Answer:

1). Option E

2). Option H

3). Option C

4). Option J

5). Option C

Step-by-step explanation:

1). (5x + 3xy + 4y) + (4x - 2xy - 2y)

= (5x + 4x) + (3xy - 2xy) + (4y - 2y)

= 9x + xy + 2y

Option E. is the answer.

2). 5y + 2z + 3x²- (2y - 2z + 4x)

= 5y - 2y - 4x + 2z + 2z + 3x²

= 3y - 4x + 4z + 3x²

Option H is the answer.

3). (x - 1)(x + 1)(x - 1)

= (x² - 1)(x - 1)    [Since (a - b)(a + b) = a² - b²]

= x²(x - 1) - 1(x - 1)

= x³ - x² - x + 1

Option C is the answer.

4). (2a + 6)²

= 4a² + 24a + 36

[Since (a + b)² = a² - 2ab + b²]

Option J. is the answer.

5). For subtraction,

(6 - 1)³ - (4 - 1)²

= 5³ - 3²

= 125 - 9

= 116

But the result is 200 so operation subtraction is not the answer.

For Multiplication,

(6 × 1)³ - (4 × 1)²

= 6³ - 4²

= 216 - 16

= 200

For division,

(6 ÷ 1)³ - (4 ÷ 1)²

= 6³ - 4²

= 216 - 16

= 200

Therefore, Option C. is the answer.

Answer:

Step-by-step explanation:

15 people can be served because a liter equals to 1000 milliliters and that means that 7 times two equals 14 plus the other 500 milliliters then that's 15.

15 people can get water before the cooler is empty.

In order to find the number of people who would be able to get water before the cooler empties, you need to divide the total quantity of water in the cooler by the quantity given to each person.

To do that, both quantities have to have the same unit. The liters should therefore be converted to milliliters.

1 liter = 1,000 milliliters

7.5 liters = 7.5 x 1,000

= 7,500 milliliters

The number of people that would get a drink is:

= Quantity of water in cooler / quantity of water per person

= 7,500 / 500

= 15 people

Answer: Jane started growing Sphere 3 hours ago

Step-by-step explanation:

Farm Rod starting population (Rsp) = 2

Farm Sphere starting population (Ssp) = 8

Let´s name "Rh" the quantity of hours since Rod started growing, and

"Sh" the quantity of hours since Sphere started growing.

And, let´s name "R" the population of farm Rod at 8 p.m. and "S" the population of farm Sphere at 8 p.m.

Population of Rod doubles every hour, therefore:

R = [tex]Rsp * 2^{Rh}[/tex]

R = [tex]2(2^{Rh})[/tex]

Population of Sphere is quadrupled every hour, therefore:

S = [tex]Ssp * 4^{Rh}[/tex]

S = [tex]8(4^{Rh})[/tex]

At 8 p.m. Jane found that R = S

Therefore, at 8 p.m:

[tex]2(2^{Rh})[/tex] = [tex]8(4^{Sh})[/tex]

dividing both sides by 2

[tex]2^{Rh} =4(4^{Sh})[/tex]

adding exponents

[tex]2^{Rh} = 4^{Sh+1}[/tex]

[tex]2^{Rh} =2^{2^{Sh+1} }[/tex]

the bases are the same; exponents must be the same

Rh = 2Sh + 2    (equation 1)

And we also know that Jane started growing Rod five hours before Sphere:

Rh = Sh + 5    (equation 2)

Replacing equation 2 into equation 1:

(Sh + 5) = 2Sh + 2

5 - 2 = 2Sh - Sh

3 = Sh, or

Sh = 3

Answer:

It can be any digit between 7, 8 and 9.

Step-by-step explanation:

The given data set is: 2​, 4​, 5​, 7​, 7​, 10

Here mode is 7, So we have to make our median equal to 7.

If one more data point will be included in the data set then we will have an odd number of observations.

For getting a median equal to 7 we have to add a number between 7 and 10 or it can be equal to 7.

Now, if we add any data points between 7, 8 and 9 then our median and mode will equal to 7.

