i am working on the assumption that nobody does all three of them
i got 4 because including the people that do swimming and park, the total number of people that do swimming is 22.
the same logic goes for cycling: including the people that do swimming and visit the national park, the total is 23.
so that means that find how many people do swimming and cycling, we have to add the people doing only swimming, with the people doing both swimming and park and then subtract that answer from 22 which gives you 4

Jim is participating in a 6-day cross-country biking challenge. He biked for 59, 52, 66, 45, and 68 miles on the first five days. How many
miles does he need to bike on the last day so that his average (mean) is 59 miles per day?
miles
Answer:
Jim needs to bike 64 miles on the last day to maintain an average of 59 miles per day.
Step-by-step explanation:
To find out how many miles Jim needs to bike on the last day to maintain an average of 59 miles per day, we can use the concept of averages.
The total distance Jim needs to bike over the 6 days to maintain an average of 59 miles per day can be calculated as follows:
Total distance = Average distance per day × Number of days
Total distance = 59 miles/day × 6 days = 354 miles
Jim has already biked a total of 59 + 52 + 66 + 45 + 68 = 290 miles over the first five days.
To find out how many miles Jim needs to bike on the last day, we subtract the distance he has already biked from the total distance needed:
Distance needed on the last day = Total distance - Distance already biked
Distance needed on the last day = 354 miles - 290 miles = 64 miles
Therefore, Jim needs to bike 64 miles on the last day to maintain an average of 59 miles per day over the 6-day cross-country biking challenge.

There are 52 students taking none of the three languages.
There are 14 students taking both Arabic and Bulgarian. Of these, some may also take Chinese. We can find out how many by subtracting the students taking only Arabic or only Bulgarian from the total number of students taking Arabic and Bulgarian (14 + 15 + 19 = 48). So, 48 - 30 - 19 = 15 students are taking both Arabic and Bulgarian, and some of them may also take Chinese.
Next, we can subtract the students taking only Arabic, only Bulgarian, and only Chinese from the total number of students taking each language to find out how many students are taking all three languages.
From the students taking Arabic, we subtract the 15 students taking only Arabic: 30 - 15 = 15 students who may also be taking Bulgarian and Chinese.
From the students taking Bulgarian, we subtract the 19 students taking only Bulgarian: 36 - 19 = 17 students who may be taking Arabic and Chinese.
From the students taking Chinese, we subtract the 19 students taking only Chinese: 35 - 19 = 16 students who may be taking Arabic and Bulgarian.
So, there are 15 + 17 + 16 = 48 students who are taking some combination of the three languages.
Finally, to find out how many students are taking all three languages, we subtract the students taking only two of the languages from the total number of students taking some combination of the three languages (48 - (15 + 19 + 17) = 48 - 51 = -3). This means there are no students taking all three languages.
To find out how many students are taking none of the three languages, we subtract the total number of students taking some combination of the three languages from the total number of students at the school (100 - 48 = 52).
Hence, there are 52 students taking none of the three languages.

A) Two equations are,
S = 18 + 4t
L = 30 + 3t
Where, "t" represents the number of weeks that have passed.
B) It will take 12 weeks for Samuel and Lewis to have the same number of rocks in their collections.
C) when the amount of rocks in their collection is equal, Samuel and Lewis will have 66 rocks each.
Part A:
For a system of equations to represent the number of rocks in each person's collection.
Let "S" be the number of rocks in Samuel's collection and "L" be the number of rocks in Lewis's collection.
Hence, We can represent the situation as follows:
Equation 1:
S = 18 + 4t
Equation 2:
L = 30 + 3t
Where, "t" represents the number of weeks that have passed.
Part B:
To find out how many weeks it will take for Samuel and Lewis to have the same number of rocks in their collections, we need to set Equation 1 equal to Equation 2 and solve for "t".
This gives us the following:
S = L
18 + 4t = 30 + 3t
1t = 12
t = 12 weeks
Hence, It will take 12 weeks for Samuel and Lewis to have the same number of rocks in their collections.
Part C:
For number of rocks Samuel and Lewis will have when the amount of rocks in their collection is equal, we can substitute the value of "t" that we found in Part B into either Equation 1 or Equation 2.
Hence, substituting "t = 12" into Equation 1 gives,
S = 18 + 4(12)
S = 18 + 48
S = 66 rocks
Therefore, when the amount of rocks in their collection is equal, Samuel and Lewis will have 66 rocks each.

An online real estate website estimates that a fair price for Jerrold’s house would be $715,000. The market is
strong, so he is optimistic and puts the house on the market for $750,000. Two weeks later, the best offer
he’s gotten is $718,000, and so he accepts that offer. At what percent above the website’s estimate did he set
his asking price? At what percent below his asking price did he sell
Answer:
approximately 4.2667%
Step-by-step explanation:
To calculate the percentage above the website's estimate that Jerrold set his asking price, we can use the following formula:
Percentage above = ((Asking price - Website estimate) / Website estimate) * 100
Percentage above = (($750,000 - $715,000) / $715,000) * 100
Percentage above ≈ 4.895
Therefore, Jerrold set his asking price approximately 4.895% above the website's estimate.
To calculate the percentage below his asking price that Jerrold sold for, we can use the following formula:
Percentage below = ((Selling price - Asking price) / Asking price) * 100
Percentage below = (($718,000 - $750,000) / $750,000) * 100
Percentage below ≈ -4.2667
Therefore, Jerrold sold his house approximately 4.2667% below his asking price.

