Em 2016 o brasil vendeu para o exterior cerca de 3,5 milhoes de ingressos para espectadores estrangeiros sabendo total de ingressos vendidos é de 7,9 milhoes a quantia de ingressos vendida para a população brasileira foi de? a) 4.050.000 B) 4.400.000 C) 5.000.000 D) 5.500.000
Responder:
4.400.000
Explicação passo a passo:
A quantidade total de ingressos vendidos = 7,9 milhões = 7.900.000
Desse total, o valor vendido ao espectador estrangeiro = 3,5 milhões, = 3,5 milhões
O valor dos ingressos vendidos ao espectador brasileiro será a diferença entre o valor total do ingresso vendido e o total vendido ao espectador estrangeiro.
7.900.000 - 3.500.000 = 4.400.000

Sam is skiing down a mountain. He starts at the peak 97 yards above sea level and skis down the mountain at a rate of 1.5 yards per second. If it takes him 3 minutes to reach flat ground at sea level, what is the measure of the angle that the mountain slope forms with the ground at sea level to the nearest degree?
Answer:
5.2 degrees the mountain slope forms with the ground at sea level
The angle that the mountain slope forms with the ground at sea level is 20.64°
What is speed?"The distance covered by an object in unit time."
What is hypotenuse?"The longest side of a right triangle."
What is sine angle?"In a right triangle for angle θ ,
sin(θ) = opposite side / hypotenuse "
For given example,
Consider the following figure for given example.
Sam starts skiing at the peak 97 yards above sea level.
⇒ XY = 97 yards
He skis down the mountain at a rate of 1.5 yards per second.
⇒ speed = 1.5 yards per second
It takes him 3 minutes to reach flat ground at sea level.
⇒ t = 3 minutes
⇒ t = 180 seconds
XZ is the distance between peak of a mountain and the ground.
Using speed formula,
⇒ speed = XZ / times
⇒ 1.5 = XZ / 180
⇒ XZ = 1.5 × 180
⇒ XZ = 270 yards
This means the hypotenuse of right triangle XYZ is 270 yards.
Now, we need to find the angle that the mountain slope forms with the ground at sea level.
[tex]\Rightarrow sin(\theta)=\frac{XY}{XZ}\\\\\Rightarrow sin(\theta)=\frac{97}{270}\\\\ \Rightarrow sin(\theta)=0.3526\\\\ \Rightarrow \theta = sin^{-1}(0.3526)\\\\\Rightarrow \theta=20.64^{\circ}[/tex]
Therefore, the angle that the mountain slope forms with the ground at sea level is 20.64°

if i made 11$ an hour working at publix how much would i have in 4 year's?
i need to know because me and my friend plan to work at publix as soon as we turn 14 and in 4 year's when we turn 18 we want to have enough to move into an apartment/house right away
Answer:
40*52*11*4 = $91,520
But I am skeptical that you would earn dollars where you would be working... I assume that you do not work in the is because 11 dollars per hour is written at $11/hr not 11$ /hr, thus I assume that you do not live anywhere that pays in U.S. dollars.
Step-by-step explanation:
Answer: $385440 if you work non stop, for every hour of those 4 years
Step-by-step explanation: 24 hours in a day, 24*365=8760
8760*4=35040 total hours.
Now if we multiply that by 11, because you get 11 dollars an hour,
35040*11= $385440 in total
But that's not counting items you may buy, and it also assumes you work every hour of every day. If you want a more realistic amount, you're gonna have to specify the hours that you work.

To find the area of the base, multiply 15 times 16 then divide by 2
Then multiply by 19 to find the volume of the shape
Step-by-step explanation:
The base is a triangle
The area of a triangle = base length times height divided by 2
The triangle has a base length of 16 and a height of 15
So to find the area of the base we multiply 15 times 16 and divide that by 2
The volume of a prism is equal to the area of the base times the length of the prism
The length of the prism is 19 so we would then multiply by 19

