Of the students in the marching band, 55%
plan to go to the school dance. If there are
110 students in the marching band that are
going to the dance, how many students
are in the marching band?

Answers

Answer 1

The answer is 200 because when you divide 110 from 55% you get 200.

Answer 2

Of the students in the marching band, 55% plan to go to the school dance, so there are 200 students in the marching band.

What is Percentage?

A certain portion or amount in every hundred is referred to as a percentage. The fraction is denoted by the sign "%," and its denominator is 100.

The Latin word "per centum," which means "by the hundred," is where the word "percentage" originally came from. With 100 as the denominator, percentages are fractions. To put it another way, it's the relationship between a component and a whole in which the value of the whole is always assumed to be 100.

From the given values in the question,

Assume that total number of students in marching band is x.

55% of x = 110 or,

(55/100) × x = 110

x = (110 × 100) / 55

x = 200.

Hence, it concludes that there are total 200 students are in the marching band.

The rectange's length is not known to us. N is it's variable

It says the width is 8 units mor then the length and ask for the are of the rectangle.

Now since rectangle's area is length times width we multiply n (the length) with the width (8+n).

Answers

Answer:

Average rate of change =250

Step-by-step explanation:

Formula to determine average rate of change of the function,

Average rate of change = [tex]\frac{f(x_2)-f(x_1)}{x_2-x_1}[/tex]

Where [tex]x_1[/tex] and [tex]x_2[/tex] are the points representing number of years after year 2000.

Since [tex]x_1[/tex] = 5 and [tex]x_2=19[/tex],

[tex]f(x_2)=650[/tex]

And [tex]f(x_1)=300[/tex]

Now average rate of change = [tex]\frac{650-300}{19-5}[/tex]

                                                = [tex]\frac{350}{14}[/tex]

                                                = 250

Therefore, average rate of change of the number of influenza cases from 2005 to 2019 is 250.

please help me with the domain and range of the graphs.?part 5​

Answers

Problem 5

Domain = [tex]-4 \le x \le 3[/tex]

This is because the smallest x value allowed is x = -4 as shown by the left-most point. The right most point has x coordinate x = 3, so this is the largest value in the domain.

The domain in interval notation is [-4, 3]. The square brackets include the endpoint.

--------------

Range = [tex]-4 \le y \le 5[/tex]

We're now looking at the possible y values. The lowest point happens when y = -4 and the highest point is when y = 5. We can have any y value between those endpoints.

The range in interval notation is [-4, 5]

=============================================================

Problem 6

Domain = [tex]-2 \le x < 2[/tex]

Same idea as the previous problem. This time the left most point has x = -2 and the right most point has x coordinate x = 2.

The big difference here is that the open hole says to not include the endpoint. The domain in interval notation is [-2, 2) where we use a parenthesis to not include the endpoint.

-------------

Range = [tex]-4 \le y < 4[/tex]

The smallest possible y value is y = -4. The ceiling for the y values is y = 4, but we can't actually reach this value due to the open hole.

The range in interval notation is [-4, 4)

=============================================================

Problem 7

Domain = [tex]-4 < x \le 2[/tex]

Same idea as earlier. Now the open hole is at the left endpoint. The right most point occurs not at an endpoint this time.

The domain in interval notation is (-4, 2]

-------------

Range: [tex]-4 < y < 4[/tex]

Both endpoints are open holes, so we exclude both endpoints.

The range in interval notation is (-4, 4). Unfortunately in this case, interval notation looks identical to ordered pair notation.

=============================================================

Problem 8

Domain = [tex]-5 < x < 3[/tex]

Domain in interval notation = (-5, 3)

the area of rectangle is 40 sq. cm. Find its length when it is 3 more than its width​

Answers

Answer:

8 cm.

Step-by-step explanation:

Area = length × width

Use the variable w instead of width.

Area = w × (w+3)

Substitute 40 for the Area

40 = w × (w + 3)

Create a table to find the greatest common factors of 40.

