The sun of two polynomials is -yz^2 - 3z^2 -4y + 4. If one of the polynomials is y - 4yz^2 - 3 ,what is the other polynomial?

Answer:

D

Step-by-step explanation:

Since the triangle is right use the sine trig ratio to solve for x

noting that sin45° = [tex]\frac{1}{\sqrt{2} }[/tex] ← exact value

sin45° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{8}{x}[/tex]

Multiply both sides by x

x × sin45° = 8 ( divide both sides by sin45° )

x = [tex]\frac{8}{sin45}[/tex] = [tex]\frac{8}{\frac{1}{\sqrt{2} } }[/tex] = 8[tex]\sqrt{2}[/tex]

Final Answer:

The population is the total number of students in the school.

Explanation:

The gym teacher's inquiry regarding the number of students playing a sport pertains to a subset of the larger student body. In statistical terms, the 20 students she questioned represent a sample.

The population, in this context, encapsulates the entirety of students attending the school, irrespective of whether they were asked about their sports participation or not.

When the gym teacher approached 20 students throughout the day, she was essentially drawing information from a limited group within the school. The population, however, extends beyond these 20 individuals to encompass every student enrolled in the institution.

This broader set includes students who might not have been present that day or were not approached by the teacher for their input. Determining the population aids in understanding the context and scale of the sampled data.

For instance, if the gym teacher's goal is to ascertain the percentage of students engaged in sports activities, the population figure (total number of students) becomes crucial for accurate statistical inference.

Consequently, the teacher can use this information to make informed decisions or implement strategies that cater to the entire student body, considering the interests and involvement in sports across the school.

Answer:

x=-1/2

Step-by-step explanation:

4x-6=10x-3

Subtract 4x from each side

4x-4x-6=10x-4x-3

-6 =6x-3

Add 3 to each side

-6+3 =6x-3+3

-3 = 6x

Divide each side by 6

-3/6 = 6x/6

-1/2 =x

➷ 4x - 6 = 10x - 3

Add 3 to both sides:

4x - 3 = 10x

Subtract 4x from both sides:

- 3 = 6x

Divide both sides by 6:

x = -1/2

The correct answer would be B. x = -1/2

Answer (a): Area of garden [tex]= 4x^2+12x+9[/tex]

Answer (b): Area of the square garden and the walkway =  [tex]16x^2+24x+9[/tex]

Step-by-step explanation:

Answer (a):

From given picture we see that Length of the garden = 2x+3

Width of the garden = 2x+3

Then area of the square garden = (Length)(Width)

[tex]= (2x+3)(2x+3)[/tex]

[tex]= 4x^2+6x+6x+9[/tex]

[tex]= 4x^2+12x+9[/tex]

Answer (b):

From given picture we see that width of the walkway = x

Then length of the garden including walkway =x + (2x+3) +x=4x+3

Similarly width of the garden = 4x+3

Then area of the square garden and the walkway = (Length)(Width)

[tex]= (4x+3)(4x+3)[/tex]

Answer:

m∠1 = (a + b) you will also need to divide the sum by 2

Step-by-step explanation:

The measures of angles formed by intersecting chord can be found by adding their arc measures and dividing in 2.

In this case, m< 1 = 1/2 ( a + b).

Based on the angle of intersecting chords theorem, the equation of that can be used to solve m∠1 is: m∠1 = 1/2(a + b).

The angle of intersecting chords theorem states that the measure of any of the vertical angles formed when two chords intersect equals half of the sum of the two intercepted arcs.

Therefore, based on the angle of intersecting chords theorem, the equation of that can be used to solve m∠1 is: m∠1 = 1/2(a + b).

Where,

Favorable outcomes are the occurrence of the event, for this case, it's equal to 1.

Outcomes are the possible occurrence of the event, for this case, it's equal to 3.

