Answer:

9.8 - 7.9n

Step-by-step explanation:

To simplify, we need to have the least amount of terms possible. To do this here, we need to group like terms. We will start by rearranging our equation to group our like terms, like this:

3.8 + 6 - 4.9n - 3n

Then, we will combine our liker terms, giving us:

9.8 - 7.9n

That is the most simplified we can get. So our simplified equation is

If you have two options, A and B, exclusive means only one option is required (A or B) while inclusive means both options are available (A and B).

To calculate the answer to this question, we need to consider what the words “exclusive” and “inclusive” mean. Exclusive means that one option is required and the other is not, while inclusive means that both options are available. In the case of the question a, the answer is exclusive because you must take either chemistry or physics to graduate. In the case of question b, the answer is inclusive because you can have either a complimentary coffee or tea.

To illustrate the difference between exclusive and inclusive with a formula, we can use the following:

Exclusive: A + B = A

Inclusive: A + B = A + B

This formula demonstrates that if you have two options, A and B, exclusive means only one option is required (A or B) while inclusive means both options are available (A and B).

The algebraic expression that shows the amount Ms. Jackson wants to rent a van for a week is T=320+0.50m

In order to calculate the total amount that Ms. Jackson will need to pay for renting we need to multiply the number of miles that she will drive by the price per mile driven.

Once we have that product we can simply add the weekly fee (w) to it which will give us the total (T) amount that Ms. Jackson will have to pay for her trip. This can all be combined into the following formula.

T = w + 0.50m

As per the mentioned table, a van containing ret for a week is 320, which is equal to the W value, then substitute the value in the equation we get:

= (2 + 2 + 2 + 2 + 2 + 2 + 2) + (5/8 + 5/8 + 5/8 + 5/8 + 5/8 + 5/8 + 5/8)

= 14 + (5/8 + 5/8 + 5/8 + 5/8 + 5/8 + 5/8 + 5/8)

Giovanna made an error when calculating the height of a stack of 7 books that are each 2 5/8 inches thick. The correct calculation was 14 7/8 inches, however, she calculated 14 + 5/8 inches. This is incorrect because it is necessary to add the fractions together in order to get the correct answer. To calculate the height of the stack of books, we need to add each book's thickness together. Since each book is 2 5/8 inches thick, we start by adding the whole numbers: 2 + 2 + 2 + 2 + 2 + 2 + 2 = 14. Then, we add the fractions: 5/8 + 5/8 + 5/8 + 5/8 + 5/8 + 5/8 + 5/8 = 7/8. Adding these together gives us 14 + 7/8 = 14 7/8. Thus, the correct answer is 14 7/8 inches.

What are arithmetic operations?

There are four fundamental operations that all real numbers in mathematics must comprehend:

1. Adding the numbers together to get their total (with a "+").

2. Using the "-" sign to subtract two numbers yields the difference between the values.

3. Multiplication('×') is used to create the numbers' product.

4. The division('÷') procedure, which determines the numbers' quotient.

We are given that Victoria bought a bag of mixed buttons and she got 12 large buttons and 138 small buttons.

So, the total number of buttons = 138 + 12 = 150

Out of 150, she got 12 large buttons.

The shaded region is made up of the area of a rectangle minus the areas of the semicircles. The semicircles have a diameter of 2 inches, so the radius of each semicircle is 1 inch.

The area of each semicircle can be found using the formula pir^2, where r is the radius. So the area of each semicircle is pi1^2 = pi square inches.

The area of the rectangle is found by multiplying the length by the width: 1 foot * 12 inches/feet = 12 square inches.

The shaded region is the area of the rectangle minus the area of the semicircles. So the area of the shaded region is 12 square inches - 2* pi square inches = 12 - 2* pi square inches.

A randomly selected subject has a 0.40 probability of completing more tasks than expected in 5 minutes while listening to relaxing music.

