Answer:

The ratio of the number of dogs to the total number of dogs and cats in the veterinarian's office is 9:16.

Step-by-step explanation:

Ratio:

The ratio of a to b is given by:

[tex]a:b = \frac{a}{b}[/tex]

The ratio of dogs to cats in a veterinarian's office is 9:7.

This means that for each 9 dogs, there are 7 cars.

What is the ratio of the number of dogs to the total number of dogs and cats in the veterinarian's office?

9 dogs

9 + 7 = 16 dogs and cats. So

The ratio of the number of dogs to the total number of dogs and cats in the veterinarian's office is 9:16.

Answer:

Rounded to the nearest integer, the company has a total of 82,958 employees.

Step-by-step explanation:

Given that an international company has 25,800 employees in one country, if this represents 31.1% of the companies employees, to determine how many employees does it have in total, the following calculation must be performed:

31.1 = 25,800

100 = X

100 x 25,800 / 31.1 = X

2,580,000 / 31.1 = X

82,958.1 = X

Thus, rounded to the nearest integer, the company has a total of 82,958 employees.

Answer: 10

Step-by-step explanation: (5/6) times 12

Answer:

10

Step-by-step explanation:

[tex]\frac{5}{6}[/tex] × [tex]\frac{12}{1}[/tex]

Multiply 12 times 5 to get 60. Then, multiply 6 times 1 to get 6.

Lastly, divide 60 by 6, which equals 10.

Answer:

1.243 cm

Step-by-step explanation:

The surface area of a cylinder is the sum of the area of the two congruent circular bases and the rectangular lateral area.

[tex] SA = 2\pi r^2 + 2 \pi rh [/tex]

[tex] SA = 2\pi r(r + h) [/tex]

We are given the surface area and the diameter.

r = d/2 = 7 cm / 2 = 3.5 cm

We can solve for h, the height.

[tex] SA = 2\pi r(r + h) [/tex]

[tex] 2\pi r(r + h) = SA [/tex]

[tex] r + h = \dfrac{SA}{2\pi r} [/tex]

[tex] h = \dfrac{SA}{2\pi r} - r [/tex]

[tex] h = \dfrac{104.3~cm^2}{2(3.14159)(3.5~cm)} - 3.5~cm [/tex]

[tex] h = 1.243~cm [/tex]

Answer: (3.65, 3.74)

Step-by-step explanation:

Now, when we round a number to a given decimal place, we need to look at the decimal to the left of the decimal place where we are rounding.

if it is 5 or more, we round up

if it is smaller than 5, we round down.

Then for example, if we want to round:

4.534

to the first decimal place, we need to look at the second decimal place.

we can see that it is a 2.

Then we round down, and get:

4.5

Now we know that, when rounding to the first decimal place, we have:

x = 3.7

Then the maximum value that x could have is:

x = 3.74 (because here we round down to 3.7)

and the minimum value that x could have is:

x = 3.65 (because here we round up to 3.7)

Then the error interval for x is:

(3.65, 3.74)

Answer:

115

Step-by-step explanation:

To find the missing angle all you have to do is add the 2 nonadjacent interior angles which are 75 and 40 to get the exterior angle which is 115.

Answer:

8

Step-by-step explanation:

So first do 104+76+104=284

Now form the equation 10x-4+284=360

It is 360 because this is a quadrilateral.

Now combine like terms.

10x+280=360

10x=80

x=8

Check 80-4=76

The other angle is 76 so you know your answer is correct

Step-by-step explanation:

8x+17 = 30 + 5x +20

3x = 30 + 20 -17

3x = 30 + 3

3x = 33

x = 33/3

x = 11

measures = angle Q= 5x +20 = 5(11)+ 20 = 55+20 = 75

hope this will be helpful to you.

Number of green marbles in the bag is equals to [tex]56.[/tex]

" Number is defined as the count of any given quantity as per condition."

According to the question,

Given,

Total number of marbles [tex]= 84[/tex]

[tex]'x'[/tex] represents the number of red marbles

As per given condition,

[tex]'2x'[/tex] represents the number of green marbles

Required equation we have,

[tex]x + 2x = 84\\\\\implies 3x =84\\\\\implies x = \frac{84}{3} \\\\\implies x = 28[/tex]

Substitute the value of [tex]'x'[/tex] to get number of green marbles ,

Number of green marbles [tex]2x = 2\times 28[/tex]

                                                 [tex]= 56[/tex]

Hence, number of green marbles in the bag is equals to [tex]56.[/tex]

Check the attachment(s) for the graphs pertaining to the question

No. 1) Check graph [first attachment]

No. 2) y = (x - 2)^2 - 3, y = 1

           (x - 2)^2 - 3 = 1,

           (x - 2)^2 = 4

            x - 2 = √4, x - 2 = - √4

            x = 4, x = 0

Substitute back to determine the respectively y-value:

y = (4 - 2)^2 - 3 = (2)^2 - 3 = 4 - 3 = 1

Check: y = (0 - 2)^2 - 3 = (-2)^2 - 3 = 4 - 3 = 1

So the points of intersection are (4, 1) and (0, 1). According to the graph, that is correct.

Answer:

Elena's sales and expenses will both be $

396

if she sells

36

boxes of cards.

Step-by-step explanation:

The number of greeting cards are 36 and Elena's sales and expenses will both be $396.

Elena  paid $54 for a booth at the fair, and the materials for each box of cards cost $9.50.

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

Let the number of cards be x.

At some point, she will sell enough cards so that her sales cover her expenses.

So, 54+9.50x=11x

⇒ 11x-9.50x=54

⇒ 1.50x=54

⇒ x=54/1.50

⇒ x=36

Thus, sales=expenses= 11x

= 11×36

= $396

Hence, the number of greeting cards are 36 and Elena's sales and expenses will both be $396.