Is the relationship linear, exponential, or neither?
Based on the given data, the relationship appears to be exponential.
To determine if the relationship between the given values is linear, exponential, or neither, we can examine the pattern in the data.
If the relationship is linear, we would expect the values of y to increase or decrease at a constant rate as the values of x increase. In other words, there would be a constant slope between the points.
If the relationship is exponential, we would expect the values of y to change by a constant factor as the values of x increase. In this case, the relationship would exhibit exponential growth or decay.
Looking at the given values of x and y, we can observe the following differences between consecutive x-values: 7, 9, 9, 9. These differences are not constant, indicating that the relationship is not linear.
To determine if the relationship is exponential, we can examine the ratios between consecutive y-values: 5/10 = 0.5, 10/20 = 0.5, 20/40 = 0.5. These ratios are constant, suggesting that the relationship may be exponential with a common ratio of 0.5.

∠RQT is a straight angle. What are m∠RQS and m∠TQS?
Answer:
m∠RQS = 102°
m∠TQS = 78°
Step-by-step explanation:
A straight angle is equal to 180 degrees. We will create an equation to solve for x.
9x° + 3° + 7x° + 1° = 180°
16x° + 4° = 180°
16x° = 176°
x = 11
Next, we will substitute this value into the expressions representing the angles.
m∠RQS = 9x° + 3° = 9(11)° + 3° = 102°
m∠TQS = 7x° + 1° = 7(11)° + 1° = 78°
15x + 6 = 10x + 21
x = 3

through (-2, 1), perp to y=2x-5
Answer:
y = -1/2x
Step-by-step explanation:
Currently, y = 2x - 5 is in slope-intercept form, whose general equation is y = mx + b, where
(x , y) is any point on the line,m is the slope,and b is the y-intercept.The slopes of perpendicular lines are negative reciprocals of each other. We can show this with the following formula;
m2 = -1 / m1, where
m2 is the slope of the line we're trying to find, and m1 is the slope of the line we're given.Finding the slope of the other line:
Since 2 is the slope of y = 2x - 5, we can plug in 2 for m1 in perpendicular slope formula to find m2, the slope of the other line:
m2 = -1 / 2
m2 = -1/2
Thus, the slope of the other line is m = -1/2.
Finding the y-intercept of the other line:
We can find the y-intercept of the other line (i.e., b in the slope-intercept equation) by plugging in (-2, 1) for x and y and -1/2 for m in the slope-intercept form:
1 = -1/2(-2) + b
1 = 1 + b
0 = b
Thus, y = -1/2x is the line that passes through (-2, 1) and is perpendicular to y = 2x - 5.

Stephanie wanted to solve the equation 16=3x+1. Which inverse operations should she use to find the solution?
Subtraction and Division
Step-by-step explanation:Inverse operations help find the solution to equations.
Defining Inverse Operations
Firstly, let's define an operation. An operation in math is a function that can manipulate a value. Inverse operations are operations that are opposite operations that undo each other. For example, addition and subtraction are inverse operations because subtraction undoes addition. Multiplication and division are also inverse operations.
Solving the Equation
The equation 16 = 3x + 1 involves both addition and multiplication. So, to solve this, we can use the inverse operations of subtraction and division. First, subtract 1 from both sides.
15 = 3xThen, divide both sides by 3.
5 = xThis shows that by using subtraction and division, we can undo the addition and multiplication used in the equation. This allows us to find the value of x.

A rectangular tree lot must have a perimeter of 100 uards and an area of at least 500 square yards. Describe the possible lengths of the tree lot.
The possible lengths of the tree lot are 25 + 5√5 yards and 25 - 5√5 yards.
Let's denote the length of the rectangular tree lot as "l" and the width as "w".
We know that the perimeter of a rectangle is given by the formula:
Perimeter = 2(l + w)
Given that the perimeter of the tree lot must be 100 yards, we can write the equation as:
2(l + w) = 100
Next, we know that the area of a rectangle is given by the formula:
Area = l × w
Given that the area of the tree lot must be at least 500 square yards, we can write the inequality as:
l × w ≥ 500
Now, let's solve the equations simultaneously to find the possible lengths of the tree lot.
Perimeter equation:
2(l + w) = 100
l + w = 50
w = 50 - l
Area inequality:
l × w ≥ 500
Substituting the value of w from the perimeter equation into the area inequality, we have:
l × (50 - l) ≥ 500
50l - l^2 ≥ 500
l^2 - 50l + 500 ≥ 0
Now, we need to find the values of l that satisfy the inequality. Since the coefficient of the squared term is positive, the graph of this quadratic opens upward. This means that the values of l that satisfy the inequality will be either the entire range of possible values or a portion of it.
To find the possible lengths, we can either factor the quadratic or use the quadratic formula. Let's use the quadratic formula:
l = (-(-50) ± √((-50)^2 - 4(1)(500))) / (2(1))
l = (50 ± √(2500 - 2000)) / 2
l = (50 ± √500) / 2
l = (50 ± 10√5) / 2
l = 25 ± 5√5
Therefore, the possible lengths of the tree lot are 25 + 5√5 yards and 25 - 5√5 yards.
In summary, the possible lengths of the rectangular tree lot are 25 + 5√5 yards and 25 - 5√5 yards, respectively.