1 × 40, not it because 40 is 39 units greater than 1, not 3

2 ×20, not it because 20 is 18 units greater than 2, not 3

4 × 10, not it because 10 is 6 units greater than 4, not 3

5 × 8, correct because 8 is 3 units greater than 5

Now substitute 5 for w to check your answer

40 = 5 × (5 +3 )

40 = 5 × 8

40 = 40

The answer is correct.

A rectangle is a quadrilateral with 4 sides. In a rectangle, one side is longer than the other. The longer side is called the width and the shorter side is called the length.

The length of the rectangle is 8cm.

The formula  for the area of a rectangle is given as :

Length x Width

From the question, the length is 3 more than its width​. We can represent this mathematically as:

L = W + 3

Area of the rectangle = 40 sq. cm

Inputting this into the formula

(W + 3) x W = 40

W² + 3W = 40

W² + 3W - 40 = 0

Factorise

W² +8W - 5W - 40 = 0

W(W + 8) - 5(W + 8) = 0

(W + 8)(W - 5) = 0

To find W

W + 8 = 0

W = - 8 or

W - 5 = 0

W = 5 cm

Therefore, the width is 5cm.

To find the length, L = W + 3

L = 5 + 3

L = 8 cm

Therefore, the length is 8 cm.

Two people are pushing a car. One person is pushing with a force of 450 N and the
other person is pushing with a force of 300 N. What information is needed to
determine the net force applied to the car by the people?
the direction of the road
the direction of the forces
the weight of the two people
the weight of the automobile

Answers

Answer:

the direction of the road

Step-by-step explanation:

To calculate the net force, we need to know the direction through which the forces are acting.

Are the forces directed towards one another or against each other?

  Net force is a vector sum of forces that acts on a body. It is that single force that can replace two or more forces acting on a body.

If the forces are against each other, we subtract them. If they act on a body together, we add them.

So, without knowing the direction, we cannot calculate the net force.

The statement is either true in all cases or false. If false, construct a specific example to show that the statement is not always true. If v_1, ......, v_4 are in R^4 and v_3 = 2v_1 + v_2, then {v_1, v_2, v_3, v_4} is linearly dependent. Choose the correct choice below and, if necessary, fill in the answer boxes to complete your choice. a. True Because v_3 = 2v_1 +v_2, v_4 must be the zero vector. Thus, the set of vectors is linearly dependent. b. True. The vector v_3 is a linear combination of v_1 and v_2, so at least one of the vectors in the set is a linear combination of the others and set is linearly dependent. c. True. If c_1 =2, c_2 = 1, c_3 = 1, and c_4 = 0, then c_1v_1 + middot middot middot + c_4v_4 =0. The set of vectors is linearly dependent. d. False. If v_1 =, v_2 =, v_3 =, and v_4 = [1 2 1 2], then v_3 = 2v_1 + v_2 and {v_1, v_2, v_3, v_4} is linearly independent.

Answers

Answer: The correct option is (B).

True. The vector V₃ is a linear combination of V₁ and V₂, so at least one of the vectors in the set is a linear combination of the others and set is linearly dependent.  

Step-by-step explanation:  

Given that;

If V₁ ....... V₄ are in R⁴ and V₃ = 2V₁ + V₂ then {V₁, V₂, V₃, V₄} is linearly dependent.  

Lets {V₁, V₂, V₃, V₄}  are linearly dependent

Then there exist a scalars C₁, C₂, C₃, C₄

So that C₁V₁ + C₂V₂ + C₃V₃ + C₄V₄ = 0

where at least one of the Ci ≠ 0.  

Take C₃ ≠  0 then we have V₃ = (C₁V₁ + C₂V₂ + C₄V₄) / C₃

V₃ is a linear combination of V₁, V₂ and V₄}

that is

Given V₃ = 2V₁ + V₂

⇒ 2V₁ + V₂ - V₃ = 0

⇒ 2V₁ + V₂ + V₃ + 0V₃ = 0

Here, C₁ = 1, C₂ = 1,  C₃ = -1 and C₄ = 0

So that {V₁, V₂, V₃, V₄} is linearly dependent.

therefore option B id the right answer.