So, by substituting we have:

Step-by-step explanation:

Total Number of animals = 23 + 27 = 50

Number of Dogs = 27

Percentage of dogs = [tex]\frac{27}{50}[/tex] × 100 = 54%

The percentage of dogs will be 54%.

What is mean by Percentage?

A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.

Given that;

Number of cats = 23

Number of dogs = 27

Now,

Total number of animals = 23 + 27

                                      = 50

And, Number of dogs = 27

Hence, The percentage of dogs = (27/50) × 100

                                                  = 54%

Answer the anser is 3

please gimme brainly

Step-by-step explanation:

The length is 13 and width is 8

Let the length is L

Width will be L-5

Area of rectangle = Length x Width

Putting the values

104 = L x L-5

104=l(l−5)

Simplify both sides of the equation.

104=l²−5l

Subtract l²-5l from both sides.

104−(l²−5l)=l²−5l−(l²−5l)

−l²+5l+104=0

Factor left side of equation.

(−l−8)(l−13)=0

Set factors equal to 0.

−l−8=0 or l−13=0

l=−8 or l=13

We will take l = 13 because length cannot be negative

Now for width we know that w = l -5

So width is 13 -5 = 8

Answer:

208⅓ ft²

Step-by-step explanation:

The dimensions of Rachel's living room are 80 times the measurements on the scale drawing.

Calculate the width:

                                                                                     w = 80 × 1⅞

Convert the mixed number to an improper fraction     = 80 × 15/8

Cancel the 8s                                                                  = 10 × 15

                                                                                        = 150 in

Convert inches to feet                                                   = 150/12  

Convert the improper fraction to a mixed number      = (144 + 6)/12

                                                                                        = 12⁶/₁₂

Reduce the fraction to lowest terms                             = 12½ ft

Calculate the length

l = 80 × 2½  = 80 × 5/2 = 40 × 5 = 200 in = 200/12 = (192 + 8)/12

l = 16⁸/₁₂ = 16⅔ ft

Calculate the area

A = lw

A = 16⅔ × 12½

Convert the mixed numbers to improper fractions

A = 50/3× 25/2

Cancel the 2s

= 25/3 × 25

Multiply numerators and denominators                        

= 625/3

Convert the improper fraction to a mixed number    

= (624 + 1)/3

= 208⅓ ft²

The area of Rachel's living room is 208⅓ ft².

Answer:

1) The picture whose width = x and Length = (x + 8) feet

2) Width = 4 feet

   Length = 12 feet

Step-by-step explanation:

A rectangle has one side longer than the other.

Area of a rectangle = product of its sides.

                                  = length × width

Width = x feet

Length = (x + 8) feet

Area = 48

∴ x × (x + 8) = 48

   x² + 8x = 48

  x² + 8x + 4² = 48 + 4²

  (x + 4)² = 64

 x + 4 = √64

x = ±8 - 4

x = - 12        or x = 4

     Since length can not be negative, x = 4

∴ Width = 4 feet

   Length =4 + 8 = 12 feet

The dimensions of the rectangle where its area is 48 square feet and length is 8 feet more than width is 4 feet (width) and 12 feet (length). The question is set on algebra, calculation of area and understanding of shapes.

This problem falls under the category of algebra and involves understanding the concept of shapes, particularly rectangles, and calculation of their area.

We know, the area of a rectangle is calculated as the product of its length and width. Given that the area is 48 square feet and the length is 8 feet more than the width. Let's denote the width as 'w' and the length as 'w + 8'.

So, we can set up the equation as: w * (w + 8) = 48. Solving this quadratic equation will give us the values for 'w' and 'w + 8' or the dimensions of the rectangle.

If you factor the quadratic equation, you get (w - 4)(w + 12) = 0. Setting these factors to zero, we find that w = 4 or w = -12. Since width cannot be negative, the width is 4 feet. And the length, which is 8 feet more than the width, will be 4 + 8 = 12 feet.

For the picture representation, simply imagine or draw a rectangle. Label the shorter side as 4 feet (width) and longer side (length) as 12 feet.
