeter of a rectangle is expressed as:
P = 2(l+w)
l = (7p+8q) cm
w = (10p - 9q) cm
Substitute
P = 2(7p+8q+10p-9q)
P = 2(15q+p)
P = 30q + 2p
Hence the expression represents the perimeter, in centimeters, of the rectangle is P = 30q + 2p

This graph represents a quadratic function. What is the function’s equation written in factored form and in vertex form?
The equation of the parabola in vertex form is y + 8 = 2 · (x - 2)². The factored form of the equation of the parabola is y = 2 · x · (x - 4).
What is the equation of the parabola seen in a graph?
Herein we find a representation of a quadratic function on a Cartesian plane, whose formula in vertex form is presented below:
y - k = C · (x - h)²
Where:
(h, k) - Vertex of the parabola.C - Vertex constantBy direct inspection we find that the equation of the parabola has a vertex at (h, k) = (2, - 8) and the point (x, y) = (4, 0). Then, the vertex constant is:
C = (y - k) / (x - h)²
C = (0 + 8) / (4 - 2)²
C = 8 / 4
C = 2
Then, the equation of the parabola in vertex form is y + 8 = 2 · (x - 2)². The factored form of the equation is determined by algebra:
y + 8 = 2 · (x - 2)²
y = 2 · (x - 2)² - 8
y = 2 · (x² - 4 · x + 4) - 8
y = 2 · x² - 8 · x + 8 - 8
y = 2 · x² - 8 · x
y = 2 · x · (x - 4)
The factored form of the equation of the parabola is y = 2 · x · (x - 4).

The three inequalities that satisfies all the points in the unshaded region of the graph of inequalities are;
The three inequalities that satisfies all the points in the unshaded region are;
x ≤ 5y ≤ 102•x + y ≥ 10What are the inequality notation that can be used to represent the unshaded region.1) The inequality that represents the unshaded region to the left of the vertical dashed line at x = 5 is found as follows;
A region to the left of a vertical dashed line in inequality is represented by the less than or equal to symbol, ≤. The region to the right is represented by ≥
The region to the left of the dashed line, x = 5 is therefore;
x ≤ 5.2) The region located below the dashed line y = 10 is represented by the inequality;
y ≤ 103) The slope, m, of the dashed line that extends from point (0, 10) to point (5, 0) is given by the equation;
m = (0 - 10)/(5 - 0) = -2
The equation of the line is therefore;
y - 0 = -2 × (x - 5) = -2•x + 10
y = -2•x + 10
Which gives;
y + 2•x = 10
2•x + y = 10
The inequality that represents the region to the right of the line 2•x + y = 10 is therefore;
2•x + y ≥ 10