Write an expression in simplest form for the perimeter of a right triangle with leg lengths of 12a5 and 9a5.
Given:
The lengths of legs of a right triangle are [tex]12a^5[/tex] and [tex]9a^5[/tex].
To find:
The perimeter of a right triangle.
Solution:
In a right angle triangle,
[tex]Hypotenuse=\sqrt{Leg_1^2+Leg_2^2}[/tex]
[tex]Hypotenuse=\sqrt{(12a^5)^2+(9a^5)^2}[/tex]
[tex]Hypotenuse=\sqrt{144a^{10}+81a^{10}}[/tex]
[tex]Hypotenuse=\sqrt{225a^{10}}[/tex]
On further simplification, we get
[tex]Hypotenuse=\sqrt{(15a^{5})^2}[/tex]
[tex]Hypotenuse=15a^5[/tex]
Now, the perimeter of the triangle is the sum of all of its sides.
[tex]Perimeter=Leg_1+Leg_2+Hypotenuse[/tex]
[tex]Perimeter=12a^5+9a^5+15a^5[/tex]
[tex]Perimeter=36a^5[/tex]
Therefore, the perimeter of the right triangle is [tex]36a^5[/tex].
Are holidays a proper subset of the calendar year?
Select the correct answer below:
No, holidays are only a subset of the calendar year.
Yes, holidays are a proper subset but not a subset of the calendar year.
Yes, holidays are a subset and proper subset of the calendar year.
No, holidays are not a subset or proper subset of the calendar year.
Answer: Choice C
Yes, holidays are a subset and proper subset of the calendar year.
=========================================================
Explanation:
The set of days in the calendar year spans from Jan 1st to Dec 31st.
The set of holidays is a small subset of the previous set mentioned. Any holiday is found on the calendar, but not every day on the calendar is a holiday.
------------
Here's another example of a subset
A = set of all animals
B = set of dogs
Set B is a subset of set A because any dog is an animal. In other words, any individual in set B is also in set A, but not the other way around.
------------
Going back to the calendar example, the set of holidays is a subset and it's also a proper subset of all the days in the year. We say that set B is a proper subset of set A if B has less items in it compared to A.
If we had these two sets
A = {1,2,3,4,5,6}
B = {1,2,3}
We can see that B is a proper subset of set A since everything in B is found in A, and B is smaller than A. The only time we have a subset and not a proper subset is when we talk about the set itself. Any set is a subset of itself (not a proper subset of itself).
The True statement is
Yes, holidays are a subset and proper subset of the calendar year.
What is Set?Sets are represented as a collection of well-defined objects or elements that are consistent from one person to the next. A capital letter represents a set. The cardinal number of a set is the number of items in a finite set.
The order of a set determines the number of elements in the set. It refers to the size of a set. The order of the set is often referred to as the cardinality.
The set of days in the calendar year spans from Jan 1st to Dec 31st.
The set of holidays is a subset of the previously described set. Any holiday can be found on the calendar, however not every day is a holiday.
let Set B is a Proper subset of set A if it contains fewer elements than A.
So, A = {1,2,3,4,5,6}
B = {1,2,3}
We can see that B is a proper subset of set A since everything in B is found in A, and B is smaller than A.
So, holidays are a subset and proper subset of the calendar year.

Answer:
4x² -4xy -4y -4
Step-by-step explanation:
[tex]\boxed{ {a}^{2} - {b}^{2} = (a + b)(a - b)}[/tex]
In this case, a= 2x -y and b= y +2.
(2x -y)² -(y +2)²
= (2x -y +y +2)[2x -y -(y +2)]
= (2x +2)(2x -y -y -2)
= (2x +2)(2x -2y -2)
= 2x(2x) +2x(-2y) +2x(-2) +2(2x) +2(-2y) +2(-2) (expand)
= 4x² -4xy -4x +4x -4y -4
= 4x² -4xy -4y -4
Alternatively, start by expanding the brackets.
[tex]\boxed{(a - b)^{2} = {a}^{2} - 2ab \: + {b}^{2} }[/tex]
[tex]\boxed{(a + b)^{2} = {a}^{2} + 2ab \: + {b}^{2} }[/tex]
(2x -y)² -(y +2)²
= 4x² -4xy +y² -(y² +4y +4)
= 4x² -4xy +y² -y² -4y -4 (expand)
= 4x² -4xy -4y -4 (simplify)

A cell phone company wants to determine the average amount of data that their smart phone customers use each month. Which group would best represent a sample of the population?
one thousand of their customers with the most expensive monthly plans
one thousand of their customers who most recently signed up with the company
one thousand of their customers with a current smart phone data plan
one thousand of their customers who called in for technical support
The group that best represents a sample of the population is one thousand of their customers with a current smart phone data plan.
What is the appropriate sample of the population?
A sample is a smaller representative group of the population. A sample is used as it might not be feasible or cost effective to access the whole population.
The appropraite sample should be representative of the whole population of customers.

Why do we do sampling?We do sampling so that we don't have to work on entire population of items but only on that sample in a way that we can predict information about population.
Most of the times, it isn't possible in real world to work on entire populations. Samples come out for rescue by assumptions that they will have some properties of the population pertained in them.
Thus, the sample should be taken out such that it includes data of the population as much as it can in unbiased way so as to imitate population. (assuming that we want the sample to contain the summary of the population).
We've to collect sample in such a way that we can get a widespread view of the population (all customers). We want to do sampling for getting the average amount of data that their smart phone customers use each month.
Option A, B and D are choosing those customers, which are like a special part of the customers, and not an overall coverage of the customer the cell phone company has.
But option C covers assumingly all sorts of customers who use internet data.
