The relationship between the total number of laps a swimmer swims (l) and the number of days (d) can be represented by the equation l = 12d. This equation is a linear equation.
In this equation, the number of laps (l) is directly proportional to the number of days (d) the swimmer swims. This means that for every day the swimmer swims, the total number of laps increases by 12.
To better understand this relationship, let's consider an example. Let's say the swimmer swims for 3 days. Plugging in d = 3 into the equation, we have l = 12 * 3 = 36. Therefore, the swimmer would have swum a total of 36 laps over the course of those 3 days.
Similarly, if the swimmer swims for 5 days, plugging in d = 5 into the equation gives us l = 12 * 5 = 60. So, the swimmer would have swum a total of 60 laps over the 5-day period.
The linear equation l = 12d represents a constant rate of increase, where the number of laps increases by 12 for each additional day of swimming.
In summary, the relationship between the total number of laps (l) a swimmer swims and the number of days (d) can be described by the equation l = 12d. This equation shows a direct proportionality between the two variables and represents a linear relationship.

I need an answer and explanation so I can try to do some myself thanks!:)
Answer:
B. -5
Step-by-step explanation:
this is quite simple, so what you are going to want to do is multiply -3 by 4, and -16, so distribute that and you'll end up with
-12x+48= -12
then you want to subtract 48 from both side to leave the x on one side alone
that will be -12x= -60
after that you have to divide both sides by -12 to find your x
so then you will see that your x is = -5! hope this helps!!

Step-by-step explanation:
The formula for calculating the sum of interior angles is:
(n - 2) x 180° (where n is the number of sides)
interior angle of a polygon = sum of interior angles ÷ number of sides
165 = [ (n - 2) x 180° ] ÷ n
Mulitply both sides by n: 165n = (n - 2) x 180°
Expand brackets: 165n = 180n - 360
Add 360 to both sides: 165n + 360 = 180n
Subtract 165n from both sides: 360 = 15n
Divide both sides by 15: 24 = n
Therefore, the number of sides = 24
5) Build mathematical model of the transportation problem: Entry elements of table are costs. Destination B2 B3 B4 28 A1 27 27 32 A2 15 21 20 A3 16 22 18 b 26 8 Source 3 BI 14 10 21 323324 12 13
This problem is an example of a balanced transportation problem since the total supply of goods is equal to the total demand.
The transportation problem is a well-known linear programming problem in which commodities are shipped from sources to destinations at the minimum possible cost. The initial step in formulating a mathematical model for the transportation problem is to identify the sources, destinations, and the quantities transported.
The objective of the transportation problem is to minimize the total cost of transporting the goods. The mathematical model of the transportation problem is:
Let there be m sources (i = 1, 2, …, m) and n destinations (j = 1, 2, …, n). Let xij be the amount of goods transported from the i-th source to the j-th destination. cij represents the cost of transporting the goods from the i-th source to the j-th destination.
The transportation problem can then be formulated as follows:
Minimize Z = ∑∑cijxij
Subject to the constraints:
∑xij = si, i = 1, 2, …, m
∑xij = dj, j = 1, 2, …, n
xij ≥ 0
where si and dj are the supply and demand of goods at the i-th source and the j-th destination respectively.
Using the given table, we can formulate the transportation problem as follows:
Let A1, A2, and A3 be the sources, and B2, B3, and B4 be the destinations. Let xij be the amount of goods transported from the i-th source to the j-th destination. cij represents the cost of transporting the goods from the i-th source to the j-th destination.
Minimize Z = 27x11 + 27x12 + 32x13 + 15x21 + 21x22 + 20x23 + 16x31 + 22x32 + 18x33
Subject to the constraints:
x11 + x12 + x13 = 3
x21 + x22 + x23 = 14
x31 + x32 + x33 = 10
x11 + x21 + x31 = 21
x12 + x22 + x32 = 32
x13 + x23 + x33 = 26
xij ≥ 0
In this way, we can construct a mathematical model of the transportation problem using the given table. The model can be solved using the simplex method to obtain the optimal solution.

