a photograph measures 10 inches by 12 inches. a frame with constant width is placed around the photograph so that the total area of the framed photo is 288 square inches. what is the width of the frame? enter your answer in the box.

Answers

The correct answer is 3 inches.

To find this answer, we need to write and solve a quadratic equation.

Let's call the width of the frame X.

Then, the total width is 10 + 2x and the total length is 12 + 2x.

Having this information, we can write and solve the following equation.

(10 + 2x)(12 + 2x) = 288
4x^2 + 44x + 120 = 288
4x^2 + 44x - 168 = 0
4(x - 3)(x + 14) = 0

The solutions are 3 and -14, but only 3 makes sense in the story problem.

Answer: EP is 12 and EO is about 10.91.

To find the length of EP, we can use the Pythagorean Theorem with the 2 legs of the right triangle it would form, EC and CP. CP would be 5 because it is the midpoint of the side.

5^2 + (EP)^2 = 13^2
EP = 12

Now, to find EO, we write and solve another Pythagorean Theorem equation using 12 for EP.

5^2 + (EO)^2 = 12^2
EO equals the square root of 119 or about 10.91.

Miguel wants to rent a boat and spend at most $52. The boat costs $7 per hour, and Miguel has a discount coupon for $4 off. What are the possible numbers of hours Miguel could rent the boat?
Use t for the number of hours- write your answer as an inequality solved for t. this is due today plz help thank you!

Answers

t ≤ 8

"At most" is equivalent to "less than or equal to". So the inequality is going to involve the less than or equal to symbol. The boat costs $7 per hour and that can be represented by:

7t

A discount coupon means subtracting $4 from the 7t:

7t - 4

When these are placed with the inequality:

7t - 4 ≤ 52

Solving this inequality means isolating the variable. To do this, adding 4 to both sides will be the first step.

7t ≤ 56

Finally, dividing both sides by 7 will get the final answer of 8, meaning the possible number of hours Miguel could rent the boat is no more than (less than or equal to) 8.

If there are 14 people sitting evenly spaced around a circle which person is directly across from the 2nd person?

Answers

Answer:

The 9th

Equation:

14/2=7 so 7 and 14 facing each other

Draw a circle with that

Draw 6 dots on each blank side

2 rom 14 is 2 so 7+2=9

So the answer is 9th

Final answer:

To determine which person is directly across from the 2nd person in a circle with 14 people, person 9 is directly across from the 2nd person.

Explanation:

To determine which person is directly across from the 2nd person in a circle with 14 people, we need to use modular arithmetic. If we number the people in the circle from 1 to 14, the person directly across from the 2nd person would be 9th. This can be found by adding 7 (the total number of people in the circle divided by 2) to 2, and then taking the remainder when divided by 14. Therefore, person 9 is directly across from the 2nd person.

Final answer:

To determine the percentage of a pie chart slice, divide the value by the whole and multiply by 100. The pie represents the entire data set, and the slices show the percentage that each category contributes to the whole.

Explanation:

To find out the percent of a pie chart, observe that each slice of the pie represents a specific share of the whole. If you know the entire value that the pie chart represents, you can calculate the percentage for each slice by dividing the value of the slice by the total value and multiplying by 100. For instance, if a pie chart represents the population by age groups, and there are 1000 people in total where 200 are aged 65 and over, the slice of the pie chart for those 65 and over would be (200/1000)*100, which equals to 20%.

Pie graphs are particularly useful for displaying how a whole is divided into parts, such as in division of government spending, categorization of the population, or distribution of market share among firms. A key point to remember is that the sum of all percentages in a pie chart should equal 100%, unless it is representing overlapping categories where participants can be counted in multiple categories. When that's the case, a pie chart is not the appropriate graph to use.

Calculate the MADs for the teachers' scores. Did the teachers make progress in standardizing the scores?

Answers

The teacher made progress in standardizing the test scores from the beginning of the year to the end. The MAD tells us this because the difference in the teachers scores from the mean is less at the end. The Mean Absolute Deviation is a measure of variability, and the smaller the number, the less variability there is in the answers. So, in this example there are more scores closer to the average than when they first graded the essays.

