Happy Paws charges $18.00 plus $4.50 per hour to keep a dog during the day. Woof Watchers charges $12.00 plus $5.75 per hour. Complete the equation and solve it to find for how many hours the total cost of the services is equal. Use the variable h to represent the number of hours. The equation is . The total cost of the services will be equal at hours.

HELP ME PLEASE!

Answers

Answer:

This is just a basic mathematical function in which 18.00$ is the starting cost of Happy Paws service and they charge 4.50$ an hour, and we can represent this with [tex]18.00$ + 4.50h = C[/tex].

C is the total cost and h represents the number of hours that took place.

Now looking at Woof Watchers, the starting cost is 12.00$ and they charge 5.75$ an hour, we can also represent this with the equation [tex]12.00 +5.75h=C[/tex].

Now we can figure out the answer the long way or the short way.

The short way is a lot more simple, so I will use that.

The short way is plugging these equations into a graphing calculator.

After that, the number of hours they both babysit to have equal total costs is 4.8 hours or 4 hours and 48 minutes, and the total cost for both services after 4.8 hours will be approximately 40$ or to be exact, 39.60$

The proportional equation that is on the graph can be written as:

y = 0.83*x

How to find the graphed proportional equation?

Remember that a general proportional equation is written as:

y = k*x

Where k is the constant of proportionality.

To find the value of the constant of proportionality, we need to identify one point that lies on its graph. For example, we could use the point (0.6, 0.5)

Where x = 0.6

y = 0.5

Replacing that in the general proportional equation we will get:

0.5 = k*0.6

0.5/0.6 = k

0.83 = k

Then the proportional equation is:

y = 0.83*x

Step-by-step explanation:

The imaginary variable i is [tex]\sqrt{-1}[/tex] and [tex]i^2 = -1[/tex]

For the unnumbered first question we have

the equation
[tex]\dfrac{1}{1-i}[/tex]

Multiply numerator and denominator by [tex]i + 1[/tex]

[tex]\rightarrow \dfrac{1\cdot \left(1+i\right)}{\left(1-i\right)\left(1+i\right)}\\\\\\= \dfrac{1 + i}{1 - i^2} \;\;\;\;\;\;\;since \;(a +b)(a-b) = a^2 - b^2\\\\\textrm{Since $i^2 = -1$, the denominator becomes:}\\\\1-i^2 = 1 -(-1) = 2\\\\\\[/tex]

Therefore ,

[tex]\dfrac{1}{1-i} = \dfrac{1 + i}{2}\\\\= \dfrac{1}{2} + \dfrac{i}{2}\\\\[/tex]

Find Dy/Dx By Implicit Differentiation. 5x^2-xy-4y^2=0

Answers

The Implicit Differentiation of 5x^2-xy-4y^2=0 is Dy/Dx= (5x-y)/(-4y)

Using implicit differentiation, Dy/Dx can be found by taking the derivative of both sides with respect to x.

On the left side, the derivative with respect to x of 5x2 is 10x and the derivative with respect to x of -xy is -y.

On the right side, the derivative of 4y2 with respect to x is 0.

Therefore, the equation becomes 10x - y = 0.

Solving for y gives y = 10x.

Substituting this into the original equation, we get 5x2 - 10x2 - 4(10x)2 = 0, which simplifies to -5x2 - 40x2 = 0.

Finally, we can solve for Dy/Dx:

Dy/Dx= (5x-10x)/(-4(10x))

Dy/Dx= (5x-y)/(-4y)

Find the volume of a pyramid with a square base, where the area of the base is 4. 6\text{ cm}^24. 6 cm 2 and the height of the pyramid is 2. 3\text{ cm}2. 3 cm. Round your answer to the nearest tenth of a cubic centimeter.

Answers

The volume of the pyramid is 3.5 cubic centimeters.

The volume of a pyramid can be calculated using the formula:

V = (1/3) * Base area * Height

Where Base area is the area of the base of the pyramid, and Height is the distance from the base to the apex of the pyramid.

Given that the area of the base of the pyramid is 4.6 cm^2 and the height of the pyramid is 2.3 cm, we can substitute these values into the formula and solve for the volume:

V = (1/3) * 4.6 cm^2 * 2.3 cm = 3.53 cm^3

So the volume of the pyramid is 3.53 cubic centimeters. Rounded to the nearest tenth of a cubic centimeter, the volume is 3.5 cm^3.