factor completely using distributive law -14-(-8)
Answer: To factor the expression -14 - (-8) completely using the distributive law, we need to simplify it first.
Remember that when we subtract a negative number, it is equivalent to adding the positive number. Therefore, -(-8) is the same as +8.
So the expression becomes:
-14 + 8
To factor it further using the distributive law, we can rewrite the addition as multiplication by distributing the -14 to both terms:
(-14) + (8) = -14 * 1 + (-14) * 8
This can be simplified as:
-14 + 8 = -14 * 1 + (-14) * 8 = -14 + (-112)
Finally, we can add the two negative numbers to get the result:
-14 + (-112) = -126
Therefore, the expression -14 - (-8) factors completely as -126.

Point A is translated 2 units up and 5 units to the right, where it now overlaps point B(3,-1)
Point A will have coordinates (-2, -3), which overlaps with the coordinates of Point B (3, -1).
To determine the new coordinates of Point A after the translation, we can start with the coordinates of Point B and apply the inverse translation.
Given that Point B has the coordinates (3, -1), we know that Point A after translation will have the same coordinates. We need to determine the inverse translation that will bring Point B back to its original position, and then apply that inverse translation to Point B.
The inverse translation of moving 2 units up and 5 units to the right is moving 2 units down and 5 units to the left. Therefore, we need to subtract 2 from the y-coordinate and subtract 5 from the x-coordinate of Point B.
Applying this inverse translation to Point B (3, -1), we have:
New x-coordinate of Point A = 3 - 5 = -2
New y-coordinate of Point A = -1 - 2 = -3

A water sample shows 0.052 grams of some trace element for every cubic centimeter of water. Robert uses a container in the shape of a right cylinder with a radius of 8.7 cm and a height of 17.3 cm to collect a second sample, filling the container all the way. Assuming the sample contains the same proportion of the trace element, approximately how much trace element has Robert collected? Round your answer to the nearest tenth.
To calculate the amount of trace element collected by Robert, we need to find the volume of the cylinder-shaped container. Rounded to the nearest tenth, Robert has collected approximately 211.4 grams of the trace element in the second sample.
To calculate the amount of trace element collected by Robert, we need to find the volume of the cylinder-shaped container and then multiply it by the concentration of the trace element.
The volume of a cylinder is given by the formula:
V = π * r^2 * h
where V is the volume, π is approximately 3.14159, r is the radius, and h is the height.
Given:
Radius (r) = 8.7 cm
Height (h) = 17.3 cm
Concentration of trace element = 0.052 grams/cm³
Substituting these values into the volume formula:
V = 3.14159 * (8.7 cm)^2 * 17.3 cm
V ≈ 4068.57196 cm³
Now, we can calculate the amount of trace element collected by multiplying the volume by the concentration:
Amount of trace element = V * concentration
Amount of trace element ≈ 4068.57196 cm³ * 0.052 grams/cm³
Amount of trace element ≈ 211.42941792 grams

This problem is relatively simple. Before we begin, it might be beneficial to imagine the graph as a vertical number line. Imagining it this way makes it easy to count the units between them and gives you the answer: [tex]$\boxed{4}$[/tex].
Here's a slightly more advanced way to think about it:
The example question tells us to subtract the distance between the two points. The formula for this is [tex]\sqrt{\big{(}(x_{2}-x_{1})+(y_{2}-y_{1})\big{)}^2[/tex], but for this question, let's say that it is [tex]\sqrt{(y_{2}-y_{1})^2[/tex], or, to simplify it even more, [tex]$|y_{2}-y_{1}|$[/tex]. Now that we know the formula, we can substitute our y-values into the last formula and solve. Let's say that Point C is our first point and Point D is our second.
[tex]\big{|}(-8)-(-4)\big{|} = \big{|}-8+4\big{|} = \big{|}-4\big{|} = \boxed{4}[/tex] , so [tex]$4\text{ units}$[/tex] is our answer.
Disclaimer: Neither of the last two formulas I provided is the actual formula, just a version of the Distance Formula that might be easier to understand. The first formula is the actual thing, but you will encounter this in math later in life, probably around 8th or 9th grade.
