Nathan and some friends are going to the movies. At the theater, they sell a bag of popcorn for $6 and a drink for $4. How much would it cost if they bought 5 bags of popcorn and 7 drinks? How much would it cost if they bought pp bags of popcorn and dd drinks?Total cost, 5 bags of popcorn, and 7 drinks: Total cost, p bags of popcorn and d drinks:

Answers

Answer 1

a) Since the cost of a bag of popcorn is $6 and the cost of a drink is $4,

[tex]\begin{gathered} T=6\cdot5+7\cdot4 \\ \Rightarrow T=30+28=58 \\ \Rightarrow T=58 \end{gathered}[/tex]

Therefore, the answer to the first question is $58.

b) Substitute 5 for p and 7 for d in the expression above; therefore,

[tex]T=6p+4d[/tex]

The total cost is given by the equation T=6p+4d, where T is in dollars, p is the number of bags of popcorn and d is the number of drinks.

Answers

The form of function that represents the bank account as a function of time is a linear function.

How to determine the type of function?

The table of values is given as illustrated:

Month Balance ($)

1           2,215.25

2          2,089.75

3           1,964.25

4            1,838.75

5            1,713.25

From the above table of values, we can see that the balance in the bank account reduces each month by $125.5

So, we have

Difference = 1,838.75 - 1713.25 =125.5

Difference = 1,964.25 - 1,838.75 =125.5

Difference = 2,089.75 - 1,964.25 =125.5

Difference = 2,215.25  - 2,089.75 =125.5

This shows a linear function.

During the spring, Mr. Salina's grass grows at a rate of 1.5 inches per week. During a rainy stretch in the summer, his grass grew a total of 8 inches in 4 weeks.

Answers

Based on the growth rate of Mr. Salina's grass per week in the summer, and in spring, the relationship is not proportional.

How are relationships proportional?

When relationships are said to be proportional, it means that they increase or decrease by the same rate.

In the spring, Mr. Salina's grass grows at a rate of 1.5 inches per week.

In the rainy stretch of summer, this rate goes to:

= Total number of inches / Number of weeks

= 8 / 4

= 2 inches per week

This means that the relationship is not proportional and one rate is higher than the other.

Answers

So, c(x) = 8.25x + 1500

the marginal cost doubles so, (8.25 x) will be 2 * (8.25x )

And the fixed cost decreased by 30%

so, 1500 will be (1 - 30%) of 1500

so, (1 - 30%) of 1500 = 70% of 1500 = 0.7 * 1500 = 1050

So, k(x) = 2 * (8.25x) + 1050

There are 3 consecutive even integers that sum to 186. What is the value of the greatest integer?

Answers

Answer:

The 3 consecutive even numbers are 60, 62 and 64 and the value of the greatest is 64.

Explanation:

If the numbers are consecutive even numbers, it means that the next number will be 2 more than the previous one.

Let the 1st number be x, then other 2 consective numbers will be x + 2 and x + 4.

We're told that the sum of the 3 consecutive even numbers is equal to 186, our equation can then be written as shown below;

[tex]x+(x+2)+(x+4)=186[/tex]

Let's go ahead and collect like terms and solve for x;

[tex]\begin{gathered} 3x+6=186 \\ 3x=186-6 \\ 3x=180 \\ x=\frac{180}{3} \\ \therefore x=60 \end{gathered}[/tex]

So our 1st number is 60.

Let's go ahead and find the other 2 numbers;

1st number: x + 2 = 60 + 2 = 62

2nd number: x + 4 = 60 + 4 = 64

So the 3 consecutive even numbers are 60, 62 and 64 and the value of the greatest is 64.

Sheldon is painting a wall in his house and is using a paint roller.The paint roller had a radius of 1 inch and a height of 8 inches.How many square inches of space Sheldon paint with one revolution of paint roller?Round to nearest tenths

Answers

The information we have about the paint roller:

Radius: r=1in

Height: h=8in

To find the answer to how many square inches of space he can paint with one revolution, it is useful to visualize the surface area of a cylinder:

The circles are the top and bottom of the cylinder, and the rectangle is the body of the cylinder (the paint roller). The area of this rectangle is the area that the paint roller will paint with one revolution.

Calculate the area of the rectangle:

To find the area, first, we need to find the length "L":

This length L is equal to the circumference of the circle defined as follows:

[tex]L=2\pi r[/tex]

So to find L we substitute r=1in and pi=3.1416:

[tex]\begin{gathered} L=2(3.14216)(1\text{ in)} \\ L=6.2832in \end{gathered}[/tex]

And finally, to find the area of the rectangle and thus, the area that the paint roller covers with one revolution, we multiply the length by the height:

[tex]A=h\times L[/tex]

Where "A" is area.

