Answer:
50Step-by-step explanation:
Given
Distance covered by the bird = 400km
Time taken = 8 hours
Using the formula;
Speed = Distance/Time
S = d/t
Find the speed first:
S = 400km/8hr
S = 50km/hr
Substitute back into the formula:
S = d/t
50 = d/t
50t = d
d = 50t
This means that the distance d is directly proportional to the time with 50 as the constant of proportionality.
Hence the constant of proportionality for the relationship between distance in kilometers is 50.
which statements about the trend line in item 3 are true? select all that apply.
a. the slope is the cost of one book
b. the slope is the cost if Hana's lunch
c. the y-intercept is the cost of one book
d. the y-intercept is the most if Hana's lunch
Answer: A and D
Step-by-step explanation:
I took the test online and the answer is A and D the y intercept is the cost of her lunch and the slope is the cost of one book
The true statements are the slope is the cost of one book and the y-intercept is the cost if Hana's lunch.
What is Slope?A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the
change in y coordinate with respect to the change in x coordinate as,
m = Δy/Δx where, m is the slope
Given:
as, from the graph the slope tells us about the cost of one book.
Now, From the graph if we talk about y- axis then we can see that the y- axis tells us about cost if Hana's lunch.
Hence, the true statements are the slope is the cost of one book and the y-intercept is the cost if Hana's lunch.

Answer:
13(10) - 5 (6)
130 - 30
= 100
Step-by-step explanation:
You replace the x with 10, and the y with 60 and answer normally
13(30) = 130

The total operating cost to run the organic strawberry farm varies directly with its number of acres. What is the constant of variation in this scenario?
Answer: 16 acres
Step-by-step explanation: we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form or
In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin
Let
x ----> the number of acres
y ---> total operating costs
we have the ordered pair (20,551,520)
For x=20 acres, y=$551,520
Find the value of the constant of proportionality k
substitute the values of x and y
The linear equation is equal to
Find out how many acres are on a farm with a total operating cost of $441,216
so
For y=$441,216
substitute in the linear equation the value of y and solve for x

Find the inverse for this relation: { (1, -3), (-2, 3), (5, 1), (6, 4) }
Answer:
(-3,1), (3,-2), (1,5), (4,6)
Step-by-step explanation:
For finding and inverse of a relationship, you simply just need to swap the x and y values. So the x will go into the y value and the y value will go into the x value.
The inverse relation for the given relation is {(-3, 1), (3, -2), (5, 1), (6, 4)}.
What is relation?A relation in mathematics can be defined as a set of a pair of elements belonging to each set. It is also called as a mapping from one set to the other.
The given relation is { (1, -3), (-2, 3), (5, 1), (6, 4) }.
The domain of the given relation is set of all the first elements of each pair and the range is the set of all the second elements of each pair.
The range and domain set can be written as,
Domain = {1 , -2, 5, 6 }
Range = {-3, 3, 1, 4}
In order to find the inverse relation the domain and range sets sre interchanged.
Thus, the inverse relation for the given relation can be written as,
{(-3, 1), (3, -2), (5, 1), (6, 4)} .
Hence, the inverse relation is given as {(-3, 1), (3, -2), (5, 1), (6, 4)}.

Monica uso 1,2 litros de leche para hacer 12 flanes iguales ¿cuantos litros de leche necesitaria para hacer 60 flanes? ¿cuantos flanes haria con 0,5 decalitros de leche?
Answer:
1. 6 L de leche.
2. 50 flanes.
Step-by-step explanation:
1. Determinación del volumen (en litros) necesario para realizar 60 natillas.
De la pregunta dada arriba,
Monica usó 1.2 L de leche para hacer 12 natillas iguales.
Por lo tanto, usará xL de leche para hacer 60 natillas, es decir
xL de leche = (1.2 × 60) / 12
xL de leche = 6
Por lo tanto, necesitará 6 L de leche para hacer 60 natillas.
2. Determinación del número de flanes (natillas) que se pueden producir utilizando 0,5 decalitros de leche.
Empezaremos por convertir 0,5 decalitros (deca) a litro (L).
Esto se puede obtener de la siguiente manera:
1 deca = 10 L
Por lo tanto,
0.5 deca = 0.5 deca × 10 L / 1 deca
0,5 deca = 5 L
Por tanto, 0,5 deca equivale a 5 L.
Finalmente, determinaremos el número de flanes (natillas) que se pueden obtener a partir de 0.5 deca (es decir, 5 L) como se muestra a continuación:
Monica usó 1.2 L de leche para hacer 12 natillas iguales.
Por lo tanto, usará 5 L de leche para producir = (5 × 12) /1.2 = 50 natillas
Por lo tanto, puede hacer 50 flanes (natillas) usando 0.5 deca (es decir, 5 L).