- True. The vector V₃ is a linear combination of V₁ and V₂, so at least one of the vectors in the set is a linear combination of the others and set is linearly dependent.  

B is the correct option. True, The vector V₃ is a linear combination of V₁ and V₂, so at least one of the vectors in the set is a linear combination of the others and the set is linearly dependent.  

If V₁ ....... V₄ are in R⁴ and V₃ = 2V₁ + V₂ then {V₁, V₂, V₃, V₄} is linearly dependent.  

What is meant by linearly dependent?

A set of vectors is linearly dependent if some vector can be expressed as a linear combination of the others.

Let's consider {V₁, V₂, V₃, V₄}  are linearly dependent

then there exist a scalars C₁, C₂, C₃, C₄

therefore, C₁V₁ + C₂V₂ + C₃V₃ + C₄V₄ = 0

where at least one of the Ci ≠ 0.  

Lets C₃ ≠  0 then we will get

V₃ = (C₁V₁ + C₂V₂ + C₄V₄) / C₃

V₃ is a linear combination of V₁, V₂, and V₄

which means V₃ = 2V₁ + V₂

2V₁ + V₂ - V₃ = 0

2V₁ + V₂ + V₃ + 0V₃ = 0

Here, C₁ = 1, C₂ = 1,  C₃ = -1 and C₄ = 0

therefore, {V₁, V₂, V₃, V₄} is linearly dependent.

So, option B is correct here.

True. The vector V₃ is a linear combination of V₁ and V₂, so at least one of the vectors in the set is a linear combination of the others, and the set is linearly dependent.

The management of Hartman Rent-A-Car has allocated $2.52 million to buy a fleet of new automobiles consisting of compact, intermediate-size, and full-size cars. Compacts cost $18,000 each, intermediate-size cars cost $27,000 each, and full-size cars cost $36,000 each. If Hartman purchases twice as many compacts as intermediate-size cars and the total number of cars to be purchased is 100, determine how many cars of each type will be purchased. (Assume that the entire budget will be used. Let x, y, and z denote the number of compact, intermediate-sized, and full-size cars purchased, respectively.)

Answers

Answer:

The number of compact cars = x = 30 cars

The number of intermediate-sized car = y = 60 cars

The number of full-size cars purchased = z = 10 cars

Step-by-step explanation:

Let us denote:

the number of compact car = x

the number of intermediate-sized car = y

the number of full-size cars purchased = z

The total number of cars to be purchased is 100.

Hence:

x + y + z = 100...........Equation 1

If Hartman purchases twice as many compacts as intermediate-size cars

y = 2x

So: x + 2x + z = 100..........Equation 2

= 3x + z = 100

z = 100 - 3x

Compacts cost $18,000 each, Intermediate-size cars cost $27,000

Full-size cars cost $36,000 each.

Assume that the entire budget will be used.

Hence,

x × $18,000 + y × $27,000 + z × $36,000 = $2,520,000.

18000x + 27000y + 36,000z = $2,520,000.....Equation 4

Substitute 100 - 3x for z and y = 2x in Equation 4

18000x + 27000(2x) + 36,000(100 - 3x) = $2520000

18000x + 54000x + 3,600,000 -108000x = $2520000

72000x -108000x + 3,600,000 = $2,520,000

= $3,600,000 - $2,520,000 = 108000x - 72,000x

$1,080,000 = 36,000x

Divide both sides by $36,000

x = $1080000/36000

x = 30

From the above:

y = 2x

y = 2 × 30

= 60

z = 100 - 3x

= 100 - 3 × 30

= 100 - 90

= 10

Therefore,

The number of compact cars = x = 30 cars

The number of intermediate-sized car = y = 60 cars

The number of full-size cars purchased = z = 10 cars