Hence, the any one number between 7, 8 and 9 can be included in given data set to get both median and mean equal.

Further, the Median is the middle observation of the given data. It can be found by following steps:

Arranging data in ascending or descending order.

Taking the average of the middle two values if the total number of observations is even, and this average is our median.

or, if we odd number of observation then the most middle value is our median.

The mode is the observation which has a high number of repetitions (frequency).

The entry that should be added to the data set 2, 4, 5, 7, 7, and 10 to make the median and mode equal is 7. This is because the current mode is 7, and to have the median also equal to 7, a 7 must be added to the data set.

The goal is to add an entry between 1 and 10 to your data set (which currently includes 2​, 4​, 5​, 7​, 7​, and 10) that will make the median and mode equal. To start, let's understand what the median and mode are. The median is the middle value in an ordered data set. If there's an even number of values in the set, the median is the average of the two middle values. The mode, on the other hand, is the most frequent value or values in a data set.

In your original data set, the mode is 7, as it appears twice. Currently, with six numbers in the data set, the median would be the average of the 3rd and 4th numbers when ordered (5 and 7), so the median is 6. To match the mode (7), a 7 needs to be added to the data set. Now the median is (7 + 7) / 2 = 7, which matches the mode of 7. So, the number you need to add to your dataset to make the median and mode both equal 7 is 7.

Step-by-step explanation:

The question in English is

An expanding mobile phone company handled eight hundred and fifty thousand calls a day during the quarter. In the next quarter it expects to reach one million and increase quarterly by the same amount over the next two years. How many daily calls do you expect to handle in two years?

Let

Answer: All data will be sent in 89.39 hours

Step-by-step explanation:

Data transfer rate: 100 Mbps=100 [tex]\frac{Mb}{s}[/tex] ×[tex]\frac{1Tb}{1024^{2} Mb}[/tex]×[tex]\frac{3600s}{h}[/tex]=0.3433 [tex]\frac{Tb}{h}[/tex]

The pigeon can fly 1000 km/day and it needs to fly 400 km (round trip).

Pigeon rate: [tex]\frac{1000km}{24h}[/tex]=41.67 [tex]\frac{km}{h}[/tex]

Time of round trip: 400 km÷[tex]\frac{1000km}{24h}[/tex]=9.6 h

So the pigeon can send 1 Tb every 9.6 hours.

If we sum the rates we can get the time for sending all the data:

Step-by-step explanation:

Let x represent the number of trout in the lake.

We have been given that a group of naturalists catch, tag and release 121 trout into a lake. The next day they catch and release 48 trout, of which 22 had been tagged.

Using proportions, we will get:

[tex]\frac{\text{Total trouts}}{\text{Tagged trouts}}=\frac{48}{22}[/tex]

[tex]\frac{x}{121}=\frac{48}{22}[/tex]

[tex]\frac{x}{121}*121=\frac{48}{22}*121[/tex]

[tex]x=\frac{24}{11}*121[/tex]

[tex]x=24*11[/tex]

[tex]x=264[/tex]

Therefore, there would be approximately 264 trout in the lake.

264 trouts are estimated to be in the lake.

Using proportion, we write: Tagged trout/Total Trout

This becomes 22/48.

In order to use cross multiplication, we write another fraction using x, the total number of trout in the lake: 121/x.

Now we have 121/x=22/48.

We cross multiply.

121*48=22x.

(121*48)/22 becomes:

1 pound = 0.454 kilograms

1 ounce = 0.0296 liters

1 ounce = 0.0283 kilograms

Step-by-step explanation:

You need to convert the quantities to their corresponding unit.

Convert pounds to kilograms (For the entrecote)

1 pound = 0.454 kilograms

Thus, 1 pound of entrecote = 0.454 kilograms

Ounces to liters (for the Béarnaise, since it is a liquid)

1 ounce = 0.0296 liters

2 ounces of Béarnaise = 0.0592 liters

Ounces to kilograms (for the asparagus)

1 ounce = 0.0283 kilograms

4 ounces of asparagus =0.1132 kilograms

By using unit conversion and dimensional analysis, the 1 pound of entrecôte converts to roughly 0.4536 kg, 2 ounces of Béarnaise to around 56.7 grams, and 4 ounces of asparagus to approximately 113.4 grams.

