Match the following equation to the correct situation.
$6.50(c + 18) = $6.50c + $117.00
A. The amount of zoo admission for $6.50 more than c and $117.00.
B. The cost of a birthday package at the theater with a base cost of $117.00 plus $6.50 per child.
C. The amount for movie tickets for c adults when the cost is $6.50 more than $117.00 each.
D. The cost of attending a concert for c groups of people for $6.50 each.
Answer:
B
Step-by-step explanation:
You pay $117 no matter how many kids show up and then you pay an additional fee of 6.50 per kid.
1 kid
y = 6.50(1) + 117
y = 123.50
If 10 kids come
y = 6.50(10) + 117
y = 65 + 117
y = 182
You can use this equation to help you figure out how much it will cost you depending on how many kids you invite.
What is the slope of the line through (2,-2) and (9, 3)
Answer:it is 5/7
Step-by-step explanation: the formula for slope is rise/run divide and you get 5/7
Answer:
slope = \(\frac{5}{7}\)
Step-by-step explanation:
Calculate the slope m using the slope formula
m = \(\frac{y_{2}-y_{1} }{x_{2}-x_{1} }\)
with (x₁, y₁ ) = (2, - 2) and (x₂, y₂ ) = (9, 3)
m = \(\frac{3+2}{9-2}\) = \(\frac{5}{7}\)

Frabjous Day
Everyone at our lunch table was silent; our small world had been rocked to the core. Derrick, president of the computer chess club stared at his lunch tray as if it held some sort of threatening, inedible concoction from another planet. Laurel, the leader of my literary discussion group, was pale, looking as though she were coming down with some nasty illness. We had just learned that Frabjous Day, the best and only bookstore in our small town might have to close. Business was just too slow. (The charming name, of course, was from Lewis Carroll's nonsense poem "Jabberwocky.") People were purchasing books online or downloading them to their e-readers. No one seemed interested in a real bookstore anymore. This impacted us not only because our groups met at Frabjous Day, but also because we believed that the bookstore added value to life and the community.
"We need to save Frabjous Day, and we have to get all our classmates involved in the effort," Laurel said, breaking the painful silence. She was right, but the obstacles in our way made climbing Mt. Everest look like a walk in the park. We represented just a few people at our school, and we had no idea how to reach everyone.
"My brother is always quoting his basketball coach," Derrick said, "One word that keeps coming up is 'strategy.' Maybe that's what we need: a unique strategy to get everyone to recognize the value of Frabjous Day and become involved in the store."
I admired the idea immediately. Come to think of it, my literary group had recently read a classical book on strategy called The Book of Five Rings. It was written in the 1600s by a Japanese swordsman, and it describes the necessity of discipline, perception, and outthinking your opponent. I remembered a quote about there being more than one path to the mountaintop, which seemed appropriate.
After several days, we had developed a plan. First we talked with our principal and then with the owner of Frabjous Day. Finally, we set up a big display at school under the banner STRATEGIES FOR SUCCESS. We exhibited books like the Five Rings and a book written by a championship-winning basketball coach. We had a book of political writings by Gandhi and another on effective environmental conservation. I personally selected biographies of successful people, including a biography on a fabulously successful actress. We had a big sign that read: "Build strategies for succeeding at what you love! Visit Frabjous Day this afternoon after school. You'll learn a lot and enjoy free sandwiches and cookies." Laurel thought of that last part because, after all, food always brings people together.
Crowds of students turned up that afternoon. We knew we needed them to actively commit to saving the store. Derrick, a master at chess strategy, devised a personalized group approach for the athletes. He showed students how to play a computerized strategy game, explaining how to use the idea on a personal or athletic level. Under a sign reading "Have a blind date with a book," Laurel set up a display of books covered in brown paper, with a brief handwritten description of the contents that was purposefully vague, yet very enticing. I invited a TV personality who grew up in our town. Everyone wanted to meet a real celebrity! Even better, people got excited about helping each other and the bookstore.
Our local librarian, Mr. Chung, contributed the best idea of all. His college roommate had been the now famous guitarist and singer Joel J. Mr. Chung and Joel were also best friends with Cecily Armstrong, whose latest mystery novel was on the best-seller list. Mr. Chung printed out raffle tickets to be given with each book sold. At the end of the year, some lucky winner would have his or her name in an original Joel J song lyric. Another lucky winner would be a character in Ms. Armstrong's next novel. The raffle was a huge success. There was no doubt that Frabjous Day was going to have many frabjous days ahead.

