This is the first year Janis is playing softball. She has been practicing her batting. On her last swing the bat made an arc with a radius of 48 inches and swept through 255° of rotation. Assuming the arc is circular, what is the distance the tip of the bat travels in inches in terms of pi? How many feet is this in terms of pi?
Answers
Using the relation between arc length and the radius, the arc length covered by the bat tip for a swing of 255 degrees with a 48-inch radius bat is (85/6)π inches or (85/72)π feet.
Explanation:The subject of the question is based in mathematics, specifically geometry. To solve the question, first, we have to know that the circumference (C) of a given circle is calculated as
2πr
, where 'r' is the radius. Since 255° is a portion of the total circumference (which is considered as 360°), we calculate the fraction of the total circumference covered by 255°, which is 255/360. The arc covered by Janis's bat swing is, therefore,
(255/360)*2πr
. Substituting 'r' with 48 inches, the arc length (As) comes to
(85/6)π inches
. To convert this to feet, divide the result by 12 (since there are 12 inches in one foot), which gives
(85/72)π feet
.

the stairs?
Answers
Answer:
it would be close to 12 ft im not 100% sure though the measurements are a little off
Step-by-step explanation:
hypotenuse is 13
then you have the adjacent = 7
13^2 = 169
7^2= 49
169-49=120
the square root of 121 is 11 wich is fairly close to 120(doesnt have one because its not exact)
there is two extra feet so 11 +2 is 13 but there was a little less then 11 so i had sid roughly around 12

The total height of the stairs can be found by adding the distance from the ground to the end of the slide (7 feet) and the extra height of the stairs (2 feet). This adds up to a total height of 9 feet for the stairs.
Explanation:The subject of the question is Mathematics, and it's suitable for a Middle School level. The problem can be solved using basic addition, and the concept of distance and height.
First, identify the length of the slide, which is 13 feet. Next, you're told that the end of the slide is 7 feet away from the stairs. This distance represents the height from the ground to the end of the slide. Lastly, you're told that the stairs extend 2 feet higher than the end of the slide.
Add these two distances together. So, the total height of the stairs is 7 feet (height to end of slide) plus 2 feet (additional height of stairs) equaling 9 feet.
So, the stairs are 9 feet tall.

Answers
To be a function, each input must correspond to exactly one output. In all cases except for Timon's gumballs, each distinct input yields a distinct output. Therefore, the sentence about Timon's gumballs does not represent a function.
Explanation:In mathematical terms, a function is a relation between a set of inputs and a set of permissible outputs with the property that each input is related to exactly one output. Let's go through these situations separately:
Notebooks are sold in a four pack for $20 and a five pack for $25. Here, the input, or the number of notebooks, determines the output, or price. No two outputs are the same for any given input. This is a function.Shaunette charges $20 for one hour of babysitting and $40 for two hours. The input (hours) determines the output (price). Similar to the first example, no two outputs are the same for any one input. This is a function.Marcy drove 50 miles in one hour today and 100 miles in two hours yesterday. The input (time) determines the output (distance traveled). There is a unique output for each input. This is a function.Timon chewed six gumballs in two hours today and six gumballs in three hours yesterday. This time, for different inputs (different hours), the output (number of gumballs chewed) is the same. This does not comply with the definition of a function because a function should have a unique output for each input.

Tickets to a spring concert are $5.00 for students and $8.00 for adults. 250 tickets to the concert were sold for a total of $1550. How many tickets adult tickets and how many student tickets were sold?
Answers
Answer:
100 adult tickets
150 students tickets
Step-by-step explanation:
First, construct an equation that relates the tickets.
For the first equation, 5x represents $5 per ticket for students and 8y represents $8 per ticket for adult, showing the money earned.
For the second equation, x represents student tickets and y represents adult tickets, showing the tickets sold.
[tex]5x+8y=1550\\x+y=250\\[/tex]
Then, you have to cancel out similar factors. I will multiply the second equation by -5 because that is the easiest option for this specific case.
[tex]-5(x+y=250)\\-5x-5y=-1250\\5x+8y=1550\\3y=300\\y=100[/tex]
We have solved for y, which is how many adult tickets were sold. To solve for student tickets, we will solve the second equation.
[tex]x+y=250\\x+100=250\\x=150[/tex]
As a result we have 100 adult tickets and 150 student tickets.