Substituting h and L:

[tex]\begin{gathered} A=8in\times6.2832in \\ A=50.2656in^2 \end{gathered}[/tex]

Rounding our answer to the nearest tenths:

[tex]50.2656\approx50.3[/tex]

The quadratic equation given is

[tex]\begin{gathered} 6p^2=8p+3 \\ 6p^2-8p-3=0 \\ \text{where a=6} \\ b=-8 \\ c=-3 \end{gathered}[/tex]

[tex]\begin{gathered} p=\frac{-(-8)\pm\sqrt[]{(-8)^2}-(4\times6\times-3)}{2\times6} \\ p=\frac{8\pm\sqrt[]{64+72}}{12} \\ p=\frac{8\pm\sqrt[]{136}}{12} \\ p=\frac{8\pm\sqrt[]{4\times34}}{12} \\ p=\frac{8\pm2\sqrt[]{34}}{12} \\ p=\frac{2(4\pm\sqrt[]{34)}}{12} \\ p=\frac{4\pm\sqrt[]{34}}{6} \\ p=\frac{4+\sqrt[]{34}}{6}\text{ or p=}\frac{4-\sqrt[]{34}}{6} \end{gathered}[/tex]

Therefore,

With the roots gotten from the quadratic equation, we can therefore deduce that the solutions to the equation 6p²=8p+3 will give 2 irrational roots.

In an art classroom, 8 students can sit around 1 table, and 48 students can sit around 6 tables. What is the relationship between the number of students to tables? (Do not reduce the ratios to their lowest terms.)

Answers

Answer: 8/1 = 6/48

Step-by-step explanation: um thats the answer bye

The relationship between the number of students to tables or the ratio of students to number of tables is 8 to 1.

According to question,

We have the following information:

In an art classroom, 8 students can sit around 1 table, and 48 students can sit around 6 tables.

Now, we will find the relationship between the number of students and the number of tables or in simple words, ratio.

So, we have:

8 students = 1 table

48 students = 6 tables

It can be rewritten by dividing both the sides by 6 as 8 students to 1 table.

It means that there are 8 students for 1 table.

Hence, the relationship between the number of students to the number of tables is 8 to 1.

Step 1

The equation of the second line is written in standard form. To know the slope of this line, we can rewrite its equation in slope-intercept form by solving for y.

[tex]\begin{gathered} ax+by=c\Rightarrow\text{ Standard form} \\ y=mx+b\Rightarrow\text{ Slope-intercept form} \\ \text{ Where m is the slope and b is the y-intercept} \end{gathered}[/tex]

Then, we have:

[tex]\begin{gathered} 4x-5y=-10 \\ \text{ Subtract 4x from both sides of the equation} \\ 4x-5y-4x=-10-4x \\ -5y=-10-4x \\ \text{Divide by -5 from both sides of the equation} \\ \frac{-5y}{-5}=\frac{-10-4x}{-5} \\ y=\frac{-10}{-5}-\frac{4x}{-5} \\ y=2+\frac{4}{5}x \\ \text{ Reorganize} \\ y=\frac{4}{5}x+2 \\ \text{ Then} \\ $$\boldsymbol{m=\frac{4}{5}}$$ \end{gathered}[/tex]

Now, two lines are perpendicular if their slopes satisfy the following equation:

[tex]\begin{gathered} m_1=-\frac{1}{m_2} \\ \text{ Where }m_1\text{ is the slope of the first equation and} \\ m_2\text{ is the slope of the second equation} \end{gathered}[/tex]

In this case, we have:

Since we already have a point on the line and its slope, then we can use the point-slope formula:

[tex]\begin{gathered} y-y_1=m(x-x_1)\Rightarrow\text{ Point-slope formula} \\ \text{ Where } \\ m\text{ is the slope and} \\ (x_1,y_1)\text{ is a point through which the line passes} \end{gathered}[/tex]

Then, we have:

In the first part of this problem, we must compute some statistic variables of two distributions:

0. the mean value,

,

1. the median,

,

2. the standard deviation.

,

3. the interquartile range.

1. The mean of a data set is the sum of all the data divided by the count n:

[tex]\mu=\frac{x_1+x_2+\cdots+x_n}{n}\text{.}[/tex]

2. The median is the data value separating the upper half of a data set from the lower half, it is computed following these steps:

• arrange data values from lowest to the highest value,

,

• the median is the data value in the middle of the set

,

• if there are 2 data values in the middle the median is the mean of those 2 values.

3. The standard deviation for a sample data set is given by the following formula:

[tex]\sigma=\sqrt[]{\frac{(x_1-\mu)^2+(_{}x_2-\mu)^2+\cdots+(x_n-\mu)^2}{n-1}_{}}\text{.}[/tex]

4. The interquartile range (IQR) is given by:

[tex]\text{IQR}=Q_3-Q_1\text{.}[/tex]

Where Q_1 and Q_3 are the first and third quartiles. The lowest quartile (Q1) covers the smallest quarter of values in your dataset.