Your friend, Broseph, recently graduated from the University of Bros. During his last semester he passed "Introduction to Brotistics with an Emphasis on Tinder Applications". His final project required that he use the Binomial Distribution to calculate the probability of going on a date with more than half of his next 20 Tinder matches.
Broseph found that he had a 64% chance of going on a date with any given Tinder match from historical data.
Broseph should use the ____________ to calculate the probability. Since he is calculating the probability of going on dates with more than half of his next 20 matches--the number of successes is ________ , n = ________ , and p = ______ .
Broseph has a __________ chance of going on dates with at least half of his next 20 Tinder matches. Round the answer to nearest tenth as a percentage i.e. 14.2%.

The total price of apples (y) at an orchard can be calculated with the equation y=1.25x+5, where x is the number of pounds of apples picked. What does the slope represent?
Given:
The total price of apples (y) at an orchard can be calculated with the equation
[tex]y=1.25x+5[/tex]
where, x is the number of pounds of apples picked.
To find:
The interpretation of slope for the given situation.
Solution:
The slope intercept form is
[tex]y=mx+b[/tex] ...(i)
where, m is slope and b is y-intercept.
We have,
[tex]y=1.25x+5[/tex] ...(ii)
On comparing (i) and (ii), we get
[tex]m=1.25, b=5[/tex]
Slope = 1.25.
We know that, y is total price of x pounds of apples picked and slope is change in y with respect to x.
Therefore, the slope of the given equation is 1.25 and it means the price increased by 1.25 for each additional pounds of apples.
solve nt+6-xt=s for t

Step-by-step explanation:
[tex]nt+6-xt=s[/tex]
[tex]\mathrm{Subtract\:}6\mathrm{\:from\:both\:sides}[/tex]
[tex]nt+6-xt-6=s-6[/tex]
[tex]Simplify[/tex]
[tex]nt-xt=s-6[/tex]
[tex]nt-xt[/tex]
[tex]=t\left(n-x\right)[/tex]
[tex]t\left(n-x\right)=s-6[/tex]
[tex]\frac{t\left(n-x\right)}{n-x}=\frac{s}{n-x}-\frac{6}{n-x};\quad \:x\ne \:n[/tex]
[tex]t=\frac{s-6}{n-x}[/tex]

What is Mathematical function ?
Function is defined as the expression or relation between any given two variables such as x and y and there must be an independent variable and dependent variable.
In other words the function represents the graph between x and y that is for each value of x there exist one value of y but here there is no restriction in values of y that is y can have infinity values.
Given equation is nt+6-xt=s
Now solving for t by separately variables and constant :
nt+6-xt=s
t(n-x) = s-6
t = (s-6)/(n-x)
Therefor the value of t after arrangement is t = (s-6)/(n-x)

Jordan signed up for the Annual Cross Florida bike ride which is a 170 mile bike ride. After weeks of training he rides at an average of 15 miles per hour. What is x in real world context?
Answer: 11.3 hours
Step-by-step explanation:
Before this question is another asking for an equation depicting this with Jordan's progress in miles (y) after a number of hours (x).
That would be y = 15x
x in the real world context would be the number of hours it would take for Jordan to finish the 170 mile bike race.
To solve this make y to be 170 and solve for x.
170 = 15x
x = 170/15
x = 11.3 hours
(1.8 x 10°) (6.7 x 1012)