The answer to your question is: d = √73  

Step-by-step explanation:

data

Point E (-3, 4)

Point F (5, 1)

Formula

d = √((x2-x1)² + (y2-y1)²)

d = √(5-(-3))² + (1-4)²)          substitution

d= √ (5+3)² + (-3)²               simplify

d= √ 8² + -3²

d = √ 64 + 9

d = √73                               result

The distance between points E(5,1) and F(-3,4) in coordinate geometry is calculated by using the distance formula derived from the Pythagorean theorem. The computed distance between points E and F comes out to be √73 units.

The subject of this question is the distance formula in coordinate geometry, specifically between two points E(5, 1) and F(-3, 4). The formula is derived from the Pythagorean theorem and is represented as: D = √[(x₂ - x₁)² + (y₂ - y₁)²]. It is used to determine the simplest distance or 'path' between two points in a coordinate plane.

distance = √((x2 - x1)^2 + (y2 - y1)^2)

Substituting the coordinates of E and F, we have:

distance = √((-3 - 5)^2 + (4 - 1)^2)
distance = √((-8)^2 + (3)^2)

distance = √(64 + 9)

distance = √73

So, the exact distance between point E and point F is approximately √73 units.

The cheapest cost to fill the Paolo's tank = $33.75

We have Paolo who bought a used car for $3,500 and wants to fill it up with gasoline. His gas tank holds 15 gallons and is currently empty. Paolo has $100. One gas station sells gas for $2.50 per gallon. The station across the street sells gas for $2.25 per gallon.

We have to determine the cheapest cost to fill up Paolo's tank.

The price estimation is important in mathematics as it helps us to create mathematical relations among the various factors on which the price depends in order to extract accurate results.

According to question, we have -

Cost of Car = $3500.

Car's gasoline capacity = 15 gallons.

Amount of money with Paolo = $100.

Cost of gas at station A = $2.25.

Cost of gas at station B = $2.50.

Case 1 - If Paolo goes to Station A

Total cost to fill the tank = 2.25 x 15 = $33.75

Case 2 - If Paolo goes to Station B

Total cost to fill the tank = 2.50 x 15 = $37.50

Hence, the cheapest cost to fill the Paolo's tank = $33.75

Answer:

There are 49 corrupt senators and 1 honest senator.

Step-by-step explanation:

Freedonia has 50 senators. Each senator is either honest or corrupt. At least one of the Freedonian senators is honest.

As we can see that there are no two senators where both of them are honest. So either there is one senerator who is honest or none.

As given that at least one of the Freedonian senators is honest.

Hence, we can conclude there is one and only one honest senator.

Final answer:

In Freedonia's senate, there must be one honest senator and forty-nine corrupt senators to satisfy the given conditions.

Explanation:

To solve the problem presented, we must work under the conditions that in Freedonia's senate of 50 senators, which implies that there are 50 senators in total, each is either honest or corrupt, at least one senator is honest, and in any pair of senators, at least one is corrupt. This means it's impossible to have two honest senators together, as this would contradict the condition that in any pair of senators, there must be at least one corrupt senator.

Given that there is at least one honest senator, we can use logic to deduce the following: If we were to assume that there are two honest senators, we would have a pair of senators where both are honest, which violates the given condition. Therefore, there can be only one honest senator in Freedonia's senate to meet all the conditions laid out in the problem.

Since the total number of senators is 50, and we have established that there is only one honest senator, it follows that the remaining 49 senators must be corrupt. Hence, the Freedonia's senate consists of one honest senator and forty-nine corrupt senators.

[tex]When\ y\geq 0 => | y | = y[/tex]

y - 19 = -15

y = 19 - 15

y = 4

Case 2: [tex]y< 0[/tex]

[tex]When\ y < 0 => |y| = -y[/tex]

-y -19 = -15

-19 + 15 = y

-4 = y

Both are solutions of the equation.

Answer:

-4, 4 would be your answer