Answers
The volume of the rectangular pyramid with the given values of height and base area is 138.5 cubic inches.
What is a right triangular pyramid?A right triangular pyramid is simply a triangular pyramid which has an equilateral base, and whose top is directly above the base's centroid.
The volume of right triangular pyramid is expressed as;
V = 1/3 × b² × h
where b is the length of the base and h is the perpendicular height.
Given the data in the question;
Height of the pyramid h = 10in Base area A = 41.57in²First we find the dimension of the base length.
Since area square is A = b².
Hence;
41.57in² = b²
b = √41.57in²
b = 6.447in
Now, we substitute our values into the expression above.
V = 1/3 × b² × h
V = 1/3 × (6.447in)² × 10in
V = 1/3 × 41.563809in² × 10in
V = 138.5in³

Whats is x in that problem
Answers
Answer:
x=1/3
Step-by-step explanation:
You have to isolate the variable, so you must first separate the constants from the variable. Add 3 on both sides to cancel out the minus three and to move it to the other side. Now you have 27x=9. It's pretty simple from there just use your calculator and divide 27x/27 and also 9/27. That leaves you with 1/3
To solve for x in the equation 27x+3=6, we subtract 3 from both sides, divide both sides by 27, and get the solution x = 1/9.
Explanation:To solve for x in the equation 27x+3=6, we'll start by isolating the variable x. First, subtract 3 from both sides of the equation to get 27x = 3. Then, divide both sides by 27 to find the value of x.
Subtract 3 from both sides: 27x + 3 - 3 = 6 - 3Simplify: 27x = 3Divide both sides by 27: x = 3 / 27Simplify the fraction: x = 1/9Therefore, the solution to the equation is x = 1/9.
Juanita is booking a 4-night stay at a hotel. The rate is $79 per room plus tax.
If state tax is 6%, city tax is 2%, and municipal tax is 1%, what is her total
lodging cost?
Answers
if it’s $79 per night, then the answer is $344.44
if it’s $79 for all 4 nights, then the answer is $86.11
Final answer:
To determine the total lodging cost for Juanita's 4-night stay, multiply the nightly rate by the number of nights to get the pre-tax cost, calculate the total tax rate and apply it to the pre-tax cost to find the tax amount, and then add this tax to the pre-tax cost for the total cost. The total lodging cost, including taxes, will be $344.44.
Explanation:
Juanita is trying to calculate the total cost of a 4-night stay at a hotel with a nightly rate and additional taxes. To find Juanita's total lodging cost, a multi-step calculation is required. First, calculate the cost before tax by multiplying the nightly rate by the number of nights. Then, calculate the total tax by adding the state, city, and municipal tax rates and applying this sum to the pre-tax cost to get the total tax amount. Finally, add the tax amount to the pre-tax cost to find the total cost of the stay.
The nightly rate is $79 and she is staying for 4 nights, so the initial cost (before tax) is calculated as follows:
79 x 4 = $316
To calculate the total tax, convert the percentages to decimals and sum them up as follows:
State tax (6%) = 0.06
City tax (2%) = 0.02
Municipal tax (1%) = 0.01
Total tax rate = 0.06 + 0.02 + 0.01 = 0.09
Multiply the total tax rate by the pre-tax cost to find the total tax amount:
0.09 x 316 = $28.44
Finally, add the tax amount to the pre-tax cost to get the total lodging cost:
316 + 28.44 = $344.44
The total cost for Juanita's 4-night stay at the hotel, including all taxes, is $344.44.

Explanation:
The student's question involves the creation and interpretation of a box plot, which is a standardized way of displaying the distribution of data based on a five-number summary: minimum, first quartile (Q1), median, third quartile (Q3), and maximum. To graph a box-and-whisker plot for the given data values, one must first calculate the five-number summary:
Minimum (A): The smallest data value.First quartile (B): The median of the lower half of the data set. This marks the 25th percentile, meaning 25% of the data fall below this value.Median (C): The middle value of the dataset when ordered from least to greatest, which also splits the data into two halves.Third quartile (D): The median of the upper half of the data set. This marks the 75th percentile, so 75% of the data fall below this value.Maximum (E): The largest data value.Once these values are determined, one can create a box plot where the box represents the interquartile range (IQR), stretching from Q1 to Q3, with a line at the median (C). Whiskers extend from the box to the minimum (A) and maximum (E) values. Analyzing the box plot can give insights into the data set, such as the distribution of the data, any potential outliers, and the comparison of different data sets.

Ted and Katie have served up a total of $94 Tata saved six dollars less than four times as much is Katie how much has Katie saved
Answers
Answer:
Katie saved $20.
Step-by-step explanation:
I assume that "served" is a typo for "saved". Also, I assume that Tata and Ted are the same person.
Let the amount Katie saved = k
Then, ted saved $6 less than 4 times k, or 4k - 6.
The total saved by both is k + 4k - 6.
The total saved by both is $94.
k + 4k - 6 = 94
5k - 6 = 94
5k = 100
k = 20
Answer: Katie saved $20.
Final answer:
To determine the amount Katie has saved, two equations were set up based on the given information. The equations were solved simultaneously to find that Katie has saved $20.
Explanation:
Let's denote the amount Katie has saved as K and the amount Tata has saved as T. According to the problem, Tata saved six dollars less than four times as much as Katie, which we can write as T = 4K - 6. Additionally, we know that together they have saved a total of $94, so we can express this as K + T = 94. Substituting the expression for T from the first equation into the second equation, we get K + (4K - 6) = 94. Simplifying this, we get 5K - 6 = 94. By adding 6 to both sides, we obtain 5K = 100, and dividing by 5, we find that K = 20. Therefore, Katie has saved $20.