Answer:
The volume of Cone B is twice the volume of Cone A.
Step-by-step explanation:
The volume of a cone is given by
V = 1/3 pi r^2 h where r is the radius and h is the height.
Cone A
d = diameter
r = radius
h = height
V = 1/3 pi r^2 h
Cone B
The diameter is double the diameter of A.
2d so the radius is 2r
The height is half the height of A.
1/2 h
Substitute into the equation for volume.
V = 1/3 pi ( 2r)^2 (1/2 h)
V = 1/3 pi (4r^2) (1/2h)
V = 1/3 pi 2r^2 h
The volume of Cone B is twice the volume of Cone A.
Answer:
Cone B has a greater volume.
Step-by-step explanation:
Cone B has the greatest volume.
The volume of a cone is calculated using the following formula:
\(\boxed{\bold{\tt{Volume\: of\:cone = \frac{1}{3}\pi*r^2h}}}\)
where:
π is a mathematical constant approximately equal to 3.14 r is the radius of the coneh is the height of the coneFor Cone A.
\(\boxed{\bold{\tt{Volume\: of\:cone\: (A)= \frac{1}{3}\pi*r^2h}}}\)
For Cone B
In this case, the radius of Cone B is double the radius of Cone A, and the height of Cone B is half the height of Cone A. This means:
radius(r)=2r
height(h)= \(\tt{\frac{1}{2}*\frac{h}{2}}\)
\(\boxed{\bold{\tt{Volume\: of\:cone\: (B)= \frac{1}{3}\pi*(2r)^2*\frac{h}{2}}}}\)
\(\boxed{\bold{\tt{Volume \: of\:cone (B)= 2*\frac{1}{3}\pi*r^2h}}}\)
\(\boxed{\bold{\tt{Volume(B) =2*Volume\: of\:cone(A)}}}\)
Since the volume of cone B is twice the volume of Cone A.
Therefore, Cone B has a greater volume.
A hiker keeps track of all the animal species she observes while on a hike. Of all the species she observes, 60% are insects. The hiker saw at least 12 different species of insects. Write an inequality that represents the total number of species, s, the hiker observed.
The inequality that represents the total number of species, s, the hiker observed, is s ≥ 20
How to find the inequality ?To represent the entirety of species seen by the hiker, we formulate an inequality as 60% of them were insects and she sighted not less than a dozen insect species.
Denoting "i" as the quantity of insect species, we translate conditions that the hiker witnessed at minimum twelve distinct types of bugs dissimilar from other species. Consequently, this yields:
i ≥ 12
We know that i = 0.6s. So we have:

Chase caught 2/3 of the balls hit to left field. Ryan caught 3/5 of the balls hit to right field. Which pair of equivalent fractions will help them find the total amount of the balls they both caught?
Answer:
1 4/15 balls
Step-by-step explanation:
From the question, we are told that:
Chase caught 2/3 of the balls hit to left field.
Ryan caught 3/5 of the balls hit to right field.
The Lowest common denominator for both fraction is given as 15
Hence, the equivalent fractions for each boy is calculated such that the denominators of both fraction is 15
For Chase:
We Multiply both numerator and Denominator by 5
2 × 5 /3 × 5 = 10/15
2/5 = 10/15
For Ryan
We Multiply both numerator and Denominator by 3
3 × 3 /5 × 3 = 9/15
3/5 = 9/15
The total amount of the balls they both caught is:
10/15 + 9/15
= 19/15 = 1 4/15
A. Iodine-131 has a half-life of 8.04 days. After how many days will only 12.5% of a given sample remain? Please answer in days.
B. What percentage of a tritium sample will remain after 11 years? The half-life of tritium is 12.3 years.
C. Modern paper has a disintegration rate of 15.3 counts per minute (A0) and carbon-14 has a half-life of 5730 years. You test the map with your pocket Geiger counter and measure 15.1 cpm.
Assuming that the C-14 in the paper has decayed, calculate the age of the paper that the map is written on. Please answer in years.
A. 24.12 days
B. 18.1%
C. 29868 years
A. How to find exponential decay of Iodine-131?Using the formula for exponential decay:
N(t) = N0 * (1/2)^(t/T)
We can rearrange this equation to solve for t:
t = T * log(0.125) / log(0.5)
simplifying, we get:
t = 8.04 * log(0.125) / log(0.5) ≈ 24.12 days
Therefore, it takes about 24.12 days for only 12.5% of the sample to remain.
B. How to find percentage decay of tritium?Using the same formula for exponential decay
N(11) = N0 * (1/2)^(11/12.3)
Dividing N(11) by N0 and multiplying by 100 gives us the percentage remaining:
N(11)/N0 * 100 = (1/2)^(11/12.3) * 100 ≈ 18.1%
Therefore, about 18.1% of the tritium sample will remain after 11 years.
C. How to find decay rate of carbon-14 ?The rate of decay of C-14 is given by:
A(t) = A0 * (1/2)^(t/T)
t = T * log(A(t)/A0) / log(0.5)
Plugging in the values for A(t), A0, and T, we get:
t = 5730 * log(15.1/15.3) / log(0.5) ≈ 29868 years
Therefore, the age of the paper that the map is written on is about 29868 years.

