Answer:
B. 254.3 miles
Step-by-step explanation:
If the plane had to return to the airport making a direct flight, all the 3 distances travelled would make up a triangle as shown in the attachment below.
Let x be the distance to travel back to the airport. This unknown distance (x) can be calculated using the Law of Cosines, which is, a² = b² + c² − 2bc cosA
Where,
a = x
b = 160 mi
c = 150 mi
A = 110.167°
Plug in the above values to solve for x
x² = 160² + 150² - 2(160)(150)*cos(110.167)
x² = 25600 + 22500 - 48000*(-0.345)
x² = 48100 + 16560
x² = 64660
x = √64660
x = 254.28
x ≈ 254.3 miles.
Lucio quiere repartir su colección de estampillas entre la mayor cantidad de amigos pero de manera que todos reciban la misma cantidad tiene parar repartir 30 estampillas de animales 75 estampillas de flores y 160 de ciudades del mundo cuantos grupos iguales puede armar
Answer:
Lucio podrá armar 5 grupos iguales de estampillas.
Step-by-step explanation:
El problema plantea un caso de distribución mediante la aplicación del divisor común mayor a todos los números involucrados. Para ello, primero debemos analizar los divisores de cada uno de estos números:
-30: divisible por 2, 3, 5, 6, 10, 15 y 30.
-75: divisible por 3, 5, 15, 25 y 75.
-160: divisible por 2, 4, 5, 8, 10, 16, 20, 32, 40, 80 y 160.
Así, podemos ver que el divisor común mayor a los tres números es 5, ya que 30, 75 y 160 dan como resultado un número entero tras ser divididos por 5.
Entonces, para poder repartir equitativamente sus estampillas entre la mayor cantidad de amigos posibles, deberá repartir 6 estampillas de animales, 15 estampillas de flores y 32 estampillas de ciudades a 5 amigos. De esta manera, Lucio podrá armar 5 grupos iguales de estampillas.
Suppose you want to learn more about the heights of the buildings in New York City. How would you choose a sample of the buildings? Would your sample be representative of the whole city? Why or why not?
Answer:
I'd use a Non-probability Sampling Method.
Explanation:
The question is already laced with criteria - Heights of Buildings in New York.
This means that there are certain buildings that won't fit in the sample. In a non-probability sample, objects or subjects are elected based on specified criteria that are not random. This means that not all objects/subject have a chance of being included in the sample.
It is assumed that the question/assignment centers around high rise buildings.
Therefore, one storey buildings and bungalows that are within and outside New York will not be included in the sample.
Under the Non-Probability Sampling Method, it is essential to note that there are other subgroupings of sampling techniques. They are:

The mean temperature for the first 7 days in January was 3 °C. The temperature on the 8th day was 5 °C. What is the mean temperature for the first 8 days in January
Answer: 3.25°C
Step-by-step explanation:
From the question, we are given the information that the mean temperature for the first 7 days in January was 3 °C. This means that the total temperature for the first 7 days in January was:
= 3°C × 7
= 21°C
We are also told that the temperature on the 8th day was 5°C. To calculate the the mean temperature for the first 8 days in January, we add the total temperature for the 8 days and then divide by 8.
The total temperature for the 8 days will be: = 21°C + 5°C = 26°C.
The mean temperature for the first 8 days in January will now be:
= 26°C/8
= 3.25°C
Work out the size of angle x: 38° is at the top of the triangle, 101° is at the bottom right of the triangle, work out the size of angle x which is at the bottom left of the triangle.
Answer: x = 41°
Step-by-step explanation:
The sum of the angles in a triangle equals 180°.
To find the missing angle, subtract the sum of the two given angles from 180.
101 + 38 = 139
180 - 139 = 41
x = 41°
The size of the angle at the bottom left of the triangle is 41°.
What is a triangle?A triangle is a geometric figure which has three edges and three vertices. The sum of a triangle's three angles is 180°.
How to solve this problem?Given that the two angles of the triangle are 38° and 101°. We have to find the size of the other angle which is at the bottom left of the triangle. Let the size of the angle be x°.
We have to solve the equation:
x + 38 + 101 = 180
i.e. x = 180 - (38 + 101) = 180 - 139 = 41°
Therefore, the size of the angle at the bottom left of the triangle is 41°.