Step-by-step explanation:

Courtney has $4.95 in nickels, quarters, and dimes. She has12 quarters and 9 nickels. How many more dimes than nickels does she have?
A. 15
B. 10
C. 6
D. 4

Answers

The answer to this is C. 6

You have to find the value of the coins that you have now. Then you add them. Next, you subtract that value from the original total of 4.95. After that, you take that amount and divide it by the value of a dime. Lastly, you subtract the number of nickels from the number of dimes.
So 12x.25=3 and 9x.05=.45
3+.45=3.45
4.95-3.45=1.5
1/5/.10=15
15-9=6
The answer is 6.

Final answer:

Calculate the difference in the number of dimes and nickels to find out how many more dimes Courtney has. The solution involves determining the total value of quarters and nickels, finding the number of dimes, and subtracting to get the difference. There are 6 more dimes than nickels.

Explanation:

To find how many more dimes Courtney has than nickels:

Calculate the value of quarters: 12 quarters * $0.25 = $3.00

Calculate the value of nickels: 9 nickels * $0.05 = $0.45

Subtract the total value of quarters and nickels from the total amount: $4.95 - $3.00 - $0.45 = $1.50

Since each dime is $0.10, divide $1.50 by $0.10 to find the number of dimes Courtney has: $1.50 / $0.10 = 15 dimes

Calculate the difference between the number of dimes and nickels: 15 dimes - 9 nickels = 6 more dimes than nickels

Therefore, Courtney has 6 more dimes than nickels.

How many ways can a jury of four men and three women be selected from twelve men and ten women

Answers

There are 59,400 ways this jury can be selected.

Since the events are independent of each other (choosing one does not influence the chance of choosing the others) we multiply the combinations.

The first combination is [tex]_1_2C_4[/tex], because we are selecting 4 men from a possible 12.

The second combination is [tex]_1_0C_3[/tex], because we are selecting 3 women from a possible 10.

Multiplying these we have: [tex]_1_2C_4 \times _1_0C_3 \\ \\=\frac{12!}{4!8!} \times \frac{10!}{3!7!} \\ \\=\frac{479001600}{967680} \times \frac{3628800}{30240} \\ \\=495 \times 120 \\ = 59400[/tex]

Final answer:

The number of ways to choose the jury is 59,400.

Explanation:

The question is concerned with a combinatorial problem of selecting a jury from a larger pool of people, which is a classic example of the use of combinations in probability and statistics.

To find out how many ways we can select a jury of four men from twelve men, and three women from ten women, we use the combination formula which is C(n, k) = n! / (k! * (n-k)!), where '!' represents factorial, 'n' is the total number of people, and 'k' is the number of people to choose.

To select the men, we calculate the combinations as follows:

C(12, 4) = 12! / (4! * (12-4)!) = 495 ways

To select the women, we calculate the combinations as follows:

C(10, 3) = 10! / (3! * (10-3)!) = 120 ways

To find the total number of ways to select the jury of four men and three women, we multiply the number of ways to choose the men by the number of ways to choose the women:

495 ways (to choose men) * 120 ways (to choose women) = 59,400 different ways to select the jury.

Miguel has $20. He spends $6.25 on a movie ticket, $3.70 for snacks, and $1.25 for bus fare each way.

Answers

So we know Miguel has 20$ so from there we subtract the prices of the movies ticket, snacks, and the bus fares.
20 - 6.25 = 13.75

13.75 - 3.70 = 10.05

Since the bus fare is each way (to and back) we multiply 1.25 x 2
1.25 x 2 = 1.50

10.05 - 1.50 = 8.55
He has $8.55 left

Graph the linear equation find three points that solve the equation then plot on the graph x-3y=-6 plz help

Answers

Final answer:

The linear equation x - 3y = -6 can be rearranged as y = (1/3)x + 2. By substituting x-values of 0, 3, and 6, we obtained three points (0,2), (3,3), and (6,4). Plotting these points to graph helps us to visualize the equation.

Explanation:

The original linear equation is x - 3y = -6. We can rearrange this equation to y = (1/3)x + 2. From this, we can derive three points on the graph. For example, let's calculate the y-values for x = 0, 3, and 6, which are easy to use.

For x = 0, the equation becomes y = (1/3)(0) + 2 = 2. So, the point (0,2) lies on this line.

For x = 3, the equation becomes y = (1/3)(3) + 2 = 3. So, the point (3,3) is on the line. For x = 6, the y-value is y = (1/3)(6) + 2 = 4, giving us the point (6,4).

These three points can be plotted on a graph and a line can be drawn through them to graph the equation.