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

Using the definitions above, we compute the mean, the median and the standard deviation for the samples taken by Manuel and Gretchen.

Manuel's sample

1. Mean

Using the formula above, we get:

2. Median

We order the data set:

[tex]3,3,5,6,6,7,8,(8),8,9,10,10,11,12,14.[/tex]

From the ordered data set, we see that the central number 8 divides the data set into two equal parts.

So the median of this sample is:

[tex]\bar{x}=8.[/tex]

3. Standard deviation

Using the formula above, we get:

[tex]\sigma=\sqrt[]{\frac{138}{15-1}}\cong3.14.[/tex]

4. Interquartile range

Dividing the data sample into quartiles, we have:

[tex]3,3,5,6|6,7,8|8|8,9,10|10,11,12,14.[/tex]

We have:

• Q_1 = 6,

,

• Q_3 = 10.

So the interquartile range is:

[tex]\text{IQR }=Q_3-Q_1=10-6=4.[/tex]

Gretchen's sample

• Sample = {22, 4, 7, 8, 12, 15, 10, 7, 9, 6, 13, 3, 8, 10, 10}

2. Median

We order the data set:

[tex]3,4,6,7,7,8,8,(9),10,10,10,12,13,15,22.[/tex]

From the ordered data set, we see that the central number 8 divides the data set into two equal parts.

So the median of this sample is:

[tex]\bar{x}=9.[/tex]

3. Standard deviation

[tex]\sigma=\sqrt[]{\frac{307.6}{15-1}}\cong4.69.[/tex]

4. Interquartile range

Dividing the data sample into quartiles, we have:

Equipment was purchased for $50,000. The equipment is expected to be used 15,000 hours over its useful life and has a residual value of $10,000. In the first two years of operation, the equipment was used for 2,700 hours and 3,300 hours, respectively. Using the activity-based method, what is the equipment’s accumulated depreciation at the end of the second year?

Answers

The equipment’s accumulated depreciation at the end of the second year is $16,000.

What is the accumulated depreciation?

Depreciation is the process used in expensing the cost of an asset. The activity based method allocates the depreciation expense using the number of hours the asset was used. Accumulated depreciation is the sum of the depreciation over a period of time.

Depreciation expense using the activity based method = (cost of the asset - residual value) x (number of hours used in a year / total number of hours)

Depreciation expense in year 1 = ($50,000 - $10,000) x (2,700 / 15,000)

$40,000 x 0.18 = $7,200

Depreciation expense in year 2 = ($50,000 - $10,000) x (3,300 / 15,000)

$40,000 x 0.22 = $8,800

Accumulated depreciation =  $8,800 + $7,200 = $16,000

One box of strawberries cost 5 dollars.

If one buys x boxes of strawberries, the cost would be (5x) dollars.

So, if one has 30 dollars, we want to find the maximum number of boxes that the person can buy, that is, the maximum value of x

5x ≤ 30

Divide both sides by 5

(5x/5) ≤ (30/5)

x ≤ 6

The number of boxes that one can buy is less than or equal to 6.

Hence, the maximum number of boxes that one can buy with 30 dollars is 6 boxes of strawberries.

Hope this Helps!!!

Assume your salary is $24,000 per year and $50 for each computer you sell. What function represents your total pay for one year? Be sure to indicate any domain restrictions.

Answers

Let x represent the total amount of computers you sell in one year.

Since you get $50 for each computer, then, you would get 50x for x computers.

Additionally, your base salary is $24,000. Then, add 50x and 24,000 to find your total salary in a year.

If f(x) is a function that represents your salary depending on the amount of computers you sell, then:

[tex]f(x)=50x+24000[/tex]

Notice that the amount of computers that you sell cannot be a negative number. Then, you must take into account the following restriction:

[tex]x\ge0[/tex]

Therefore, the answer is:

[tex]f(x)=50x+24000\text{ for }x\ge0[/tex]

solve by using quadratic formula25c^2 + 40c + 16= 0

Answers

Recall that the quadratic formula states that the solutions to the equation:

[tex]ax^2+bx+c=0[/tex]

are:

[tex]x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}.[/tex]

Therefore the solutions to the given equation are:

[tex]c=\frac{-40\pm\sqrt{40^2-4(25)(16)}}{2(25)}.[/tex]

Simplifying the above result we get:

[tex]c=\frac{-40\pm\sqrt{1600-1600}}{2(25)}=\frac{-40}{50}=-\frac{4}{5}[/tex]

Answer: The given equation has only one solution:

[tex]-\frac{4}{5}.[/tex]
