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.

Answer:

Option A

Step-by-step explanation:

Consider the Fibonacci series:

1, 1, 2, 3, 5, 8, 13, 21, 34, 55, ...

Ignore the first 3 terms ( keys)

f(5)/f(4) = 5/3 = ~1.67

f(6)/f(5) = 8/5 = 1.60

f(7)/(f6) = 13/8 = ~1.63

f(8)/f(7) = 21/13 = ~1.61

f(9)/f(8) = 34/21 = ~1.62

f(10)/f(9) = 55/34 = ~1.62

...

=> Option A is the solution

Answer:

The difference in the length of AB and AD is 1.17 units

Step-by-step explanation:

CHECK THE ATTACHMENT FOR FIGURE FOR THE QUESTION

If we study the figure in the attachment , In the ΔABC and ΔADC,

We were given;

x = 45°

y = 63°

AC = 4 units

We will be making use of Sine rule in ΔABC to get our AB side, and we know that in trigonometry, sine rule is an equation that relate the lengths of the sides of a triangle to the sines of its angles.

Sin(B)= Opposite/Hypotenuse

Sin(X) = AC/AB

Sin(45) = 4/AB

Then, Sin(45) * AB = 4

But Sin(45)=1/√2

Then if we substitute the value we have

5.657units

Hence, AB= 5.657units

We can also make use of by sine rule in ΔADC to get our AD side

Sin(y)° = AC/AD

Sin(63) = 4/AD

Sin(63)× AD= 4

AS= 4.489 units

Hence AD= 4.489 units

To calculate the difference in the length of AB and AD, we will need to substract side AD from AB; which is

AB - AD = 5.657 - 4.489

= 1.168

= 1.17 units ( if we approximate)

Hence, the difference in the length of AB and AD would be 1.17 units

Given question is incomplete without the figure; find the figure attached.

 Difference in the lengths of AB and AD is 1.17 units.

    Given in the question,

Apply sine rule in ΔABC,

sin(x°) = [tex]\frac{AC}{AB}[/tex]

sin(45°) = [tex]\frac{4}{AB}[/tex]

AB = 4√2

AB ≈ 5.657

Similarly, apply sine rule in ΔADC,

sin(y°) = [tex]\frac{AC}{DC}[/tex]

sin(63°) = [tex]\frac{4}{AD}[/tex]

AD = 4.489

Now difference in lengths of AB and AD = 5.657 - 4.489

                                                                    = 1.168

                                                                    ≈ 1.17

    Therefore, difference in the lengths of AB and AD will be 1.17 units.

Answer:

a) 2

b) .05

c) 6.07

d) 0.002

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:

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.

Answer: C

Step-by-step explanation:

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°.

A triangle is a geometric figure which has three edges and three vertices. The sum of a triangle's three angles is 180°.

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:

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:

(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

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

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

Answer:

No. of ticket bought is 4

Step-by-step explanation:

Let the no. of ticket bought be x

Given cost of 1 ticket = $12

Therefore cost x ticket = x*cost of 1 ticket = x*$12 = $12x

parking fee = $5

given that it is flat so, whatever be the no. of ticket bought or family member,

the parking cost will remain $5 only.

Total money paid by family  = parking charge + cost x ticket = 5+12x

But , given that family paid total of $53

then

5 + 12x = 53

=> 12x = 53-5 = 48

=> x = 48/12 = 4

Thus, no. of ticket bought is 4.

This can be validated as  shown below

cost of 4 ticket as 12 each will be = 12*4 = 48

thus total money paid = $(48+5 )= $53

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