The Probability distribution is:

    X                     1                    2                3              4          

   P(x)             0.20          0.40      0.30             0.10

If listening to soothing music, the expected number of puzzles in 5 minutes can be calculated as follows:

            E(x) = ∑x p(x)

       ⇒ E(x) = 1 ×(0.20) + 2× 0.40 + 3 × 0.30 + 4× 0.1

       ⇒ E(x) = 0.20 + 0.8 + 0.9 + 0.4

       ⇒ E(x) = 2.3

Thus, a randomly selected subject could solve 5 puzzles while listening to soothing music. The probability of solving more tasks than expected in a minute is calculated as:

    P( X > 2.3) = P(X = 3) + P(X = 4)

                      = 0.30 + 0.10

Answer:

There are 6 workers in the team.

Step-by-step explanation:

Let's call the number of workers "n".

We know that the team of workers could have completed the job in 24 hours if they had worked together. We also know that the resulting work time would have been reduced by 6 hours if all but 5 workers had worked together from the start.

So, if n workers worked together from the start, the work time would be 24 - 6 = 18 hours.

We also know that the workers joined one by one, starting with 1 worker and ending with n workers working together.

The total work time can be calculated using the arithmetic series formula:

work time = n/2 * (1 + n)

So, if we set the work time to 18 hours:

18 = n/2 * (1 + n)

We can solve this equation for n:

18 = n/2 * (n+1)

36 = n^2 + n

n^2 + n - 36 = 0

We can solve this quadratic equation by factoring it.

(n-6)(n+6) = 0

So the solutions are n = 6 and n = -6.

But the number of workers can not be negative, so the answer is n=6.

The inequality that represents the numbers of large, and small, boxes that can be loaded in the trailer is 2x + y ≤ 60

A relationship between two expressions or values that are not equal to each other is called inequality.

Given that, One large box and two small boxes weigh a total of 100 pounds. One large box and four small boxes weigh a total of 150 pounds.

Let the weights of large and small boxes be x and y respectively.

x + 2y = 100

x = 100-2y...(i)

x + 4y = 150

x = 150-4y...(ii)

Solving eq(i) and eq(ii)

100 - 2y = 150 - 4y

2y = 50

y = 25

Put y = 25 in eq(i)

x = 100-50

x = 50

Therefore, weights of large and small boxes are 50 and 25 pounds respectively.

Now,

Since, weight limit of a trailer is 1500 pounds

Establishing the inequality,

50x + 25y ≤ 1500

or,

2x + y ≤ 60

Hence, the inequality that represents the numbers of large, and small, boxes that can be loaded in the trailer is 2x + y ≤ 60

Answer:

i) To find the maximum height of the projectile, we need to find the highest point that it reaches before falling back to the ground. In this case, the maximum height is the vertex of the parabola. To find the vertex, we can use the formula:

x=-b/2a

(12,845)

Substituting this value back into the original height equation, we find the maximum height:

h = -5(12)^2 + 120(12) + 125 = -300 + 1440 + 125 =845

So the maximum height of the projectile is 845 meters.

ii) To find when the projectile reaches its maximum height, we need to find the x-coordinate of the vertex of the parabola. As we found above, the x-coordinate of the vertex is 12 seconds. So the projectile reaches its maximum height at 12 seconds.

Triangle proportionality theorem and the segment addition postulate, indicates that A_F : AT = A_F : 4×A_F, therefore;

The location of the point D = AB, the location of the point B = AC

The point of intersection of the angle bisector of angle ∠A and DE = F

The point of intersection of the angle bisector of angle ∠A and BC = Point T

AD = 1, DB = 3, AE = 2, EC = 4

Drawing a line CU parallel to DE from point C to intersect AB at U, according to the triangle proportionality theorem, we get;

AE : EC = 2 : 4 = AD : DU = A_F : FV

AD : DU = 1 : 2

A_F : FV = 1 : 2

Therefore; FV = 2 × A_F

FV : VT = DU : BU = 2 : 1

FV = 2 × VT

2 × VT = 2 × A_F by substitution property, therefore;

FV = 2 × A_F

AT = A_F + FV + VT (segment addition postulate)