Help find the perimeter

Answers

Answer:

Step-by-step explanation:

As 9: 16.2

Then 6: EF   Lets take EF as side x

9:16.2 as

6:x    CROSS MULTIPLY ( 9×x and 16.2×6)

Cross multiplying gives you: 9x and 97.2

Then divide both answers by 9 ( 97.2÷9 and 9x÷9)

This gives you x=10.8 which is side EF

To find side AB ADD 9 and 6 to get 15 and subtract this from 36 and you get 21.

Using the same method to find EF find DE and you will get 37.8

Therefore, perimeter becomes:

16.2 + 37.8 + 10.8 = 64.8

HOPE THIS HELPS

Answer:

P△DEF=64,8

Step-by-step explanation:

P△ABC=36, AC=9, BC=6 → AB=21

AC/DF=9/16,2; AB/DE=21/DE ⇒ DE=(21*16,2)/9=37,8

AC/DF=9/16,2; BC/EF=6/EF ⇒ EF=(6*16,2)/9=10,8

P△DEF=16,2+37,8+10,8=64,8

x = 7, y = 33 satisfies the equation , that is

33 = 7a + 5 ( subtract 5 from both sides )

28 = 7a ( divide both sides by 4 )

4 = a

then

y = 4x + 5 ← top equation

substitute y = 4x + 5 into the other equation

9x + 2(4x + 5) = 44

9x + 8x + 10 = 44

17x + 10 = 44 ( subtract 10 from both sides )

17x = 34 ( divide both sides by 17 )

x = 2

What is the greatest common factor of 10 and 4x?

Answers

The GCF of 10 and 4x is 2.

The greatest common factor (GCF) of two or more numbers is the largest number that divides evenly into each of them. Factoring a number means breaking it down into its prime factors. That is;

10 = 2 * 5 , we can see that 2 and 5 are the prime factors of 10.

4x = 4 * x, we can see that 4 and x are the prime factors of 4x.

Since 2 is the only common factor between 10 and 4x, we can conclude that 2 is the GCF of 10 and 4x.

It means that 2 is the greatest number that divides into both 10 and 4x with a remainder.

Therefore, the GCF of 10 and 4x is 2.

What is Quadrilateral?

•A polygon called a quadrilateral has four sides, four angles, and four vertices. Parallelograms, Squares, Rectangles, and Rhombuses are the different types of quadrilaterals. Parallelograms also include squares, rectangles, and rhombi.

• All quadrilaterals have a few characteristics. Parallelograms characteristics are each of them has four vertices, each side has four sides, 360 degrees is the sum of all interior angles and two diagonals are present.

•There are regular and irregular quadrilaterals. An ordinary quadrilateral must have four equal sides, four equal angles, and diagonals that cross one another. Only the square can fulfill each of these requirements of a quadrilateral.

As we know that the opposite angles of a parallelogram are equal

hence 10x + 27 = 2x + 29

8x = 2

x = 0.25

Hence, the angles are 29.5

Let the value of angle v and x be a

Now using angle sum property of a parallelogram

29.5 +29.5 + a + a = 360

2a = 301

a = 150.5

The solution is j = 1.5.

Additional comment

You are often taught to solve this kind of 3-step equation by subtracting the unwanted variable term and the unwanted constant term in two steps. (The third step is dividing by the coefficient of the variable.) Here, we show those subtractions being done both at once.

The variable term we choose to subtract is the one with the smallest coefficient. That way, the result of the subtraction (1.8j) leaves the coefficient of the variable as a positive number.

Sometimes the variable term on the right is subtracted, so you end up with a "j = " equation. In that case, the equation you would be solving as the last step is ...

  -1.8j = -2.7

which requires arithmetic with negative numbers. Negative numbers tend to be associated with more mistakes, so we choose not to go there.

What is simplification?

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

here,
Total rent = $ 1475
The total area of the place =  12× 10 + 10×11.2 + 12 × 12.6 = 383.2 units

Now,
Rent per square units = 1475/ 383.2 = $3.8
Now,
rent of bedroom with measure 12 by 10 = 12 × 10 × 3.8 = $456
rent of bedroom with measure 10 by 11.2 = 10 × 11.2 × 3.8 =  $456
rent of bedroom with measure 12 by 12.6 = 12 × 12.6 × 3.8 = $574.56
