Yes, it can be important to look at the increase of wage while working, but that should not be the MOST important thing to look for. In other words, you want to make sure that you are mentally and physically healthy and happy at this job. It will do no good to work as a sluggish and sad worker.

Answer:

7 hamsters at 5 pesos each and 13 hamsters at 8 pesos each

Step-by-step explanation:

5x + 8y = 139

x + y = 20

x = 20 - y

5x + 8y = 139

5(20 - y) + 8y = 139

100 - 5y + 8y = 139

100 + 3y = 139

3y = 139 - 100

3y = 39

3y/3 = 39/3

y = 13

x + y = 20

x + 13 = 20

x = 20 - 13

x = 7

Answer:

For a line to be parallel it must have the same slope. So the slope of the new equation is 6.

The slope intercept form is y=mx+b. And we have a point (3,-5). Plug in what we know....

-5=6(3)+b

Solve for b (the y-intercept)

b= -23

Therefore.... y=6x-23

Step-by-step explanation:

Let's assume that the initial value of the phone is $800, and that its value decreases by 3/5 each year.

After one year, the phone will be worth 2/5 of its initial value:

$800 x (2/5) = $320

After two years, the phone will be worth 2/5 of its value after one year:

$320 x (2/5)^1 = $128

One of the strategies that would eliminate a variable in the system of equations is by subtracting both equations to eliminate the variable "x"

System of equations consists of a different set of equations with unknown variables.

Given the system of equations

2x+3y=-5

2x-3y=10

Since the coefficient of x from both equations are the same, we will subtract both equations to eliminate the variable "x"

(2x-2x)+(3y+3y) = -5 + 10
6y  = 5

Hence we can conclude that one of the strategies that would eliminate a variable in the system of equations is by subtracting both equations to eliminate the variable "x"

the system of equations that represents the situation is:

x + y = 50

2x + 5y = 145

A system of equations is a set of one or more equations that are to be solved simultaneously. The equations in a system share common variables, and the solution to the system is the set of values for those variables that make all the equations in the system true at the same time.

Let x be the number of multiple-choice questions, and y be the number of short answer questions.

The total number of questions is given as 50, so we can write the first equation as:

Step-by-step explanation:

The growth of yeast cultures in a medium typically exhibits logarithmic growth.

In logarithmic growth, the population size increases exponentially over time, meaning that the growth rate is proportional to the current population size.

This results in a characteristic J-shaped curve when the population size is plotted against time.

During the early stages of yeast culture growth, there is a lag phase where the population adjusts to the new environment and begins to adapt and reproduce.

Following this phase, yeast cells enter the exponential or logarithmic growth phase, where the population size increases rapidly.

The growth rate is high during this phase as each yeast cell divides and produces new cells, leading to a doubling of the population within a specific time frame.

Logarithmic growth eventually reaches a stationary phase, where the growth rate slows down, and the population stabilizes.

This occurs when the available nutrients in the medium start to become limited or when waste products accumulate, creating an unfavorable environment for further growth.

Therefore, the growth of yeast cultures in a medium shows logarithmic growth.

Answer:

(a) x + 3(x + 4) = 5(x + 2) - 5

(b) youngest: 7 years old

middle: 9 years old

oldest: 11 years old

Step-by-step explanation:

(a)

We know that x is the youngest child's age. Since the sisters' ages are consecutive odd integers, we know that the ages differ by 2. So, the middle sister's age is x + 2 and the oldest sister's age is x + 4.

Our equation to model the sentence "the sum of the age of the youngest and three times the age of the oldest is five less than five times the middle sister's age" would be:

x + 3 * (x + 4) = 5 * (x + 2) - 5

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

(b)

Now, we can just solve the equation above:

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

x + 3x + 12 = 5x + 10 - 5

4x + 12 = 5x + 5

x = 12 - 5 = 7

So, the youngest sister is 7 years old.

That means the middle sister is 7 + 2 = 9 years old, and the oldest sister is 9 + 2 = 11 years old.

The ages, then, are:

youngest: 7 years old

middle: 9 years old

oldest: 11 years old

Statment b. If you buy groceries for $50, then you PIBP for them is equal to $50 is always true.

PIBP stands for "price paid in buyer's perspective," which means the amount that the buyer pays to purchase a product or service. In this case, if you buy groceries for $50, then your PIBP for them is indeed $50 since that is the price you paid as the buyer.

Option a is incorrect because PISP stands for "price in seller's perspective," which means the value the seller receives in exchange for a deal they own. Option c is incorrect because PIBP stands for "price paid in buyer's perspective," not "value in use."

Using the area of rectangle, the dimensions of the rectangle with maximum area are 5√2 and 5/√2.

In the given question we have to find the dimensions of the rectangle with maximum area.

Given Semicircle Radius is 5.

As we know that standard equation of circle is \(x^2+y^2=a^2\)

a=5, so the equation is \(x^2+y^2=(5)^2\)

\(x^2+y^2=25\)

Therefore, Half circle y=\(\sqrt{25-x^2}\)

Area of Rectangle(A) =xy

Because Half of the rectangle is lies in first quadrant and half lies in second quadrant

Therefore,

Area of Rectangle(A) = 2xy

Now putting the value of y

Area(A) = 2x\(\sqrt{25-x^2}\)

Here we need to maximize the area of Rectangle, so find derivative and set equal to zero.

A'= \(\frac{d}{dx}(2x\sqrt{25-x^2})\)

A'= 2\([x\frac{d}{dx}\sqrt{25-x^2}+\sqrt{25-x^2}\frac{d}{dx}x]\)

A'= 2\([x\cdot\frac{-x}{\sqrt{25-x^2}}+\sqrt{25-x^2}\cdot1]\)

A'= 2\([\frac{-x^2}{\sqrt{25-x^2}}+\sqrt{25-x^2}]\)

A'= 2\((\frac{-x^2+25-x^2}{\sqrt{25-x^2}})\)

A'= 2\((\frac{25-2x^2}{\sqrt{25-x^2}})\)

For critical Number A' = 0

2\((\frac{25-2x^2}{\sqrt{25-x^2}})\) = 0

25-2x^2 = 0

2x^2=25

x^2=25/2

x=±√25/2

x=±5/√2

Therefore,

Base of the Rectangle = 2x

Base of the Rectangle = 2×5/√2

Base of the Rectangle = 5√2

and

height of rectangle = \(\sqrt{25-x^2}\)

height of rectangle = \(\sqrt{25-(5/\sqrt{2})^2}\)

height of rectangle = \(\sqrt{25-(25/2)}\)

height of rectangle = √(50-25)/2

height of rectangle = √25/2

height of rectangle = 5/√2

Hence, the dimensions of the rectangle with maximum area are 5√2 and 5/√2.
