The circle below represents one whole . …. What percent is represented by the shaded area ?

To find the tax we have to multiply the percent by the cost.

Remember that in order to do this we need to convert the 7% into a decimal, which means we need to divide it by 100.

7 / 100 = .07

Now lets multiply:

25 * .07 = 1.75

This means that our sales tax is A) $1.75.

I hope this helps! :)

Answer:

y² + y - 6

Step-by-step explanation:

(y - 2)(+ 1)(y + 3) simplifies to

(y - 2)(y + 3)

Each term in the second factor is multiplied by each term in the first factor, that is

y(y + 3) - 2(y + 3) ← distribute parenthesis

= y² + 3y - 2y - 6 ← collect like terms

= y² + y - 6

Answer:

vertex: (-5, 3)

Step-by-step explanation:

Besides providing the graph of the given quadratic equation, I will also demonstrate the algebraic method of solving for the vertex of a parabola.

Given the quadratic equation, y = -x² - 10x - 22, where:

a = -1, b = -10, and c = -22.

In order to find the vertex of the given equation, use the following formula to find the x-coordinate of the vertex: [tex]x = \frac{-b}{2a}[/tex].

[tex]x = \frac{-b}{2a}[/tex]

[tex]x = \frac{-(-10)}{2(-1)}[/tex]

[tex]x = \frac{10}{-2}[/tex]

x = -5

The x-coordinate of the vertex is: x = 5.

Next, substitute the value of the x-coordinate into the given quadratic equation to find its corresponding y-coordinate:

y = -x² - 10x - 22

y = -(-5)² - 10(-5) - 22

y = -25 + 50 - 22

y = 3

Therefore, the vertex of the given parabola is: (-5, 3), where it is the maximum point.  

One of the attachments is the screenshot of the graphed quadratic equation (using Desmos), where it shows  the vertex as the maximum point.

Answer:

X = 48 inches  for the shortest side

Step-by-step explanation:

9s = first side

10s = second side

4s = third side

Perimeter = sum of the sides

 276 = 9s + 10s + 4s

  276 = 23s

 276/23 = s

     12 = s

9s = first side;  9(12) = 108

10s = second side;  10(12) = 120

4s = third side; 4(12) = 48  

use the perimeter formula

P=2l+2w

P=2(3x+2)+2(x+4)

P=6x+4+2x+8

P=8x+12

Answer:

5

Step-by-step explanation:

22-2x ... (equation-1)

(x=-5)

Substituting the value of x in equation 1

22-2(x-5)

20(x-5)

20x-100

20x=100

x=100/20

x=5

Answer:

  a) see attached

  b) 41

  c) 56.2%

Step-by-step explanation:

a) We have drawn three circles, labeled D, C, B representing students who have dogs, cats, and birds, respectively. Based on the given information we can fill numbers in for all three animals (7), cats and dogs only (15), and birds only (8).

Then we can fill in cats and birds only by subtracting the number with all three. That will be 12 -7 = 5. Birds and dogs only is similarly filled by subtracting all three to get 20 -7 = 13 birds and dogs only.

Dogs only is found by subtracting the numbers in multiple categories from the total number of dogs: 90 -13 -7 -15 = 55. Cats only is found the same way: 68 -5 -7 -15 = 41.

The completed diagram is shown in the attachment. (We haven't figured the quantity for "none.")

__

b) 41 students have cats only

__

c) The total number with dogs only, cats only, or birds only is ...

  55 +41 +8 = 104

Of the 185 total students, that is 104/185 ≈ 56.2%.

56.2% of students have exactly one type of animal as a pet.

Answer:

2020

Step-by-step explanation:

if it is 5 consecutive numbers, it means it needs to be 2019, 2020, 2021, 2022, 2023

it is the number in the middle.

for the first 3 numbers, it is 2019, 2020, 2021

the middle number is 2020

The mean or average of the consecutive first 3 numbers such that the average of 5 consecutive whole numbers is 2021 will be 2020.

The mean is the average of a data set. Mean gives us an idea of that how much amount of overall data have.

In other words, the mean is the foundation of the deviation of data from all data sets.

Let's say the first integer is x.

Then, next terms will be x + 1, x + 2, x + 3, x + 4.

It is known that,

Mean = sum of data / Number of data

(x + x + 1 + x + 2 + x + 3 + x + 4)/5 = 2021

(5x + 10)/5 = 2021

x + 2 = 2021

x = 2019

Now, first, three consecutive integers will be,

2019,2020 and 2021

The mean of the above integers will be,

(2019 + 2020 + 2021)/3 = 2020

Hence "The mean or average of the consecutive first 3 numbers such that the average of 5 consecutive whole numbers is 2021 will be 2020".

Step-by-step explanation:

Angle C and angle with 120 degrees measure are alternate and their measurement is equal so C = 120

angle C and angle B are supplementary and so their sum is equal to 180

B = 180 - 120

B = 60

angle D and angle B are also alternate so their measure is also equal to each other therefore

Museums and galleries generally provide insight into human history. The lessons we may learn from historical occurrences, wonders, and tragedies are inestimably important, even though no museum claims to provide a complete picture. This is especially true when things are tumultuous.

In the interest of society, a museum investigates, gathers, conserves, interprets, and presents both tangible and intangible history. Through accessibility, inclusivity, and public accessibility, museums promote diversity and sustainability.