The circumference of a circular park is approximately 18 feet. What is the approximate area inside the circular park?
Answer:
25.685 square feet.
Step-by-step explanation:
Circumference = 2 * π * radius
From this, we can derive the formula for the radius:
radius = Circumference / (2 * π)
Let's substitute the value of the circumference and calculate the approximate radius:
radius = 18 / (2 * π)
radius ≈ 18 / (2 * 3.14159)
radius ≈ 2.865 feet
Now that we have the approximate radius, we can calculate the area:
Area ≈ π * radius²
Area ≈ 3.14159 * (2.865)²
Area ≈ 3.14159 * 8.193225
Area ≈ 25.685 square feet
Therefore, the approximate area inside the circular park is approximately 25.685 square feet.
The classroom is 39 feet by 36 feet. What is the area of her classroom?
150 feet!
39x2 (39+39) = 78
36x2 (36+36) = 72
72 + 78 = 150
We have to double the set of numbers to find the area of the classroom. This is because there is 4 sides, and 2 are going to be different from the other two, and vise versa.
Mackey invested some money in an account paying 6% interest for one year. She invested $1000 more than this amount in an account paying 8.5%. How much did she invest in total if the total interest earned in the year was $737.50?
Step-by-step explanation:
Let's assume the amount Mackey initially invested in the 6% account is x dollars.
According to the given information, Mackey invested $1000 more than x in the 8.5% account, which means she invested (x + $1000) dollars in that account.
The total interest earned from the 6% account would be 0.06x dollars, and the total interest earned from the 8.5% account would be 0.085(x + $1000) dollars.
The total interest earned in the year is given as $737.50, so we can set up the equation:
0.06x + 0.085(x + $1000) = $737.50
Simplifying the equation:
0.06x + 0.085x + 0.085($1000) = $737.50
Combining like terms:
0.145x + $85 = $737.50
Subtracting $85 from both sides:
0.145x = $737.50 - $85
0.145x = $652.50
Dividing both sides by 0.145:
x = $652.50 / 0.145
x ≈ $4500
Therefore, Mackey initially invested approximately $4500 in the 6% account, and she invested $1000 more, which means she invested a total of $5500.
$4500
$4500
$4500
$4500

100 points and brainliest if answered quickly!!!! Nick is investigating cell phone use in his hometown. So far, he has found that the residents used their cell phones for 217,470 minutes last year. This year, they used their cell phones for a total of 434,940 minutes. What is the percent of increase in annual usage?
To calculate the percent increase in annual usage of cell phones, we can use the following formula:
Percent increase = [(new value - original value) / original value] x 100
where the new value is the current year’s usage and the original value is last year’s usage.
In this case, Nick found that residents used their cell phones for 217,470 minutes last year and 434,940 minutes this year. So we can plug these values into the formula:
Percent increase = [(434940 - 217470) / 217470] x 100
Percent increase = 100%
Therefore, there was a 100% increase in annual usage of cell phones.
I hope that helps! Let me know if you have any other questions.