Answer:
(Option b): segment BC = segment B double prime C double prime over 3
A complete question related to this found at brainly (ID: 13432500) is stated below:
Triangle A″B″C″ is formed using the translation (x + 1, y + 1) and the dilation by a scale factor of 3 from the origin. Which equation explains the relationship between segment BC and segment B double prime C double prime? coordinate plane with triangle ABC at A negative 3 comma 3, B 1 comma negative 3, and C negative 3 comma negative 3
a) segment B double prime C double prime = segment BC over 3
b) segment BC = segment B double prime C double prime over 3
c) segment B double prime C double prime over segment BC = one third
d) segment BC over segment B double prime C double prime = 3
Step-by-step explanation:
Scale factor = 3
∆ABC = original image
∆ABC was dilated to get ∆A"B"C"
∆A"B"C" = new image
DO(x,y) →3(x,y)
To determine which equation explains the relationship between segment BC and segment B"C", first we would find the distance B and C.
Coordinates of ∆ABC
A =(-3, 3)
B= (1, -3)
C= (-3, -3)
The distance B and C = length of Segment BC
the distance between two points = √[(∆x)² + (∆y)²]
= √[(-3-(-3))² + (-3-1)²] = √[(-3+3)² + (-3-1)²]
= √(0+16) = √16 = 4
Length of Segment BC = 4 units
Length of Segment B"C" = scale factor × Length of Segment BC
B"C" = 3 × BC = 3(4) = 12
Since what we need is the equation of the relationship between the segments
B"C" = 3 × BC
BC = B"C"/3
(Option b): segment BC = segment B double prime C double prime over 3
Laboratory tests show that the lives of light bulbs are normally distributed with a mean of 750 hours and a standard deviation of 75 hours. Find the probability that a randomly selected light bulb will last between 825 and 900 hours
Answer:
P(825 to 900 hours) = 0.4772-0.3413=0.1359
Step-by-step explanation:
We are given that the life-span of the bulbs are normally distributed.
First we need to find the z-values, where
z(x)=(x-mean)/standard deviation
=(x-750)/75
therefore
z(825)=(825-750)/75=1
z(900)=(900-750)/75=2
Now we need to find the probabilities of the given z-values, from a probability table or from software.
P(z=1) = 0.3413
P(z=2)=0.4772
So probability that the life-span falls between 825 and 900 hours would be P(825 to 900 hour) = 0.4772-0.3413=0.1359

When using a debit card: A:There are always fees. B:Identification is always required. C:You still need to record transactions in your checkbook. D:You are not personally liable for more than $50 if it is stolen.
Please answer ASAP :)
Answer:
D.
Step-by-step explanation:
Since this isn't a credit card, there are no interests or fees on a debit card, so A is incorrect. B is also incorrect. You only need identification when you are withdrawing or depositing at a bank, but purchases made in stores or online do not need your identification. You also don't need to record transactions in your checkbook (but it is recommend to keep track of purchases). Modern day technology already records transaction history and all you need to do is access it online.
D is correct because if someone steals your PIN for your debit card, they could go to stores and use that money. You can dispute charges and report to the bank if that happens.
Answer:
B
Step-by-step explanation:
When you get a Debit card, you also get a PIN and everytime you make a purchase, you have to use that PIN. C is wrong because Debit is an electronic form of payment and transactions can be viewed online. A is wrong because there aren't always fees. D is wrong because unless you call the bank provider, you will be held liable for every purchase you make.

Find the area of the shaded region. Use 3.14 for pi. Round to the nearest tenth.
r = 15
110
Answer:
110/360=11/36 (I will get back to this)
The area of the circle would be 225 pi using the formula pi r^2. So you multiply 225pi by 11/36 to find the area. This rounds to 215.98
Answer: 490.6
Step-by-step explanation:
There are 360 degrees of a triangle. As 110 degrees are not shaded, you can determine that 250/360, or 25/36 of the degrees in the triangle are shaded. Then simply find the area of the circle by doing πr^2 and getting 706.5. Then simply multiply 706.5 * 25/36 to get 490.625, or 490.6 when rounding to the nearest tenth

Answer:
88 units^2
Step-by-step explanation:
The area of a parallelogram can be found using he following formula:
a=b*h
where b is the base and h is the height.
We know that 11 units is the base and 8 units is the height (forms a right angle with one of the bases).
b= 11 units
h= 8 units
Substitute these values into the formula.
a= 11 units * 8 units
Multiply
a= 88 units^2
The area of the parallelogram is 88 square units.
