Answer:
Step-by-step explanation:
Since the sum of all interior angles of a triangle is 180 degrees, we are able to derive the answer of what x (m<1 in this case) measures.
For example, in number 1, you can do
m<1 = 180 - 94 - 45
For the 2nd one, the tick marks show that the highlighted angles measure the same.
So, it would be (180-58)/2 = m<1
Finally, for the third one, there is a right angle, meaning that it measures 90 degrees
Therefore, 180-90-77 = m<1
When buying tickets to a play online, they cost $12.75 per ticket plus a $12 fee per order. When buying tickets at the box office, they cost $15.75 per ticket. The total cost, c, of n people buying tickets for the play using either method to purchase tickets can be represented by an equation. Write the system of equations. Choose the correct answer below.
Answer:
c = 12.75n + 12
c = 15.75n
Step-by-step explanation:
Let
c = total cost of the ticket
n = number of people buying tickets
Buying tickets online
c = 12.75n + 12
Buying from the box office
c = 15.75n
This can be represented by the system of equation:
c = 12.75n + 12
c = 15.75n

Un dirigible que está volando a 800 m de altura, distingue un pueblo con un ángulo de depresión de 12°. ¿A qué distancia del pueblo se halla?
Answer:
3764 m
Step-by-step explanation:
Resolvemos usando la función trigonométrica de tangente.
tan θ = Opuesto / Adyacente
θ = Ángulo de depresión = 12 °
Opuesto = 800m
Adyacente = Distancia de la ciudad = x
Cruz multiplicar
bronceado 12 = 800 / x
Cruz multiplicar
bronceado 12 × x = 800
x = 800 / tan 12
x = 3763.7040876 m
Aproximadamente = 3764 m

The population of a certain city be modeled by y=7870(1.01)^x where x is the number of years since the city was founded and y is the population.
Answer:
B.
Step-by-step explanation:
We are given the function:
[tex]y=7870(1.01)^x[/tex]
Which represents the population of a certain city x years after it was founded.
The y-intercept is the y-value when x = 0. So:
[tex]y(0)=7870(1.01)^0=7870(1)=7870[/tex]
If x = 0, this means that zero years have passed since the city was founded.
So, the y-intercept represents the initial amount of people when the city was founded (in this case, there were 7870 people).
The correct answer is B.

y = - 2 x + 2
y = 2 x - 2
y = 2 x + 2
Answer:
y = 2x + 2
Step-by-step explanation:
The general form
is;
y = mx + b
where m is the slope and b is the y-intercept
so we have;
y = mx + 2
To get m, substitute the point (-1,0)
So we have
0 = -m + 2
m = 2
So the equation is;
y = 2x + 2

How many solutions does this system of linear equations have? Explain. 3y + 6x = 12 8x + 4y = 16
Answer:
first equation : 3y + 6×=12
second equation : 4y + 8x = 16
Step-by-step explanation:
first equation
3y + 6× = 12
now take the common ,
3( y + 2x ) = 12
so, y + 2x = 4
second equation
4y + 8x = 16
4 ( y + 2x ) = 16
so, y + 2x = 4

A self-tanning lotion advertises that a 4 -oz bottle will provide seven applications. Jen found a great deal on a 13 -oz bottle of the self-tanning lotion she had been using. Based on the advertising claims, how many applications of the self-tanner should Jen expect?
Answer:
22.75 applications
Step-by-step explanation:
From the above question, we understand that:
4 -oz bottle = 7 applications
13 -oz bottle = x applications
Cross Multiply
4 -oz bottle × x applications = 13 -oz bottle × 7 applications
x applications = 13 -oz bottle × 7 applications/4 -oz bottle
x applications = 22.75 applications
Therefore, the number of applications of the 13 -oz bottle self-tanner that should Jen expect is 22.75 applications.
The number of applications that Jen can expect from the self-tanner is 22.75 applications.
The first step is to determine how many applications 1 -oz of the bottle can provide.
Number of applications 1 -oz of the bottle can provide = 7/4 = 1.75
The second step is to multiply the figure gotten in the previous step by 13
13 x 1.75 = 22.75 applications