In a pile of playing cards, there are six hearts, twelve clubs, and six diamonds. What is the probability that you will draw a heart?
1/2
1/6
1/4
1/3
Answer:
Step-by-step explanation:
1/4 because all equal 24 together
and so
12 is half so pulling a club would be 1/2
6 is a fourth so pulling a diamond or heart would be 1/4
because 6x2=12 so pulling a diamond or heart would be 50 - 50 from pulling a heart/diamond or a club
6=cards
2=diamonds and hearts
The probability of drawing a heart from the pile of 52 cards is 0.25.
The ratio of the number of favorable outcomes to the total number of outcomes of an event is defined as probability.
We know, the probability of an event = Number of favorable outcomes/Total number of outcomes.
As it is given that there are 6 hearts, 12 clubs, and 6 diamonds in a pile of playing cards.
Therefore, the total number of outcomes = 6+12+6= 24
and number of favorable outcomes = 6
Now, the probability of an event = 6/24
= 1/4
= 0.25
Therefore, the probability of drawing a heart is 0.25.

There are 2 red, 5 green, 3 blue, and 4 white points on a circle. Find the number of line segments which have vertices of different colors at the given points.
Answer:
Step-by-step explanation:
The number of those line segments which have endpoints of different colors is 47.
What is permutation and combination?
A permutation is the number of different ways a set can be organized; order matters in permutations, but not in combinations.
We have:
There are 5 red, 4 green, and 3 blue points on a circle.
There are different colored endpoints on each line segment that starts at a red point and travels to either a green point or a blue point.
There are 5 red points and 7 segments from each of them, making a total of 35 segments.
There are different colored endpoints on each line segment that leaves at a green point and travels to either a red or blue point.
There are 4 green points and 8 segments from each, for a total of 32 segments.
There are different colored endpoints on each line segment that leaves at a blue point and travels to either a green point or a red point.
Each blue point has 9 segments, and there are a total of 5 blue points.
Add all the ways = 35 + 32+ 27
= 94 segments.
Number of segment = 94/2 = 47
Thus, the number of those line segments which have endpoints of different colors is 47.

Reginald makes $8.00 per hour. Marie makes 15% less than Reginald. Sophie makes 20% more than Marie. How much does Sophie make per hour?
Answer:
R=$8 M=6.8 S=8.16
Step-by-step explanation:
First, you have to find 15% of 8. The answer is 1.2. Then we subtract 8-1.2. Next we get 6.8. That is how much money Marie makes per hour. So, we find 20% of 6.8. Which is 1.36. Then I add that to 6.8. The answer is 8.16. Hope this helps, let me know if correct, and have a great day!!
Calculate the area of the regular pentagon below:
Answer: 858.55 in
Step-by-step explanation: You calculate the area of the triangle ( 22.3 x 15.4/2), then you multiply the result by 5.
Answer:
858.55
Step-by-step explanation:
Area of triangle = 1/2BH
1/2(22.3*15.4) = 171.71
Because there is five sides on the pentagon we have to multiply the 172.71 by 5 to get the final answer.
171.1(5) = 858.55
Suppose Enrique has two building blocks. The area of one face of one of the blocks is 4 square centimeters and the area of the face of the other block is 100 square centimeters. What is the scale factor from the smaller block to the larger block?
Answer:
1:25
Step-by-step explanation:
Scale factor= 1:25
Answer:
The Scale factor is 5.
Step-by-step explanation:
Because the area has cm^2 to find the scale factor you find the number it takes to get from one area to the next and take the square root.
4X = 100
X = 100/4
X = 25 (Take the sqrt because of area)
X = sqrt(25)
X = 5
The Scale factor is 5.

3 questions. Write down the answer. Due in 2 days. 10 points. Answer must be correct/understandable!!
Answer:
1) F=25, G=65, and H=90 because similar triangles share similar angles but different sides, meaning the angles of triangle KJL are equivalent to the angles of triangle FGH.
2) Sides HG/LJ and FG/KJ equal to 2/1 as well because every side is multiplied by the same number to either enlarge or lessen the shape. Because of this, all ratios of original measures to altered ones will stay the same (2/1).
3) The correlating side of UV is RS and taking into consideration that the scale factor is 5/2, all we have to do is multiply 5/2 by 3.5ft , which gives us 8.75ft.