Answer: 5 inches
Step-by-step explanation:
Perpendicular bisectors must be split directly in half, as they are *bi*sectors, meaning "*two* sections"
Perpendicular means when two angles come together to create a 90° angle
This means that angle BDA is also a 90 degree angle
Since line AC is the line segment split by the perpendicular line segment BD, then you can assume that it is the only 8 inch line, according to multiple laws of geometry. This indicates that segment BC and segment BA must be congruent.

Your current portfolio has a Tracking Error Volatility of 3.5%. If the standard deviation of the market is 20% and the residual standard deviation of your portfolio is 1.5%, what is (are) the possible value(s) for Beta? σ TE2=(1−β) 2 σ m2 +σ ε2
The value of beta considering the standard deviation of the market is equal to 0.8419 or 1.1581
Tracking Error Volatility is defined as the standard deviation of the difference in returns between an investment and its benchmark.The extent to which the returns on a portfolio deviate from those of a benchmark is known as tracking error. It's also known as the active risk of a portfolio.It's typically expressed as a percentage and is computed as the standard deviation of the portfolio's active returns divided by the expected portfolio return or average benchmark return.
Beta (β) is a measure of a security or portfolio's volatility in comparison to the entire market. Beta compares the volatility of a security to that of the overall market, which has a beta of 1.0.The market, typically represented by an index such as the S&P 500, has a beta of 1.0. A beta of less than 1.0 indicates that the security is less volatile than the market, whereas a beta of more than 1.0 indicates that the security is more volatile than the market.As a result, beta is a measure of the systematic risk of a security or portfolio.
To calculate the possible value(s) for Beta, we have to use the following formula:
σ TE2=(1−β) 2 σ m2 +σ ε2
Here is the solution:
σ TE2=(1−β) 2 σ m2 +σ ε23.5²
= (1 - β)² × 20² + 1.5²12.25
= (1 - β)² × 400 + 2.25(1 - β)²
= 10/400
= 0.025
Taking the square root of both sides, we get:
1 - β = 0.1581 or -0.1581β
= 0.8419 or 1.1581

Find the angle θ between the vectors. (Round your answer to three decimal places.)
u = (−4, 2), v = (−1, 3)
The angle θ between the vectors u and v is approximately 27.598 degrees (or 0.481 radians) when rounded to three decimal places.
To find the angle θ between the vectors u and v, we can use the dot product formula:
u · v = ||u|| ||v|| cosθ
where u · v is the dot product of u and v, ||u|| and ||v|| are the magnitudes (lengths) of the vectors, and θ is the angle between them.
First, we need to find the dot product:
u · v = (-4)(-1) + (2)(3) = 10
Next, we need to find the magnitudes of the vectors:
||u|| = √((-4)^2 + 2^2) = √20 ≈ 4.472
||v|| = √((-1)^2 + 3^2) = √10 ≈ 3.162
Now we can substitute these values into the formula and solve for cosθ:
10 = (4.472)(3.162) cosθ
cosθ = 10 / (4.472)(3.162)
cosθ ≈ 0.887
Finally, we can use the inverse cosine function to find the angle θ:
θ = cos⁻¹(0.887)
θ ≈ 27.598 degrees (rounded to three decimal places)
Therefore, the angle θ between the vectors u and v is approximately 27.598 degrees (or 0.481 radians) when rounded to three decimal places.
To find the angle θ between vectors u = (-4, 2) and v = (-1, 3), we can use the dot product formula and the magnitudes of the vectors.
The dot product formula for two vectors u = (a, b) and v = (c, d) is:
u · v = a*c + b*d
For u = (-4, 2) and v = (-1, 3):
u · v = (-4)*(-1) + 2*3 = 4 + 6 = 10
Next, we need to find the magnitudes of the vectors:
||u|| = √((-4)^2 + 2^2) = √(16 + 4) = √20
||v|| = √((-1)^2 + 3^2) = √(1 + 9) = √10
Now, we can use the dot product formula and the magnitudes to find the angle θ:
cos(θ) = (u · v) / (||u|| ||v||) = 10 / (√20 * √10) = 10 / (√200)
θ = arccos(10 / √200) = arccos(0.7071) = 44.997 degrees
Therefore, the angle between the vectors u and v is approximately 44.997°, rounded to three decimal places.
